Is there any relation on this two drop down list... ??

It seems you have a full page post-back every time you select a new value - think about AJAX...

Pls post your code behind!

please remove the change event code from code behind and again create method by double clicking the two dropdown boxes.

Solution 2

Put a control panel around the ddlsoldrent control then add a trigger containing ddlflatshopename's SelectedIndexChanged event.
