PRB: ComboBox Text Property Does Not Update Properly

SYMPTOMS

The ComboBox Text property is not updated until after the ComboBox Click event is complete. This behavior may be a problem if the value of the Text property is required during the ComboBox Click event.

RESOLUTION

The ListIndex property is updated as soon as the item is selected and can be used to determine the text of that item. To work around this problem, use the ListIndex property as follows:

Combo1.List(Combo1.ListIndex)

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

Create a new Windows CE project in either Visual Basic or eMbedded Visual Basic. Form1 is created by default.
Add a ComboBox (Combo1) to Form1.

Add the following code:

      Option Explicit
      Dim x

      Private Sub Form_Load()
         For x = 1 to 8
            Combo1.AddItem "Item" & x
         Next
      End Sub

      Private Sub Combo1_Click()
         MsgBox "Text: " & Combo1.Text & ", ListIndex: " & _
         Combo1.ListIndex
      End Sub

Press F5 to run the project.
Click the drop-down arrow of Combo1 and click Item1. Note that the message box shows the value of the Text property as Combo1 instead of Item1.
