如何創建一個超鏈接字段進行SQL查詢

Question

在參考我的這個問題，

GridView Table 1 related to Table 2

我有一個GridView它看起來像這樣的時刻，

這是SQL fiddle

問題：

如何用FruitTitle創建HyperLinkField並鏈接到水果網站？

這是我使用的時刻顯示Types_of_Fruits_in_Crate的代碼和完美的作品，

  BoundField theField = new BoundField(); 
      theField.DataField = "Types_of_Fruits_in_Crate"; 
      gv.Columns.Add(theField); 

要放什麼

  HyperLinkField theField = new HyperLinkField(); 
      theField.DataTextField = 'Types_of_Fruits_in_Crate'; 
      theField.DataNavigateUrlFields = // not sure .... 

Answer 1

使用文字的控制，而不是超鏈接，然後嘗試使用以下查詢：

SELECT CrateTitle,CrateDescription,CrateID, 
stuff(
(
    SELECT '<a href=''' + [FruitWebsite] + ''' target=''_blank''>'+ [FruitTitle] +'</a>' 
    FROM fruits WHERE CrateID = t.CrateID FOR XML path('') 
),1,1,' ') Types_of_Fruits_in_Crate 
FROM (SELECT DISTINCT CrateTitle,CrateDescription,CrateID FROM fruits)t 

Answer 2

請嘗試像下面，它會幫助你...

SQL FIDDLE：http://www.sqlfiddle.com/#!3/96a49/18

SQL：

SELECT CrateTitle,CrateDescription,CrateID, 
stuff(
(
    SELECT ',<a href=''' + [FruitWebsite] + ''' target=''_blank''>'+ [FruitTitle] +'</a>' FROM fruits WHERE CrateID = t.CrateID FOR XML path('') 
),1,1,' ') Types_of_Fruits_in_Crate 
FROM (SELECT DISTINCT CrateTitle,CrateDescription,CrateID FROM fruits)t 

此外，添加HTML編碼=在你的代碼FALSE則只有HTML功能反映在您的網格視圖

C＃：

BoundField theField = new BoundField(); 
    theField.DataField = "Types_of_Fruits_in_Crate"; 
    theField.HtmlEncode = false; 
    gv.Columns.Add(theField);
