ASP.Net 2.0: Can an UpdatePanel be placed inside a Control?

Hi all,

I recently discovered the power of ASP.Net AJAX Extensions and re-architected my site to take full advantage of it. I want to say Kudos to the DevDiv guys in MS to create such a powerful toolkit!

I converted most of my custom controls to use the AJAX ScriptLibrary and it is working very well. However, I noticed that if I place the UpdatePanel inside the control, the AJAX postback does not work and results in the whole page being updated. If I move the UpdatePanel back to the container ASPX Web Form, then the AJAX call works again. Is this somehow by design?

The really strange part is that I can place the UpdateProgress control inside my custom control and it still works, but I need to place the UpdatePanel outside of the custom control for the AJAX to work properly. Ideally, I would like the control to have its own UpdatePanel and UpdateProgress so I won't have to manage the UpdateProgress' "AssociatedUpdatePanelID" value in two separate places (i.e. in the custom control and in the web form).

Has anyone successfully done that, or is this going to be "fixed" in future releases?

Any help will be appreciated,
- K.

You need to expose the Update() event of the updatepanel and explicitly call it in response to whatever events are necessary.

Thanks DisturbedBuddha! I think this is what I am looking for.
