I have a dropdown box on a custom webpart and I am initially filling it out with server side c# code in the createchildcontrols section. I wanted to cascade the dropdown to fill out another dropdown. This works fine if I do it all in .Net except the annoying postback refresh of the entire form which the customer does not like. I know how to achieve the same effect using jQuery and attaching an onchange event. This does fill out the second dropdown without an issue. However, if I do this with jQuery my button event on the form no longer fires and I can not save the data. Has anyone else seen this or am I missing some setting that will allow this to occur?
UPDATE: 3/12/2010 Okay, so I still have the issue, but what I have done is actually proved that the button click does fire, but it does a postback and does not actually run the code for the button click event. So I get a postback which I tested and know that the request object is working. This is not what I want to do as the controls are no longer available and the button event is what I wanted to actually use to read the controls and validate and then add to the list. If I go back to pure asp.net and do not use the jQuery, it all works fine.
