' To generate toolbar items at visual design,- the editor for Toolbar property can be used.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
		If (Me.IsPostBack) Then
			Return
		End If

		'-------------------
		' Add another item to a build-in Insert drop-down list
		Dim dropDownInsert As ToolbarDropDown = CType(Me.WebHtmlEditor1.FindByKeyOrAction("Insert"), ToolbarDropDown)
		If (Not dropDownInsert Is Nothing) Then
			dropDownInsert.Items.Add(New ToolbarDropDownItem("Signature2", "<span style='background-color:red'>My Signature<span>"))
