Telerik RadGrid - hide left-most column

Can't remember / driving me crazy - how to hide the upper-left-most cell/column of a Telerik WPF RadGrid (so all column headers are flush-left?) I know it's something ri开发者_StackOverflowdiculously easy/ simply forgot.

You can set RowIndicatorVisibility="Collapsed" to achieve this.

On RadGridView go to Open Property Builder Click on MasterTemplate on Left side and Uncheck the ShowRowHeaderColumn in settings tab.enter image description here
