title: Always show WPF TextBox Tooltip
body: <p>Is it possible to display tooltip constantly, not depending on whether the control is focused ot not, but depending only on the value of the bind property.</p>
  
  <pre><code>&lt;TextBox Name="projectTextBox" 
           ToolTipService.Placement="Bottom" ToolTipService.ShowDuration="12000" 
           MinWidth="150" Text="{Binding ProjectName}" IsEnabled="{Binding IsEnabled}"&gt;
      &lt;TextBox.ToolTip&gt;
          &lt;ToolTip Placement="Bottom" 
                   StaysOpen="True" Content="TEXT" 
                   Visibility="{Binding IsNotFound, Converter={StaticResource booleanToVisibilityCollapsedConverter}}" 
                   IsOpen="True"&gt;
          &lt;/ToolTip&gt;
      &lt;/TextBox.ToolTip&gt;
  &lt;/TextBox&gt;
