FIX: Setting Grid RowHeight to Large Number Affects Page Down

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0

SYMPTOMS

When you set the RowHeight of a grid to a large number and you cannot see two complete rows in the grid, the PAGE DOWN key might not function properly. It might page down once and stop, or it might not page down at all. If the RowHeight is set to a number such as 150 or higher, then a general protection fault (GPF) might occur when you press the PAGE DOWN key one or more times while in the grid.

WORKAROUND

Make sure that there are at least two rows of data showing in the grid, or set the RowHeight property of the grid to a smaller number.

STATUS

This problem has been fixed in Visual FoxPro 5.0a.

MORE INFORMATION

The RowHeight of a grid must be set so that you can see at least two rows of data in the grid or else the PAGE DOWN key does not move through the records properly. The PAGE UP key and the ARROW keys work correctly, but PAGE DOWN key does not work. When the RowHeight is set less than 100, the PAGE DOWN key does not work. When the setting is more than 150, a general protection fault occurs when you press the PAGE DOWN key one or more times.

Steps to Reproduce Behavior

1. Create a form and add a table to the DataEnvironment.

2. Add a grid to the form and set the RowSource to the table in the DataEnvironment.

3. Change the RowHeight of the grid to 75.

4. Run the form and press the PAGE DOWN key. Note that it might page down once or not at all.

5. Modify the form and change the RowHeight of the grid to 200.

6. Run the form and press the PAGE DOWN key one or more times. A general protection fault occurs and Visual FoxPro closes.
