How can I programmatically add a NavigatorBar to the GridGroupingControl?

You can programmatically add a NavigatorBar to the Grid using ButtonBars.Add method.

C#

//New NavigatorBar

NavigatorBar navBar = new NavigatorBar();

//Add the default buttons to the NavigatorBar

NavigatorBar.AddDefaultNavigatorBarButtons(navBar);

//Add the NavigatorBar to the Grid's ButtonBars Collection

this.GridGroupingControl1.ButtonBars.Add(navBar);

VB

'New NavigatorBar

Private navBar As NavigatorBar = New NavigatorBar()

'Add the default buttons to the NavigatorBar

NavigatorBar.AddDefaultNavigatorBarButtons(navBar)

'Add the NavigatorBar to the Grid's ButtonBars Collection

Me.GridGroupingControl1.ButtonBars.Add(navBar)
