Hi Paolo,

Let me make a quick clarification first. If you use a Button in the content of the RadTileViewItem a drag operation can not be started from it because all buttons are handling the MouseDown event. However, the inner logic of the RadTileView control allows you to start a drag operation only inside the Header of the TileViewItem. Starting a drag operation inside the content can be implemented by replacing the default style of the control with a custom one. You can read more information about changing the template of a control in our Help documentation
