在邮件中发送中继器

Question

我需要在邮件中发送使用中继器获得的表，是否有关于如何在邮件正文中嵌入中继器的示例?我用MailMessage发送邮件。我试着实现这个例子:

    System.IO.StringWriter stringWrite = new System.IO.StringWriter();
    System.Web.UI.HtmlTextWriter htmlWrite =
    new HtmlTextWriter(stringWrite);
    MyRepeater.RenderControl(htmlWrite);
    string emailContent = stringWrite.ToString();

但是有一个错误:

Control ''m_repeater_btn" of type 'LinkButton' must be placed inside a form tag with    runat=server.

即使我把标签形式，我仍然得到一个错误，我应该怎么放?

这是我的asp.net页面

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true"   CodeBehind="ViewMySisters.aspx.cs"  %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <asp:Repeater ID="MyRepeater" runat="server">
    <HeaderTemplate>
        <table style="border-collapse:collapse; border:1px solid grey;" width="500">
            <tr>
                <td style="border: 1px solid grey;">firstname</td>
                <td style="border: 1px solid grey;">lastname</td>
                <td style="border: 1px solid grey;">age</td>
    <td style="border: 1px solid grey;">work experienes</td>
            </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
            <td style="border: 1px solid grey;"><%# DataBinder.Eval(Container.DataItem, "NAME")%></td>
            <td style="border: 1px solid grey;"><%# DataBinder.Eval(Container.DataItem, "FAMILY         NAME")%></td>
            <td style="border: 1px solid grey;"><%# DataBinder.Eval(Container.DataItem, "AGE")%></td>
            <td style="border: 1px solid grey;"><asp:LinkButton ID="btn" runat="server"   Text=">>>>" OnCommand="btnDetails_Command" CommandArgument='<%# Eval("ID") %>' /></td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater>
      <br />
<asp:Button ID="sendMail" runat="server" Text="send" OnClick="sendmail_Clicked" />
</asp:Content>

Answer 1

1)尝试执行您的页面(不是单个重复器):

    private string LoadMailTemplate()
    {
        var sb = new StringBuilder();
        using (var sw = new StringWriter(sb))
        {
            this.Server.Execute(this, sw, false);
        }
        return sb.ToString();
    }

其中this是您的页面类。

2)你也可以把你的中继器放在控制档上。下面是执行控件主体的代码:

 public static string LoadMailTemplate(string templatePath)      
 {
                var page = new Page();
                Control myControl = page.LoadControl(templatePath);   
                var sb = new StringBuilder();    
                page.Controls.Add(myControl);
                using (var sw = new StringWriter(sb))
                {
                    page.Server.Execute(page, sw, false);
                }
                return sb.ToString();
 }

调用:

string  emailBody = LoadMailTemplate("~/modules/eurolight/MailTemplates/OrderMailTemplate.ascx");

Answer 2

电子邮件不是asp.net页面。对您来说，这些控件仅限于平面HTML控件。我更改更改链接按钮为锚标记，并将其链接回您的web应用程序，并加载基于查询字符串的详细信息。

您需要以下代码:

Public Overrides Sub VerifyRenderingInServerForm(control As Control)
End Sub
