Hi Every one,
i am trying to create a UserControl and i am passing a Array of strings to
it. Now based on the Array elements i am creating the LinkButtons
Dynamically. I am also passing a Event to this control and Lining the
OnClick event of these LinkButtons to this Event. (Which works fine).
Now the Thing which i cannot achieve is i want to Change the Back Color of
the Clicked to LinkButton To a different color and i also don't want to
Display the clicked item as LinkButton. and i am not able to do that. Looks
like i am missing some thing here. Please Help me..
Here is the code of all my Files.
1:- test2.aspx File. ( in this file i am calling the Control)
