Hi guys,

I'm having a little trouble trying to get the RadDock working.

Here is my scenario:
I have a windows form which contains a RadPageView. Inside one of those tabs I have multiple RadSplitContainers which are giving me left, center, right and bottom panels. The left, right and bottom ones are fixed with the center expanding with the form/window. In each of these I need to house UserControls or Forms.

But how?

I've dropped a RadDock into a panel and set it to fill the parent. I've then created both a UserControl and a Form which at run time (Form1_Load) either one gets inserted into the RadDock. Something like this (ucBBMain is my UserControl):

UserControl uc = new ucBBMain();
radDock1.DockControl(uc, DockPosition.Fill);

But I get an  error:
"Invalid DockTabStrip for a DockPosition.Fill operation."

I also tried this but get the same error:
UserControl uc = new ucBBMain();
HostWindow host = new HostWindow(uc, DockType.Document);
radDock1.DockControl(host, DockPosition.Fill);

Very same happens with a Form.

So how can I put UserControls or Forms into a RadDock where their size is expanded to the RadDock they are inside?

Or in fact is a RadDock the correct control to use? Can I put a UserControl directly into the SplitContainer panels?

Hello Sacha,

To dock a control with DockPosition.Fill in RadDock control you must specify the type of the new window as a Document. Here is a sample example:
I hope this helps. Let us know if you have any other questions.
