How do I control the visibility of GridLines in GridGroupingControl?

The visibility of the lines in the Grid can be controlled by setting the GridLines property. The default setting is Both and other possible settings are: None, Horizontal, and Vertical.

C#

this.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Horizontal;

this.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Vertical;

this.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Both;

VB

Me.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Horizontal

Me.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Vertical

Me.GridGroupingControl1.GridLines = System.Web.UI.WebControls.GridLines.Both
