SplitContainer.Panel VS keyDown(Enter)

[KalupaPaluku]

Hello!!! I've got a problem of my form application that the KeyDown function doesn't work. It suppose to be go to the next textbox field within same panel control but it doesn't work, as i'm using SplitContainer.Panel in such forms. Isn't it the SplitContainer caused this problem happen? How can i solve the problem? The code that i'm use is VB 2005.

Private Sub TextBox64_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox64.KeyDown
If e.KeyCode = Keys.Enter Then
e.Handled = True
Me.ProcessTabKey(Not e.Shift)
TextBox64.Text = Format(Double.Parse(TextBox64.Text), "###,###,##0.00")
end if
End Sub
