RE: FileUpload Control on Mobile FormAre you still focus on this issue? I've just got some new info. I've discussed with a DEV engineer who has ever worked on a similar issue, here is a workaround for mobile page to use the fileupload control. See the following comments ================================== The reason upload control can't work on mobile page is the result rendered by mobile page is lacking a form property: enctype="multipart/form-data". To inject this property you can inherit Html/Chtml/XhtmlMobileTextWriter class and override their WriteBeginTag method. The override method is something link below: public class ChtmlMobileMultipartTextWriter : System.Web.UI.MobileControls.Adapters.ChtmlMobileTextWriter { public ChtmlMobileMultipartTextWriter(System.IO.TextWriter writer, MobileCapabilities device) : base(writer, device) {} public override void WriteBeginTag(string tag) { if (tag == null) { throw new ArgumentNullException("tag"); } base.WriteBeginTag(tag); if (tag.Equals("form")) { WriteAttribute("enctype", "multipart/form-data"); } } } ============================== Hope this still helps.

Thanks for your posts, this will be helpful if I need to get it working on other mobile devices later. I have managed to get it working on a standard html based ASP.NET page for now. However, I have now noticed that the the file name part of the file path seams to be restricted to a maximum of 10 chars. I have tried adding the maxLength at a custom attribute but this does not seam to have any effect. Any ideas how I might be able to allow the user to submit longer file names ? Woodgnome. P.S. This is on the Windows Mobile 6 Classic Emulator. Show quote "Steven Cheng[MSFT]" wrote: > Hi Woodgnome, > > Does the further info in my last reply helps?

For the upload control, I haven't got any known of filename size limitation(at least not 10 chars). Does this problem only occur for your mobile devices? I've tested it on standard aspx page and PC boxes and I can submit long-filename files. Just use the below cose to printout the filename: >>>>>>>>>>>>>>>>> protected void Button1_Click(object sender, EventArgs e){ if (FileUpload1.HasFile) { Response.Write("<br/>filename: " + FileUpload1.FileName); } } >>>>>>>>>>>>>>>> Sincerely,Steven Cheng Microsoft MSDN Online Support Lead This posting is provided "AS IS" with no warranties, and confers no rights. -------------------- Show quote >Subject: RE: FileUpload Control on Mobile Form enctype="multipart/form-data".>Date: Thu, 13 Sep 2007 03:44:00 -0700 >Hi Steven, > >Thanks for your posts, this will be helpful if I need to get it working on >other mobile devices later. > >I have managed to get it working on a standard html based ASP.NET page for >now. > >However, I have now noticed that the the file name part of the file path >seams to be restricted to a maximum of 10 chars.

Thanks for the reply. It's just on the Windows Mobile 6 Classic Emulator. It works OK in a normal browser. The fileupload.HasFile property is set to false on postback. I am guessing that maxLength attribute on the rendered <input> tag is defaulting to 10 on the mobile device, but setting on rendering doesnt seam to have any effect. Woodgnome.

Since Steven is out of office for several days, I will continue work with you on this post. Let me first summarize the issue so far: you're now able to make the FileUpload work on mobile WebForm but the file name length is restricted to 10. Would you please send me a copy of your test web project along with detailed configuration (emulator, browser version) to me? I will try to reproduce the issue on my side and see if we could find the root cause. Thanks for the trouble. Regards, Walter Wang (waw***@online.microsoft.com, remove 'online.')

Hi Walter,
Thanks for the help. It's easy to reproduce just create a new web site, add a normal web page, add a file upload control and an asp link button and add the code suggested by Steven to the on click event of the link button. The emulator is the one include in the Windows Mobile 6 Professional SDK - Windows Mobile 6 Classic Emulator and the browser is the one included with the emulator. When the file name is greater than 10 chars no repsonse is returned because the fileuplad.HasFile property is set to false on postback. It works OK in IE on a normal desktop. I have included the code from the test site below : Thanks.

So you're not using MobileWebForm? I thought we're discussing FileUpload on MobileWebForm. If you're using mobile device to access the normal WebForm, I think many functions are not supported and the result is unexpected. Though I haven't find any document described this 10 characters length limit of uploaded file name. Regards, Walter Wang (waw***@online.microsoft.com, remove 'online.')
