如何获得在直放站文字内容的价值 [英] How to get literal content value in Repeater

问题描述

我有一个转发器，如下所示。如何获得报告ID在code的后面（从内hiddenContent2前pression）？

这位前pression是

 ＆LT;％＃的eval（ReportID）％＆GT;
 

注：I preFER，做一个方法的不可以使用的FindControl

。

ASP.NET

 ＆LT; ASP：直放站ID =rptReports=服务器＆GT;
                    ＆LT; HeaderTemplate中＆GT;
                        ＆LT; D​​IV＆GT;
                        ＆LT; / DIV＆GT;
                    ＆LT; / HeaderTemplate中＆GT;
                    ＆LT;的ItemTemplate＆GT;

                        ＆LT; D​​IV ID =repeaterIdentifier级=repeaterIdentifier＆GT;
                            ＆LT; D​​IV ID =reportTitle级=reportTitle＆GT;
                                ＆LT;％＃的eval（标题）+：％＆GT;
                            ＆LT; / DIV＆GT;
                            ＆LT; D​​IV ID =reportFrequency级=reportFrequency＆GT;
                                ＆LT;％＃频率 - +的eval（Frequeny）％＆GT;
                            ＆LT; / DIV＆GT;
                        ＆LT; / DIV＆GT;

                        ＆LT; D​​IV CLASS =reportContent＆GT;
                            ＆LT; D​​IV CLASS =repeaterLine＆GT;
                                ＆LT; ASP：文本框ID =txtEmailRecipients=服务器级=文字编辑文字='＆LT;％＃的eval（收件人）％＆GT;文本模式=多行＆GT;＆LT; / ASP：文本框＆GT;
                            ＆LT; / DIV＆GT;
                        ＆LT; / DIV＆GT;



                        ＆LT; D​​IV ID =hiddenContent2＆GT;
                             ＆LT;％＃的eval（ReportID）％＆GT;
                        ＆LT; / DIV＆GT;


                    ＆LT; / ItemTemplate中＆GT;
                ＆LT; / ASP：直放站＆GT;
 

code

背后

 保护无效Save_Click（对象发件人，EventArgs的）
    {
        的foreach（在rptReports.Items的RepeaterItem项）
        {

            的foreach（在item.Controls控制C）
            {
                字符串的test1 = c.ID;
                类型t = c.GetType（）;
            }

            字符串的邮件=（（文本框）item.Controls [1]）的文本。
        }


    }
 

解决方案

试试这个，

 的foreach（在rptReports.Items的RepeaterItem项）
        {

    标签lblReportID =（标签）item.FindControl（lblReportID）;
     字符串ReportID = lblReportID.Text;
}
 

如果您使用的是分区，那么试试这个：

 ＆LT; D​​IV ID =hiddenContent2=服务器＆GT;
        ＆LT;％＃的eval（ReportID）％＆GT;
 ＆LT; / DIV＆GT;

 的foreach（在rptReports.Items的RepeaterItem项）
 {

        System.Web.UI.HtmlControls.HtmlGenericControl hiddenContent2 =（System.Web.UI.HtmlControls.HtmlGenericControl）item.FindControl（hiddenContent2）;
         字符串ReportID = hiddenContent2.InnerHtml;
 }
 

I have a repeater as shown below. How to get the Report ID in code behind (from the expression inside hiddenContent2) ?

The expression is

<%# Eval("ReportID") %>

Note: I prefer a method that does not use "FindControl".

ASP.NET

     <asp:Repeater ID="rptReports" runat="server">
                    <HeaderTemplate>
                        <div>
                        </div>
                    </HeaderTemplate>
                    <ItemTemplate>

                        <div id="repeaterIdentifier" class="repeaterIdentifier">
                            <div id="reportTitle" class="reportTitle">
                                <%# Eval("Title") +":" %>
                            </div>
                            <div id ="reportFrequency" class="reportFrequency">
                                <%# " Frequency - "+ Eval("Frequeny") %>
                            </div>
                        </div>

                        <div class="reportContent">
                            <div class="repeaterLine">
                                <asp:TextBox ID="txtEmailRecipients" runat="server" class="textEdit" Text='<%# Eval("Recipients")%>' TextMode="MultiLine"></asp:TextBox>
                            </div>
                        </div>



                        <div id="hiddenContent2"> 
                             <%# Eval("ReportID") %>
                        </div>


                    </ItemTemplate>
                </asp:Repeater>

Code Behind

    protected void Save_Click(object sender, EventArgs e)
    {
        foreach (RepeaterItem item in rptReports.Items)
        {

            foreach(Control c in item.Controls)
            {
                string test1 = c.ID;
                Type t = c.GetType();
            }

            string emails = ((TextBox)item.Controls[1]).Text;
        }


    }

解决方案

Try this,

 foreach (RepeaterItem item in rptReports.Items)
        {

    Label lblReportID= (Label)item.FindControl("lblReportID");
     string ReportID = lblReportID.Text;
}

If you are using "div", then try this:

 <div id="hiddenContent2" runat="server"> 
        <%# Eval("ReportID") %>
 </div>

 foreach (RepeaterItem item in rptReports.Items)
 {

        System.Web.UI.HtmlControls.HtmlGenericControl hiddenContent2 = (System.Web.UI.HtmlControls.HtmlGenericControl)item.FindControl("hiddenContent2");
         string ReportID = hiddenContent2.InnerHtml;
 }
