XAML Textbox Clearing When User Starts To Type

I have an XAML Textbox that kind of acts as it's own Label.

Like the Experts Exchange search box.  

Mine reads "Enter a search term"

Unlike the EE example, where the text clears on mouseenter, I'm using Windows Phone and programmatically set the focus to the textbox, so I need "Enter a search term" to disappear when the user starts to type.

I wrote this...

Private Sub tSearch_Keydown(sender As Object, e As KeyEventArgs)
        If tSearch.Text = "Enter a search term" Then
            tSearch.Text = e.Key.ToString
            tSearch.SelectionStart = 2
            tSearch.SelectionLength = 0
        End If
End Sub

Open in new window


... which works fine unless the search term happens to begin with a number.  I think it must be something to do with the keyboard switching key ?

Try moving your logic to the GotFocus event and automatically select all the current text.  Then when typing begins, it clears the value that is there.  

Private Sub tSearch_GotFocus(sender As Object, e As System.EventArgs) Handles tSearch.GotFocus
                tSearch.SelectAll
End Sub

I have tried selecting the current text before but in windows phone it displays the selection markers (changes colour and places little lines and circles)
