asp.net学习之Repeater控件

原文:asp.net学习之Repeater控件 Repeater控件和DataList控件，可以用来一次显示一组数据项。比如，可以用它们显示一个数据表中的所有行。
Repeater控件完全由模板驱动，提供了最大的灵活性，可以任意设置它的输出格式。DataList控件也由模板驱动，和Repeater不同的是，DataList默认输出是HTML表格，DataList将数据源中的记录输出为HTML表格一个个的单元格。

1. Repeater控件显示数据

要使用Repeater控件显示数据，必须创建ItemTemplate。如下所示：
例1：使用ItemTemplate显示数据

<asp:Repeater id="rptMovies" DataSourceID="srcMovies" Runat="server"
OnItemCommand="rptMovies_ItemCommand" OnItemDataBound="rptMovies_ItemDataBound" OnDataBinding="rptMovies_DataBinding">
<HeaderTemplate>
<table class="movies">
<tr> <th>Title</th><th>Director</th><th>In Theaters</th> </tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td><asp:TextBox id="txtTitle" Text='<%#Eval("Title")%>' Runat="server" /></td>
<td><asp:TextBox id="txtDirector" Text='<%#Eval("Director")%>' Runat="server" /></td>
<td><asp:CheckBox id="chkInTheaters" Checked='<%#Eval("InTheaters")%>'Runat="server" /></td>
<td><asp:LinkButton id="lnkUpdate" CommandName="Update" Text="Update" Runat="server" />
 | <asp:LinkButton id="lnkDelete" CommandName="Delete" Text="Delete"
OnClientClick="return confirm(‘Are you sure?');" Runat="server" /></td>
</tr>
</ItemTemplate>
<FooterTemplate>
<tr>
<td><asp:TextBox id="txtTitle" Runat="server" /></td>
<td><asp:TextBox id="txtDirector" Runat="server" /></td>
<td><asp:CheckBox id="chkInTheaters" Runat="server" /></td>
<td><asp:LinkButton id="lnkInsert" CommandName="Insert" Text="Insert" Runat="server" /></td>
</tr>
</table>
</FooterTemplate>
</asp:Repeater>

<asp:SqlDataSource id="srcMovies" ConnectionString="<%$ ConnectionStrings:Movies %>"
SelectCommand="SELECT Id,Title,Director,InTheaters FROM Movies"
UpdateCommand="UPDATE Movies SET Title=@Title,Director=@Director,InTheaters=@InTheaters WHERE Id=@Id"
InsertCommand="INSERT Movies(Title,Director,InTheaters) VALUES(@Title,@Director,@InTheaters)"
DeleteCommand="DELETE Movies WHERE Id=@Id" Runat="server">
<UpdateParameters>
<asp:Parameter Name="Id" />
<asp:Parameter Name="Title" />
<asp:Parameter Name="Director" />
<asp:Parameter Name="InTheaters" />
</UpdateParameters>
<InsertParameters>
<asp:Parameter Name="Title" />
<asp:Parameter Name="Director" />
<asp:Parameter Name="InTheaters" />
</InsertParameters>
<DeleteParameters>
