copied!<p>Advantages of Dependency Property </p> <p>As a matter of fact a Dependency Property have a lots of advantages over the normal CLR properties. </p> <ol> <li><strong>Property Value Inheritance :</strong> By Property Value Inheritance we mean that value of a Dependency property can be overridden in the hierarchy in such a way that the value with highest precedence will be set ultimately. </li> <li><strong>Data Validation :</strong> We can impose Data Validation to be triggered automatically whenever the property value is modified. </li> <li><strong>Participation in Animation :</strong> Dependency property can animate. WPF animation has lots of capabilities to change value at an interval. Defining a dependency property, you can eventually support Animation for that property. </li> <li><strong>Participation in Styles :</strong> Styles are elements that defines the control. We can use Style Setters on Dependency property. </li> <li><strong>Participation in Templates :</strong> Templates are elements that defines the overall structure of the element. By defining Dependency property, we can use it in templates. </li> <li><strong>DataBinding :</strong> As each of the Dependency property itself invokes <code>INotifyPropertyChanged</code> whenever the value of the property is modified, <code>DataBinding</code> is supported internally. To read more about <code>INotifyPropertyChanged</code>, please read. </li> <li><strong>CallBacks :</strong> You can have callbacks to a dependency property, so that whenever a property is changed, a callback is raised. </li> <li><strong>Resources:</strong> A Dependency property can take a Resource. So in XAML, you can define a Resource for the definition of a Dependency property. </li> <li><strong>Metadata overrides :</strong> You can define certain behavior of a dependency property using PropertyMetaData. Thus overriding a metadata form a derived property will not require you to redefine or reimplementing the whole property definition. </li> <li><strong>Designer Support :</strong> A dependency property gets support from Visual Studio Designer. You can see all the dependency properties of a control listed in the Property Window of the Designer. </li> </ol> <p>In these, some of the features are only supported by Dependency Property. <code>Animation</code>, <code>Styles</code>, <code>Templates</code>, Property value Inheritance etc could only be participated using Dependency property. If you use CLR property instead in such cases, the compiler will generate error. </p> <p>please go through these articles,</p> <p><a href="http://www.codeproject.com/KB/WPF/BeginWPF4.aspx#diff" rel="noreferrer">http://www.codeproject.com/KB/WPF/BeginWPF4.aspx#diff</a></p> <p>and <a href="http://www.dotnetfunda.com/articles/article961-wpf-tutorial--dependency-property-.aspx" rel="noreferrer">http://www.dotnetfunda.com/articles/article961-wpf-tutorial--dependency-property-.aspx</a></p> <p>and <a href="http://msdn.microsoft.com/en-us/library/cc221408(VS.95).aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/cc221408(VS.95).aspx</a></p>
