[Solved] How can I limit the expanded rows to just one

[Abhishek Gairola]

I am using

GridViewToggleRowDetailsColumn

However I want that at a time only one row should be expanded.
If user tries to expand a second row the the event should be cancelled.
Once user has collapsed the row then he/she can expand another row.

Version 2009.3.1208.1030

Can anyone please help me with this functionality?

Hello Abhishek Gairola,

You need to handle the RowDetailsVisibilityChanged event and ensure that the previously expanded row is collapsed, while the new one is expanded. For example:

GridViewRow expandedRow;      
private void clubsGrid_RowDetailsVisibilityChanged(object sender, Telerik.Windows.Controls.GridView.GridViewRowDetailsEventArgs e)

{

            if (e.Visibility == System.Windows.Visibility.Visible)

            {

                if (expandedRow != null)

                {

                    expandedRow.DetailsVisibility = System.Windows.Visibility.Collapsed;

                }

                expandedRow = e.Row;

            }
}

 

All the best,
