Question

I am designing GUI for my project.
What I need to do is changing the color of a label depending on a boolean in a binding source. But the problem is that I need to assign a Color to the label wheres binding source doesn’t have this(I don’t want a Color property in binding source).

How can I handle to make label red when bool is true otherwise black?

Thanks in advance.

Answer 1

Since you cannot bind them directly, you have to create an extra property on either side. Either you add a Color property in the (business) object (which you said you didn’t want), so that leaves adding a property on the form/control which you bind to the property on your (business) object.

UPDATE

If you want to add a property to the form to which you can bind, add the following.

public bool MyPropertyToBindTo {
    get { return _myLabel.Color == Color.Red; }
    set { _myLabel.Color = value ? Color.Red : Color.Black; }
}

Now you can bind the business-object-property to this property, and it should work.
