Merhaba arkadaslar bu makalemizde QueryString metodunu kullanarak DetailsView nesnesinde id no ya göre verilerimiz gösterecegiz. Default.aspx sayfamizda ki hyperlink nesnesinin NavigateUrl sini asagidaki gibi yapiyoruz.
HyperLink1.NavigateUrl = "~/Details.aspx?Id=2";
Bu sekilde hyperlink e tiklanildiginda Details.aspx sayfasina gidiyoruz ve Id degerini 2 olarak tasiyoruz.
Details.aspx sayfasinda asagidaki gibi QueryString metoduyla;
id = Convert.ToInt32(Request.QueryString["Id"]);
Id degerini id degiskenine atiyoruz ve bu degere göre sql sorgulamamizi yaparak, DetailsView da Id degerine göre gösterimi sagliyoruz.
