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:

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

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

   var menu = <%= RadMenu1.ClientID %>;
   var text =   document.getElementById("openTextBox").value;
   var item = menu.FindItemByText(text);
   

3. When you get the instance of a particular item, you can call the Disable() / Enable() / Open() / Close() / etc. methods:

   function OpenItem()
   {
   	var menu = <%= RadMenu1.ClientID %>;
   	var text = document.getElementById("openTextBox").value;
   	
   	var item = menu.FindItemByText(text);
   	
   	if (item)
   	{
   		item.Open();
   	}
   	else
   	{
   		alert("Item with text '" + text + "' not found.");
   	}
   }
   
   function CloseItem()
   {
   	var menu = <%= RadMenu1.ClientID %>;
   	var text = document.getElementById("closeTextBox").value;
   	
   	var item = menu.FindItemByText(text);
   	
   	if (item)
   	{
   		item.Close();
   	}
   	else
   	{
   		alert("Item with text '" + text + "' not found.");
   	}
   }
