需配置：Web.config文件

<system.web>
        <pages controlRenderingCompatibilityVersion="3.5" validateRequest="false" clientIDMode="AutoID" enableEventValidation="false" >
          <controls>
            <add tagPrefix="webdiyer" namespace="Wuqi.Webdiyer" assembly="AspNetPager" />
          </controls>
        </pages>
     </system.web>
