Hello,
I am trying to open a txt file using a hyperlink. This link is in the gridview. My code is following

<Columns>
    <asp:BoundField DataField="file_name" HeaderText="File Name"/>

    <asp:TemplateField HeaderText="Open">

    <ItemTemplate>
    <asp:HyperLink ID="Open" NavigateUrl='<%#DataBinder.Eval(Container.DataItem , "file_name","C:\\folder1\\{0}") %>' Text='<%# Eval("file_name") %>' runat="server" />
    </ItemTemplate>
    </asp:TemplateField>

</Columns>


When I hover the mouse on the link it shows files///c:/folder1/file1.txt but really does not open anything.

Please can someone help me with this? What am I doin wrong?
Should I write any code behind?

Please this is urgrent.

Thanks

Hi there,

In order for a browser to download a file from the server, the file must be accessible by the server over http. A path like c:\Folder1 only makes sense in the context of the web server, not the client.

Move the file to the root of your site and then reference it as something like:

... NavigateUrl="~/SomeFile.txt" ...

Hope this helps,

Imar

Sorry, I wrongly posted my reply,

here is the original-
Thanks Imar for your reply.
Right now this program is running from my m/c and the files and folders are on my m/c but eventually this file will be on server and clients will be accessing this. Also, in the database field I do not have full path of the file location, that's the reason I am appending C:\....

I am sorry I did not understand what you mean by 'Move the file to the root of your site'?

Hi there,

No need to quote previous messages; the text is all here.

Anyway, not sure what you mean by m/c. Your server? With moving your files to the root, I meant to make them part of your site.

Let's say they page with the GridView is called Default.aspx. You access it like this (the actual address may vary):

http://localhost:3434/Default.aspx

Now, under the hood, Default.aspx exist on disk somewhere, at a location like c:\inetpub\wwwroot\default.aspx

The web server maps this physical address to ts virtual address. You need to do the same with your files: move them to c:\inetpub\wwwroot\ as well (or wherever your site is located) and address them like this:

http://localhost:3434/SomeFile.txt

Alternatively, look into Response.WriteFile: http://msdn.microsoft.com/en-us/libr...writefile.aspx

Hope this helps,

Imar
