RE: ICallbackEventHandler

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi Salam,

Thank you for posting.

Regarding on the ASP.NET 2.0 script call back issue, based on my research,
it seems a document issue. As for the ICallBackEventHandler interface, it
contains two member functions we need to implement:

#ICallbackEventHandler Methods
http://msdn2.microsoft.com/en-us/library/dcc3kkye.aspx

The "RaiseCallbackEvent" function does not have return value, so we can not
return any data in this function. If we need to return data to client-side,
we need to use the "GetCallbackResult" function. e.g:

_cbResult is a page member variable
=====================================
#region ICallbackEventHandler Members

public string GetCallbackResult()
{
return _cbResult;

}

public void RaiseCallbackEvent(string eventArgument)
{
_cbResult = eventArgument + "__" + DateTime.Now.ToLongTimeString();


}

#endregion
==============================

Hope this helps. And sorry for the inconvenience the document problem
brings you.
