注解

如果 ButtonType 属性设置为, ButtonType.Image 并且 ShowNextPageButton 属性设置为 true ,则使用 NextPageImageUrl 属性指定为下一页按钮显示的图像的 URL。When the ButtonType property is set to ButtonType.Image and the ShowNextPageButton property is set to true, use the NextPageImageUrl property to specify the URL to an image that is displayed for the next-page button. 此图像可以是在浏览器支持的任何文件格式 ( .jpg、.gif、.bmp 等) 。This image can be in any file format (.jpg, .gif, .bmp, and so on) that is supported in the browser.

如果将 ButtonType 属性设置为以外的值,则 ButtonType.Image 设置属性将 NextPageImageUrl 不起作用。When the ButtonType property is set to a value other than ButtonType.Image, setting the NextPageImageUrl property has no effect.

此属性的值存储在视图状态中。The value of this property is stored in viewstate.
