Ajaxified Dynamic RadGrid GirdEditCommandColumn never fires Update or Cancel command

[Owen]

I have grids populating a RadPanelBar that are created entirely from the codebehind using advanced data binding. I have a GridEditCommandColumn in this grid. When I click "Edit", ItemCommand is fired followed by EditCommand. At this time, the column displays "Update Cancel". Clicking either of these causes a postback, but ItemCommand does not fire. Nor does UpdateCommand or CancelCommand. As you can see in my .cs, I've attached every command handler I could find trying to find something triggered when I click Update or Cancel with no luck. Any help would be great.

Hi Owen,

I have noticed that you have set AllowAutomaticUpdates="true", when you are performing Manual CRUD Operations we don't set properties such as AllowAutomaticUpdates, AllowAutomaticInserts and AllowAutomaticDeletes. These are used when you have Automatic operations that don't use any UpdateCommand or InsertCommand events.
So please set it to false and see if it makes any difference.

Thanks,
Princy

Princy, thank you for your response. I have tried auto set to true, false, and default with no change. Basically, it seems that the href=" javascript: __doPostback..." is prevented from firing once "Edit" changes to "Update Cancel". If I override the raise Post Back, it never gets hit on the update event. It always gets hit on an edit or delete.

Hello Owen,

Could you please elaborate a bit more on the exact scenario you are implementing? Does the "PopulatePanelGrid" method called in Page_Init event? Note that declaring the RadGrid control this way it should be called exactly in Page_Init.
