HOW-TO
Create a method which returns a javascript array containing all RadControls of a particular type (combobox, menu, treeview, etc.)


SOLUTION
This article explains how to create a method which returns an array of all RadTreeView controls on the page.
The same approach could be used to return an array of all RadMenu, RadTextBox, etc. controls on the page.

Here is the javascript method:

function get_allRadTreeViews() 
{ 
    var allRadTreeViews = []; 
    var allRadControls = $telerik.radControls; 
     
    for (var i = 0; i < allRadControls.length; i++) 
    { 
        var element = allRadControls[i]; 
         
        if (Telerik.Web.UI.RadTreeView && element instanceof Telerik.Web.UI.RadTreeView) 
        { 
            Array.add(allRadTreeViews, element); 
        } 
    } 
    return allRadTreeViews; 
} 

This method iterates through the built-in radControls array which contains all RadControls on the page and checks the type of every item.

Here is one simple usage of the above method:

function pageLoad() 
{ 
    for (var i = 0; i < get_allRadTreeViews().length; i++) 
    { 
        var tree = get_allRadTreeViews()[i]; 
        tree.get_nodes().getNode(0).select(); 
    } 
}
