[Solved] very slow while using client side add, remove tree node?

[Elton]

Hi,

I m using client side code to move nodes from one tree to another.
My code here:

treeSrc.trackChanges();

treeDst.trackChanges();

var count = selectedNodes.length;

for(var i = 0; i < count; i++)

{

treeSrc.get_nodes().remove(selectedNodes[i]);

treeDst.get_nodes().add(selectedNodes[i]);

}

treeSrc.commitChanges();

treeDst.commitChanges();
...


When I work with several tree nodes it seems ok. However once I try to move 50 nodes at the same time it stucks for approximately 10sec!

Is there any problem with my code? Or some tips for this issue?

Regards,
Elton

Hello Elton,

I tried to reproduce the problem at our side, but to no avail. Removing of 55 nodes took less than 3 seconds. Attached, please find a small and running project on the matter. Download the files and give them a go. Click on any of the "Root node 1" children and all the children will be removed.

What am I missing?

Thank you again Nick,

I tried your example works well.

But I think it ll be a bit slower when I apply : 

trackChanges() and commitChanges().

In my case, for 50 tree nodes it may take 3,4 seconds to move (remove and add, I m tracking changes for 2 trees) and I think that's fine now.

Thanx,
Elton
