Solution 1

I think, you are setting the intial value in page load itself.
So, whenever the page is posted back, selected index is set to default vaue 0.

Put a if condition to check post pack
Ex: if (Page.IsPostback)

For that please take a required field validator and set its control to validate property to DropDownlist1 and Set Initial Value as choose--langauge

It will help You
