Databinding Expressions?

[Chike J. Okor]

Is it possible to Databind to an expression? I have a collection of classes
and one of the properties returns a boolean value. I'm trying to databind
to the "inverse" of the boolean value as such

TextBox1.DataBi ndings.Add("Rea dOnly",customer s,"IsActive") ;

I need to bind this to the Inverse of IsActive (!IsActive) and not IsActive
itself ... it this possible?

Thanx

Hi Chike,

I beleive it will be easier to introduce an additional property called
IsNotActive :-)
However, if this is out of the question, you can probably make good use of
the Binding class' Format and Parse events to carry out the inverstion on
the fly.
