PRB: Can't Define Text Object ControlSource Property in a Grid

• Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

When attempting to change the ControlSource Property of the Text1 text object in a column of a grid, you receive this error message:

   Parent object will not allow this property setting Text1.ControlSource

CAUSE

This is by design. This occurs because when the column is bound, the ControlSource property is implicitly set.

RESOLUTION

Set the Bound property to false (.F.) for the column. If the column is not bound, you can set the ControlSource for Text1.

STATUS

This behavior is by design. It follows the principle of inheritance in Object Oriented Programming. The column is bound to a ControlSource already, so the Text1 object in the column is inheriting the same ControlSource property.

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a grid on a form.

2. Define a column. (You may need to specify a ColumnCount.)

3. Select Text1 in the Property Sheet's Object box.

4. Click the Data tab.

5. Select the ControlSource property.

6. Click the Expression box down arrow.
