Load On Demand RadTreeView with Load On Demand RadToolTip
A common scenario is to display rich tooltips for treeview nodes. Here is how to achieve that using
RadToolTipManager and RadTreeView.
The example shows two independent approaches to obtain the same end result.
Approach #1 associates treeview nodes with the RadToolTipManager on the server by
adding those to the RadToolTipManager's TargetControls collection. Since RadTreeView nodes do not have
ID attribute set by default, this should be added to their Attributes collection.
Approach #2 relies on the client-side API of RadToolTipManager. For each treenode an onmouseover handler is attached
that will create and show a tooltip for that particular node.
The tooltips' content is loaded on demand through an AJAX call.
