Mobiles :: Allow IPad User To Use Fileupload?
Feb 13, 2011
I'm using an image field in the EditTemplate of FormView to allow my users to upload an image. It works fine in all major browsers, including Safari. But not on the iPad. There I get the error message "object reference not set to an instance of an object" when the EditTemplate is submitted.
I'm guessing it's because, on the iPad, the FileUpload button in my EditTemplate is "greyed out" (which is a problem in and of itself)...I suppose there's no built-in way for an iPad user (using the iPad version of Safari) to search for an image on the iPad hard drive to upload (without a special App, I'm guessing)....So, when the EditTemplate form is submitting on an iPad, I get the above error message---I think because the Fileupload field is Null (I have this theory, because the stack trace references my "ValidateImage" method in my code behind.)Anybody have any direction or answers I should try? Is there an obvious answer here, or should I post my EditTemplate mark-up and code behind?

Not sure if this issue should be posed here, but i try anyway:I have a webpage with a button, button click the webpage will write an image (in binary) to the response object, resulting the user can open or save an image.
Code:
response.ClearHeaders();
response.ClearContent();
response.AddHeader("Content-Disposition", "attachment; filename=abc.jpg");
response.AddHeader("Content-Length", binaryImageFile.Length.ToString());
response.BinaryWrite(binaryImageFile);
response.Flush();
response.Close();
Everything is fine in IE in Windows, but in Safari in IPad/IPhone, it is viewed in a seperate browser tab, with the binary image file written as a very long string.In Windows, i know you have to select a program to use to open a new file type for the first time, is this the case in IPad? that i need to select a program?

I am developing an ASP.Net website which has a listbox which will be accessed by IPAD.The problem I am facing is that listbox has rather long text and IPAD does not show horizontal scrollbar when I use div tags. The two-finger horizontal scrolling doesn't work either on IPAD /Iphone.

I tried to use the asp.net fileupload control for uploading a picture or music file, from blackberry device to server. But, What happened is ; the file is uploaded , ie, the file is created with 0 bytes in it. That is, file is actually not uploaded. Since blackberry browser doesn't support other fileformats, the device contains only .png & .m4a fileformats in its samples. I have used these sample in blackberry for uploading. The same has occured in the case of .m4a files also... Why is it so...? One more thing... The blackberry browser which I am refering here is the blackberry browser simulator, bold 9700.

I have a .NET site and am looking to make it usable for iPad.
So far, I simply can't get the ASP.net login control to work on iPad. The user is never classed as logged in.
It's bizarre, if they enter the wrong details the login fails. If they enter the correct details it postsback and remains displying the anonymous content, not the logged-in content.
It works fine in Safari on a desktop, even if I use the 'develop' options to change the user agent to the iPad one. however, on iPad or iPad emulator I get the problem above.

I am in the middle of rebuilding a site an incorperating Ajax here and there.I was testing out the animations since I was interested in using them all over our new site.I was using the sample scripts found here:http://www.asp.net/ajax/videos/basic-aspnet-authentication-in-an-ajax-enabled-applicationplaced it on myserver and it works flawlessly across IE-Safari-Chrome-Mozilla. When I tried Ipad/Iphone the page tries to load, and then refreshes.I went to the samples page and found that everything there works EXCEPT the animations sample.http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/Animation/Animation.aspxIphone is Iphone 4 with latest updates, Ipad is original with latest updates.

Say that, there is a login.aspx page for any application. I would like to see this login page in different format if user visit by Iphone or any other mobile device. I have already designed two different page for test purposes. If i visit the page which is modified for Iphone, everything works fine.
what is the best way to switch between these two page depends on by which device user visit? These two pages could be even totally different two pages like black and white because of page layout issues.

Is it possible or easy to create a web page that allows users to drag and drop divs around the screen, and that this would work in a brwoser, whether that is on a PC, and iPhone, or an iPad?
My web page uses a few divs which contain some content, and the user is able to move these around as they wish.
It is currently created using ASP.NET DragPanelExtenders, but if they have to be abandoned, so be it.
To get this workign, will I have to create two versions of the page: one for PC based on mousemove events, and one for iPhone/iPad based on touch events?

My application allows a user to upload a file using the FileUpload control. The data contained in the uploaded file is then displayed to the user in a Grid for review if certain field validation criteria is met otherwise, a message is displayed stating that invalid data was encountered. If the data displayed is satisfactory, they have a 'Process Data' button to add the data to the system.
Initially, I used a simple If/Else block to determine if there was a file selected or not and if not, display a message to the user. As the coding got more complicated, this stopped working and I was told to use the RequiredFieldValidator control instead to get around the issues that arose.Now, I have a new issue: after the uploaded file data passes field criteria validation, the FileUpload box is cleared automatically and so when the user clicks the 'Process Data' button, the VC throws a message stating that the file name is missing from the FileUpload box.

wanted to know what is the easiest way to interface a mobile phone device with an online system. I have literally NO knowledge in this domain. However, I am brainstorming on possibility of an online application that will allow me to backup my data in nokia set 3110 such as my Address book in the application and restore it. This I want to achieve without connecting my phone to any PC. I am thinking on some way to achieve this by leveraging mobile phone line only. I beleive it may require my application to connect to mobile phone through mobile phone network. Currently my mobile phone line subscriber is offering Address Book backup/ restore service with some charge. I want to see if I can replicate similar features. I would really appreciate if you can give a direction to my random thoughts.If anything is not clear then please feel free to inquire. I look forward to your kind response.

Hopefully someone can give me some pointers to get this working properly.
I have a webpage which I would like the ability to upload files to be stored in a database. Here's the layout of the page:
[code]....
The update panel is configured as such:
ChildrenAsTriggers="True" EnableViewState="True" RenderMode="Block" UpdateMode="Always" Visible="True" Runat="Server"
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.

I need to upload a file (xml, pdf, etc) from the user's PC, but I need to write it directly to a file server. I cannot use FileUpload because there is no way to direct its initial upload to anything but the web server. So, how do I use the HTML INPUT to upload the file from the user's PC directly to a file server located at a different URL than the web server the web page is being hosted on?

I have a mobile selection list (see blow) that I had programmatically filled in from a generic collection of Status object (see below) which was retrieved from the database since I wanted to use the ID and Value stored in there to the selection list.
Mobile SelectionList Sample
[Code]....
Status Object model

Filled in a generic collection of Status object
[Code]....
Then, I tried to fill in the mobile selection list control using:
[Code]....
Now, when I tried to get the value of the selection list... it is giving me the same value as to what was stored in the text of the selection list. I tried using the following snippet:
[Code]....
or
[Code]....
Is there anyway I can get the value of the selection list that was retrieved from the database instead of the indexes?
