我做了標籤,以從數據庫中獲得價值並將其鏈接起來。但問題是它只有一個價值,我希望它保持價值導航時認爲網站爲。標籤作爲動態導航
X> Y> Z ^> ....
這是我的代碼

如果(的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)
