How to avoid color changes when button is disabled?

Question

We have a Windows Forms project with quite a few FlatStyle buttons.

When we disable the buttons, the colors of the buttons are changed automatically Frown | :(

Is it possible to override this somehow, so we can control the colors ourselves?

Answer 1

You need to use the EnabledChanged event to set the desired color. Here is an example.

private void Button1_EnabledChanged(object sender, System.EventArgs e)
{
    Button1.ForeColor = sender.enabled == false ? Color.Blue : Color.Red;
    Button1.BackColor = Color.AliceBlue;
}

Use the desired colors according to your requirement.

Also you need to use the paint event.

private void Button1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
    dynamic btn = (Button)sender;
    dynamic drawBrush = new SolidBrush(btn.ForeColor);
    dynamic sf = new StringFormat {
        Alignment = StringAlignment.Center,
        LineAlignment = StringAlignment.Center
    };
    Button1.Text = string.Empty;
    e.Graphics.DrawString("Button1", btn.Font, drawBrush, e.ClipRectangle, sf);
    drawBrush.Dispose();
    sf.Dispose();
}
