BUG: Cannot Set the Selected Item for a List box in Form Init (161730)

The information in this article applies to:

Microsoft Visual FoxPro for Windows 5.0
Microsoft Visual FoxPro for Windows 5.0a
Microsoft Visual FoxPro for Windows 6.0

This article was previously published under Q161730

SYMPTOMS

In Visual FoxPro 3.0 the selected item in a list box can be initialized by placing the following code in the Form Init or the List box Init:

   THISFORM.List1.Selected(1) = .T.

This does not work in Visual FoxPro version 5.0.

RESOLUTION

Place the following code in the Activate method of the form. The variable acts like a switch so that the code is executed only when the form is first instantiated. The variable switch should be added to the form as a property. Switch is initialized to false.

   IF !THISFORM.switch
     THISFORM.List1.Selected(1)= .T.
     THISFORM.switch = .T.
   ENDIF

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Behavior

Create a form and add the employee table to the DataEnvironment.
Add a list box to the form and set its RowSourceType to 6-Fields. Set its RowSource to employee.emp_id.
Place the following code in the Init of the form or the Init of the list box.
```
      THISFORM.List1.Selected(1)= .T.
						
```

Note that when the form is run, the first item is not selected.
