Could you please explain what exactly do you mean by "Is it possible to trigger "tileView:TileViewCommands.ToggleTileState" command outside the toggle button " ? Do you want to trigger this command with another button or you want to change the tilestates by clicking on (for example) the content ?
You can set this command to any button that is inside a RadTileViewItem and it should work fine and with a little bit of code behind and some events you can toggle the tilestates with almost anything.
For further references could you please examine the attached project and if you have more questions please feel free to ask.
