I have use a update panel with trigger and timer to rotate images in banner.

Now in another update panel I have three dropdownlist (Country , State , City).

But in after a first times it displays all three dropdown twice.

How to solve this issue?

1 solution

By fixing your code. Not using update panels and writing your own AJAX code is a good start, but certainly not showing us the code, is not going to help. Use Chrome to debug your code on the client side and you should be able to see why it's triggering twice.
