I present a large grid in a webpage and I wanted to disable the viewstate to make the page lighter, However, with a disabled viewstate my grouping is not kept when a postback occurs (when I drag another column header in the group panel for example).
Is there any way to keep the grouping functionality with a disabled viewstate? If so, how can it be done?
FYI : My grid's datasource is set dynamically (in the "NeedDataSource" event).

Hello Nicolas,
RadGrid does not persists its GroupByExpressions collection when ViewState is disabled as stated in the help article below.
In order to achieve your scenario you could save the GridTableView.GroupByExpressions collection in a Session variable and retrieve it on every Page_Load and save it in every Page_PreRender.
