I have two issues in the drag and drop functionality between two treeviews.
The drag and drop is going very smooth as long as I want drag and drop small number of nodes between the two treeviews ( for examples 10 nodes , some hunderts nodes or even few thousands nodes ).
Issue 1 :
When I try to drag and drop for more than few thousands of nodes between the two treeviews, I got the error which say (Maximum request length exceed).
When I drag and drop really huge number of nodes like ( 300000 nodes for example ) , usually the error is ( not enough memroy or out of memroy)
So please advise me what can I do in both cases because these cases are valid scenarios in my application.
I will be waiting for your reply.
