thanks first for a great Wisej.
in MDI application, I can not access WebMethod from initScript with App keyword.Window.WebMethodofXXX();
I´m not sure I understood the structure where you´re trying to call the method.
Can you please provide us with a sample code showing what you´re intending to do ?
If you prefer you can also send it to frankATiceteagroup.com
Thanks in advance !
