Question

public partial class 公文流转系统_ViewFlow : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            BindDocFlowData();
        }
    }
    private void BindDocFlowData()
    {
        DocFlow flow = new DocFlow();
        SqlDataReader recf = flow.GetDocFlows();        DataTable dataTable = new DataTable();
        dataTable = SystemTools.ConvertDataReaderToDataTable(recf);        DataSet ds= new DataSet("DocFlow");
        ds.Tables.Add(dataTable);        dgFlowList.DataSource = ds;
        dgFlowList.DataBind();
    }
}这是一个绑定GridView的代码,编译是成功的，但是运行起来不知为什么会出现错误提示"ID 为“dgFlowList”的 GridView 的数据源没有任何可用来生成列的属性或特性。请确保您的数据源有内容
"，请帮忙解决 谢谢
