Hello all, I Added a New Ultragrid and binded it to the UD07View , I can Insert Update and Save the Records , but whenever i click Delete Toolbar , it prompts me the Error(Object Reference Error) , Appreciate your comments.
Have you ever used the Customization Wizards to add a UD table as a child table to another? That generates a grid and methods to use it, for add, update and delete. The delete is much more complex than the other two. I’d want to try doing that instead of coding everything myself. (I’ve used that wizard MANY times 
) You could do that in a customization you don’t intend to use and copy the delete code if nothing else.
@MLamkin Hello appreciate your comments , yeah actually I created the child table using Customization Wizards , however when I try to Delete the Grid Lines it Prompts me error .
