ListView项已创建回发

我对ListView的工作方式有点迷茫。

protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
{
    DataRow myRow;
    DataRowView myRowView;
    myRowView = (DataRowView)e.Item.DataItem;
    myRow = myRowView.Row;
    HtmlTableRow myTR = (HtmlTableRow)e.Item.FindControl("trRow");
    HtmlTableCell myTC = (HtmlTableCell)e.Item.FindControl("tdCell");

    Label myCB = (Label)e.Item.FindControl("ResultLabel1");
    if (myRow["Result"].ToString().Equals("true"))
        myTC.Style.Value = "background-color:#00FF00;color: #000000;";
    else
        myTC.Style.Value = "background-color:#FF0000;color: #000000;";
}

ListView有一个寻呼机,这会导致对ItemCreated的回发,我无法再次访问dataRow。

有没有什么建议可以帮我处理回发邮件?

更新: 我将代码更改为读取名为ResultLabel1的标签的实际值,该值为True/False,但它返回一个空字符串。。我认为这比从数据集中读取结果要好。有人能看出哪里不对吗?

代码:

        protected void ListView1_ItemCreated(object sender, ListViewItemEventArgs e)
    {
        HtmlTableRow myTR = (HtmlTableRow)e.Item.FindControl("trRow");
        HtmlTableCell myTC = (HtmlTableCell)e.Item.FindControl("tdCell");

        // Retrieve the current item.
        ListViewItem item = e.Item;

        // Verify if the item is a data item.
        if (item.ItemType == ListViewItemType.DataItem)
        {
            // Get the Label ResultLabel1 control in the item.
            Label myCB = (Label)item.FindControl("ResultLabel1");


            if (myCB.Text.Equals("True"))
                myTC.Style.Value = "background-color:#00FF00;color: #000000;";
            else
                myTC.Style.Value = "background-color:#FF0000;color: #000000;";

        }
    }

            <ItemTemplate>
            <tr id="trRow" runat="server" style="">
                <td>
                    <asp:Label ID="idLabel" runat="server" Text='<%# Eval("id") %>' />
                </td>
                <td>
                    <asp:Label ID="DateTime_StartLabel" runat="server" 
                        Text='<%# Eval("DateTime_Start") %>' />
                </td>
                <td>
                    <asp:Label ID="DateTime_EndLabel" runat="server" 
                        Text='<%# Eval("DateTime_End") %>' />
                </td>
                <td>
                    <asp:Label ID="TestCaseNameLabel" runat="server" 
                        Text='<%# Eval("TestCaseName") %>' />
                </td>
                <td>
                    <asp:Label ID="ModelNameLabel" runat="server" Text='<%# Eval("ModelName") %>' />
                </td>
                <td id="tdCell" runat="server">
                    <asp:Label ID="ResultLabel1" runat="server" 
                        Text='<%# Eval("Result") %>' />
                </td>
            </tr>
        </ItemTemplate>
