我有gridview根据两个事件从数据库中获取数据。第一个来自方法，第二个选择ddl.it工作得很好，我做了分页，当我浏览分页页面时我必须点击两次点击页面数量转到这个页面，所有页面都获得了相同的数据页面。所以任何人帮助我。

}
}
答案 0 :(得分：1)
在GridView1.PageIndex = e.NewPageIndex;致电GridView1.DataBind();
之后尝试重新绑定。
<强> - 编辑 -
DataSet，然后是DataBind（），尝试如下：
protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
BindGridFunction();
}
