Description

How to disable the text selection when a cell enters edit mode by pressing the F2 key.

Solution

1. Create a custom RadGridView column and override its PrepareCellForEdit method.
2. In the method override, get the editing element (TextBox) and manually set its SelectionStart property.

• C#

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; 
    } 
} 

• XAML

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