.Net user control in dockable window

[nmunro]

Does anyone have a pointer to an example of using a user control in an Inventor dockable window. If I create an instance of my user control and use myDocableWindow.AddChild(<ctrl>.Handle), it acts as if the control is a dialog rather than a user control (i.e. myDocableWindow.Control returns null). I've searched high and low but there does not seem to be any examples of this out there.

Hi,

I believe you asked a relevant question through ADN a few days ago :-). I found the comment may be simlar for this question. i.e. The DockWindow.Control returns the control which is registered. When using AddChild(<control>.Handle), this just refers to the user control class. So, if you AddChild(GUID of the control), the DockWindow would remember the control. I verified it at my side.

'Call oWindow.AddChild(m_control.Handle)

Call oWindow.AddChild("{C75A15CF-DF21-3EB7-AADF-48441AA55CCD}")

' now, the control is NOT nothing

Dim oControl As Object = oWindow.Control
If Not oControl is Nothing then
     Dim oUserControl As UserControl = oControl  
     MessageBox.Show("control handle:" + oUserControl.Handle.ToString())
End If

Hope this helps.
