Adding 100's of tree nodes to tree view at client side.

[Mufaddal]

Question: We are currently adding 100's of nodes in a tree view control using javascirpt function. We are getting json objects in java script method from WCF service which we then add to tree view, The problem is that this whole process is taking huge amount of time. What could be an efficient way to perform this operation...???

Hi Mufaddal,

We suggest that you try the addNodesTo client-side method of the RadTreeView. It is specially optimized for maximum performance and works the following way:

1) The first param should be the node/treeview to add nodes to.
2) The second param is collection of client-side RadTreeNode objects.

Here is sample usage:

var treeView = $find("RadTreeView");
treeView.addNodesTo(treeView, nodes)

All the best,
