Answer
Hi

It's important to know which events are fired when a user changes the dropdownlist.

First, in the Page_Load, you should check for a postback. If it's a postback, then don't bind data to the dropdownlist. This will prevent the user input to be overwritten.

After that, create an event handler for the Drop down list changed, In this event, you can get the selected index in your dropdownlist.

Happy Programming!!
