Answer 1

如楼上外加
必须把该GridView的KeyField设置为DataTable中对应的id的字段名字

Answer 2

还是运行不了啊 我给你们看代码
    protected void dgBulletinSys_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        objData = new Data();
        //获取UserId字段
        //string id = this.dgBulletinSys.Columns[0].AccessibleHeaderText.ToString();
        string id=this.dgBulletinSys.DataKeys[e.RowIndex].Value.ToString();
        objData.DeleteContent(id);
        this.ShowData();       
    }
    public void ShowData()
    {
        objData = new Data();
        ds = new DataSet();
        ds = objData.SelecALlData();    //获取所有的记录
        this.dgBulletinSys.DataSource = ds;
        this.dgBulletinSys.DataBind();
    }
