Adding custom events to calendar

The article describes how to add custom events for the IDelivery object type to the calendar. The object is used to register orders for delivery. The IDelivery object contains the following fields:

1. Basic fields (Name, Date Created, Date Modified, Author, Change Creator);
2. Dispatch date (date/time);
3. Expected delivery date (date/time);
4. Delivery address (text);
5. Shipment delivered (Yes/No);
6. Executor (user, connection type - single);
7. Informed User (User, connection type - many-to-many).

There are two ways to add a custom event type to the calendar:

1. In the Calendar section, choose the event time/date and click on it; a popup window will appear with a list of all available events types;
2. In the Calendar section, click on the "Add" button; a list of all possible events will open.

Extension methods (interface)

The extension point (interface) IEventAddAction has the following methods:

/// <summary>
/// Button UID
/// </summary>
string Uid { get; }
 
/// <summary>
/// Name
/// </summary>
string Name { get; }
 
/// <summary>
/// Link to the form that adds an event 
/// To define the start date and the end date of the event the following expressions can be added to the URL {0} – start date, {1} – end date 
/// for example - /Event/Add?start={0}&end={1}
/// return urlHelper.Action("Add", "NameController", new { area = RouteProvider.AreaName, start = "{0}", end = "{1}" });
/// </summary>
string Url(RequestContext context);
 
/// <summary>
/// A parameter that opens URL in a modal window. If the parameter is null, the link opens in the parent window 
/// for example - new { id = "meetingWindow",title = "Create meeting", width = 800, onOpenScript = "alert(’open’)"}
/// </summary>
dynamic WindowSettings { get; }
 
/// <summary>
/// Link to an action icon 
/// </summary>
string Icon { get;  }
 
/// <summary>
/// Display order
/// </summary>
int Order { get; }
 
/// <summary>
/// Whether to use this action for shared calendars 
/// </summary>
bool AllowInShared { get; }
