if (!this.Page.ClientScript.IsClientScriptBlockRegistered(this.GetType(), "jquery.autocomplete.css"))
this.Page.ClientScript.RegisterClientScriptBlock(
this.GetType(),
"jquery.autocomplete.css",
"<link href='" + ResolveClientUrl("~/css/jquery.autocomplete.css") + "' rel=\"stylesheet\" />");

if (!this.Page.ClientScript.IsClientScriptIncludeRegistered(this.GetType(), "jquery.autocomplete.js"))
this.Page.ClientScript.RegisterClientScriptInclude(
