SYMPTOMS
You drag a field from a form's data environment to a grid you are editing and an error occurs that gives the following message:

Parent object will not allow this property setting for Formset1.Form1.Grid1.Column1.Text1.ControlSource.

-or-

This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor.

NOTE: the error wording is from Windows 95. In other versions of Windows, a general protection (GP) fault occurs with different wording.

The first error occurs if:


 * You drop the field on an exposed column in the grid and you are using Visual FoxPro version 3.0 for Windows.
 * You drop the field on any part of the grid and you are using Visual FoxPro version 3.0b for Windows.

The second error occurs if you drop the field on the area of the grid other than an exposed column and you are using Visual FoxPro version 3.0 for Windows.



STATUS
Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.



MORE INFORMATION
Drag and drop succeeds in placing the TextBox object into the exposed column but does not allow the ControlSource to be set.

Steps to Reproduce Problem

 * 1) Create a new form, and place a grid on the form from the Form Designer toolbar. Set the grid's ColumnCount property to 1.
 * 2) Right-click the form, and select Data Environment. Then right-click the Data Environment window, and select Add.
 * 3) Select a table and add it to the Data Environment.
 * 4) Right-click the grid, and select Edit.
 * 5) Drag a field from the table in the Data Environment, and drop it on the exposed column in the grid. At this point, the first error occurs. If you examine the Column in the Property Sheet Object list box, you may note the added text box is now present but the ControlSource property for that text box is not set.
 * 6) Drag a field from the table in the Data Environment, and drop it anywhere on the grid other than the exposed column. At this point, the second error (a GP fault) occurs in Visual FoxPro version 3.0 for Windows.
