Hi friends,

    can anyone help me in solving this problem 

    i have 2 radtreeview
     displaying 2 different folders Hierarchy in the server

    i am trying to drag some files and folder of radtreeview1 to radtreeview2
    this works on the client side where i am draging but to implement it physically 
    where should i write a code (that is to move the files from location of tree1 to tree2)
