I have a Silverlight application where I need to show a XML content in a TextBox or in a WebBrowser control, but this XML is stored compressed in database.
I found some tutorials and questions where people take the XML string, save it on temporary file then calls the Navigate method, passing this temporary file path. However, my application is Silverlight on client side, so I may have permissions problems storing temporary files on user's machine.
Showing the string in a TextBox it's an option, but the problem is that the XML content may be compressed,so it's difficult to read.
I know I can save this file on server, then deliver this file URL to my Silverlight application, then open a Browser window, but I'm just looking for a simple solution to do entirely on client side.
Is there some simple way to format(uncompress) this XML, or a simple way to open this string in WebBrowser as XML wihout saving a temporary file?

This is more of a general question about whether or not its actually possible to achieve what I want.
The basis is that my app allows the user to fill out various tables of data for a preventative maintenance check sheet. They can also attach images to this sheet which saves to the temporary storage on the IOS app. Once its complete they then press a button which generates a HTML document through a StreamWriter. Through this StreamWriter I have created, the images are also appended through URL references to the images in the temporary folder.
The HTML file (Generated Form) is then presented to the user using a WebView. Once the user has checked all the information, they then press a button which presents a MailViewController.
The HTML file (Generated Form) is then automatically attached and once the email has been entered you press send and everything works as it should.
The problem I am now having is that im not sure if its possible to keep the images in the html document. Once you open the HTML file on the receiving device, the images no longer loads because they no longer exist according to the HTML file.
So basically is it possible to keep the images in the HTML file once opened on the receiving device.
Sorry for the long description but its needed so you get an understanding of what I am actually doing. All the code I have written works as it should but just wanted to know if this is possible or not.
Thanks

Use base 64 encoded strings for the images and it should work. Since the images would be passed along with the html
I am working on a file uploading functionality using ASP.NET, C# and telerik. I am using telerik:RadAsyncUpload control. I already convert the file to byte array and save in the SQLServer Database.
On update page, I need to open file directly(from the binary data saved in db), when I will click a link. I need to Open that file in separate browser tab/window. I do not want to save file Physically on any local drive while retrieving it.
Please help me out.
What I have tried?
For time been, I am saving that binary data in a blank file located at some local drive and then attaching it to that link. but I do not want to save file Physically on any local drive while retrieving it. I want .....when user will click link binary data will directly flush on separate browser tab and he can view the file.
Create a handler (arbitrary one or an aspx page, whatever you find easier) that will read the database (e.g., based on a querystring argument) and return the appropriate response (via the Response object, e.g., Response.BinaryWrite()).
Note that you should set the appropriate headers and that depending on the type of file you return the browser may prompt the user to open/save it instead of opening it inline. You have some control over that via the content-disposition HTTP header, but it is ultimately up to the browser.
Also, you may want to use a RadWindow to open that handler to keep browser popups to a minimum to reduce the risk of them getting blocked by the browser.
I am working on a WPF project with C#.
There is a MainWindow and some other windows showing some data. I have also three XML files, where data from lists can be saved. The code is all written and works perfect.
Now my question is, how to save the whole file. I want to have the capability to, for example, save all the data into files, and user can open these files later and load the data into lists, and commence working, where they left the application before.
Can anybody help me?
If I understand your question correctly, you need to do it with following steps:
Save your XML files with a specific extension name.
you can achieve this by many ways: e.g. you can save your actual XML files into a location, and then just create a link file that contents links to these files. Or you can ZIP all the XML files into one single file.
link the default extension name to your application (so it will be opened by your application by default)
Open/read the file with XML content from your application.
Check this
Deserialize XML into items and display them in your list.
How do I open a PDF file List in dialog box in a new Window in an ASP.NET application ?
I want list of pdf file which is stored in folder in my application and then select any of pdf and save in logged user's particular folder.
Since you want to display a list of pdf files stored in a folder on the server side you will need to render the list to a page in some format that makes sense. You may open that up as a dialog (perhaps using something like jquery ui) but it wouldn't be necessary.
Next to each file you could have a button that indicates the action you are after, say 'Copy'.
This would then send the id/name of the relevant file to the server and the server code could copy the file to some other location on the server that you refer to as the users folder.
However, if you want to download the file to the user's machine that is something else and you will find many answer here on SO about that.
I am writing a website to consolidate a bunch of XML files with data into one MySQL database. I need to have a way to allow users to select a directory on their computer that contains a bunch of xml files. The site then reads each of those files and takes care of consolidating the information.
Is there a simple way (like the default open file dialog for win forms and wpf) to bring up a file dialog on a users computer, let the user pick a directory, and then be able to read the xml files in the selected directory? Would I have to upload them to the site temporarily first? Or could I just access them on the users computer?
Thanks!!
You can't access files from a webserver directly. You would need to write an ActiveX Control if you really don't find another way.
The standard conform way it just uploading one or more files with the browser fileupload:

I would suggest that the user should zip the files and just upload the zip file.
There are some hacks - but I don't think it fits:

http://dotnetslackers.com/articles/aspnet/Upload_multiple_files_using_the_HtmlInputFile_control.aspx
I think you have to have a web dialog to upload the files to a temp location like you already mentioned and do the consolidation there before committing to your database. Or, maybe you can do the consolidation in JavaScript in the user's browser instance.
