代码背后

protected void gvRef_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
      gvRef.PageIndex = e.NewPageIndex;
      LoadGridView();
      upd.Update();
}

首先，paging is not working不是澄清问题所在的最佳陈述。所以我假设你点击一个新的pageIndex - 没有（??）发生。

所以我尝试通过编写一个小型演示来解决您的问题。我创建了一个包含所有templateFields值的演示数据类。将这些值绑定到GridView和PageIndexChanged - 我将新索引绑定并重新绑定值。

}  

我遇到的唯一问题是我的web.config未正确配置。我错过了一些处理程序/模块aso。如果有一些脚本无法加载，您可能会在浏览器中检查您的开发控制台。

之后 - 它就像一个魅力。
