数据库中的数据绑定到GridView在ASP.Net [英] Binding database data to the GridView in ASP.Net
问题描述
我尝试数据库中的数据绑定到C#和asp.net GridView控件。但我无法看到gridview.Rows的DATAS被添加到GridView但都是空的。当我运行SQLServer的在该查询,它提供了正确的result.I没有添加或更改任何code到ASP part.Should我?我找不到哪里出了问题:(请帮助..
MyConnection的= WebConfigurationManager.ConnectionStrings [KutuphaneConnectionString]的ConnectionString。
连接=新的SqlConnection(MyConnection的);
命令=新的SqlCommand();
connect.Open();
command.Connection =连接; 字符串komut =SELECT K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi FROM OduncIslemleri 0,Kitap K式O.kullaniciId =+会话[ID] +和O.kitapId = K.id;
尝试
{
的SqlCommand的SqlCommand =新的SqlCommand(); 的SqlCommand = connect.CreateCommand();
sqlCommand.CommandText = komut;
SqlDataAdapter的SDA =新SqlDataAdapter的(sqlCommand.CommandText,连接);
SqlCommandBuilder SCB =新SqlCommandBuilder(SDA);
//创建一个DataTable来保存查询结果。
数据表dTable =新的DataTable();
//填写的数据表。
sda.Fill(dTable);
GridView1.DataSource = dTable;
GridView1.DataBind(); }
赶上(SQLEXCEPTION)
{
//Console.WriteLine(e.StackTrace);
}reader.Close();
connect.Close();
下面是正确答案:
MyConnection的= WebConfigurationManager.ConnectionStrings [KutuphaneConnectionString]的ConnectionString。
连接=新的SqlConnection(MyConnection的);
字符串sorgu =选择K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi从Kitap K,OduncIslemleri O,其中O.kitapId = K.id和O.kullaniciId =+会话[ID];
SqlDataAdapter的SADP =新SqlDataAdapter的(sorgu,连接);
DataSet的DS =新的DataSet();
sadp.Fill(DS);
this.GridView1.DataSource = ds.Tables [0];
this.GridView1.DataBind();
connect.Close();
我也用在GridView的模板字段。也autogeneratedFields应该是真实的。我希望这有助于谁有同样的问题的人。
I try to bind database data to the gridview in c# and asp.net. But I couldn't see the datas in the gridview.Rows are added to the gridview but they are empty. When I run that query in SQLServer, it gives the correct result.I didn't add or change any code to the asp part.Should I? I couldn't find where is the problem :( please help..
myConnection = WebConfigurationManager.ConnectionStrings["KutuphaneConnectionString"].ConnectionString;
connect = new SqlConnection(myConnection);
command = new SqlCommand();
connect.Open();
command.Connection = connect;
string komut = "SELECT K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi FROM OduncIslemleri O,Kitap K WHERE O.kullaniciId=" + Session["id"] + " AND O.kitapId = K.id;";
try
{
SqlCommand sqlCommand = new SqlCommand();
sqlCommand = connect.CreateCommand();
sqlCommand.CommandText = komut;
SqlDataAdapter sda = new SqlDataAdapter(sqlCommand.CommandText, connect);
SqlCommandBuilder scb = new SqlCommandBuilder(sda);
//Create a DataTable to hold the query results.
DataTable dTable = new DataTable();
//Fill the DataTable.
sda.Fill(dTable);
GridView1.DataSource = dTable;
GridView1.DataBind();
}
catch (SqlException)
{
//Console.WriteLine(e.StackTrace);
}
reader.Close();
connect.Close();
Here is the correct answer :
myConnection = WebConfigurationManager.ConnectionStrings["KutuphaneConnectionString"].ConnectionString;
connect = new SqlConnection(myConnection);
string sorgu = "select K.ad,K.yazar,K.baskiNo,O.sonTeslimTarihi from Kitap K, OduncIslemleri O where O.kitapId = K.id and O.kullaniciId = "+ Session["id"];
SqlDataAdapter sadp = new SqlDataAdapter(sorgu, connect);
DataSet ds = new DataSet();
sadp.Fill(ds);
this.GridView1.DataSource = ds.Tables[0];
this.GridView1.DataBind();
connect.Close();
I also used template fields in Gridview. Also autogeneratedFields should be true. I hope this helps to the people who have the same problem
