How to use BindJQuery

I am trying to create a gallery page using lightbox, the problem I have is not sure how I reference BindJQuery & CommonHelper in the following code in the codebehind, they both come up as errors.


protected override void OnPreRender(EventArgs e)
        {
            BindJQuery();

            string slimBox = CommonHelper.GetStoreLocation() + "Scripts/slimbox2.js";
            Page.ClientScript.RegisterClientScriptInclude(slimBox, slimBox);

            base.OnPreRender(e);
        }
        protected void Page_Load(object sender, EventArgs e)
        {

        }

Thanks in advance

Steve

PS Just found CommonHelper  ~~~ using NopSolutions.NopCommerce.Common.Utils;
