Events from C# Control ? Urgent !!

Question

Hi all,
    Is there any way to handle events from a C# customcontrol in ABAP?
    When I used ActiveX controls, it was easy - just check by EventID in DISPATCH, and RAISE EVENT that would then be handled...
    But now, with C# controls, events are "delegate" functions, and I just can't figure out how to make ABAP subscribe to this tricky kind of event...
    Please, help!!!
Thanks,
Arnaldo.

This article will explain how to declare and use the C# events in your application as Event Control. You can design your event control in couple of mints, making your event as control will be easy for GUI developers to implement events in client side.
Here are the steps:
Create one Windows Application Project
Add “Component Class” using "Add New Item". This is going to be your Event Control.
Declare your delegate in your Event Control under your namespace
Now declare your event inside your Event Control class.
Also add the FireTheEvent method to fire the event.
Build the project.
Go to Form, then ToolBox, add the Event Control using “Add/Remove Items” menu by right clicking on the tool box.
Drag and drop the new control. Using the property window of the control you can easily implement the Event method in your application.
Call The FireTheEvent method in your button click after adding new button to your form.
Run the application and click on your button, you should see your Event firing.
Here's a list of all the events for the DataGrid control:

After referring to the DataGrid Event Handler (http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemwebuiwebcontrolsdatagriditemeventhandlerclasstopic.asp) information, I think you'll want your code to look something like this:
<%@ Page Language="C#" AutoEventWireup="True" %>
<%@ Import Namespace="System.Data" %>
<script language="C#" runat="server">
void Page_Load(Object sender, EventArgs e)
// Set things up...
void Item_Data_Bound(Object sender, DataGridItemEventArgs e)
// Your event code
</script>
