We have the following scenario:

A user  selects a node from a tree on the left hand side, we then use the information from the node to populate the right hand side using:

function PerformAjaxRequest(i_Val)

                {  

                    $find("<%= MasterAjaxManager.ClientID %>").ajaxRequest(i_Val);                        

                }

Where MasterAjaxManager is a RadAjaxManager. My problem is that when a user then selects multiple nodes on the tree in quick succession, the right hand side becomes out of sync with the actual node selected on the tree. Hence I would like to cancel the request. The method I have observed for cancelling an request I have seen is the following:

function onRequestStart(sender, arguments)
{

return false;

}

In the onRequestStart function I would then poll a variable (delay in between each poll) which will tell me if another node has been selected if so the function will return false else carry on polling until either a timeout has been reached or the ajaxRequest has been successful.

I am contacting your team to see if there is a better way of doing this???

Many Thanks in Advance
