FIX: Error Message "Variable is Not Found" When Running Form

MORE INFORMATION

This behavior occurs because the grid columns have a ControlSource set to a field that cannot be found because the table has not been opened.

Steps to Reproduce Problem

1. Create a new form.
2. Add the Customer table from the \VFP\Samples\Data directory to the DataEnvironment of the form.
3. Drag the Cursor object from the DataEnvironment and drop it on the form to create a grid.
4. Set the following properties for the grid:

   Grid1.ColumnCount = 2
   Grid1.Column1.ControlSource = Cust_id
   Grid1.Column2.ControlSource = Company

5. Save and run the form. Note that the grid has information in it. Close the form and modify it.
6. Open the DataEnvironment, and delete the Cursor1 object. Save and run the form.
7. The error "Variable Is Not Found" is displayed.
8. Click OK, and the form is displayed but the grid is empty.

NOTE: If you close the form and run it again, you do not see the error message, but the grid is still empty. Running the form after exiting and restarting Visual FoxPro causes the error message to be displayed.
