BUG: Disabled Listbox Items Enabled Using Arrow Keys

• Microsoft Visual FoxPro for Windows, version 5.0, 5.0a
• Pro Edition of Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b

SYMPTOMS

An item in a ListBox control can be disabled by placing a backslash (\) before the item. The item will be grayed out and cannot be selected by using the mouse.

WORKAROUND

You can select the disabled item using the keyboard arrow keys, and the Value and ControlSource properties of the list box will reflect the value of the selected disabled item.

Steps to Reproduce Behavior

1. Create a new form.

2. Add an array property to the form and name it aListItems1[9].

3. In the Load event of the form, add the following code:

   DIMENSION ThisForm.aListItems1[9] ThisForm.aListItems1[1]="First" ThisForm.aListItems1[2]="Second" ThisForm.aListItems1[3]="\Third" ThisForm.aListItems1[4]="Fourth" ThisForm.aListItems1[5]="Fifth" ThisForm.aListItems1[6]="Sixth" ThisForm.aListItems1[7]="Seventh" ThisForm.aListItems1[8]="\Eighth" ThisForm.aListItems1[9]="Ninth"

4. Add a TextBox to the form.

5. Add a ListBox to the form, and set the properties as follows:

   ControlSource = ThisForm.Text1.Value RowSourceType = 5 - Array RowSource = ThisForm.aListItems1

6. Save and run the form.

7. Using the keyboard arrows to move up and down in the ListBox, try to select the disabled items. Note that the disabled item gets selected and the value is displayed in the TextBox.
