Update label value with asynchronous method issue.

Hi All, I want to update a label value from code behind by hitting the db. Since i want to improve performance, i am calling it with asynchronous method (with IAsyncResult, BeginInvoke and EndInvoke). I am getting the correct result, but since the page has already rendered, updating the label value is not getting effected. Can Someone help me to get this done? Thanks, Ketan ...
