How to call a client side javascript function after a specific UpdatePanel has been loaded

How can I defer loading UpdatePanel content until after the page renders?

Old hand at ASP.NET, new to the UpdatePanel. I have a reporting page which executes a fairly length SQL query… takes about 10 seconds right now.

How do I get jqGrid to work using ASP.NET + JSON on the backend?

ok, I’m back. I totally simplified my problem to just three simple fields and I’m still stuck on the same line using the addJSONData method. I’ve been stuck on this for days and no matter how I rework the ajax call, the json string, blah blah blah…I can NOT get this to work! I can’t even get it to work as a function when adding one row of data manually. Can anyone PLEASE post a working sample of jqGrid that works with ASP.NET and JSON? Would you please include 2-3 fields (string, integer and date preferably?) I would be happy to see a working sample of jqGrid and just the manual addition of a JSON object using the addJSONData method. Thanks SO MUCH!! If I ever get this working, I will post a full code sample for all the other posting for help from ASP.NET, JSON users stuck on this as well. Again. THANKS!!
