I’m trying to use the RadGrid in a Page with disabled ViewState.

<%@ Page Language="C#" AutoEventWireup="true" EnableViewState="false" … %>

Here’s my scenario:

·         My page contains a RadGrid with  EditMode="EditForms" and a  <rad:GridEditCommandColumn /> column.

·         When clicking on this column, the edition starts as it should.

·         On the next postback – might be not even due to a grid event – the grid “forgot” is has entered edit mode and the form is not displayed anymore.

I understand the behaviour since I’ve deactivated the ViewState. I’d like to maintain this information in the server in a custom way. My question is how do I hook the grid’s server-side events to tell it that it is in edit mode ?

I’ve found the following example on your community site:

http://www.telerik.com/community/code-library/submission/b311D-tgtkd.aspx

Although this example does not rely on the ViewState for the current data of the grid, it relies on the ViewState for the “edit” mode.

Thanks

• Can I use the standard one or do I need to purchase the MOSS version? 
• Does the MOSS version have any benefits? 
• Do I need to pay full licence price for the MOSS version if I already have a licence for the RadEditor?
