title: Dynamically add Children to WPF UserControl and Handle its events from WinForm
body: <p>I have a Simple WPF userControl called "xNavPanel" Contains a panel.
  I added this control into Winform using "ElementHost".
  I have Another WPF UserControl called "MainMenuButton" contains textblock.</p>
  
  <p>From Winform; I add many "MainMenuButton" in "xNavPanel" Dynamically in runtime.
  I have method which do loop over DataTable rows
  and foreach row adding "MainMenuButton" into "xNavPanel"
  And Add an event handler to each "MainMenuButton".</p>
  
  <p>The Problem is; Controls doesn't invoke the handlers!</p>
  
  <pre><code>public static void FillMenu(xNavPanel navPanel, DataTable Items)
  {
      navPanel.MainPanel.Children.Clear(); //MainPanel is Panel inside UserControl
  
      MainMenuButton menuItem;
      foreach (DataRow dr in Items.Rows)
      {
          menuItem = SetMenuItem(dr);
          navPanel.MainPanel.Children.Add(menuItem);
      }
  }
  static MainMenuButton SetMenuItem(DataRow dr)
  {
      MainMenuButton menuItem = new MainMenuButton();
      menuItem.Name = "MI_" + dr["FormName"].ToString();
      menuItem.MenuName.Text = dr["Name"].ToString(); //MenuName is TxBlock inside UserControl
  
      menuItem.MouseUp += new System.Windows.Input.MouseButtonEventHandler(menuItem_MouseUp);
      //menuItem.MouseUp += ((sender, e) =&gt; MessageBox.Show((sender as MainMenuButton).Name));
  
      return menuItem;
  }
  static void menuItem_MouseUp(object sender, System.Windows.Input.MouseButtonEventArgs e)
  {
      MessageBox.Show((sender as MainMenuButton).Name);
  }
  </code></pre>
