Linked DropDownList

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :ASP.Net

I have three DropDownList which are linked. On an edit however when you change the first DropDownList it gives an error because the second has a value which is not part of the list generated from the first Dropdownlist. I have tried changing the value of the second to null on the OnSelectedIndexChanged event but this isn't fixing the problem.
