Question

I am using Sitecore and I have to show the first page in a collection of pages. Here is my code so far:

private Item currItem = Sitecore.Context.Item;
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (currItem.HasChildren || currItem.TemplateID == new Sitecore.Data.ID("45D58815-A301-4393-9BA0-30A00C9BB993"))
            {
                var getFirstChild = (from Item item in currItem.GetChildren()
                                     select item).First();
                if (getFirstChild.TemplateID == new Sitecore.Data.ID("45D58815-A301-4393-9BA0-30A00C9BB993") && getFirstChild != null)
                {
                    //Server.Transfer(getFirstChild.Paths.Path);
                }

                else
                {
                    //Load Generic Page!
                }
            }
            else
            {
                //Load Generic Page!!!
            }
        }
    }

You can use Response.Redirect or Server.Transfer. I would recommend Response.Redirect if you can:

Server.Transfer Vs. Response.Redirect

EDIT:

OK you can do this:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (currItem.HasChildren || currItem.TemplateID == new Sitecore.Data.ID("45D58815-A301-4393-9BA0-30A00C9BB993"))
            {
                var getFirstChild = (from Item item in currItem.GetChildren()
                                     select item).First();
                if (getFirstChild.TemplateID == new Sitecore.Data.ID("45D58815-A301-4393-9BA0-30A00C9BB993") && getFirstChild != null)
                {
                    Response.Redirect(getFirstChild.Paths.Path);
                }

                else
                {
                    //Load Generic Page!
                }
            }
            else
            {
                //Load Generic Page!!!
            }
        }
    }

Response is a property of the Page so you can use it to redirect.
