ErrorProvider.GetIconPadding Method (Control)
Returns the amount of extra space to leave next to the error icon.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Many icons typically have extra space around their central images, so the padding value is only necessary if additional space is necessary. Padding values can be positive or negative. Negative values cause the icon to overlap the edge of the control. The default icon padding is 0.
