The 'Specified method is not supported' and 'Updating is not supported by data source 'X' unless UpdateCommand is specified' errors occur

These errors may occur if you bind ASPxGridView to a custom data source at runtime and do not implement CRUD operations (such as INSERT, SELECT, UPDATE, and DELETE).

To resolve these errors, handle the following ASPxGridView events:

• The BatchUpdate event if the control is in batch edit mode.

• The RowInserting, RowUpdating, and RowDeleting events if the control is in any edit mode except batch.
