ListBox and CheckedListBox

Here we'll cover the aspects of C#'s list boxes and checked list boxes (ListBox and CheckedListBox controls).

Using the ListBox



We'll start with a 'Windows Application' project in Microsoft Visual C# .NET. Name it 'ListBoxes'.
To your newly created form add from the Toolbox a ListBox named 'itemList', a TextBox named itemName and three buttons named 'cmdAdd', 'cmdRem' and 'cmdClr'.

Your form should now look similar to this one:



All the action is started by the last 3 buttons we have added, of course.
New items can be added to the list by the programmer by selecting the list box and using the 'Items' property.



A window pops up, where you can enter new items to be displayed in the list box. Each line represents a new item.

Now arrives the important part: coding. We'll use the Click event of the 'cmdAdd' button to add new items to the list. Of course, the name of the item will be the text in the 'itemName' text box.

Double click the 'cmdAdd' button to get into the cmdAdd_Click event directly and use the following code:


private void cmdAdd_Click(object sender, System.EventArgs e)
{
    if(itemName.Text == "")
    {
        MessageBox.Show("Please enter a name.", "No name entered", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
    }
    else
    {
        itemList.Items.Add(itemName.Text);
    }
}



As you can see we first test to see if the text box in which the name of the item to be added to the list has any value at all.
If it doesn't (it is equal to "" - that is nothing) we popup an exclamation MessageBox with an OK button that asks the user to enter a name first.



If it has a value, the item is added to the list by using the 'Add()' method of the 'Items' collection.

The remove button acts similar.


private void cmdRem_Click(object sender, System.EventArgs e)
{
    if(itemList.SelectedIndex == -1)
    {
        MessageBox.Show("Please select an item first.", "No item selected", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
    }
    else
    {
             itemList.Items.RemoveAt(itemList.SelectedIndex);
    }
}



What does


if(itemList.SelectedIndex == -1)



actually do, you ask?

Every item in a list box has an index. The SelectedIndex property shows us which item is currently selected in the list box. If no item is selected the SelectedIndex property is set to -1.
We want to assure that an item is selected before trying to remove it, don't we?
This is why if no item is selected (SelectedIndex equals -1) we warn the user.



If there is an item selected we can safely remove it using 'Items.RemoveAt()' and passing the index of the selected item using 'itemList.SelectedIndex' property.

Finaly, we clear the list box using:


private void cmdClr_Click(object sender, System.EventArgs e)
{
    itemList.Items.Clear();
}



As you just saw, handling list boxes isn't so hard.

Using the CheckedListBox



Similar to its base class, ListBox but allows items to be checked using the checkbox next to each item, this way you can select multiple items.

Create a new project named 'CheckedListBoxes' and add to it a CheckedListBox and a ListBox. Name them 'checkedList' and 'selectedList'. Now add some items to checkedList (you can add new items just like you do when using a simple ListBox - from Properties choose Items, in the window that pops up every line represents a new item).
After you add some items to 'checkedList' your form should look similar to this:



We want every item that is checked in 'checkedList' to be added to the 'selectedList'.
This is easy to code by using the 'ItemCheck' event of our CheckedListBox.
With our CheckedListBox ('checkedList') selected go to the Events section and scroll until you find the ItemCheck event.



Double click the empty box next to ItemCheck. Microsoft Visual C# will automatically add the 'checkedList_ItemCheck' next to ItemCheck and the Event window will now look like in the picture above. Also Visual Studio will bring you to the part where you need to code:


private void checkedList_ItemCheck(object sender, System.Windows.Forms.ItemCheckEventArgs e)
{

}



The ItemCheck event occurs when a value is checked or unchecked in the CheckedListBox. We can use this to add checked items to 'selectedList' and remove them from there when they are unchecked.
We can use this code:


private void checkedList_ItemCheck(object sender, System.Windows.Forms.ItemCheckEventArgs e)
{
    if( e.NewValue == CheckState.Checked)
    {
    selectedList.Items.Add(checkedList.SelectedItem.ToString());
    }
    else
    {
    selectedList.Items.Remove(checkedList.SelectedItem.ToString());
    }
}


First we check to see the NewValue of the changed item represented by the 'e' argument. If its CheckState is Checked we can add it to the list by using the selectedList.Items.Add() method we learned earlier about.
We also need to convert the SelectedItem using ToString().
Else, if the item was unchecked we remove it in a manner similar to the one we used to add it, just that now we use the Remove() method.



The items are added to the ListBox in the order in which you select them.

