I have two modules, a results module and a search module.  The search module exists on every page, the results is only on one page.  If the user performs a search I want to display the results module if it is not already loaded, but if it is loaded use a postback to refresh the results.

How can I cause a postback to the results module when the user clicks a button on the search module.  Because they are on the same page, I can see the code behind executing, but the results module doesn't refresh.

Any help would be great.

Thanks Chris.  I was able to get the results I am looking for by adding a javascript ajaxrequest from the first module and adding the second module's control as the target.

I'm still pondering the pros and cons of having one module's postback causing all other page modules codebehind to fire without the appropriate refresh.

Thanks again.
