How to cancel a Selected Tab Index Changed

I have a panel inside of a Tab, and the data may or may not valid based on the user input.  When a user tries to click onto a different tab, I want to check to make sure ValidateData() is true before allowing them to switch tabs.  Is this possible?  Can I somehow cancel the tab changing event?

This would be simular to something I asked a while back and you could do simular type thing.  Check this out:

Just disable all the other tabs until you have validated and then you can enable them again to allow the change...or something more custom could be done.

Hope that helps,
Add this event to the tabControl:
      tabControl.SelectedIndexChanged += new System.EventHandler(OnSelectedIndexChanged);

And this code:
            private int nPrevTab = -1;
            private void OnSelectedIndexChanged(object sender, System.EventArgs e)
                  if (!ValidateData() && nPrevTab != -1)
                        ((System.Windows.Forms.TabControl)sender).SelectedIndex = nPrevTab;
                        nPrevTab = ((System.Windows.Forms.TabControl)sender).SelectedIndex;
