How to bind visibility property

Question

The XAML code is as follows:

<Helper:BooleanVisibilityValueConverter x:Key="BoolToVisible" />
   <Control x:Name="ResizeDecorator" MouseMove="ResizeDecorator_MouseMove" Template=" {StaticResource ResizeDecoratorTemplate}" Visibility="{Binding IsButtonVisible,Converter= {StaticResource ResourceKey=BoolToVisible},RelativeSource={RelativeSource  TemplatedParent}}" />
<Helper:BooleanVisibilityValueConverter x:Key="BoolToVisible" />
<Control x:Name="ResizeDecorator"  MouseMove="ResizeDecorator_MouseMove" Template="{StaticResource ResizeDecoratorTemplate}" Visibility="{Binding IsButtonVisible,Converter={StaticResource ResourceKey=BoolToVisible},RelativeSource={RelativeSource TemplatedParent}}"  />

The ViewModel code:

private bool _IsButtonVisible;
public bool IsButtonVisible
{
    get { return _IsButtonVisible; }
    set
    {
        _IsButtonVisible = value;
        NotifyPropertyChanged("IsButtonVisible");
    }
}

IsButtonVisible =false;

Can anyone tell me where am I going wrong?

Please edit the question. The sentence "How to visible/hidden visibilty property in wpf" doesn't make any sense. — Gurucharan Balakuntla Maheshku, May 07 '12 at 09:26
Check in the Output window, you may get some hints. Can you show the converter code? — Prashant Cholachagudda, May 07 '12 at 09:28
The Converter code is as follow:public class BooleanVisibilityValueConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value != null) { if (((bool)value) == true) return Visibility.Visible; else return Visibility.Collapsed; } return Visibility.Collapsed; } } — user1722947, May 07 '12 at 09:29
I'm guessing that the problem is that you are binding to IsButtonVisible on your templated parent. Instead you need to bind to IsButtonVisible on the ViewModel/DataContext of your templated parent - i.e. Visibility="{Binding DataContext.IsButtonVisible,Converter={StaticResource ResourceKey=BoolToVisible},RelativeSource={RelativeSource TemplatedParent}}". — Jakob Christensen, May 07 '12 at 09:46
