Question

我有一个GridView表，数据源来自数据库。 GridView的第一列是一个复选框，复选框用户可以选中复选框。我不确定我哪里做错了，我的代码无法获得我勾选的复选框。

使用GridView

确保您只在page_load !IsPostBack绑定一次

if (!IsPostBack)
{
 BindGridView();
}

ViewStateMode="Disabled"

同时检查网页是否有ViewStateMode="Enabled"，而不是使用public ActionResult Index() { ViewBag.menuItem = "DashBoard"; return View(db.jobs.ToList()); }

启用它

asp.net失败从gridview复选框获取值
