Hi guys, newbie question: 

how do you send a message (generated on the server side) to the user after a cell has been updated?

The grid I'm working on has: 

LoadOnDemand="Xml"  

So this will not work on the asynchronous callback (correct me if I'm wrong):

Page.ClientScript.RegisterClientScriptBlock(Page.GetType(), "FeedbackMsg", "var StrFeedbackMsg = '" + msg  + "';", true);

Thanks in advance !
