将数据网格绑定到数据集

Question

我一直在尝试将数据集分配为网格的源。所以，这就是我所做的：

        SqlCommand cmd = new SqlCommand("TEST",
                                               conn);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet d = new DataSet();
        da.Fill(d);
        grid2.DataSource = d;
        grid2.DataBind();

但是，我无法得到结果。网格在页面上不可见。可以请教一下方法吗？

您的代码不完整；但是，这是这样做的：

//notice how the connection is enclosed in a using block
using (SqlConnection conn = new SqlConnection("ConnectionString"))
{
        conn.Open();//don't forget to open the connection
        SqlCommand cmd = new SqlCommand("TEST",conn);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        DataSet d = new DataSet();
        da.Fill(d);
        grid2.DataSource = d;
        grid2.DataBind();
}

顺便说一句，您不需要 DataAdapter。你可以这样做：

//notice how the connection is enclosed in a using block
using (SqlConnection conn = new SqlConnection("ConnectionString"))
{
        conn.Open();//don't forget to open the connection
        SqlCommand cmd = new SqlCommand("TEST",conn);
        cmd.CommandType = CommandType.StoredProcedure;

        DataTable d = new DataTable();
        d.Load(cmd.ExecuteReader());
        grid2.DataSource = d;
        grid2.DataBind();
}
