为什么要执行所有这些操作，然后评论并尝试.每次加载数据集都会自动将其设置为第1页.

如果存在问题，请逐行调试它，并查看ig值是否已返回并已绑定.此外，将datagrid Itemdatabound放置在页面中以检查Databind事件.

Why are you doing all these, comment and try. Every load of dataset will automatically set it to page 1.

If issue exists, Debug it line by line and see ig values are returned back and binded or not. Further, Place datagrid Itemdatabound in your page to check the Databind event.
