title: Why is my Visibility binding not working?
body: <p>I have a problem with one of my Visibility Bindings.
  In my application I have a Textbox and a combobox at nearly the same place.
  They are overlapping so I have two Variables in the background for their Visibility. They are in a Datagrid, so the Visibility Source will be provided from the list.</p>
  
  <p>The Binding of my Combobox works absolutely fine, but the one of my Textbox doesn't</p>
  
  <p>Here is my Code:</p>
  
  <pre><code>&lt;TextBox    x:Name="Textvalue" 
              HorizontalAlignment="Left" 
              VerticalAlignment="Center" 
              Width="150" 
              BorderBrush="#FF383F55" 
              BorderThickness="0" 
              Foreground="White" 
              Background="#FF232734"
              Text="{Binding Path=Value, UpdateSourceTrigger=PropertyChanged}"
              Visibility="{Binding Path=IsPath}"/&gt;
  
  &lt;ComboBox   x:Name="Combobox" 
              VerticalAlignment="Center" 
              Foreground="White" 
              Margin="3,3,3,3" 
              Height="23"
              ItemsSource="{Binding Path=ValueArray}" 
              SelectedValue="{Binding Path=Value, UpdateSourceTrigger=PropertyChanged}" 
              Style="{DynamicResource ComboBoxStyle1}" 
              Visibility="{Binding Path=IsCombobox}"/&gt;
  </code></pre>
  
  <p>These are my Get Property for both (Both only have the Get Proberty):</p>
  
  <pre><code>public System.Windows.Visibility isPath
  {
      get
      {
          return _IsPath;
      }
  }
  
  public System.Windows.Visibility IsCombobox
  {
      get
      {
          return _IsCombobox;
      }
  }
  </code></pre>
  
  <p>I hope you can help me because I don't know what's wrong here :/
  Thanks in advance</p>
