Telerik RadMenu provides a flexible client-side API. You can easily interact with the menu in the browser using the menu client-side object.

1. Getting the RadMenu client-side object

RadMenu creates a client-side object with the ClientID of the menu. You can obtain the reference using the following JavaScript code:

  Copy Code
var menu = <%= RadMenu1.ClientID %>;

2. Getting the instance of a particular RadMenuItem

Once you get the client-side object of RadMenu, you can use the FindItemByText() method to get the instance of a particular item. Example:

  Copy Code
var menu = <%= RadMenu1.ClientID %>;
var item = menu.FindItemByText(text);

3. Calling a client-side method

When you get the instance of a particular item, you can call a client-side method to perform a task. Consider the following examples:

  • Open()
  Copy Code
function OpenItem()
{
   var menu = <%= RadMenu1.ClientID %>;
   var item = menu.FindItemByText(text);
   if (item)
   {
       item.Open();
   }
   else
   {
       alert("Item with text '" + text + "' not found.");
   }
}

 

  • Close()
  Copy Code
function CloseItem()
{
   var menu = <%= RadMenu1.ClientID %>;   
   var item = menu.FindItemByText(text);
   if (item)
   {
       item.Close();
   }
   else
   {
       alert("Item with text '" + text + "' not found.");
   }
}

 

  • Disable()
  Copy Code
function DisableItem()
{
   var menu = <%= RadMenu2.ClientID %>;
   var item = menu.FindItemByText(text);
   if (item)
   {
       item.Disable();
   }
   else
   {
       alert("Item with text '" + text + "' not found.");
   }
}

 

  • Enable()
  Copy Code
function EnableAll()
{
   var menu = <%= RadMenu2.ClientID %>;
   for (var i = 0; i < menu.AllItems.length; i++)
   {
       menu.AllItems[i].Enable();
   }
}

 

The code block <%= ... %> needs to be placed inside the BODY element of the page. See Atlas support for details.
