禁用PDF保存并打印按钮 [ ^ ]

您可以管理您的像这样的查询 -

选择txt_noticedesc，case isnull（txt_tcfile，''）当''然后''else'< a style =颜色：＃800000 href = docs /'+ replace（txt_tcfile，''，'％20'）+'target = _blank>查看< / a>'结束为来自M_tendernotices订单的txt_link txt_noticeno desc 

此处docs是文件夹名称，其中保存所有pdf文件

并将数据绑定到网格视图赞

 < ;   asp：TemplateField     HeaderText   = 链接 >  
 <   ItemTemplate  >  
 <   asp：标签    ID   =  Label1    ru nat   =  server   文本  ='  <％ #Eval（  txt_link）％> '   >  <   / asp：标签 >  
 
 
 <   / ItemTemplate   >  

Is there any way to open a pdf in the web application without allowing the user to save/downlaod the same ?

Disable PDF Save and Print Button[^]

You Can Manage Your Query Like this-

select  txt_noticedesc , case isnull(txt_tcfile,'') when '' then '' else '<a style=color: #800000 href=docs/'+ replace(txt_tcfile,' ','%20') +' target=_blank> View </a>' end as txt_link from  M_tendernotices order by txt_noticeno desc

Here docs is folder name where all pdf filed are saved
and Bind Data to Grid View Like

<asp:TemplateField HeaderText="Link">
    <ItemTemplate>
       <asp:Label ID="Label1" runat="server" Text='<%#Eval("txt_link") %>' ></asp:Label>
        

    </ItemTemplate>
