Question

我已经尝试了所有可以在网上找到的文章的组合，并且目前正在拔头发。下面的代码似乎甚至没有尝试进行数据绑定..当未对“引发异常”行进行注释时，它不会引发异常。

我尝试仅通过IEnumerable而不是datatable / datarows传递DataTable，但是我得到“ DataBinding：'System.Data.DataTable'不包含名称为'dateCompleted'的属性”。

任何帮助将不胜感激...

C＃

protected void runReportForUser(Guid UserID)
    {
        pnCard.Visible = true;
        pnNoPoints.Visible = false;

        using (var db = new db())
        {
            // scorecard logic

            var u = userProfile.get(UserID);

            var t = db.Database.SqlQuery<DataTable>("exec ReturnEntities '" + u.userID + "'").FirstOrDefault();
            //rptEvents.DataSource = t.ToArray()[0];

            rptEvents.DataSource = t.Rows;
            //rptEvents.DataSource = t;   

            rptEvents.DataBind();

        }
    }


protected void rptEvents_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            //throw new Exception("Test")
            DataRow dr = (DataRow)e.Item.DataItem;

            ((Label)e.Item.FindControl("lblDate")).Text = dr[0].ToString();
            //((Label)e.Item.FindControl("lblDate")).Text = DataBinder.Eval(e.Item.DataItem, "dateCompleted").ToString();
            ((Label)e.Item.FindControl("lblCategory")).Text = dr[1].ToString();
            ((Label)e.Item.FindControl("lblName")).Text = dr[2].ToString();
            ((Label)e.Item.FindControl("lblPointsValue")).Text = dr[3].ToString();

        }
    }

ASPX：

 <table width="100%" cellpadding="0" cellspacing="0" border="0">
        <tr>
            <th>Date</th>
            <th>Category</th>
            <th>Points Earned</th>
        </tr>
        <asp:Repeater ID="rptEvents" runat="server" OnItemDataBound="rptEvents_ItemDataBound">
            <ItemTemplate>
                <tr id="trEvents" runat="server">
                    <td><asp:Label ID="lblDate" runat="server" /></td>
                    <td><asp:Label ID="lblCategory" runat="server" /></td>
                    <td><asp:Label ID="lblName" runat="server" /></td>
                    <td><asp:Label ID="lblPointsValue" runat="server" /></td>
                </tr>
            </ItemTemplate>
        </asp:Repeater>
    </table>

在尝试了很多不同的东西后，我得以弄清楚。我最终不得不使其成为与表结构匹配的用户定义类的列表。看起来下面两种绑定方式都有效。

这里是为了帮助别人：

protected void runReportForUser(Guid UserID)
    {
        pnCard.Visible = true;
        pnNoPoints.Visible = false;

        using (var db = new db())
        {
            // scorecard logic

            var u = userProfile.get(UserID);

            var t = db.Database.SqlQuery<EntityHistory>("exec dbo.ReturnEntities '" + u.userID.ToString() + "'");
            List<EntityHistory> EntityList = t.ToList<EntityHistory>();
            rptEvents.DataSource = EntityList;
            rptEvents.DataBind();

        }
    }

protected void rptEvents_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
        EntityHistory EH = (EntityHistory)e.Item.DataItem;
            ((Label)e.Item.FindControl("lblDate")).Text = EH.dateCompleted;
            ((Label)e.Item.FindControl("lblCategory")).Text = DataBinder.Eval(e.Item.DataItem, "Category").ToString();
            ((Label)e.Item.FindControl("lblName")).Text = DataBinder.Eval(e.Item.DataItem, "Name").ToString();
            ((Label)e.Item.FindControl("lblPointsValue")).Text = DataBinder.Eval(e.Item.DataItem, "MaxPointsEach").ToString();
        }
    }

public class EntityHistory
{
    public Guid UserID { get; set; }
    public String dateCompleted {get;set;}
    public String Category { get; set; }
    public String Name { get; set; }
    public Int32 MaxPointsEach { get; set; }
}
