Hello Mypost,

In the linked sample from your post, the WHDG is using AutoCRUD, therefore the save button's function is only to initiate a postback, and all the batched CRUD operations are handled automatically by the grid. A list of the datasources which support AutoCRUD may be seen at:

http://help.infragistics.com/doc/ASPNET/2013.2/CLR4.0/?page=WebDataGrid_Supported_Data_Sources.html

Should Manual CRUD be required in this scenario, an example illustrating how the different CRUD operations of the grid may be handled can be found at:

Please feel free to contact me if you have any questions.
