Hello Amit Prajapati,
If you want to remove the Header part from all your RadTileViewItems you'll have to edit their default template and set the new style as an ItemContainerStyle to the RadTileView.
I've attached a sample project which demonstrates this, so could you please examine it and if you have more questions feel free to ask.
Kind regards,
Zarko
