I found a problem while switching tabs of UltraWebTab

It could not generate TabClick event when I clicked tab between tabs.

My program has a button which is used to close tab.

If I cannot grab TabClick event, the button does not know which tab needs to be closed

Please feel free to tell me how to solve it.

first you must registred any click-event. open your site on design mode and select on context menu the quick design mode. here you can create a client site event.

when you call the ultra webtab control from client site, you must call the ultra webtab control. infragistics controls suported a very good object model. please read the javascript files on your pc in the infragistics directory. you can also create a custom client control. please look on my website: http://www.drescher-hackel.de/default,date,2007-07-22.aspx

If you are never getting the TabClick event to fire, try this:

In Visual Studio, go to the properties box for your WebTab object.

Set the AsyncMode to ON
Set Autopostback to TRUE
Expand AsyncOptions, and set EnableLoadOnDemand to TRUE