Respected Sir,
I Want to know more about C#.
The above given notes was very helpful to me.
I want to know how the selected item in the checkedListBox can be displayed in a textBox or a MessageBox.
Please send me the instructions to my E-Mail id.
my E-Mail id is krmuthu14@yahoo.co.in
Thanking you,
Yours sincerely,
K.R Muthukumaran.

I emailed you but I'm also posting this here in case someone else needs it.

Add a checkedListBox and a textBox on the form, add a few items to the checkedListBox.
Then doubleclick the checkedListBox to get the default event (checkedListBox1_SelectedIndexChanged).This will take us to the part where we need to code.

The event that occurs every time when you select a different item from the list is called ‘SelectIndexChanged’. Every time this event occurs (you select an item in the list) we want to update the TextBox and display the name of the selected item.

For this we use the following code:

private void checkedListBox1_SelectedIndexChanged(object sender, System.EventArgs e)
{
textBox1.Text = checkedListBox1.SelectedItem.ToString();
}

As you can see, in the line:

textBox1.Text = checkedListBox1.SelectedItem.ToString();

…the textbox is updated so that it contains the text of the currently selected item in the checkedListBox.
We also use ToString() because we want the result as string in the textbox.

Add the following line to display the result in a MessageBox:

MessageBox.Show(checkedListBox1.SelectedItem.ToString());


Good luck.

Andrei Pociu.

Hmm..
I've got simliar.. but further problem.
What about if check box list items are connected to the data base, then binded. How can I preselect the check boxes at page load, what ever values in the database?

by Andrei Pociu on Friday, May 28th 2004 at 05:42 AM

You can add a field to the table that will hold a binary value 1 or 0 if the item in the checkedListBox is checked or not checked.
Loop through the rows and set to 'if' conditions. If the value in the row is '1' then:
if(....)
{
checkedListBox1.SetItemChecked(currentItem, 1);
}
else
{
checkedListBox1.SetItemChecked(currentItem, 0);
}

Tell me if you need further help.

by melissa on Tuesday, June 1st 2004 at 06:36 PM

I don't know how to set my if statement condition.
I will have two tables: Person and Interest.
On a person detail's there will be list of interests on a CheckedListBox, then whatever value in the person table-interestID(fk) are cheked on the page load. Another words, what ever the interests of a person in the person table, are checked.

Thank u so much for your help.

by Rajesh on Tuesday, June 8th 2004 at 12:09 AM

I have a list of Clients in the checked list box. All the clients are selected. If i deselect a client from the list box how shall i come to i have the right client data that i have deselected.bcoz i want that data to send to data base for deletion.

by melissa on Tuesday, June 15th 2004 at 08:41 PM

it's me again.. don't get sick of me=p

Do you know how to get the value of CHECKED items' indices (Eg. 1,2,5,...) of a CheckedListBox?

Thanks again=)

by Andrei Pociu on Tuesday, June 15th 2004 at 09:15 PM

You use checkedListBox1.SelectedIndex.

In our example where we have:

if( e.NewValue == CheckState.Checked)
{
selectedList.Items.Add(checkedList.SelectedItem.ToString());
}

if you want to see the index instead of the value use this:

if( e.NewValue == CheckState.Checked)
{
selectedList.Items.Add(checkedList.SelectedIndex.ToString());
}

by Sirrurg on Thursday, June 17th 2004 at 09:24 AM

Hi!

Hopefully u can help me. I want to make a selection through a checkedListBox like shown above, but i have one item in my checkedListBox called "all". If this item is selected i want to unable all other selection/checkboxes as it doesnt make much sense to make more selections.
Is there any "easy" way to do so ? I havent found a property to access this boxes to do so.
Thanks,
sincerely
Sirrurg

by Cezar Tipa on Tuesday, July 6th 2004 at 01:45 AM

The trick with e.NewValue is excellent to use with ListView.ItemChecked which is an "after event" event.

by JIm on Friday, September 24th 2004 at 01:58 AM

The checklistbox demo.
I cant seem to find "itemcheck" property when selected the checklistbox control.
I have also double checked another another's VS .NET.
Please tell me where and how to make checklistbox work when unchecked the item, it will remove the item in the listbox.

by Andrei Pociu on Friday, September 24th 2004 at 07:46 AM

I think I know what you're doing wrong, you're looking at properties instead of events, as there is no ItemCheck property, there is only an event.

So click on the 'thunder' icon in the properties window and there are the events and the ItemCheck event.

Good luck!

by Jim on Friday, September 24th 2004 at 01:05 PM

A THOUSAND THANKS! I got it now.

