1. Add the Repeater control to the design page

2. Add a template to the <> source page

       <asp:repeater id="Repeater1 " runat="server">            <HeaderTemplate>                <ul>            </HeaderTemplate>            <ItemTemplate>                <li> <%# Eval ("Name")%></li>            </ItemTemplate>            < footertemplate>                </ul>            </FooterTemplate>        </asp:Repeater>

3. Binding data in a. cs file

            var query = context. Info;             = query;            Repeater1.databind ();

Repeater three ways to bind data in a template:

1. <%# Eval ("Property name or column name", "format")%>

    <%# Eval ("Birthday","{0:yyyy mm month DD day}")%>

2, <%# function name ()%>, function needs to be written in the. cs file beforehand and return a string. Such as:

     Public string Showsexname ()    {        bool sex = Convert.toboolean (Eval ("sex"));         return " male " " female " ;    }

3. If you are using an entity class (such as LINQ), you can extend the attribute to bind using <%# Eval ("extended attribute")%> in the template.

    <td><%# Eval ("nation1.name")%></td>
