Embedding WPF Control into IComPropertySheet

Question

Hi,
 
I have seen samples that embed classes (implementing System.Windows.Forms.UserControl, IComPropertyPage) into IComPropertySheets. Can we user WPF UserControl instead of Windows Forms Control to embed into IComPropertySheet.

Hi Gray,
 
Thanks for your reply again.
Let me try ur approach. But I doubt whether i can embed the default behaviour of the WPF Controls. e.g. If the Control is Listbox and Down key is pressed, will the next item get selected by default or I need to write code for that too.

Yes the whole keyboard events in controls is a bit of a mess. I get that problem with a windows control too. I did something like this in the windows control. Basically create my own handlers. I don't have list boxes but I think that is just the up and down keys. Public Sub Initialize() WorkaroundTabIndexDefect() End Sub '''

''' Works around the tab index defect. '''

Private Sub WorkaroundTabIndexDefect() For Each ctr As Control In Me.Controls SetKeyDownHandlers(ctr) Next End Sub '''

''' Sets the key down handlers. '''

''' The CTR. Private Sub SetKeyDownHandlers(ByVal ctr As Control) Dim txtCtr As TextBox = TryCast(ctr, TextBox) If txtCtr IsNot Nothing Then txtCtr.AcceptsTab = True txtCtr.AcceptsReturn = True Dim evh As KeyEventHandler = New KeyEventHandler(AddressOf WorkaroundKeyDown) AddHandler txtCtr.KeyDown, evh Else ctr.TabStop = False End If If ctr.Controls.Count > 0 Then For Each subCtr As Control In ctr.Controls SetKeyDownHandlers(subCtr) Next End If End Sub '''

''' Workarounds the key down. '''

''' The sender. ''' The instance containing the event data. Private Sub WorkaroundKeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Try If Me.ActiveControl IsNot Nothing Then Select Case e.KeyCode Case Keys.Return Dim btnCtr As Windows.Forms.Button = TryCast(Me.ActiveControl, Windows.Forms.Button) If btnCtr IsNot Nothing Then btnCtr.PerformClick() End If Case Keys.Tab If e.Shift Then Me.SelectNextControl(CType(sender, Control), False, True, True, True) Else Me.SelectNextControl(CType(sender, Control), True, True, True, True) End If End Select End If Catch ex As Exception Trace.WriteLine(ex) End Try End Sub

Hi Gray,
 
Thanks for your reply.
I have started implementing but have problem with Key events as you have montioned. To be specific, I have a listbox with items added to it. I have selected an item in the listbox and pressed Down/Up key. I expect that Next/Previous item to selected in the listbox. But the focus is moving to the parent Tab (Property Page) though the currenly selected item is in the middle. Neither Tab key works to navigate between the WPF controls in the Property Page.
I have checked the 2nd approach mentioned in ur ealrier post but no improvement.
 
Any suggestion to overcome this.
 
Thanks in advance.
