Stopping a docked window being added as a MDI child

[Stephen Kew]

Hi,

I am using the DockingManager with the TabbedMDIManager and the problem I am experiencing is that with the Whidbey and VS2005 drag style providers, it is possible to drag a docked control and re-dock it as a MDI child window.

So in the case of the Visual Studio example, I would be able to dock the Solution Explorer so that it is tabbed in the MDI Client area with the C# source files. (see attached image)

I was wondering if there was a way for me to prevent that behaviour?

Thanks

Hi Stephen,

Sorry for the delay in getting back to you.

It is possible to prevent a control from being MDI child by handling the event DockAllow.Here is the code snippet.

private void dockingManager1_DockAllow(object sender, Syncfusion.Windows.Forms.Tools.DockAllowEventArgs arg){
//Prevents control pnlpanel1 from being MDI Child
if(arg.DragControl==pnlpanel1 && arg.DockStyle==DockingStyle.Tabbed ) arg.Cancel=true;
}

Attached sample implements this logic.Please take a look into that.

Thanks for choosing Syncfusion products.
Regards,
Joy
