DataList用法+DataGrid分页的例子

DataList用法

//DataList套用table要放在外才行
<table>   
            <asp:DataList id="DataList1" style="Z-INDEX: 101; LEFT: 32px; POSITION: absolute; TOP: 144px"
                runat="server" Height="176px">           
          <headertemplate>
            <tr><td>A1</td><td>A2</td><td>A3</td><td>A4</td><td>A5</td><td>A6</td><td>A7</td><td>A8</td><td>修改</td><td>删除</td></tr>
          </headertemplate>         
          <itemtemplate>
          <tr>
            <td><%# DataBinder.(Container.DataItem,"A1") %></td>
            <td><%# DataBinder.(Container.DataItem,"A2") %></td>
            <td><%# DataBinder.(Container.DataItem,"A3") %></td>
            <td><%# DataBinder.(Container.DataItem,"A4") %></td>
            <td><%# DataBinder.(Container.DataItem,"A5") %></td>
            <td><%# DataBinder.(Container.DataItem,"A6") %></td>
            <td><%# DataBinder.(Container.DataItem,"A7") %></td>
            <td><%# DataBinder.(Container.DataItem,"A8") %></td>
            <td><a href='UpdateTable.aspx?id=<%# DataBinder.(Container.DataItem,"id") %>'  target="_blank"> 修改</a></td>
            <td><a href='WebForm1.aspx?id=<%# DataBinder.(Container.DataItem,"id") %>'> 删除</a></td>
           
          </tr></itemtemplate>         
            </asp:DataList>
            </table>
