“System.Web.UI.WebControls.DataControlField”不包含“OptionsColumn”的定义，并且找不到可接受类型为“System.Web.UI.WebControls.DataControlField”的第一个参数的扩展方法“OptionsColumn”(是否缺少 using 指令或程序集引用?)
代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class caiwu_jinjirenxinzichakan : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
this.GridView1.Columns[3].OptionsColumn.AllowEdit = false;
}
protected void Button1_Click(object sender, EventArgs e)
{
}
}
