    I noticed that one of my dropdownlists always posts back instead of doing an asynchronous refresh of the updatepanel.When I remove ClientIDMode="Static", everything works fine.

    Hello Madani,

    I have tried to reproduce the unexpected behavior but to no avail. You can find a short video with the test as well as the VS example that I have used for the test in the attached archive. I am using two asp dropdowns, decorated by the RadFormDecorator. The first one is inside an UpdatePanel that has its ClientIDMode set to "Static". When you select items from the dropdown, a partial postback is performed. The other dropdown is outside the UpdatePanel, so it performs postback when you select its items.

    Could you please try to reproduce the issue with this example and then tell us what changes you have made, so that I am able to reproduce it either and proceed further with the investigation? You can also send us a fully runnable sample with reproduction steps of the issue, if it is more convenient to you.

    All the best,
