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
