I posted this message to another board and have hardly had any views on it,
leave alone answers. So I am cross-posting here.
This may be a very simple question but I can't get my head around it.
I have a textbox's enabled property bound to the IsNew property of an object.
this.txtPhone1. DataBindings.Ad d("Enabled", this.BindingSou rce, "IsNew", true);
So when the IsNew property is true, my textbox is enabled. This is correct
behavior.
However, I want to reverse this behavior. In other words, I'd like to bind
the enabled property to !IsNew, so that the textbox is disabled, when the
IsNew property is true. How can I do this without creating a new property on
the object that returns !IsNew??
Thanks,

Naveen,
I assume that the IsNew property has 2 stati.
True and false.
Therefore your binding says when it is false.
("Enabled", this.BindingSou rce, Property , true);
Textbox.Enabled = false;
The IsNew in your binding is only an address, it has no sense to set that
negative.

Cor,
Thanks for your reply. I'm not sure I fully understand your reply.Let me
explain in a little detail.
1) A textbox is bound to an object.
2) The object has an IsNew property.
private bool _isNew = false;
public bool IsNew
{
get{return _isNew;}
set{_isNew = value}
}
3) I need to bind the enabled property of a textbox to the negative of the
value of IsNew. i.e. if IsNew = true, I want the textbox.Enabled = false and
if IsNew = false, I want textbox.Enabked = true.
Obviously I would like to do this in 1 databinding statement, without any if
statements. This enables me to set the databinding and forget about it,
because I'll have the DataSourceUpdat eMode to OnPropertyChang ed.
So this statement,
this.txtPhone1. DataBindings.Ad d("Enabled", this.BindingSou rce, "IsNew",
true, DataSourceUpdat eMode.OnPropert yChanged);
does the exact reverse of what I need. It sets txtPhone1.Enabl ed = true if
IsNew = true and vice-versa.
I guess my question is, is there a way to change this statement to set
txtPhone1.Enabl ed = true, if IsNew = false and vice-versa??
Thanks,

Add another property for IsNotNew and bind to that.
