This example shows how to use the client-side API of Telerik TreeView for ASP.NET MVC.

To use the client-side API you should first retrieve the treeview client-side object. The following code snippet shows how to do this:

<script type="text/javascript">
function getTreeView(){
    //"TreeView" is the value specified by the Name() method.
    var treeview = $("#TreeView").data("tTreeView");
    return treeview;
}
</script>

These are the available client-side methods:

• treeview.expand(node) - expands a treeview node.
• treeview.collapse(node) - collapses a treeview node.
• treeview.enable(node) - enables a treeview node.
• treeview.disable(node) - disables a treeview node.
• treeview.getItemText(node) - gets the text of a treeview node.
• treeview.getItemValue(node) - gets the value of a treeview node. If the value is not set, returns the node text.
• treeview.nodeCheck(node, isChecked) - checks/unchecks a treeview node that has a checkbox, depending on the value of isChecked.

All of the above methods accept node as either a DOM element, jQuery selector or a jQuery object.
