Solution 1

Google for Cascading dropdown.

What you need is to fill the other dropdown based on previous drodown selected value. For this, you can use Javascript, AJAX UpdatePanel, AJAX PageMethod, Client Callback or a normal postback.

Give a try, if you face any specific issue while doing it, do share with us.

Solution 3

Define OnSelectedIndexChanged event of the dropdown. Make sure you turn AutoPostBack="true"and in the code behind get the selected value and retrieve the dataset result based on user's selected value and then refresh the datasource. Makes sense?
