I'd recommend a simple if or case statement (whichever you prefer) to identify the current selected tab. switch (tabControl.SelectedIndex) { case 0: //do stuff break; case 1: //do some other stuff break; } This would work under the assumption that you were using the tab indices to find out what's currently selected. There's also a function that allows you to check the current tab by its name. It'd work in the same respect as the .SelectedIndex function, expect you'd be using the tab names rather than the indices. It's the .SelectedTab function. I hope this was of some help. Happy programming! :)
