A critical feature of any data reporting tool is the ability to select specific data rows for detailed viewing or operations. In ASP.NET’s DataGrid, this is achieved through a selection mechanism that can be both declarative and programmatic.

  • Declarative Selection: Here, a button column with the CommandName property set to “select” is added to the DataGrid. This allows users to select a row by clicking on a button within that row.
  • Programmatic Selection: The SelectedItemIndex property of the DataGrid control can be set programmatically to automatically select a row based on certain conditions or user actions.

Styling the Selected Row

Once a row is selected, it’s often useful to highlight it visually. The DataGrid control provides the ItemStyle property to customize the appearance of rows, including the selected one. For instance, the background color of a selected row can be changed to make it stand out. This styling does not override explicit style settings applied to individual columns, ensuring that the overall design integrity of the grid is maintained.

Responding to Selection Changes: The SelectedIndexChanged Event

When a row is selected in the DataGrid, the SelectedIndexChanged event is triggered. This event can be handled in the ASP.NET code-behind to perform specific actions, like displaying more detailed information about the selected item in a different control, such as a details view or a modal popup.

Implementing Selection and Styling in DataGrid

Here’s a simplified example demonstrating row selection and styling in an ASP.NET DataGrid:

In this code:

  • A ButtonColumn is added for row selection.
  • The SelectedItemStyle property is used to style the selected row.
