ArcGIS.Desktop.Layouts Namespace : LayoutFactory Class
Provides methods to create new layout project items.
Object Model

Syntax
public class LayoutFactory : ILayoutFactory  
Public Class LayoutFactory 
   Implements ILayoutFactory 
Remarks

Creating a new layout simply generates a new layout project item that appears in the Layouts folder in the Contents pane. The next logical steps are to create new layout elements. Refer to the LayoutElementFactory to add new elements to layout.

A new layout project item is not automatically opened in a layout view pane. Use methods in the LayoutFrameworkExtender to open a layout project item in a pane.

Example
//This example creates a new layout using a minimum set of parameters.

using ArcGIS.Desktop.Layouts;                    
using ArcGIS.Desktop.Framework.Threading.Tasks; 
using ArcGIS.Desktop.Core;

public class CreateLayoutEx1
{
  async public static Task<Layout> CreateBasicLayout(double width, double height, LinearUnit units, string LayoutName)
  {
    Layout layout = null;
    await QueuedTask.Run(() =>
    {
      layout = LayoutFactory.Instance.CreateLayout(width, height, units);
      layout.SetName(LayoutName);
    });

    //Open the layout in a pane
    await ProApp.Panes.CreateLayoutPaneAsync(layout);

    return layout;
  }
}
//This example creates a new layout using a CIM page definion with rulers and guides included.
