I was using asp:hyperlink control to show links to local LAN files , e.g.
<asp:HyperLink ID="lnkToClick" runat="server">link to LAN fileasp:HyperLink>
Me.lnkToClick.NavigateUrl = “file://\\Server\Folder\FileName.ext“
It worked fine, unless Folder path or filename has spaces in it(Probably other special character could cause the same problem). In this case, generated html file has %20 instead of space and clicking on the generated link in IE doesn't open file.
In othe words Internet Explorer 6. doesn't open the following link
file://\\database\docs\sally\staff' _fcksavedurl='file://\\Server\Folder\TWO%20WORDS.doc">file://\\database\docs\sally\staff'>file://\\Server\Folder\TWO%20WORDS.doc">file://\\Server\Folder\TWO WORDS.doc
After some investigation with Reflector I found that HyperLink calls AddAttributesToRender, which calls ResolveClientUrl, which in turn calls HttpUtility.UrlPathEncode. And there is no simple way to exclude encoding for “file://“ paths.
There is ASP.NET 2.0 asp:hyperlink control bug, the control worked correctly in ASP.NET 1.1 .
However ther is a simple alternative -use A control instead of HyperLink.
<a ID="lnkToClick" runat="server">link to LAN file</a>
Me.lnkToClick.href = “file://\\Server\Folder\FileName.ext“
The similar problem is reported to MS here.
One reader of the post asked how to replace
<asp:HyperLink runat="server" Target="_blank" Text="<img src=pdficon_small.gif border=0 align=absmiddle alt='Load PDF File'>" NavigateUrl='<%# DataBinder.Eval(Container, "DataItem.FilePath") %>'>
My suggestion was:
<a runat="server" target="_blank" href='<%# DataBinder.Eval(Container, "DataItem.FilePath") %>'>
<img src=pdficon_small.gif border=0 align=absmiddle alt='Load PDF File'>
