I have the following property in my usercontrol:

[Category("Appearance")]
[Description("The color of the liquid that is inside the thermometer.")]
[DefaultValue(typeof(Color),"Red")]
[RefreshProperties(RefreshProperties.Repaint)]
public Color LiqidColor
{
  get
  {
    return this.liquidColor;
  }
  set
  {
    this.liquidColor = value;
  }
}

Now I have two issues with this.
1. If I right-click in the property sheet and select reset the color returns to Red which is great but when I rebuild the color is all of a sudden gone. What is up with that? I have gotten around this by setting the value of the private member (liquidColor) in this example to equal the default color in the constructor of the class.

2. What is supposed to happend when I change the color in the designer's property sheet? Shouldn't the color change? (I use this color in the OnPaint event. What exactly does RefreshProperties(RefreshProperties.Repaint) do for me?

Thanks,
Einar
