Refresh a control

Question

I am trying to change a link label's fore color but the color won't graphically change.

I have a timer that updates the fore color of the control

private void Timer_Tick(object sender, EventArgs e)
    {
        MyLbl.ForeColor = shouldUpdate? Color.Blue: Color.Gray;
    }

The update is successful and while debugging, I can see that the fore color property of myLbl is different. So why doesn't it change it graphically?

I also tried

MyLbl.ForeColor = Color.Gray;

And tried adding Application.DoEvents() after the change of the fore color.

Any solutions?
