Ajax Post/JQuery - Refresh WebGrid - Losing filtered dataset

Hi,

I am following Mike Brind's example to add records to a webgrid using an AJAX form post.

http://www.mikesdotnetting.com/Article/155/WebMatrix-And-jQuery-Forms

The only difference is that I am using dropdown box on the main form to display a filtered dataset in the webgrid.

When I add a record using the popup dialogue box and refresh my webgrid, I lose the filter on my webgrid and see all records.

I want to maintian my filtered webgrid after the webgrid is refreshed

Below is the RAZOR code and the jQuery/AJAX code.

Thanks

Geoff
