Question

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):
alt text http://lh3.ggpht.com/_1TPOP7DzY1E/S0R1ORVt-pI/AAAAAAAAC3Y/UkS2zEMWa9o/s800/Capture4.png

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)?

Answer 1

1. Add a new panel control to your form (somewhere out of the way) and resize it to 0,0
2. Do NOT set Visible = false on this panel.

3. In your form add a standard MouseClick event handler as follows:

   private void Form1_MouseClick(object sender, MouseEventArgs e)
   {
       // Uncomment if in scrollable control
       //Point scrollPos = new Point(this.AutoScrollPosition.X, -this.AutoScrollPosition.Y);
       newPanel.Select(); 
       // Uncomment if in scrollable control
       //this.AutoScrollPosition = scrollPos;
   
   }
   

4. Now, when you click anywhere on your main form, any input control will lose focus and you will be able to handle the usual Validating events etc.
