I have further requirement from my last implementation using this - How to remove auto generated context menu items for the selected shape conditionally?Now I need to add some extra menu items to the context menu . I have added these command with sub menu but when i click these menu item then it does not fire the & nbsp ; CommandContextExecuted event as like Delete and other commands . Below is the code snippet to create extra menu items in the context menu ..
internal class CustomContextMenuBuilder : NDiagramContextMenuBuilder
{
public override NContextMenu BuildContextMenu(object obj)
{
NContextMenu contextMenu = null;
if (obj as NDrawingDocument == null)
{
contextMenu = new NContextMenu();
/* Added Delete option in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.Delete, false));
bool isConnectorMenu = obj as NRoutableConnector != null;
if (isConnectorMenu)
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.Reroute, true)); /* Added Reroute option in the context menu if connectors*/
/* Added SubmenuOrder in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.SubmenuOrder, !isConnectorMenu));
/* Added SubmenuRotateOrFlip in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.SubmenuRotateOrFlip, false));
if (offpageSystems.Count > 0) //Lets suppose it is list of String and I am creating a Sub menu
{
NCommand offpageCommand = new NCommand();
offpageCommand.Context = new NCommandContext(new NCommandProperties()
{
BeginGroup = true,
ShowArrowStyle = ShowArrowStyle.Default,
Name = "OffpageParent",
ID = ((int)DiagramCommand.LastCommandId + 20),
Text = "Offpage HVAC Systems"
});
contextMenu.Commands.Add(offpageCommand);
for (int cnt = 0; cnt < offpageSystems.Count; cnt++)
{
NCommand subCmd = new NCommand(new NCommandProperties()
{
Name = string.Format("OffpageChild{0}", cnt),
ID = ((int)DiagramCommand.LastCommandId + 20 + cnt),
Text = offpageSystems[cnt].SimModelName,
Tag = offpageSystems[cnt].RowReference
});
offpageCommand.Commands.Add(subCmd);
}
}
//DiagramCommandRange
}
return contextMenu;
}
internal class CustomContextMenuBuilder : NDiagramContextMenuBuilder
{
public override NContextMenu BuildContextMenu(object obj)
{
NContextMenu contextMenu = null;
if (obj as NDrawingDocument == null)
{
contextMenu = new NContextMenu();
/* Added Delete option in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.Delete, false));
bool isConnectorMenu = obj as NRoutableConnector != null;
if (isConnectorMenu)
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.Reroute, true)); /* Added Reroute option in the context menu if connectors*/
/* Added SubmenuOrder in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.SubmenuOrder, !isConnectorMenu));
/* Added SubmenuRotateOrFlip in the context menu */
contextMenu.Commands.Add(CreateCommand((int)DiagramCommand.SubmenuRotateOrFlip, false));
if (offpageSystems.Count > 0) //Lets suppose it is list of String and I am creating a Sub menu
{
NCommand offpageCommand = new NCommand();
offpageCommand.Context = new NCommandContext(new NCommandProperties()
{
BeginGroup = true,
ShowArrowStyle = ShowArrowStyle.Default,
Name = "OffpageParent",
ID = ((int)DiagramCommand.LastCommandId + 20),
Text = "Offpage HVAC Systems"
});
contextMenu.Commands.Add(offpageCommand);
for (int cnt = 0; cnt < offpageSystems.Count; cnt++)
{
NCommand subCmd = new NCommand(new NCommandProperties()
{
Name = string.Format("OffpageChild{0}", cnt),
ID = ((int)DiagramCommand.LastCommandId + 20 + cnt),
Text = offpageSystems[cnt].SimModelName,
Tag = offpageSystems[cnt].RowReference
});
offpageCommand.Commands.Add(subCmd);
}
}
//DiagramCommandRange
}
return contextMenu;
}
Please suggest me the correct way to create context menu items which should work as like ' Action '& nbsp ; DiagramCommandRange . How can i create another command range so that these submenu work like them ?? Thanks in Advance

Hello Niranjan , When you create the context menu in BuildContextMenu you need to pass the Manger property into the constructor parameters : contextMenu = new NContextMenu(Manager); contextMenu = new NContextMenu(Manager);
You need to create the offpageCommand as follows :
NCommandContext offpageContext = new NCommandContext();
NCommand offpageCommand = NCommand.FromContext(offpageContext);
Manager.Contexts.Add(offpageContext);
NCommandContext offpageContext = new NCommandContext();
NCommand offpageCommand = NCommand.FromContext(offpageContext);
Manager.Contexts.Add(offpageContext);
Note that you need to add the command ' s context to the Manager ' s context collection . Children commands need to be created the same way but instead of adding their context to the Manager ' s Contexts collection you have to add them to the Contexts collection of their parent command : NCommandContext context = new NCommandContext();
NCommand subCmd = NCommand.FromContext(context);
offpageCommand.Context.Contexts.Add(context); NCommandContext context = new NCommandContext();
NCommand subCmd = NCommand.FromContext(context);
offpageCommand.Context.Contexts.Add(context);
This way when these custom commands were executed the & nbsp ; CommandContextExecuted event should fire .
