When the Telerik treeview is used and the node's ExpandMode is set to ServerSide, if we select the nodes, expand them or collapse them, we sometimes get the 0x80072746 error. Is there a way to avoid this error?

Here is the stacktrace for this error:

Exception of type 'System.Web.HttpUnhandledException' was thrown.;Inner exception: System.Web.HttpException: The remote host closed the connection. The error code is 0x80072746.

I Second this, but it happens while using RadUpload and cancelling the upload.
