Web Forms :: Server.HtmlEncode To All Controls?

Sep 23, 2010

I have used Server.HtmlEncode(MY TEXT) to display data,

I have setted the page property validateRequest="false" in .config file,

is there is any way to set the property some where and all the labels and text boxes automatically use Server.HtmlEncode() when i set there text

Mock Server.HtmlEncode - Returns Null Reference?

Nov 16, 2010

I'm trying to mock Server.HtmlEncode(), but I keep having a null reference exception.I'm pretty new to the Moq framework, here is my code:

var context = new Mock<HttpContextBase>();
var request = new Mock<HttpRequestBase>();
var response = new Mock<HttpResponseBase>();
var session = new Mock<HttpSessionStateBase>();
var server = new Mock<HttpServerUtilityBase>();
server.Setup(svr => svr.HtmlEncode(It.IsAny<string>())).Returns((string s) => s);
context.Setup(ctx => ctx.Request).Returns(request.Object);
context.Setup(ctx => ctx.Response).Returns(response.Object);
context.Setup(ctx => ctx.Session).Returns(session.Object);
context.Setup(ctx => ctx.Server).Returns(server.Object);

I've also tried the following:

context.Setup(ctx => ctx.Server.HtmlEncode(It.IsAny<string>())).Returns((string s) => s);

I've found a solution but it seems an outdated solution as expect is replaced with setup.

Web Forms :: Server.HtmlEncode Not Showing Or Decoding When Performing POST

Nov 9, 2010

I am trying to set up a POST from one aspx file to another progromatically. Inside the POST is a String of XML data which i have properly added to Server.HtmlEncode(). For some reason, when I grab it in my logs on the other page, it is showing with 3 question marks. I at first thought it was logging text i left somewhere, but have narrowed it down to a Encoding error of some sort because when i change the encoding it changes the character, and when I just put some text in there, i see it on the other side fine. i have tried UTF 8,UTF32,Unicode,ASCII... Can't seem to find the right combination. Can't find the UTF-16
when I use the Encoding object

Below is my Code:

[Code]....My Sending Debug log has the Extension xml coming out in HTML format correctly before POST. Below is just a piece of it[Code]....

And then on the other side log I get the below

Extensions =??

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?

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.

Forms Data Controls :: HTMLEncode In A Repeater?

Mar 6, 2011

I am using a nested repeater to display users popsts and replies to the posts. The posts can be two different types, just a comment, or a comment with statistics. To display the stats column, I am building the data in the SQL like:

[Code]....

This displays Ride Time as HH:MM. I am bolding the header (RT) with the <strong> embedded in theSQL. If I bind the result into a gridview, where I can turn the HTML Encode property = false, the RT is bolded. Is there a way to accomplish this in a repeater?

Allow Japanese Characters To Bypass C#s HtmlEncode Method?

Apr 4, 2011

I need to scrub data for malicious content in a form (whose website is UTF-8 encoded) so I'm doing the following:

myTextBox.Value = System.Web.HttpUtility.HtmlEncode(value); where value is the data to be placed in the TextBox.This does correctly scrub malicious data such as Javascript calls, but also turns Japanese characters into their UTF-8 equivalents, such as &#24859;

Is there a way to skip those characters from being encoded, like some sort of range?

Forms Data Controls :: Using Htmlencode On Detailsview And Gridview?

Feb 1, 2010

We are using gridview to display data and detailsview to show details, update, insert, and delete as needed. I am a bit confused on whether or not htmlencode and htmldecode is needed when storing data from detailsview. Gridviews always use boundfields and I think encoding and decoding is built in. For detailsview we use mostly templatefields (eval(), bind()), some boundfields, and some data is stored in codebehind using e.values[] or e.newvalues[].Here is where I've got the idea:http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.detailsview.itemupdated.aspxIf I use the iteration and htmlencode, detailsview read only mode displays decoded data. However, gridview displays encoded data and of course update mode of detailsview. So, it seems like detailsview using htmlencode and htmldecode somewhat, but I am not clear as to what degree and what would be the best way to handle it.

4.0 Framework Request Validation Will Not Allow Code-behind To Htmlencode Textboxes?

Jan 8, 2011

I have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.

This is the code I have so far.

Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text) [code]....

What can I do to make this work? According to all the websites I have visited it should work.
