Question

enter image description here受保护的子rptRps_ItemDataBound（ByVal sender As Object，ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs）处理rptRps.ItemDataBound

      If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then

            Dim valueReceived As Integer = CType((CType(e.Item.DataItem, DataRowView))("netValue"), Integer)

            If valueReceived < 0 Then

                CType(e.Item.FindControl("trItemr00"), HtmlTable).Style.Add("litLastestLog", "whatever")

                'CType(e.Item.FindControl("litLastestLog"), Label).Text = "whatever"

            End If

        End If

 <td class="RepeaterItemCell_m" style="width: 4%; text-align: center">
                        <%# DataBinder.Eval(Container.DataItem, "LastDescrLog").ToString%>
                    </td>

当我运行conde时显示此消息“对象引用未设置为对象的实例”。我不知道我做了什么...... 我想在这里展示新消息。

 <td class="RepeaterItemCell_m" style="width: 4%; text-align: center">
                        <%# DataBinder.Eval(Container.DataItem, "LastDescrLog").ToString%>
                    </td>
