I'm using the asp.net component.

I don't see a way to use javascript to change the grid filter, so I'm doing a manual $('#JQGrid1').trigger(“reloadGrid”);

I have a hidden input field that I'd like to include the filter string, but in the postback, it's not seeing the changed values, I'm assuming because the field is not within the JQGrid's custom form it doesn't get returned in the postback query.

Is there anyway, without doing a full page refresh with new data, to customize the grid postback call?
