Test for Object Visible

Hi How do you test for an object visibility in TC?

my mapped name:

Aliases.MyView_GUI.HwndSource_BinaryDialogView.BinaryDialogView.Grid.Viewbox.Grid.Border.Grid.TextblockReallyDeleteUserUsername

I assign the return value of the mapped name of above to a varaible as follows

var user = Aliases.MyView_GUI.HwndSource_BinaryDialogView.BinaryDialogView.Grid.Viewbox.Grid.Border.Grid.TextblockReallyDeleteUserUsername

then I test for Visible but it says can't find obejct and doesn't return anyhting

  if(user.Visible)
  {
    Log.Message("Visible");
  }
  else
  {
    Log.Message("Not Visible");
  }

why doesn't this work? TC gives me  "the object does not exist".... which it does and is active on the screen.

this should be easy what am I missing?

thanks
