Question

我正在尝试使用存储过程填充GridView，但它不起作用，因为我没有看到错误。

以下是代码：

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        LoadGrid();
    }
}

private void LoadGrid()
{
    using (MathDBEntities1 db = new MathDBEntities1())
    {
        string name = Request.QueryString["qName"];
        string ID = (from tbl in db.checkQuizName(name) select tbl.QuizID).FirstOrDefault();
        GridView1.DataSource = db.QuestionsByQID(ID).ToList();
        GridView1.DataBind();
    }
}

存储过程代码

ALTER proc [dbo].[QuestionsByQID]
@quizID nvarchar
as begin
select * from dbo.Question where [QuizID] = @quizID
end

Answer 1

根据OP的评论

ALTER proc [dbo].[QuestionsByQID]
@quizID nvarchar(max)
as begin
select * from dbo.Question where [QuizID] = @quizID
end

当我尝试通过存储过程填充时，不会出现Gridview