There's a tutorial covering this:

by satya on Tuesday, November 23rd 2004 at 03:58 AM

I worked with ListBox and it has drawmode property.
But checkedListBox control doesnot have DrawMode property. And always this property will be set to Normal.
Hence checkedListBox colors cannot be customised.

However, i decided to work with round-about the solution,
a groupbox with check boxs. If time permits i will make this as a component.

by Sunita on Tuesday, November 30th 2004 at 10:55 AM

Hi,
I would like to know if I have a Valuemember property attched to a checkedlistbox, how can I get the value of the Valuemember when the item is selected.
For eg. the Display might just show "Amazon" but I want to get the Valuemember which might have a value of say '5'. Thanks in advance for your help

by Hicham on Sunday, December 12th 2004 at 11:41 AM

Hi,
I want to retrieve all the items selected in the checkedlistbox.
Actually, when I use this.checklistbox1.SelectedItems.CopyTo(array,index)
it does only copy the last element checked

Hi,

How to bind CheckedListBox with Dataset?
When i create a CheckedListBox control i dont get its Datasource prperty..
Please help me.

by Syed Irtaza Ali on Monday, February 21st 2005 at 05:45 AM


Hi,

Visit this link for my article on Databinding CheckListBoxControl with DataView

http://blogs.wdevs.com/irtaza/articles/2203.aspx

Using .NET standard CheckedListBoxControl, I couldn't find the properties DataSource, DisplayMember, and ValueMember. Probably the reason would be an older .NET Framework. So instead of getting into the hassle I decided to use the DevExpress CheckedListBoxControl.

Hope this helps out.

by Nick on Tuesday, February 22nd 2005 at 05:31 AM

I am trying to use the Checked list-box control in the C# windows project, but unable to get the datasource, displaymember, valuemember properties. But when I use the Checked list-box control in the windows forms project using VB.NET the above properties appear. Is this a bug with the control or is there a Ghost In My Machine.

Cheers!!!

How can I get multiple selections within a listbox to appear in a textbox with a comma and a space between each selection?

by Andrei Pociu on Saturday, April 23rd 2005 at 02:51 AM

Here's how (sorry, no code but you can find on Google):

- set the MultiSelect property to true
- iterate through the array of selected items (using a foreach perhaps)
- add the selected values to the textbox plus the comma

So the key is to iterate through all the selected items.

by Jon on Saturday, April 23rd 2005 at 04:14 PM

Still can't get it to work. I'm still new to C# but this is what I have:

for (i=0; i>25; i++)
{
if (genres.Items[i] == genres.SelectedItem)
{
selectgenres[x] = genres.Items[i] + ", ";
x = x + 1;
}
}

genres is my listbox, selectgenres is my string array.
I have 25 items in my listbox, hence the i>25.
I'm not sure how to get the genres.Items[i] to turn into a string.

I would like to know if I have a ValueMember property attched to a checkedlistbox, how can I get the value of the ValueMember for the Product which is stored in Database
For eg. the Display might just show Product as "Cough Cyrup" but I want to get the Valuemember, i.e., ProductCode which might have a value of say '3'. Any help will be appreciated.

I'm trying to make a checkedlistbox so that the items in the list cannot be checked or unchecked. I have tried setting enabled to false, but this disables the scrollbar. It needs to be scrollable but not able to be checked.

Any ideas on how to do this?

Hi,
please i need a solution for this

I have mentioned checkedlistbox1.datasource = ds.tables(0)
CheckedListBox1.DisplayMember = ds.Tables(\"second\").Columns(\"name\").ToString
the table has two rows one column is true or false
and the other column is the name

According to the first column whether its true or false, we need to check the item in the checkedlistbox1 i.e checked if true and un checked if its not true
and the actions taken in the checkedlistbox also should reflect true or false in the table

thanks

Hi,

I am having a problem with link lables. I have been trying and trying with no luck. I need to create a link lable everytime the user clicks on the button Create. I can create 1, but this need to be dynamic where the user can create 30 or delete 10 (whatever the case maybe). These links then point to certain files on the Harddrive and are opened in my program. I would like to have the links added to a Listbox or Datagrid. I have searched the Internet for any articles regarding this with no luck what so ever !

