C# - TabControl TabPage's SelectedIndex

I have a program that has a tabControl in it, with a few TabPages and a few stuff on the out side of it.

I want to program a TabControl SelectedIndex Change or something like that.... What I want it to do is this:

I have two TabPages, if tabPage1 is selected then it enables some groupboxes on the outside of the TabControl (in the same Form), if tabPage2 is selected then the enable groupboxes = false. Can someone help me with that?

Answers


use the selectedindexchanged event

private void TabControl1_SelectedIndexChanged(Object sender, EventArgs e)
{
       MessageBox.Show("You are in the TabControl.SelectedIndexChanged event.");    
}

and check what the current index is from the sender object
