I don't think there is any event specifically for a tab being clicked, but if the tab was not selected previously, clicking the tab will select it and fire off the SelectedTabChanging and SelectedTabChanged events.
Hi,
Thanks much for your answer. I 'd like to know one more thing. Which event will fire when user click on the header of a Tab in UltraTabWorkSpace?
Your help will be highly appreciated.
Thanks
Once you have a reference to the tab, you can get it's TabPage property. That control will have one child control, which will be the smartpart associated with the tab.
