Yet for some reason an ASP TextBox with the TextMode="MultiLine" allows inputs of characters outside of UTF-8. When I paste the following line of text into an ASP TextBox that is not MultiLine
the non UTF-8 characters are replaced, but not when I use a MultiLine TextBox.
EDIT: To explain a little more the set up I am seeing this problem in, here are 4 text areas that can be put on an ASP page.
I have a page in MVC where i want to take the email adddress as the input which can be of format like:"Jone Davi" <jone@gmail.com>, "Ben Miller" <ben@gmail.com>, "Jane Ton" <jane@gmail.com>,
Then from this I want to parse the valid emailaddress.But on click of the submit button getting error message" A potentially dangerous Request.Form value was detected from the client" Thus is there any way to take the input of email address in above format and bypass the security error for that specific page.
I have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.
When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.
I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?
Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...
I would like to make sure that everything that goes into my database is safe, i.e. protection from sql injection.
What I want to do is type something in a textbox, "<b>hello</b>" for example, it be encoded before it's put in the database, but when I retrieve it, I want it to display "hello" in bold.
I've tried the obvious of server.encode on input and server.decode on the output (to a label and a literal control), but couldn't get it to display the text in bold without having unencoded text in the database.
I am starting work on an already fully developed site. This site has no input encoding or output encoding. If some one ebters <input type="text"> in an insert form it is displayed as a real tex box when viewing that form details.
So how can i apply encoding at input or output to the WHOLE SITE?
turning on validate request is not an option as the cms wud need it off.
also this is .net 3.5 so no question od using <%: tags.
how to handle html and scriptswhat . if I build my own CMS? Isn't it inevitable that I'll want to store html code, possibly scripts, and almost certainly apostrophes and special characters, and then display them again.
What's the best way to do this, since I wont want to display the encoded html, but the html itself.
Would it be to encode everything then when I want to actually display the html, decode it, but everywhere else, keep it encoded?
I'm just trying to think of all the scenario's that I could come across when I accept user input where I don't know what they could be typing in. What if I WANT the user to be able to display html? Is it possible to decode only some tags but leave all other tags encoded?
When changing the textbox's text mode to multiline the textbox becomes resizable during runtime. I can't seem to find the property to disable this, does anyone know how I can resolve this issue?
I am using VS2010 and i am trying to block users typing alphabets and special charecters( allowed only numbers). ?I have written javascript and calling onkeydown and onkeyup events of my textbox. seems havascript doesn't firing up. am getting Uncaught ReferenceError javascript below is my user control code. Not sure why the javascript is not getting fired.
Since I'm new to coding and I'm trying to understand why here is a little more detail on the question.If you have a text box and you are limiting the input to say 2 charactrs do you really need to validate the input further? What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.
this works good when I am using it for a normal(singleline) textbox.But when i use this with Multiline textbox it does not work. I am using RegularExpressionValidator control of asp.net for the same.Would there be any way I can make it compatible with Multiline textbox?
This is for a multiline textbox on an asp.net site. I can use either a html control or a an asp.net control but what I want to do is somehow recognize which line is being clicked - preferably server-side so that it works without javascript but a jquery solution would be fine as well. After the line is clicked I need to take the text from said line, and return an output after a xml lookup.
I have a webform with a multiline textbox. In the code behind file I create a StringCollection & add some text. How can I assign the StringCollection to the multiline textbox?
I'm using VS 2010 and .net 4. I'm trying to figure out how to make a textbox be multiline and set the rows in codebehind.
I'm trying to figure it out for a user control that i'm working on. So in the properties passed through the to user control it will set the textbox to be a multiline or not.
i have one textbox with property TextMode="MultiLine"on my aspx page(C#)i entered data in that textbox & press enter to write next linebut while saving that multi line data in database it saves only single line data,it skips 2nd, 3rd, 4th.......... line.
I have written a web mailer that can send and receive emails and display them on a webpage.I have a problem displaying special characters though. Like Russian, and Greek and chinese.I am using openpop.net and I can get the encoding of the incoming email as one of my variables.Thing is, how do I display it? Do I set the content encoding of the whole page to what that specific email encoding is?I've got it UTF-8 at the moment and I get garbage.
In my web application I have a textbox called "Address" which is multiline and have 3 rows and 250 characters.
I am calling a javascript function in which i am calling AJAX to send the data to a webservice for some processing but AJAX is unable to process variable which contains multiline text.

On my Asp.Net GridView I am binding a textbox to a field in SQL. Sometimes the content of the textbox is more than 1 line and I
