Question

Is there a way to display Windows Form inside a tabpage of another Windows Form?

I know this is a rather old post, but I am desperate. I am creating a similar UI (i.e display ChildForms in TabPages) and have used similar coding. Now I don't want to create multiple instance of the same ChildForm/TabPage). If the user chooses a menu for the first time, the corresponding Form should be created and displayed in a TabPage. (I am OK upto this point). I want to allow the user to display different Forms at the same time (each in its corresponding TabPage). But if the user chooses the same menu option, then the already created Form/TabPage should get displayed and not create a new one. I am unable to implement this feature. Can anybody please help me.

Hi again, I found the solution to this on another forum by using this. Form2 frm = new Form2(); frm.TopLevel = false; frm.Visible = true; frm.FormBorderStyle = FormBorderStyle.None; frm.Dock = DockStyle.Fill; tabControl1.TabPages[0].Controls.Add(frm); Hope this helps someone else also.

No, a form is considered a top level control and it cannot be added to the control collection of a tab page. Can you build a user control that contains the same UI and code to replace the form? You can put that into a tab page.
