Please follow this steps..

1) first of all you need to add one property to your first drop down
AutoPostback = true

2) now you need to set your selectedindexchange event of your first drop down

3) in selected index change event writer your code fro data binding for your second dropdwon as per the first dropdwon selected value or in-case selecteditems.text

4) this way you can perform your corresponding data binding of two drop downs...
