I have a Label on a Windows.Form. I set the AutoSize property on the label to True and I noticed that when I do that, it pads the right hand side with ~5px of white backgrou
Ok, so FlastStyle = System; AutoSize = false; and then set up a property that will calculate the width like this:
public string LabelText
{
set
{
_label.Text = value;
using (Graphics g = CreateGraphics()) {
_label.Width = (int)g.MeasureString(_label.Text, _label.Font).Width;
}
}
}
There's no way when you use only padding and margin. That's the default behavior.

In the above Window I've set the Padding and Margin to [0,0,0,0]. Those 5 pixels are still there.
If you set FlatStyle = System and AutoSize = False you can get this:

In the above Window you don't have those 5 pixels anymore.
