It并不是你想要的，但你的问题当然可以有你自己的逻辑......并且从给定的链接中得到参考!!



Goog Luck！

您可以在gridview的itemtemplate中包含图像控件。然后在imageUrl属性中，您可以调用如下函数：

 <   asp：image     id   =  myImage    runat   =  server    imageurl   =  < ％ #SetImageUrl（  DataBaseCondition）％>    /  >  

现在在你的代码后面实现SetImageUrl（string _databaseCondition）函数来se图像的网址。

您好，

您必须在DataBase结束处理它。

 选择 t.Id，t.Name， CASE   WHEN 标志=真然后 ' 〜/ Images / true.png'  ELSE  ' 〜/ Images / false.png'  END  来自 表 t 

I want to change the image in gridview .

When the conditions in database are satisfied, then the column is true, otherwise false.
and m fetching image for true and false...
then how can i do this in asp.net using sql???

It''s not that you''re looking for, but you can certainly have your own logic for your question.. And have a reference from given link !!

Goog Luck !

You can include an image control in itemtemplate of gridview. Then in the imageUrl property you can call a function like:

<asp:image id="myImage" runat="server" imageurl="<%#SetImageUrl("DataBaseCondition")%>" />

Now in your code behind implement SetImageUrl(string _databaseCondition) function to set the url of the image.

Hi,
you must handle it at DataBase end.

Select t.Id, t.Name, CASE WHEN Flag = true THEN '~/Images/true.png' ELSE '~/Images/false.png' END from Table t
