I've been struggling with this issue for a few hours now where I wonder if there's a limitation or maybe it simply can't be done.
Is it possible to bind the Windows.Visibility property to the view model? My binding path is fine since I have other items bound, plus I've been able to bind the Windows.Background to the view model property.... just not the Visibility property. When I set the binding, nothing happens. It won't even hit the break point in the get property. Here's my code:
In the View XAML:

<Window.Visibility>
<Binding Path="IsVisible" Converter="{StaticResource MyConverter}"/>
</Window.Visibility>

In the view model:
public bool IsVisible {
get { return _isVisible; }
set {
if (this._isVisible != value) {
this._isVisible = value;
OnPropertyChanged("IsVisible");
}
}
}

My break point doesn't hit the Converter class either when I use the Visibility property. I've tested it other bindings in the same View and it works fine. Thanks in advance for any pointers...

Hi sisnaz,

Please try to set Mode property to "TwoWay" like the following:

<Binding Path="IsVisible" Converter="{StaticResource con}" Mode="TwoWay"/>

Let me know if it helps.


Best regards,

Visibility is not a boolean value. Does your converter accept the boolean value from the model and then converts it to aVisibilityvalue?

Thanks for the response. Yes, I've tried both the converter for the boolean to Visibility and simply using a Visibility property instead of boolean. The issue right now is .net completely ignores the binding at runtime. No errors or anything. The DataContext is fine, as I said, I can bind the background and controls... just not the Windows.Visibility.

Actually, binding erros are listed in the output window. Are you seeing any?

No binding errors in the output window either... I'm stumped.
I set a button with a click event to set this.Visibility = Visibility.Hidden; This works during runtime, but it's the view, not the view model.

That's odd, does the 'get' of the property get fired during runtime?

No, does not hit the get property :-(

"It won't even hit the break point in the get property."

Converters are a good way to debug bindings. Since you already have a converter, try putting a breakpoint on the first line of its Convert() function and see if that gets called.

Thanks Bruce! That did the trick... I really appreciate it.
