Hi,
I have a RadGrid using the NeedDataSource event. The problem is that when I enter in EditMode, the entire grid is rebinded and I don't want to keep data in ViewState or Session variable, so on each edit/cancel edit the grid is rebinded.
I am keeping my primary key in the DataKeyValues, so is it possible to not rebind the grid on edit so I can create my own Object by passing the primary key.
I could use a NestedViewTemplate that have a UserControl that I can pass the primary key value and then I could manually bind this usercontrol with a custom object.
But the NestedViewTemplate also rebind the grid on ExpandColumn.
Any solutions?

Hello,
The grid requires to be rebinded when entering/canceling edit mode, in the NeedDataSource event you decide how to retrieve the data for the control, you can make a query to a database or store information in a session variable but you have to pass the data in the NeedDataSource event so the grid can properly create its data items. The information about the data items of the controls is not persisted in ViewState or anywhere else that's why the control requires rebind after postback to recreate its items as expected.