Please help

Regards,
Darren

hi all.
In VB.NET, i want to create a checkedlistbox that contains some items. some of the items is checked based on some condition. if the item is checked, i don't want user to unchecked it, so i need to disable the checked item.
Is this possible with the CheckedListBox control in VB.NET? Thanks.

by Melani Marakkala on Wednesday, April 25th 2007 at 06:23 AM

Sir,
in my C# project,I have added a check box with a button.What it has to do is, when you put a tick on the checkedlistbox item, the selected items shuld display in a text field (In a button click event). and also in the same event (Button click event) i need to deselect all selected values in that checklist box.

ie: actually I need to reload the same checkedListBox as a refreshed one.
How can i do it?

Please answer me soon.

This may help you in retreiving the values from the database into a checkedlistbox.

Int itemindex;
DataSet ds = new DataSet();
ds = /*** Your function which retrieves the data through SQL Query from the database . this function should return a dataset ***/

foreach (DataTable table in ds.Tables)
{
foreach (DataRow row in table.Rows)
{
ListItem item = new ListItem(row[0].ToString(), row[0].ToString());
this.mycheckedlistbox.Items.Add(item);
itemindex = mycheckedlistbox.Items.IndexOf(item);
mycheckedlistbox.Items[itemindex].Selected = true; /** If you want to make it appear as checked **/
}
}

I have a DropDownList of drivers, which upon selection of a driver, displays a ListBox showing deliveries from a DataSource for that driver. Below that, in a form, we have a CheckBox that "closes" the delivery on completion. We want to remove the listed item from the list. Essentially this works, but the item stays listed until you select a different driver (go out and come back in). An overall page refresh doesn't clear the item. If you have any suggestions, I'd really appreciate some pointers. I'm pretty new to this stuff.

Thanks in advance.

I am generating a string by combining the values from 5 text boxes items in a CheckedListBox (chkTLD). I want to write the strings I create to a ListBox(itemList).

I am able to generate the string when 1 item in the CheckedListBox (chkTLD) is checked. However, when I check multiple items in chkTLD, only the last item selected is displayed in itemList. I want all iterations to display at once in the ListBox(itemList).

I have an event called generate() that is envoked by hitting the Create button on my form. I don't know how to create multiple strings from having multiple tld items selected. Can you help?

Code is below:


protected const string TEMPLATE = "{0}-{1}-{2}-v{3}-{4}{5}";
private void generate()
{

string testName = txtName1.Text.Trim();
string testType = txtName2.Text.Trim();
string testNumber = txtTestNumber.Text.Trim();
string versionNumber = txtIteration.Text.Trim();
string tld = chkTLD.Text.Trim();
string dateString = DateTime.Now.ToString("yyyyMMdd");
object[] parameters = {
testName,
testType,
testNumber,
versionNumber,
dateString,
tld
};
string domainName = string.Format(TEMPLATE, parameters);



if (chkTLD.SelectedItems == null)
{
MessageBox.Show("Error", "TLD is required", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
else
{
itemList.Items.Add(domainName);
}
}





private void btnCreate_Click(object sender, EventArgs e)
{
this.generate();

}

by re on Friday, March 19th 2010 at 11:52 AM

private void chkLB1_ItemCheck(object sender, ItemCheckEventArgs e)
{

if (e.NewValue == CheckState.Checked)
{
MessageBox.Show(chkLB1.SelectedItem.ToString() " ON");
}

else
{
MessageBox.Show(chkLB1.SelectedItem.ToString() " OFF");
}

}

by Chris on Friday, March 19th 2010 at 01:34 PM

thanks for the info, but that just displays to a msg box of only the CheckedListBox value.

I want my generate() method to write all the strings that are created from my CheckedListBox selections to my ListBox. As written, it just writes last item checked, not ALL items checked.

by pete on Friday, March 19th 2010 at 02:19 PM


int car = txt1.Text.Length -1;

word = txt1.Text.Substring(i, caract2);

if (word == txt2.Text)
{
cont= cont 1;

}
}
MessageBox.Show("there are " cont " " txt2.Text );

@megha:
The way I read your question, I'm able to interpret it a number of different ways. Regardless, you're asking if there is a way for a list to contain two objects within each item. What I'm not able to discern is whether you:
A) want to display both objects in the list (ie as two independent columns that mimic or share actions (ie scrolling, selecting, etc. )
B) want to display only one of the objects, but still be associated with the other object
C) want to concatenate the two objects into a simple string object to be displayed by the listbox.
D) want to concatenate the two objects into a string, but retain the original objects to be accessed by functions acting on the list without parsing the string and searching for the members individually.

Those theories are how you will go about your solution, as I don't want to delve into it anymore than I have to without knowing exactly what it is you're attempting.

I am trying to use checklistbox but nothing is working out. I am from India, so I came to here from Google.
