Improving performance of nested dropdownlist in asp.net 2.0

I have a series of nested dropdown lists, each time when I select an item from the dropdown list it consumes a lot of time as I am binding other dropdowns based on the selection in pageLoad.

Is开发者_开发技巧 there any way I can improve the performance?

Without code, it's hard to formulate an exact answer, but in general terms, you could implement page methods and ajax. That would do the trick.
