Drag and Drop between I-frames in DTMLX grid & Tree

Hi all,

I just struck with my design , i need to drag a element from my DHTMLX grid to my Tree. My tree
was placed in a separate frame .( Separate layout portion of the window ). Right now grid is not allowing me to drag and drop to a another frame. Is there any way to achieve this ?

Many thanks in advance!

Which browser you want to support ?
It must already work in IE, FF can be added by applying the regression fix ( contact us at support.dhtmlx.com or by email ), but there is no way to achieve functionality in Safari, Chrome and Opera - they block cross frame js events.
