RadFilter and RadGrid entire page posts back

[Celeste]

Dear Forum,

Please assist! This is my first attempt at using RadFilter with RadGrid and it does work, but the entire page insists upon posting back and I cannot work out how to keep that from happening. I would like the page to work in exactly the same manner as the example
http://demos.telerik.com/aspnet-ajax/filter/examples/saveloadexpressions/defaultcs.aspx
My page does not seem to know that it should be using AJAX for a partial page postback and I don't get the page loading rotating circle image either. I have copied the entire example page and used my radgrid and data source in place of the example radgrid and data source, but still the entire page posts back. What is the deal? Any ideas?

Thanks,
Celeste

Dear Forum,

Please never mind! For some unknown reason, the page just started working properly now. I don't know why and I'm not all that concerned, maybe it just needed a timeout!

Thanks,
Celeste
