Question

我使标签具有来自数据库的价值并将其链接起来。但问题是它只有一个值，我希望它在导航时认为网站保持价值。

这是我的代码

if（Request.QueryString [“Category_Id”]！= null） {

        Banar.ImageUrl = "Handlers/Banner.ashx?Category_Id=" + Request.QueryString["Category_Id"] + "";
        using
    (SqlConnection conn = Connection.GetConnection())
        {
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = conn;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "Navcategory";
            cmd.Parameters.Add(Parameter.NewInt("@Category_Id", Request.QueryString["Category_Id"]));
            SqlDataReader dr = cmd.ExecuteReader();
            if (dr.Read())
            {

                    LblNavigaton.Visible = true;

                    LblNavigaton.Text = dr[i].ToString();
                    NavHref.HRef = "ListView.aspx?Category_Id=" + Request.QueryString["Category_Id"] + "";

            }

        }
    }
    else if (Request.QueryString["ProductCategory_Id"] != null)
    {
        Banar.ImageUrl = "Handlers/ProCatBanner.ashx?ProductCategory_Id=" + Request.QueryString["ProductCategory_Id"] + "";
        using
        (SqlConnection conn = Connection.GetConnection())
        {
            SqlCommand cmd = new SqlCommand();
            cmd.Connection = conn;
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.CommandText = "NavProductcategory";
            cmd.Parameters.Add(Parameter.NewInt("@ProductCategory_Id", Request.QueryString["ProductCategory_Id"]));
            SqlDataReader dr = cmd.ExecuteReader();
            if (dr.Read())
            {
                LblNavigaton.Visible = true;
                LblNavigaton.Text = dr["Name"].ToString();
                NavHref.HRef = "ListView.aspx?ProductCategory_Id=" + Request.QueryString["ProductCategory_Id"] + "";
            }
            else
            {
                LblNavigaton.Visible = true;
                LblNavigaton.Text = Page.Title;
            }

        }

Answer 1

好吧，您可以在每次加载新网页时检索该值，或将其作为网址参数传递，或者阅读cross-page posting。

Answer 2

如果您想在用户登录时将该值保留在<{1}}“整个”网站中，那么您可以在这种情况下使用LblNavigaton.Text。比如：

Session

标签为动态导航
