Hi,

I have a UserControl with a TextBox in it. TextBox has Validating event

handler that can cancel the validation. If I place two UserControls
like this on a form then Validating event will be firing twice. To
demostrate this I put the following code inside the UserControl.

       private int count = 0;
       private void textBox1_Validating(object sender, CancelEventArgs

e)
       {
           e.Cancel = true;
           textBox1.Text = (count++).ToString();
       }

I can see then the couter growing by 2 every time I try to change focus

from one user control to another.

The behavior is the same in VS.NET2003 and VS2005.

Can anybody explain why it's happening and what could be a fix or
workaround?

Thanks
