NOV Schedule lets you fully customize the context menu shown when the user right clicks somewhere in the schedule view. To do so, you should create a class that inherits NScheduleContextMenu and override the methods you are interested in. Most commonly you will need to override one or both of the following methods:

• CreateElementSpecificCommands - creates context menu commands for the given element and adds them to the specified menu. The default implementation of this method checks whether the given element implements the INAppendContextMenuItems interface and if it does, calls its AppendContextMenuItems method.
• CreateCustomCommands - creates custom context menu commands.

The code example below demonstrates how to create a schedule context menu factory that adds a custom command at the bottom of the context menu:

public class CustomContextMenu : NScheduleContextMenu
{
    public CustomContextMenu()
    {
    }
    static CustomContextMenu()
    {
        CustomContextMenuSchema = NSchema.Create(typeof(CustomContextMenu), NScheduleContextMenu.NScheduleContextMenuSchema);
    }

    protected override void CreateCustomCommands(NMenu menu)
    {
        base.CreateCustomCommands(menu);

        // Create a context menu builder
        NContextMenuBuilder builder = new NContextMenuBuilder();

        // Add a custom command
        builder.AddMenuItem(menu, NResources.Image_Ribbon_16x16_smiley_png, CustomCommand);
    }

    public static readonly NSchema CustomContextMenuSchema;
}

When you've created your custom schedule context menu factory, you should create an instance of it and assign it to the ContextMenu property of the schedule view:

scheduleView.ContextMenu = new CustomContextMenu();
