Question

I try to update the forecolor and text of a label in run time by invoke, The text changes but the forecolor does'nt. What could it be?

Code:

this.BeginInvoke(() =>

    lbl.Text="Home";
    lbl.ForeColor=Color.White;
}

I found the answer:
The label was of Metro Framework control, and I was needed to define lbl.UseCustomForeColor=True
