    text
    copied!<p>Im having a control named <strong><em>MyControl</em></strong> which contains a Collection&lt;<strong><em>MyClass</em></strong>> named <strong><em>MyClasses</em></strong> </p> <pre><code> &lt;MyControl&gt; &lt;MyClasses&gt; &lt;MyClasss Value={Binding} /&gt; &lt;/MyClasses&gt; &lt;/MyControl&gt; </code></pre> <p><strong><code>MyClass</code></strong> that is derived from <code>DependencyObject</code></p> <pre><code> Public Class MyClass : DependencyObject,INotifyPropertyChanged { Value //propdp (DependencyProperty) } </code></pre> <p>Im having a <code>DataTable</code>. I need to bind the data present in table[0][0] with the Value Property of <strong>MyClass</strong></p> <pre><code> Binding valuebinding = new Binding(); valuebinding.Path = new PropertyPath("ItemArray[0]"); valuebinding.Source = Table.Rows[0]; valuebinding.Mode = BindingMode.TwoWay; BindingOperations.SetBinding(myValue, MyClass.ValueProperty, valuebinding); BindingOperations.SetBinding(textBlock, TextBlock.TextProperty, valuebinding); </code></pre> <p>Now i need to dynamically change the value of the data present in the data table ? is there issue in it? whether the solution related to the below reasons?</p> <ol> <li>The DependencyObject class overrides and seals the Equals() and GetHashCode() methods</li> <li>DependencyObjects are not marked as serializable</li> <li>DependencyObject has thread affinity – it can only be accessed on the thread on which it was created</li> </ol> <p><strong>NOTE: It works fine in Silverlight</strong></p>
