使用ModalPopupExtender＆amp;编辑GridView行值。在GridView中保存值

Question

我正在使用ModalPopUpExtender来显示GridView中项目的详细信息，我似乎无法使其工作，在从Popup编辑Row之后，它将返回到页面，它也将随着任何数据库访问而改变。

aspx表单

你可以像这样保存使用实体框架（示例代码）：

 protected void Save(object sender, EventArgs e)
{
    using (var context = new EntityModelNAme())
        {
            int Pid = Convert.ToInt32(Label13.Text);// Get your Primary Id value
            DBTableName Obj = (from c in context.DBTableName
                               where c.ID == Pid
                               select c).FirstOrDefault();// Match the Id with Database

            Obj.Type =  typetxt.Text;           
            Obj.Model = modeltxt.Text;
            Obj.Quant = quantxt.Text;
            // Like Above write your code
            context.SaveChanges();           
        }
        this.BindGrid();

}
