Maybe it doesn't sound very likely, but there must be a way to do this.
GridA is a list of all the purchase orders.
GridB is a list of the ordered items included in the selected order of GridA.
An edit form (WebUserControl) of GridB opens the details of the selected item of GridB.
Besides the normal Update/Cancel buttons inside the edit form, there is also a custom button, which creates a new order with the remaining quantity (not received yet) of this specific ordered item. After the custom button click does all the necessary steps, it closes the edit form with <editedItem.OwnerTableView.ClearEditItems()>
When the edit form is closed, a sub in the main aspx page must be executed, which updates the main grid (GridA) and selects the order which was just created. The selection, triggers the SelectedIndexChanged sub which, as stated above, binds the GridB to the items ordered by this new order.
So, how possible is it to use the RadAjaxManager to trigger this sub, when the edit form is closed?
If not possible, is there another approach to get this behaviour?
In this same edit form, the regular update/cancel buttons also exist and they work fine.
