I am adding custom toolbars to Diagram control and want to arrange them in a single rather than two row.

Here is code for adding toolBars:

private void CreateToolbar()
{
NControlHelper.BeginUpdate(commandBarManager.ParentControl);
toolBarBuilder = commandBarManager.ToolbarsBuilder;
diagramCommander = commandBarManager.Commander;

NDockingToolbar originalToolStrip = commandBarManager.Toolbars[4];
//Assigning Action tools
NDockingToolbar layoutToolStrip = commandBarManager.Toolbars[6];

commandBarManager.Toolbars.Clear();

Nevron.UI.WinForm.Controls.NCommand command;

NDockingToolbar toolbar = new NDockingToolbar(commandBarManager);
//Adding only required tools from originalToolStrip and layoutToolStrip
toolbar.Commands.Add(originalToolStrip.Commands[1]);
toolbar.Commands.Add(originalToolStrip.Commands[14]);
toolbar.Commands.Add(layoutToolStrip.Commands[1]);
toolbar.Commands.Add(layoutToolStrip.Commands[2]);
command = new NCommand(new NCommandProperties() { Text = "MY Custom Button",
ID = toolbar.Commands.Count + 1, Designable = true, Name= "Custom Text",
Style = CommandStyle.Text });


NDockingToolbar toolbar1 = new NDockingToolbar(commandBarManager);
toolbar1.Commands.Add(command);
commandBarManager.Toolbars.Add(toolbar);
commandBarManager.Toolbars.Add(toolbar1);
}

Then how can i put them in single row or another type of toolbar class should be used??
