Hi,

I guess you are loading your dropdown in all the pageloads, irrespective of whether its a post back or not.
You can load your dropdown only if its a initial page load and not a post back.
like,

C#

if(!IsPostBack)
{
//then your code here
}

Hope this helps.

Once you fix this problem, you should be able to get the selected item in your index change.Can you post your code for the button click and the selected index change?
