Answer 1

you can use the below code inside the event block to check whether the SelectedIndexChange event is firing directly because of the control or due to some postback event from some other usercontrols/Pages

string id= Request.Form["__EVENTTARGET"];

if(!string.IsNullorEmpty(id))
{
//your code here
}
