I have a GridHyperLinkColumn in my RadGrid and I need to save the filter state across server requests (in a session) so that when the user returns to the page the grid is in the same state as it was left.  I have studied the code at

http://www.telerik.com/help/aspnet-ajax/grdsavingsettingsonperuserbasis.html 

and I see the comment to "call SaveSettings at Render."  I believe I want to call SaveSettings went the client request is fired by clicking on a hyperlink - how do I capture that event in the code-behind?

tia,
Mark

Never mind...looked up Rendering in my ASP 3.5 manual and figured it out...except for one snag:

I have a RadComboBox as a custom dropdown filter.  When an item is selected, the grid returns items matching the selection, but when additional filters are used, the custom filter returns to its NoFilter state.  Obviously, this is not good.

How do I persist the custom filter's state across server requests from other filters?

Hello Mark,

Can you please supply some additional information on your setup - how do you trigger the filtering?
The following example:

http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx

demonstrates custom filtering for the grid control - the value(s) for the dropdowns are preserved as expected. Let me know if this is the expected behavior, or if there are additional settings to keep in mind.
