Nancy,

Actually, the reason I ask this question is probably for the same reason you wrote your example, i.e. I want to set the NullDisplay property of the textbox to not display anything if the datum is .NULL.

When I run this under the debugger, and set a breakpoint in the grid refresh method, and examine the columns collection, I can see that the NullDisplay property for Text1 is set to "", however, when the grid displays, the word .NULL. appears when the datum is .NULL.

Any thoughts on why I don't get a blank NULL display?

Thanks again,
Jim
