RowActivated Clearing out SelectedItems

[Darryn]

I have the following code in my RowActivated EventHandler

private void dgv_RowActivated(object sender, Telerik.Windows.Controls.GridView.RowEventArgs e)

{

            dgv.SelectedItems.Clear();

 

                foreach (var t in collection)

                {

                    dgv.SelectedItems.Add(t);

                }

}

I have SelectionUnit="FullRow" and SelectionMode="Extended" 

The problem is that the rows are highlighted for a second, then only the row I double clicked on remains highlighted. Is there any way to do this?

Hello David,

Generally, when working with Extended selection, the items will be selected when using key modifiers Ctrl or Shift. You can test the behavior on our demos. You can try working with Multiple SelectionMode instead. 
However, since selection is executed on clicking on the items, I am not sure that you will not break the functionality and result in an undesired behavior. Could you clarify what is your exact scenario so that I could try assist any further ?

I am trying to have it that when a user double clicks on a row, it will select that row, as well as all the other matching rows (based on my business logic).

Hello,

Unfortunately RadGridView.SelectedItems collection is read only, and you cannot add items to that collection. However you can take a look at this blog post for an idea how you could sync SelectedItems with a view model.
