I have 3 asp:drop down lists. DropDown2 values on DropDown1 selected Item.
Dropdown3 values depend on dropdown2 selected item. I implemented the functionality using onchangeindex functionality. But it is doing pagerefresh on each dropdown item selected.
I want to implement call back for this funtionalty to aviod page refresh.
can some one share the code.
