I searched the list and the net and found a few vague references to my
question, but no concrete answers.
I have a control where I want to specify default values so the property
grid does not incorrectly bold the default settings (visual cue that they
have been changed from the default when this is in fact not true).
Say I have something along the lines of:
[Category("Appearance"),
Description("Gets or sets alternate background color."),
Browsable(true),
DefaultValue(SystemColors.Control)]
public Color AlternateBackColor
{
get {return alternateBackColor;}
set {alternateBackColor = value;}
}
The error I get, of course, is:
"An attribute argument must be a constant expression, typeof expression or
array creation expression"
So, how to make this a constant expression?
I have tried other things like DefaultValue(-2830136) (the RGB value I get
returned for SystemColors.Control), but neither this, nor any of the other
things I have tried has worked.
Does anyone know how to specify real default settings attributes for Color
and Font properties like this? Bool, int, string, etc are so easy, but
it's just not intuitive for any of these complex object types. I won't be
surprised if someone shows me it's really easy for Color, but Font looks
like it would be a bit more complex to represent in this attribute in some
way.
I would say the bold in the property grid is simply a cosmetic thing, but
it gives a completely false user cue and is unprofessional.
Any insight into this would be appreciated.
Thanks,
Jeff
