Question

I have a C# program that has two forms. One form contains tab control and the other is a standalone form with many controls.

The question is: Is it possible to integrate this form into the tab control of the first control of the first form or I have to rewrite all the code and put them into the tab control?

I use C# Visual Studio 2010.

Answer 1

Generally, it is possible. However, I would strongly recommend that you do not use parented forms. Instead, move controls to the UserContol and add instances of this UserControl to the second form and TabPage of the TabControl.

Here is the code showing how to add a control to the TabPage:

Form f = new Form();
            f.TopLevel = false;
            f.BackColor = Color.Green;
            f.Visible = true;
            tabPage1.Controls.Add(f);

But, I strongly recommend that you use the UserControl based approach.
