C# – Hide Tab Header on C# TabControl

ctabcontrolwinforms

I am developing a Windows Form Application with several pages. I am using a TabControl to implement this. Instead of using the header to switch between tabs, I want my application to control this e.g. the next tab should open after the user has filled in a text box and clicked the next button.

Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form. It shows the tabs at design time so you can easily switch between them while designing. They are hidden at runtime, use the SelectedTab or SelectedIndex property in your code to switch the page.

using System;
using System.Windows.Forms;

public class TablessControl : TabControl {
  protected override void WndProc(ref Message m) {
    // Hide tabs by trapping the TCM_ADJUSTRECT message
    if (m.Msg == 0x1328 && !DesignMode) m.Result = (IntPtr)1;
    else base.WndProc(ref m);
  }
}
