Hi Ronnie,
In VSDemo sample, we have used TabbedMDIManager and DockingManager to achieve your requirements. When TabbedMDIManager is used, Calling DockingManager.SetAsMDIChild() opens the UserControl as TabbedDocument.
Here is the code snippet :
private void button1_Click(object sender, EventArgs e)
{
UCTextArea uc1 = new UCTextArea();
this.dockingManager1.SetEnableDocking(uc1, true);
this.dockingManager1.SetAsMDIChild(uc1, true);
}
I have also attached the sample. Please have look at the sample and let me know if it helps.
