Pressing F2 in a gridview/treelistview selects all of the text in the cell when it goes into edit mode. I am trying to make it work like Excel and just select the end of the text, but I can't see any way to do this. If I click in the cell to edit it, it the cursor goes where you click rather than selecting all.

Hello Steve,

The gridview API doesn't allow changing this behavior. However, you can achieve your requirement by creating a custom column and override its PrepareCellForEdit method. There you can get the TextBox control and de-select its text. Here is an example in code:
public class CustomGridViewDataColumn : GridViewDataColumn
{
    protected override object PrepareCellForEdit(FrameworkElement editingElement, RoutedEventArgs editingEventArgs)
    {
        var cell = base.PrepareCellForEdit(editingElement, editingEventArgs);
        var tb = editingElement as TextBox;
        if (tb != null && !(editingEventArgs is MouseButtonEventArgs))
        {
            tb.SelectionStart = tb.Text.Length;               
        }
        return cell;
    }
}

<telerik:RadGridView.Columns>
    <local:CustomGridViewDataColumn DataMemberBinding="{Binding Name}" />
</telerik:RadGridView.Columns>

I've also attached a small example showing this approach. I hope it helps.
