Question

在参考我的这个问题，

GridView Table 1 related to Table 2

我有一个GridView它看起来像这样的时刻，

这是SQL fiddle

问题：

如何用FruitTitle创建HyperLinkField并链接到水果网站？

这是我使用的时刻显示Types_of_Fruits_in_Crate的代码和完美的作品，

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

要放什么

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

Answer 1

使用文字的控制，而不是超链接，然后尝试使用以下查询：

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

请尝试像下面，它会帮助你...

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编码=在你的代码FALSE则只有HTML功能反映在您的网格视图

C＃：

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