How to access x:Name-property in code?

Question

I assigned x:Name in my XAML-file to a object which can trigger a MouseDown-event. In that event I'd like to get the x:name-attribute of the sender again. How do I do that?

The object looks like that:

<ModelUIElement3D MouseDown="ModelUIElement3D_MouseDown" x:Name="trololo">

If I have understood your question correctly, you can access the Name property by casting the sender to a FrameworkElement.

Alternatively you can just use the reference object that is created by the designer, the instance name is the same as the name that you specify in the x:Name attribute.

The following demonstrates both options.

  private void ModelUIElement3D_MouseDown(object sender, MouseButtonEventArgs e)
  {
    var element = sender as FrameworkElement;

    if (element != null)
    {
      if (element.Name == "trololo")
      {
      }
    }

    // Or

    if (sender == trololo)
    {
    }

  }
