How to force paint after setting Enabled = false in a C# windows usercontrol, not WPF?

Question

Hi,

How to force paint after setting Enabled = false in a C# windows usercontrol ?

Answer 1

If you're talking about WPF UserControls, you can just subscribe to the IsEnabledChanged event of your control and call InvalidateVisual() in the event handler.

Answer 2

If you are using winforms:

myControl.Invalidate();
myControl.Update();

Answer 3

Use EnabledChange event for the UserControl..

private void userControl_EnabledChanged(object sender, EventArgs e)
{
    if (! Enabled)
        Invalidate(); // ask the control to redraw itself
}

Note: put this code inside the userControl class, not in the form. Good luck!
