An
UpdateProgress
control is supposed to be used with an
UpdatePanel
. In your code sample, I don't see an
UpdatePanel
. Check out the following tutorial:

If you just have 1 update panel, you can also add a update progress control. So when a partial post-back occurs w/in the update panel, the update progress control will be initialized and disabled when the partial update is complete.
But, in case you have multiple update progress controls you also have to specify a
AssociatedUpdatePanelID
.
The tutorial discusses all of this in detail. Check it out!
