FIX: Grid is Empty with Incorrect Column ControlSource (168043)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0
  • Microsoft Visual FoxPro for Windows 5.0a
This article was previously published under Q168043

SYMPTOMS

Specifying an invalid column ControlSource name in a Grid results in an empty grid in Visual FoxPro 5.x. However, in Visual FoxPro 3.x, this results in the following error, which is expected:
"Error loading File - ControlSource..., Variable "column name" is not found"

RESOLUTION

Check the ControlSource names in each column and make sure they are valid names.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This has been corrected in Visual FoxPro 6.0.
