You should be using List of some type such as KeyValuePair or Tuple or your own class to store both values. For example,

var categories = new List<KeyValuePair<string, string>>();
while (reader.Read())
{
   categories.Add(new KeyValuePair<string, string>(reader["category_id "].ToString(), reader["cat_name"].ToString()));
}
ProductMainCategory.DataSource = Categories;
ProductMainCategory.DataValueField = "Key";
ProductMainCategory.DataTextField = "Value";
ProductMainCategory.DataBind();
