Question

I am working on a DependencyProperty for my Avalon dock controller. Here is some sample code which i have currently working on.

Requirement is: Create all dependency properties in one single class and access the property in View. Something like this.

<Button isPaneVisible="true"> or <Button isPaneVisible="{Staticresource path=name, Mode=twoway">

Could you please help me to reslove this issue?

namespace Avatar.UI.ViewModel
{
    internal class DependencyPropertyClass : DependencyObject
    {
        public static readonly DependencyProperty IsPaneVisibleProperty =
            DependencyProperty.RegisterAttached("IsPaneVisible", typeof(bool), typeof(DependencyPropertyClass),
                new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, IsPaneVisible_PropertyChanged));

        private static void IsPaneVisible_PropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
        }

        /// <summary>
        /// Sets the IsPaneVisible for an element.
        /// </summary>
        public bool IsPaneVisible
        {
            get { return (bool)GetValue(IsPaneVisibleProperty); }
            set
            {
                SetValue(IsPaneVisibleProperty, value);
            }
        }

    }
}

<Button IsPaneVisible="true"></Button 

</UserControl>

Answer 1

The dependency property should derive the base calss for which you are going to create dependency property. for example, if you are going to create dependency property for button, then derive the base class button to your class.

This is how I have resolved my issue.
