FIX: Setting Grid RowHeight to Large Number Affects Page Down

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.
