I'm creating a web part (with a RadGrid) which implies that there is no designer to assist with development. So all coding is done programatically.
I am displaying records from a SharePoint list and there are too many fields to show all of them in the grid. So I have a RadGrid and a few text fields below it, where I would like to display fields that are not shown in the grid control. My question is simply whether there are any good examples or documentation on how to implement Ajax and/or UpdatePanel programatically. All examples I've found through a fairly extensive search all utilize xml coding.
A related question regarding web parts is where would the xml code need to be added if this is created using xml instead of programatically with C#? An aspx page is not associated with a web part (at least until the web part is added to a page) and I am not aware of an associated ascx file. There is a feature.xml and the xml based .webpart file, but neither of these appear to be the location to add xml code for a web part. I can add this second question as a separate thread if required.
Any assistance would be greatly appreciated.
