title: How to start my BusyIndicator from code behind
body: <p>I have this User control: I added this user control to my Winforms application (simple BusyIndicator):</p>
  
  <pre><code>&lt;UserControl x:Class="MyApp.UserControl1"             
               xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
           xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
           xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
           xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
           xmlns:xctk="clr-namespace:Xceed.Wpf.Toolkit;assembly=Xceed.Wpf.Toolkit"
           mc:Ignorable="d" 
           d:DesignHeight="300" d:DesignWidth="300"&gt;
      &lt;Grid&gt;
          &lt;xctk:BusyIndicator x:Name="busyIndicator" IsBusy="{Binding IsBusy}"  /&gt;
      &lt;/Grid&gt;
  &lt;/UserControl&gt;
  
  
  
     public partial class UserControl1 : UserControl
      {
          public UserControl1()
          {
              InitializeComponent();
          }
  
          public void SetIndicator(bool isBusy)
          {
              busyIndicator.IsBusy = isBusy;
          }
      }
  </code></pre>
  
  <p>Now from my main form i try to start my <code>BusyIndocator</code>:</p>
  
  <pre><code>UserControl1 uc = new UserControl1();
  uc.SetIndicator(true);
  </code></pre>
  
  <p>Also if i am changing <code>IsBusy="{Binding IsBusy}"</code> into <code>IsBusy="true</code> i can see my BusyIndicator but then i cannot stop it.</p>
  
  <p>But nothing happening, what i am doing wrong ?</p>
