Solution 1

Just Google/CP Search for 'Cascading Dropdown'.

What you are looking for is populating a second dropdown based on the value selected in first dropdown.

If not anything else, Ajaxtoolkit has a cascading dropdown[^] control.

On selected index change check the Selected Value of a DropDown List and according to that bind ur Further Drop downs!
