Examples

The following code example demonstrates how to use the NotifyParentPropertyAttribute and the ExpandableObjectConverter class to create an expandable property on a custom control.

C#

[TypeConverter(typeof(BorderAppearanceConverter))]
public class BorderAppearance
{
    private int borderSizeValue = 1;
    private Color borderColorValue = Color.Empty;

    [Browsable(true),
    NotifyParentProperty(true),
    EditorBrowsable(EditorBrowsableState.Always),
    DefaultValue(1)]
    public int BorderSize
    {
        get
        {
            return borderSizeValue;
        }
        set
        {
            if (value < 0)
            {
                throw new ArgumentOutOfRangeException(
                    "BorderSize",
                    value,
                    "must be >= 0");
            }

            if (borderSizeValue != value)
            {
                borderSizeValue = value;
            }
        }
    }

    [Browsable(true)]
    [NotifyParentProperty(true)]
    [EditorBrowsable(EditorBrowsableState.Always)]
    [DefaultValue(typeof(Color), "")]
    public Color BorderColor
    {
        get
        {
            return borderColorValue;
        }
        set
        {
            if (value.Equals(Color.Transparent))
            {
                throw new NotSupportedException("Transparent colors are not supported.");
            }

            if (borderColorValue != value)
            {
                borderColorValue = value;
            }
        }
    }
}
