Hi Umbala,

Could you please provide more information about this problem? What is the expected behavior when Control +Shift + C buttons are pressed?

I cretate a new child window and put a RadGridView on it. I handler Keydown event to close from but Ctrl + Shift + C don't work

Code behind :

Private Sub Window_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Input.KeyEventArgs) Handles Me.KeyDown 
    RouteKeyDown(sender, e) 
End Sub 
Private Sub RouteKeyDown(ByVal sender As Object, ByVal e As System.Windows.Input.KeyEventArgs) 
    Dim keys As ModifierKeys = Keyboard.Modifiers 
    Dim shiftKey As Boolean = (keys And ModifierKeys.Shift) <> 0 
    Dim altKey As Boolean = (keys And ModifierKeys.Alt) <> 0 
    Dim controlKey As Boolean = (keys And ModifierKeys.Control) <> 0 
    'Ctrl + Shift + C  
    If e.Key = Key.C And controlKey = True And shiftKey = True Then             ' don't work
        Me.Close() 
    End If 
    If e.Key = Key.U And controlKey = True And shiftKey = True Then              ' work fine          
        Me.Close() 
    End If 
End Sub

Hi Umbala,

RadGridView will handle events for keys like Control, Shift, etc and those events will not reach the window. You can workaround this by subscribing to those event in code using the AddHandler method and suppling true as last argument. For example:

Imports System
Imports System.Linq
Imports System.Windows.Controls
Imports System.Collections.ObjectModel
Imports System.Windows.Data
Imports Telerik.Windows.Controls
Imports System.Windows
Imports System.Windows.Input
  
Namespace SilverlightApplication1
    Public Partial Class MainPage
        Inherits UserControl
        Public Sub New()
  
            Me.[AddHandler](FrameworkElement.KeyDownEvent, New KeyEventHandler(OnKeyDown), True)
        End Sub
  
        Private Sub OnKeyDown(sender As Object, e As KeyEventArgs)
            ' TODO: Implement this method
            Throw New NotImplementedException()
        End Sub
    End Class
End Namespace
