    Currently we use a grid in batch edit mode.  When we click save changes, then the controller's Update method is called passing it all the updated rows.  Then the controller's Create method is called, passing it all the added rows.  Then the controller's delete method is called, passing it all the deleted rows.
    Is it possible to, ( or if not, would you consider adding the feature) to configure the datasource to call a single "SaveAllChanges" controller method instead, which contains 3 parameters, one for the changed rows, one for the added rows and one for the deleted rows?
    This is to enable scenarios in which the collection of rows needs to have validation applied that takes all rows into account.  For example, the items in the collection may not exceed a certain total Qty.  So if a user deletes one row, and adds another row, the controller will execute the Create method first, and this could cause a failure of the validation because of a defined Max Qty for all rows being exceeded; meantime the removal of the deleted row will actually cause validation to pass, but the Create method of the controller cannot know that when processing its validation.
