HttpUtility.HtmlDecode Cannot Decode ASCII Greater Than 127?

Oct 22, 2010

I have a list of character that display fine in WebBrowser in the form of encoded characters such as � ... But when posting these characters onto server to I realized that HttpUtility.HtmlDecode cannot convert them to characters as browser did, they all become space.

text = System.Web.HttpUtility.HtmlDecode("");

I expect it to return € but it return space instead. The same thing happen for some other characters as well.

MVC :: HttpUtility.Decode Does Not Work In TextBox Or TextArea?

Jul 17, 2010

I am trying to render html encoded string that is stored in SQL Server into human readable form. The HttpUtility.Decode does not decode the text that is rendered in between the open tag and closing tag of any input tag (ie. TextBox or TextArea or Select) in my ASPX page. However, HttpUtility.Decode works fine if the text is not in an input tag. The following is my test code. For example, the value of AdmitDX field in database is "Someone's comment" which is "Someone's comment" when decoded. The first two code nuggets <%%> will show as "Someone's comment" and the thrid code nugget will show "Someone's comment".

<!-- the following two lines have html encoded text, instead of html decoded text -->
<%= Html.TextArea("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX))%>
<%= Html.TextBox("AdmitDX", HttpUtility.HtmlDecode(thisTransfer.AdmitDX)) %>
<!-- the next line works fine -->
Test = <%= HttpUtility.HtmlDecode(thisTransfer.AdmitDX) %>

C# - HTMLencode HTMLdecode?

Apr 16, 2010

I have a text area and I want to store the text entered by user in database with html formatting like paragraph break, numbered list. I am using HTMLencode and HTMLdecode for this.Sample of my code is like this:

string str1 = Server.HtmlEncode(TextBox1.Text);
Response.Write(Server.HtmlDecode(str1));

If user entered text with 2 paragraphs, str1 shows characters between paragraphs. but when it writes it to screen, just append 2nd paragraph with 1st. While I'm decoding it, why doesn't it print 2 paragraphs?

HTMLDecode In A Object DataSource?

I have written a tiered application for a mate of mine to store and manage his massive CD collection. When I save the Album name I HTMLEnchode the input. I then use a drop down list on another page that pulls back all the Albums liked to a Specific artist but when i get the data back from my Object data source the data is still enchoded. At what point do i need to decode the data? Is it right at the begining in the DAL or in the actual drop down list.

Security :: Mitigate The XSS / HTMLEncode And HTMLDecode?

Oct 6, 2010

Trying to protect against XSS on a CMS I'm working and I therefore encode all necessary client input but on retrieval from DB, I'm getting all these funny HTML characters displayed on the HTML Page as a result of the encoding.

I'm considering appending a decode on retrieval but I'm wondering what the point of the inital encoding is if I decode eventually.

Please how do I effectively mitigate the XSS issue using the encode/decode avenue.

Web Forms :: HtmlEncode() And HtmlDecode() Not Working Correctly?

Dec 20, 2010

I have a url which I wish to encode that contains a couple of encrypted querystring parameters:

[URL]

I've been asked by a client I'm working with to html encode this url. I've used HttpUtility.HtmlEncode() to do this. This returned the following:

[URL]

This appears to be correct as the '&' has been replaced with '&'. However a problem arises when I try to use HttpUtility.HtmlDecode() on this new value as I get the following returned:

[URL]

What appears to have occurred is the '&' has had the 'amp' removed and the ';' has been html encoded (I checked the value of '%3b' and it corresponds with the html encoded value of a semi-colon). I'm not sure why this is happening?

I realise I could manually do a .Replace("%3b", "") as a temporary fix but I can't see this being a good long-term solution.

Manually Converting Between ASCII And Net Characters?

Feb 5, 2010

I am working on writing some code to scrub user input to my ASP.NET site. I need to scrub input to remove all references to ASCII characters 145, 146, 147, 148 which are occasionally getting input from my mac users who are copying and pasting content they write in a word processor on their macs.

My issue is the following three strings I am led to believe should output the same text.

string test1 = Convert.ToChar(147).ToString();
string test2 = String.Format("'{0}'", Convert.ToChar(147));
char[] characters = System.Text.Encoding.ASCII.GetChars(new byte[] { 147 });
string test3 = new string(characters);

Yet when I set an ASP TextBox to equal the following

txtShowValues.Text = test1 + "*" + test2 + "*" + test3;

I get a blank value for test1, test2 works correctly, and test3 outputs as a '?'.

Can someone explain what is happening differently. I am hoping this will help me understand how .NET is using ASCII values for characters over 128 so that I can write a good scrubbing script.

EDIT
The values I mentioned (145 - 148) are curly quotes. So single left, single right, double left, double right.

By "works correctly" I mean it outputs a curly quote to my browser.

SECOND EDIT
The following code (mentioned in an answer) outputs the curly quotes as well. So maybe the problem was using ASCII in test 3.

char[] characters2 = System.Text.Encoding.Default.GetChars(new byte[] { 147 });
string test4 = new string(characters2);

THIRD EDIT
I found a mac that I could borrow and was able to duplicate the problem. When I copy and paste text that has quote symbols in them from Word into my web app on the mac it pastes curly quotes (147 and 148). When I hit save curly quotes are saved to the database, so I will use the code you all helped me with to scrub that content.

FOUTH EDIT
Spent some time writing more sample code based on the responses here and noticed it has something to do with MultiLine TextBoxes in ASP.NET. There was good info here, so I decided to just start a new question: http://stackoverflow.com/questions/2215547/asp-net-multiline-textbox-allowing-input-above-utf-8

AJAX :: Server.HTMLDecode Works But Modal Popup Doesn't Close

As the title of this post already mentioned, I'm using a modal popup window to edit rows in the gridview. One column in the gridview contains an URL code. When I fire the edit button a popup opens and show the URL in a textbox in this format: [URL]

When I am using the Server.HTMLDecode function, the modal popup doesn't close anymore.

I am using the following code:

[Code]....

The funny thing is, when I change it to: txtURL.Text = row.Cells[3].Text; then I can close the modal popup, but unfortunately it is not decoded.
