解决repeater中外键的代码

首先，托俩控件  HiddenField   和  label

   HiddenField 是用来保存数值， Label是用来在Repeater中显示数值

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemIndex > -1)
        {
            HiddenField HiddenFieldNewsTyId = (HiddenField)e.Item.FindControl("HiddenFieldNewsTyId");
            Label LabelNewsTyName = (Label)e.Item.FindControl("LabelNewsTyName");

            if (HiddenFieldNewsTyId != null)
            {
                NewsType newstype = NewsTypeManager.SelectOne(Convert.ToInt32(HiddenFieldNewsTyId.Value));
                LabelNewsTyName.Text = newstype.NewsTypeName;
            }
        }
    }

这样就轻松解决在repeater中不能显示外键的问题了！
