表不會顯示從頁面加載時填充

Question

我想填充page_load中的表，但沒有任何顯示，我知道我有來自數據庫的結果。這裏是我的代碼：

p

rotected void Page_Load(object sender, EventArgs e) 
     { 

      StreamReader reader = new StreamReader(Page.Request.InputStream); 
      data = reader.ReadToEnd(); 
      reader.Close(); 


      string queryKeys = ""; 
      if (data != "") 
      { 
       string[] IDs = data.TrimEnd().Split(' '); 
       SQLiteConnection sqlite_connectionUM = new SQLiteConnection("Data Source=" + path_to_um + ";Version=3;"); 

       sqlite_connectionUM.Open(); 
        foreach (string ID in IDs) 
        { 
       SQLiteCommand sqlite_queryMax = sqlite_connectionUM.CreateCommand(); 
       sqlite_queryMax.CommandText = "SELECT Keywords.Word from Keywords where Cluster = @c ORDER BY Keywords.Score LIMIT 5"; 
       sqlite_queryMax.Parameters.Add(new SQLiteParameter("@c", IDs[0])); 
       SQLiteDataReader keywords = sqlite_queryMax.ExecuteReader(); 
       while (keywords.Read()) 
       { 
        queryKeys += keywords.GetString(0) + " "; 
       } 

       showRecommendations(queryKeys); 
    } 
       queryKeys = ""; 
      } 

     } 

這是我showRecommendations方法：

public void showRecommendations(string data) 
     { 

      Recommendations recommendList = new Recommendations(); 
      List<string> similarUsers = new List<string>(); 
      List<RecommendedWebsites> recommendationList = new List<RecommendedWebsites>(); 


      recommendationList = recommendList.getRecommendations(data); 


      TableRow trow ; 
      TableCell tcell; 
      recommendedsites.Visible = true; 
      foreach (RecommendedWebsites recommendation in recommendationList) 
      { 
       Label1.Text = recommendation.getTitle(); 
       trow = new TableRow(); 

        tcell= new TableCell(); 
        tcell.Controls.Add(new LiteralControl("<b>" + recommendation.getTitle() + "</b>")); 
        trow.Cells.Add(tcell); 
        tcell.Controls.Add(new LiteralControl("<p> <a href=\"" + recommendation.getLink() + "\"</a>" + recommendation.getLink() + "</p>")); 
        trow.Cells.Add(tcell); 
      recommendedsites.Rows.Add(trow); 
      } 

     } 

爲什麼沒有顯示？我試圖用一個按鈕正常點擊，並表出現沒有任何問題

推薦網站一個asp.net數據控件（gridview或類似的東西）如果是，你可能想添加recommendedsites.DataBind （）;
