Hello,

We have some trees with lots of nodes. Drag and drop is enabled so users can re-order the nodes. When a user wants to drag a node from the top of the list to the bottom, the page doesn't automatically scroll. They have to drop the node halfway and manually scroll to continue dragging. Is there anyway to have the page automatically scroll when a user is dragging a node up or down a long tree?

Thanks!

Client-side databind only on demand

I'm implementing client-side databinding on a grid.
On the page's initial load the grid is automatically binded on client-side although the user should specify some data first.
So, with javascript, is there a way to rebind the grid only when rebind() is manually called? For example rebind is automatically triggered when filter() is called.

Thanks
