Problem using Repeater in UpdatePanel control. Does not update

[Guest]

I have a need to have a repeater inside update panel control which should
update dynamically when "Update" button is clicked. I have repeater inside
update panel control which takes custom collection as its datasource.
However, the panel doesn't update and refresh of page is required (not
asynchnonous).

Is it possible to have repeater to dynamically update with update panel
control?

Thanks
