This tutorial demonstrates how to use Action context menu in WebNotification. Action context menu provides a way for end users to access a list of available actions and perform an action against notification event.

1. Drag WebNotification control from ToolBox into the WebForm.
   
   
   
   
2. Create a WebService page in the same directory and name it "NotificationService.asmx". It will automatically create "NotificationService.cs" in the App_code folder. WebNotification control will look for GetNotifications method in the WebService. Use the following code for GetNotifications method:
   
   

   C#

   Copy Code

   [WebMethod] public WebNotificationEventCollection GetNotifications(WebNotificationEventArgs e) { WebNotificationEventCollection collection = new WebNotificationEventCollection(); WebNotificationEvent evnt = new WebNotificationEvent(); evnt.CaptionText = "Samples"; evnt.ContentText = "Hello world from WebNotification!\nCurrent time is:" + DateTime.Now.ToLongTimeString(); collection.Notifications = new WebNotificationEvent[] { evnt }; return collection; }

   
   
3. Open WebNotification Designer and set the following properties of WebNotification control:
   
   

   Properties	Values
   ServiceType	WebService
   ServiceUrl	NotificationService.asmx
   ShowActionDropdown	True

   
   
   
   
4. Add some menu items in Items property and specify a function name for OnClick event.
   
   
   
   
5. Add function doClick() that represents OnClick event:
   
   

   JavaScript	Copy Code
   function doClick(mi) { alert("Clicked : " + mi.Name); }

   
   
6. Run the page. Menu items will be displayed when Action context menu is clicked.
   
   
   
   When the menu item is clicked, an alert box will be displayed.
