A Scheduling/Diary Control/Component by Gravitybox Software LLC

The WebSchedule.NET control is an ASP.NET software component that allows you add scheduling to any ASP.NET application. The component supports many ViewModes. A ViewMode is one way to display data. For example, the most common ViewMode is dates on top and time on left. This is the traditional appointment book. The Viewmode property allows the WebSchedule.NET component to be very useful for dentists' and doctors' office applications. Information may be viewed in many different ways such as by room, provider (worker) or category. WebSchedule.NET was designed from the ground up with office scheduling in mind. You can schedule appointments based on one or more of the following: date, time, room, object, provider, or category. It is highly customizable with event notifications for virtually everything. Also appointment conflict resolution and display is built-in.

Supported Functionality:

Events - The most useful events are still present and allow you to override various drawing methods and catch Before and After events.
Colors - You may still customize the appearance of objects with the exception of using Transparency.
Schedule Area - You may define colored portions of a schedule to bring the users attentions to specific areas like "lunch hour". When using NoDropAreas, you will need to check the collection manually since there is no drag-drop move functionality.
Viewmodes - You can use any of 15 different viewmodes. Display date, time, room, or providers on any axis.
Appointment Icons - Even in HTML you can show icons on the left side of appointments. These are images files (GIF, JPG, etc) that are added to an appointment's IconCollection.
Look-and-Feel - The look and feel of the schedule is almost exactly the same. You can add headers and customize colors. Round appointments do not exist nor do transparent colors.
Searching - The collections for the WebSchedule are for the most part the same. As such you may still search the collections.
Advanced Graphics - You can also display Appointment bars, Time bars, headers, etc.
Data Binding - The most important new addition to the scheduling suite is the ability to bind data. With our new controllers you can access our predefined database format to store appointments, categories, providers, and rooms.

Unsupported Functionality:
Events - Some events that would have cause excessive post-backs are not supported, while many still are supported
Dialogs - Run-time dialogs (pop-up screens)
Transparency - Transparent backgrounds for appointment or other objects
Printing - There is no way to support printing from HTML. You may still have the browser print a page if you wish, but there is no built-in functionality to print only a portion of a schedule.
Drag-Drop Functionality - Since the control is rendered in a browser as HTML, appointments cannot be moved by drag-drop.
