PRB: Class Based on Grid Does Not Maintain FontBold Property

• Microsoft Visual FoxPro for Windows, version 5.0

SYMPTOMS

If a grid class has the FontBold property set to True (.T.), changing the ColumnCount of a grid class on a form causes the grid's columns, headers, and textboxes to lose their FontBold property settings. The grid object itself maintains its proper FontBold property value; however, the objects contained in the grid do not inherit this property value. These objects revert to the default value (False) for the FontBold property.

In Visual FoxPro 3.0b, changing the ColumnCount property does not affect the FontBold property of the grid's columns, headers, and text boxes. Therefore, you may notice this behavior on forms that are created in Visual FoxPro 3.0b and then executed in Visual FoxPro 5.0 for Windows.

RESOLUTION

In the Init of the grid class, add the following code:

      FOR i=1 TO This.ColumnCount
         This.Columns(i).FontBold=This.FontBold
         This.Columns(i).Header1.FontBold=This.FontBold
      ENDFOR

STATUS

Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The steps listed below assume a working knowledge of creating classes and forms and setting the properties of objects contained within a form.

Steps to Reproduce Behavior

1. Create a class based on a grid and name it zgridtest.

2. In this class, set the FontBold property to True (.T.).

3. Save the class.

4. Create a form called ztest.

5. Place a table in the data environment of the form.

6. Add the zgridtest class to the Form Control toolbar and add it to the form.

7. Run the form. The grid's textboxes and headers appear in a bold font.

8. Modify the form and select the zgridtest object in the Properties sheet.

9. Change the ColumnCount property to 2.

10. Run the form and note that the grid's textboxes and headers now appear in normal font.

11. Modify the form and select the zgridtest object. Choose the grid's column, header, or textbox objects. Note that the FontBold property of each of these objects is now set to False instead of True.
