'stop running the script' in IE

[Gijo]

 

 

Hi Team,

I have the below treeview and uses 'Load On Demand' and for certian nodes it has around 5000 child nodes and are throwing the javascript error 'stop running the script'. Below are what I tried.

1. In the NodeExpand event, I changed the expand mode to 'ServerSide', it worked fine. But I need AJAX.
2. I tried setting ScriptMode="Release" but didn't work.
3. I tried PersistLoadOnDemandNodes='false' and it worked. But I want to use server side events.

Regards,
Gijo Joseph.

 

<telerik:RadTreeView ID="RadTreeView" runat="server" EnableDragAndDrop="true"
onnodedatabound="RadTreeView_NodeDataBound"
onnodeexpand="RadTreeView_NodeExpand">
</telerik:RadTreeView>

 

 

 

 

protected void RadTreeView_NodeExpand(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e)
{
  List<Node> ltChilNodes = GetListofChildNodes();
  foreach (Node node in ltChilNodes)
  {
    RadTreeNode onDemandNode = new RadTreeNode(node.Name);
    onDemandNode.Attributes.Add("Attr1", node.Attr1);
    onDemandNode.Attributes.Add("Attr2", node.Attr2);
    onDemandNode.Attributes.Add("Attr3", node.Attr3);
    onDemandNode.Attributes.Add("Attr4", node.Attr4);
    onDemandNode.Attributes.Add("Attr5", node.Attr5);

    onDemandNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;

    e.Node.Nodes.Add(onDemandNode);
 }

}

Hello Gijo,

This is a common issue and unfortunately we have no control over it. 

There are a couple of things you can do to get rid of the problem:
1. Use WebService LoadOnDemand, which is the fastest available LoadOnDemand mode. You can take a look at the following demo for reference:
http://demos.telerik.com/aspnet-ajax/treeview/examples/programming/performance/defaultcs.aspx 
2. Instead of loading all the child nodes at once, you can load only a portion of them at a time. I've attached a sample project demonstrating the approach.
