asp.net - ASP.NET 中的页面排序

Question

我尝试添加自定义分页，当我通过用户名和密码登录时，出现错误。
此外，我只显示他/她的文档，例如当 abc 登录时，abc 只能查看她的文档，但是当我添加自定义分页时，它显示UserID未提供错误，我还共享 sp 代码

代码是

protected void BindRepeater()
{
    SqlConnection con = new          
    SqlConnection(ConfigurationManager.ConnectionStrings["mydms"].
    ConnectionString.ToString());
    SqlCommand cmd = new SqlCommand("sphrdoc2", con);

    if (con.State == ConnectionState.Closed)
    {
        con.Open();
    }
    DataTable dt = new DataTable();
    SqlDataAdapter adp = new SqlDataAdapter(cmd);
    adp.Fill(dt);
    PagedDataSource pgitems = new PagedDataSource();
    DataView dv = new DataView(dt);

在这一行

 adp.Fill(dt);

发生错误

过程或函数“sphrdoc2”需要参数“@UserID”，但未提供该参数。

sp 是

ALTER procedure [dbo].[sphrdoc2]

    @UserID int
    as
    Select 
       dbo.DocumentInfo.DocID as DocumentID, 
       dbo.DocumentInfo.DocName as DocumentName, 

       dbo.DocType.DocType as Document, 

       dbo.Department.DepType as Department, 
       dbo.DocumentInfo.Uploadfile as FileUploaded,
       dbo.ApproveType.ApproveType AS Status 

       FROM 
       dbo.DocumentInfo
           inner JOIN dbo.DocType ON dbo.DocumentInfo.DocTypeID=dbo.DocType.DocTypeID
           inner JOIN dbo.Department ON dbo.DocumentInfo.DepID=dbo.Department.DepID
           left join dbo.ApproveType on dbo.DocumentInfo.ApproveID=dbo.ApproveType.ApproveID
       where UserID=@UserID

有人告诉我我在转发器代码中做错了什么吗？

您需要为您的存储过程传递参数。

  SqlCommand cmd = new SqlCommand("sphrdoc2", con);
  cmd.Parameters.AddWithValue("@UserID","YourUserID"); 
        if (con.State == ConnectionState.Closed)
        {
            con.Open();
        }
        DataTable dt = new DataTable();
        SqlDataAdapter adp = new SqlDataAdapter(cmd);
        adp.Fill(dt);
