Question

我头脑发热，无法弄清楚为什么我的数据表在绑定到gridview之前没有保存到会话中？

始终为空。

这是我的代码。 Settings.AutoRedirectMode= RedirectMode,Permanent;应包含数据。但是，当我去提取gridview排序数据时，它是空的

Session["Data"] = dts;

你的代码对我来说很好......

protected void Page_Load(object sender, EventArgs e)
{
    PopulateOrderList();
}

private void PopulateOrderList()
{
    DateTime d;
    DateTime d2;
    DataTable dts = new DataTable();
    dts.Columns.Add("OrderDate", typeof(string));
    dts.Columns.Add("OrderNumber", typeof(string));
    dts.Columns.Add("OrderItemSKUName", typeof(string));
    dts.Columns.Add("SKUNumber", typeof(string));
    dts.Columns.Add("OrderItemStatus", typeof(string));
    dts.Columns.Add("OrderItemUnitCount", typeof(string));
    dts.Columns.Add("mtrx_Code2", typeof(string));

        DataRow drNew = dts.NewRow();
        drNew["OrderDate"] = DateTime.Now.ToShortDateString();
        drNew["OrderNumber"] = "122";
        drNew["OrderItemSKUName"] = "sku";
        drNew["SKUNumber"] = "skunum";
        drNew["OrderItemStatus"] = "Done";
        drNew["OrderItemUnitCount"] = "1290";
        drNew["mtrx_Code2"] ="abc123";
        dts.Rows.Add(drNew);

    Session["Data"] = dts;
    gridview.Visible = true;
    gridview.DataSource = dts.DefaultView;
    gridview.DataBind();


}

protected void gridview_SortCommand(object source, DataGridSortCommandEventArgs e)
{
    DataTable dt = (DataTable)Session["Data"];
}

C＃Datatable不在Session中保存
