Hi All,

I upgraded to version 12.12.17.12 recently and found the following code no longer compiles:

NPrintManager printManager = new NPrintManager(document);
printManager.PrintOnSinglePage = true;

I would be grateful for any help in getting this code to compile.

Thanks in advance

Hi,

This is a complete working sample that substitudes the print preview command.

using System;

using System.Windows.Forms;

using Nevron.Diagram;

using Nevron.Diagram.Extensions;

using Nevron.Diagram.WinForm;

using Nevron.Diagram.WinForm.Commands;

namespace WindowsFormsApplication15

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

NDrawingView view = new NDrawingView();

view.Dock = DockStyle.Fill;

Controls.Add(view);

view.Document = new NDrawingDocument();

NDiagramCommandBarsManager manager = new NDiagramCommandBarsManager();

manager.ParentControl = this;

manager.View = view;

MyPrintPreviewCommand.UpdateCmdBarManager(manager);

}

}

public class MyPrintPreviewCommand : NPrintPreviewCommand

{

public override void Execute()

{

if (Commander == null)

return;

NDrawingDocument document = Commander.Document;

if (document == null)

return;

NPrintManager manager = new NPrintManager(document);

manager.Layout = Nevron.GraphicsCore.PagedLayout.FitToPages;

try

{

manager.ShowPrintPreview();

}

catch (Exception ex)

{

MessageBox.Show("Failed to show the print preview dialog. Exception was: " + ex.Message);

}

}

public static void UpdateCmdBarManager(NDiagramCommandBarsManager cmdBarManager)

{

NDiagramCommand oldCommand = cmdBarManager.Commander.Commands.GetCommandFromId((int)DiagramCommand.PrintPreview);

cmdBarManager.Commander.Commands.Remove(oldCommand);

cmdBarManager.Commander.Commands.Add(new MyPrintPreviewCommand());

cmdBarManager.Recreate();

}

}

}

Parhaps there is another reason for the code not to work in your enviroment.
