When utilizing the context menu filtering it works fine for adding 1 filter. If you do another action, like sort or add another filter, it keeps the previous filter but doesn't show it in the menu. If you click "Clear Filter" it does clear the filter that you don't see and refreshes the grid as you would expect. It doesn't do this in the Telerik demo, so I'm thinking there's something wrong with my code or there's been a fix since the Telerik build we're using (2013.2.717.35). Any ideas? Thanks.
The behavior you are observing is seen because the ViewState for RadGrid is disabled.
In order to enable the filter TextBoxes to persist their values try setting the EnableViewState property for RadGrid to true.
