Question

I googled this and still cant get it to work. I know how to add a tab using the toolbox. I have also read about how to do it programmatically, but i still dont get it. (MSVC# Express 2010)

I have an easy project set up. Just a windows Form with a TabControl in it, i used the Designer to add a new TabControl and made that TabControl public instead of private.

I wrote this code to
a) access the Windows Form
b) add a tabpage.

The code compiles just fine, but the Tabpage is not displayed during runtime.

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.SetCompatibleTextRenderingDefault(false);
        Application.EnableVisualStyles();
        Form1 ApplicationMainForm = new Form1();
        Application.Run(ApplicationMainForm); //LABEL B

        ApplicationMainForm.tabControl1.TabPages.Add("MyPage"); //LABEL A
    }
}

How can i get the form to display my Tabpage?
My TabPage is displayed when the Lines A and B change position. Am i missing an update method, oder is the TabPage Add never called until the application closes?

Answer 1

Form1.tabControl1.Controls.Add(myNewTabItem);

The tab control is a collection of tab pages, so you add tab pages like you add any control to a collection. Note that the tabs show up in the order you add them.
