Hi *,

I try to add a custom toolbar command

public class NCustomDiagramButtonCommand : NDiagramButtonCommand
{
// [...]

public NCustomDiagramButtonCommand()
: base((int)DiagramCommandRange.Misc, (int)DiagramCommand.LastCommandId + 1, "Custom command", "Custom button command in a custom toolbar.")
{
}

public override void Execute()
{
MessageBox.Show("NCustomDiagramButtonCommand was executed.");
}
// [...]
}

with

// create the custom buttom command if not already craated
if (customDiagramButtonCommand == null)
{
customDiagramButtonCommand = new NCustomDiagramButtonCommand();
Form.CommandBarsManager.Commander.Commands.Add(customDiagramButtonCommand);
}

to one of the menu entrys (the "Edit" menu) in the main menu bar with:

NMenuBar mainMenu = (NMenuBar)Form.CommandBarsManager.Toolbars["Main Menu"];
mainMenu.Commands[2].Commands.Add(NCommand.FromContext((NCommandContext)customDiagramButtonCommand.CreateUICommand()));

If I call this after
Form.CommandBarsManager.Recreate();
the new menu entry is shown, but if I clicked the new menu entry, the "Execute" procedure of the NCustomDiagramButtonCommand object isn't fired.

Why?

Hi Wilhelm,

You have to create the command that you add to the main menu Commands collection as follows:

int id = customDiagramButtonCommand.Id;
NCommandContext context = Form.CommandBarsManager.Contexts.ContextFromID(id);
NCommand cmd = NCommand.FromContext(context);

I hope this helps.
