 <   div     class   =  column_w430 fl vl_divider >  
 
 < span class =code-keyword><   asp：ListView     ID   =  ListView1    runat   =  server     DataKeyField   = < span class =code-keyword> ID    
   
          < span class =code-attribute>                         DataSourceID   =  SqlDataSource1 >  
 
 <   ItemTemplate  >  
 <   table  >  
 <   tr  >  
 
 <   td    >  
 
 <   asp：ImageButton     ID   =  ImageButton1    runat   =  server  
   
            < span class =code-attribute>                                                              < span class =code-attribute>  高度  =  118px    
   
                                                                          < span class =code-attribute> ImageUrl   ='   <％ #Eval（  ImagePath）％>'   标题  ='  <％ #Eval（ 标题）％>'    
   
              < span class =code-attribute>                                                              宽度  =  170px    /  >  
 
 
 <   / td  >  
 
 
 <   / tr  >  
 <   / table  >  
 
 <   / ItemTemplate  >  
 <   / asp：ListView  >  
 
 <   / div  >  

< asp：SqlDataSource ID =SqlDataSource1runat =server

ConnectionString =<％$ ConnectionStrings：BOLKASHMIRConnectionString％>

SelectCommand =SELECT [ID]，[headlines]，[ImagePath] FROM [Taza_Treen] ORDER BY [ID]>

解决方案

< blockquote> ConnectionStrings：BOLKASHMIRConnectionString％>

SelectCommand =SELECT [ID]，[标题]，[ImagePath] FROM [Taza_Treen] ORDER BY [ID]>

在您的数据库中，您可以拥有图像的相对或绝对路径，例如

 http://yourdomain.com/images/example.png 
 
 images / example.png 

检查ImagePath列中的值，并确保它具有以太有效绝对路径或有效相对路径。

<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:BOLKASHMIRConnectionString %>"
SelectCommand="SELECT [ID], [headlines], [ImagePath] FROM [Taza_Treen] ORDER BY [ID]">

解决方案

ConnectionStrings:BOLKASHMIRConnectionString %>"
SelectCommand="SELECT [ID], [headlines], [ImagePath] FROM [Taza_Treen] ORDER BY [ID]">

In your database you can have relative or absolute path for the images, for example

http://yourdomain.com/images/example.png

images/example.png

check the value in ImagePath column and make sure it has ether valid absolute path or valid relative path.
