    Hello Said,

    Thank you for contacting the infragistics support!

    The reason for the postback that you observe is that you have set  

    <AutoPostBackFlags NodeClick="On" />

    If you remove the "NodeClick" flag, the page will not refresh when a node is clicked. Is there a reason for you to enable this flag? If it is so - please provide more information about the scenario that you want to execute.

    Best regards,

    Alexander
