The reason why i asked this question is because by using LoadMore... functionality to add nodes, internet explorer is becomming exponentially slow if the number of nodes added start becomming more than 3000. I am using the procedure explained in the following link to add nodes from javascript :
http://www.telerik.com/community/code-library/aspnet-ajax/treeview/radtreeview-s-addnodesto-method-as-best-performing-solution-for-creating-new-or-moving-existing-nodes-on-the-client-side.aspx
var treeNodeCollection = new Array();
for (var nodeIndex = 0; nodeIndex < nodeLength; archiveIndex++) {
var node = new Telerik.Web.UI.RadTreeNode();
var data = MainDataArray[nodeIndex];
node.set_text(data.Text);
node.set_value(data.Value);
var imageUrl = data.ImageUrl.replace('~\\', '');
node.set_imageUrl(imageUrl);
//add a dummy node to this node
node.get_nodes().add(DummyNode());
treeNodeCollection[nodeIndex] = node;
nodeIndex++;
}
treeView.addNodesTo(currentNode, treeNodeCollection);
The code works fine with chrome, but with IE it goes on becomming slower and slower.
Do we have any known issue or limitation, because our main aim is to load around 50000 nodes under one node.
