Question

I have one DataTable Which I gets from the BackEnd. But When I fix the BreakPoint and Visualize the DataTable, It does not show the NULL values. Why is it so?

In the BackEnd, My Table looks like below:

          CustID          JobID          Qty
        ----------       --------       ------
           1               NULL          100
           2                1            200

But in the FrontEnd, My DataTable looks like below:

           CustID          JobID          Qty
        ----------       --------       ------
           1                             100
           2                1            200

Why it is not showing the NULL Values? Is there any specific reason? How to show the DataTable as it is like in the BackEnd?

Answer 1

There is a difference between null in Database and null in code, To refer or check for nulls arising from data from a Database we have DBNUll and its not the same as null
