    Hi Burak.

    It sounds like 'nodeProperty might be null?

    Could you do a null check on nodeProperty before you call nodeProperty.Value?

    Have you made sure curNode is not null?

    Looking at https://our.umbraco.org/forum/developers/api-questions/46586-Get-current-node-as-IPublishedContent it looks like Node.GetCurrent doesn't work after Umbraco 4. Try replacing it with CurrentPage or with the UmbracoHelper.

    Sorry to hear that. Did you make sure curNode is not null? Since it seems Node.GetCurrent() is obsolete.

    Otherwise do you have Visual Studio? Could you try debugging to se which variable in your code is null. Without debugging it's more or less guessing..

    Make sure that curNode is not null. Best to always check it before calling the property. And make sure that the docType of that node has redirectionURL property.

    Hi burak.

    To be honest it's been a wile since I worked with Umbraco 6 and WebForms, but here is a try:

    <%@ Import Namespace="Umbraco.Web" %>

<script runat="server">protected void Page_Load(object sender, EventArgs e)
    {
        var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
        var curNode = umbracoHelper.AssignedContentItem;
        string redirect = null;

        if (curNode != null && curNode.HasProperty("redirectionURL") && curNode.HasValue("redirectionURL"))
        {
            var redirectionUrl = curNode.GetProperty("redirectionURL");
            redirect = redirectionUrl.Value.ToString();
        }

        if (curNode != null && curNode.HasProperty("redirectionPage") && curNode.HasValue("redirectionPage") && string.IsNullOrEmpty(redirect))
        {
            var redirectionPage = curNode.GetProperty("redirectionPage");
            redirect = umbracoHelper.TypedContent(redirectionPage.Value.ToString()).Url;
        }

        if (!string.IsNullOrEmpty(redirect))
        {
            Response.Redirect(redirect);
        }
    }

</script>

    Make sure that you dont miss <%@ Import Namespace="Umbraco.Web" %>, it's very important.
