Question

我有这样的代码

    protected void rptCategory_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataRow dr = ((DataRowView)e.Item.DataItem).Row;
            LinkButton lnkcoursename = (LinkButton)e.Item.FindControl("lnkCategory");
             Label lblcount = (Label)e.Item.FindControl("lblCount");
            string k = lnkcoursename.CommandArgument.ToString();
            if (k != "0")
            {
                TrainingCourse traningCourse = new TrainingCourse();
                int count = traningCourse.CourseCount(Convert.ToInt32(k), "", "");
                if (count == 0)
                {
                    //This code is not working
                    dr.Delete();
                    dr.AcceptChanges();
                }
                else
                {
                    lblcount.Text = "(" + count + ")";
                }
            }
    }

现在我的问题是，如果我发现count = 0，那么我想从转发器中删除该行。我不想从数据库中删除它然后重新绑定它......

您尝试删除与数据源关联的行。但是对于这项任务来说，隐藏项目要好得多：

e.Item.Visible = false

我想删除转发器中的行
