How to change the ForeColor of a disabled button-CodePudding

So I have this button that launches another program. I disable it after launch to prevent double launch situations. Problem is the ForeColor changes from white to black which doesnt look good against my dark BackColor. How do I make the ForeColor not change when disabling or even change it after disable?

You need to use EnabledChanged and paint events of the current button. Suppose your button name is button1.

    private void button1_EnabledChanged(object sender, EventArgs e)
    {
        Button currentButton = (Button)sender;
        button1.ForeColor =  currentButton.Enabled== false ? Color.White : currentButton.ForeColor ;
        button1.BackColor = currentButton.Enabled == false? Color.Black : currentButton.BackColor;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        button1.Enabled = false;
    }

    private void button1_Paint(object sender, PaintEventArgs e)
    {
        Button btn = (Button)sender;
        var solidBrush = new SolidBrush(btn.ForeColor);
        var stringFormat = new StringFormat
        {
            Alignment = StringAlignment.Center,
            LineAlignment = StringAlignment.Center
        };
       
        e.Graphics.DrawString(button1.Text, btn.Font, solidBrush, e.ClipRectangle, stringFormat);
        solidBrush.Dispose();
        stringFormat.Dispose();
    }

You can add some css to target that element when it is in disabled mode, for example:

.my-button:disabled {
    // Apply styling here
}
