I have a simple situation (.NET2): a texbox1 on a UserControl1(or Form1).

I want to unfocus(leave) the texbox when I click on the usercontrol/form(focus the usercontrol/form instead):

I do the following on the UC/form:

      Protected Overrides Sub OnMouseClick _
          (ByVal e As System.Windows.Forms.MouseEventArgs)
        MyBase.OnMouseClick(e)
        Me.Focus()
      End Sub

Why does it not work on the child textbox, but works very well on the non-child one(focus on textBox2 then click on the panel removes the focus from the textBox2)?
