TreeNodeExpandMode.WebService - Extra data

[Paul Fleming]

Hello,

We're in the process of replacing our old tree control with a new one. We've implemented the expand mode as serversidecallback but there is a noticeable delay in comparison to the old tree (several seconds). The old tree control uses web service node expansion. Although this feature is available with the Telerik TreeView control, it is severely limited. We need to not only add the child nodes, but also register other client data/scripts. With ServerSideCallBack, we're writing our dynamic javascript to the Category field. Could you suggest how we could get similar results from WebService expand mode?

e.g.

void AddNodeForWebServiceExpand(...)

{

RadTreeNodeData n;

n.Text = "My node";

n.Value = "N0";

/* add dynamic js */

n.<some string property> = "alert('name = My node; value = N0; extra data = <some extra data>')";

}

Regards,

Paul
