RadToolBar provides a flexible client-side API - you can easily interact with the toolbar in the browser using the toolbar client-side object.

  1. Getting the RadToolBar client-side object: RadToolBar creates a client-side object with the ClientID of the toolbar. You can obtain the reference using the following javascript code: 
    var toolBar = $find("<%=RadToolBar1.ClientID%>");
  2. Once you get the client-side object of RadToolBar, you can use the findItemByText method to get the instance of a particular item. Example: 
    var toolBar = $find("<%= RadToolBar1.ClientID %>");
var text = $get("<%= TextBox1.ClientID %>").value;
var item = toolBar.findItemByText(text);
  3. When you get the instance of a particular item, you can call the disable() / enable() / etc. methods. 
    function toggleButton()
{
	var toolBar = $find("<%= RadToolBar1.ClientID %>");
	var text = $get("<%= TextBox1.ClientID %>").value;
	var item = toolBar.findItemByText(text);

	if (!item)
	{
		alert("There is no item with text \"" + text + "\"");
		return false;
	}
	
	if (!Telerik.Web.UI.RadToolBarButton.isInstanceOfType(item))
	{
		alert("The item with the specified text is not a button.\nOnly buttons can be checked/unchecked");
		return false;
	}

	if (Telerik.Web.UI.IRadToolBarDropDownItem.isInstanceOfType(item.get_parent()))
	{
		item.get_parent().showDropDown();
		item.toggle();
	}

	return false;
