RadTimeline for ASP.NET AJAX is based on the Kendo UI Timeline Widget. Thus, it exposes the Client-side API and methods offered by the widget and mainly provides a wrapper and API for working with the Timeline on the server.
        You can get Client-side object reference to the Timeline control in order to use its API like this: 
        
        
var radTimelineObject = $find("<%=RadTimeline1.ClientID %>");
        
    
    
        The most commonly used RadTimeline client-side methods are:
    
    
        - 
            get_orientation—Returns the orienation of the timeline axis.
        
- 
            open—Opens event details in horizontal mode.
        
- 
            expand—Expands an event in vertical mode.
        
- 
            collapse—Toggles the readonly state of the widget. When the widget is readonly it doesn't allow user input.
        
- 
            previous—Closes the widget popup.
        
- 
            next—Opens or closes the widget popup.
        
You can find the full client-side API of the control in the RadTimeline Client-side API documentation article.
    
    
        Get Client-side Object Reference to the Kendo Timeline widget in order to use its API
    
    
        There are two ways to get a reference to the Kendo Timeline widget in order to use its API:
        
            - 
                Use the get_kendoWidget method the RadTimeline client-side object exposes. You can get the RadTimeline object through the $find() MS AJAX method:
                
 
 varradTimelineObject  = $find("<%=RadTimeline1.ClientID %>"); //the standard script control object
 varkendoTimelineObject = radTimelineObject.get_kendoWidget(); //the Kendo widget
 
 
- 
                Use the standard Kendo approach for getting the widget through the data-attributes of the DOM element:
                
 
 varkendoTimelineObject = $telerik.$("#<%=RadTimeline1.ClientID %>").data("kendoTimeline"); //the jQuery selector must get the RadTimeline1 select element
