private void databind()
{
SqlConnection connection = db.createconnection();
connection.Open();
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = new SqlCommand("select * from lyb order by id desc", connection);
DataSet ds = new DataSet();
sda.Fill(ds, "lyb");
System.Web.UI.WebControls.PagedDataSource ps = new PagedDataSource();
ps.DataSource = ds.Tables["lyb"].DefaultView;
this.DataList1.DataSource = ps;
this.DataList1.DataBind();
connection.Close();
}
{
SqlConnection connection = db.createconnection();
connection.Open();
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = new SqlCommand("select * from lyb order by id desc", connection);
DataSet ds = new DataSet();
sda.Fill(ds, "lyb");
System.Web.UI.WebControls.PagedDataSource ps = new PagedDataSource();
ps.DataSource = ds.Tables["lyb"].DefaultView;
this.DataList1.DataSource = ps;
this.DataList1.DataBind();
connection.Close();
}
你的项目中有db这个类么？这个就是你用的db.createconnection();
你需要修改为
类名 db=new 类名();
SqlConnection connection = db.createconnection();
…………
如果没有你可以修改为：
private void databind()
{
SqlConnection connection = new SqlConnection("server=127.0.0.1;uid=sa;pwd=;database=数据库名;");
connection.Open();
SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = new SqlCommand("select * from lyb order by id desc", connection);
DataSet ds = new DataSet();
sda.Fill(ds, "lyb");
System.Web.UI.WebControls.PagedDataSource ps = new PagedDataSource();
ps.DataSource = ds.Tables["lyb"].DefaultView;
this.DataList1.DataSource = ps;
this.DataList1.DataBind();
connection.Close();
}
