注解

当属性 Mode 设置为 NextPreviousFirstLast 或 NextPrevious 值时，使用 PreviousPageImageUrl 该属性指定要为上一页按钮显示的图像的 URL。

备注

或者，可以通过设置 PreviousPageText 属性而不是 PreviousPageImageUrl 属性来显示上一页按钮的文本。 PreviousPageImageUrl如果同时设置了和PreviousPageText属性，则会显示PreviousPageText图像，该属性充当图像的备用文本。 在支持工具提示的浏览器中，此文本也显示为相应按钮的工具提示。

此属性的值存储在视图状态中。
