How To Prevent Tab Characters From Being Pasted Into A Textbox
Dec 24, 2010
I'd like to have an asp.net textbox that people can paste content into and it works like notepad, i.e. no formatting or special characters will get entered. I take text and pass it to a web service which manipulates it and converts it into a tab delimited file. The problem I've experienced is sometimes people copy from MS Word and paste that content in and somehow even the tab characters etc. get passed to the web service. I run routines now to strip that information out but it would be so much easier if the textbox on the web page didn't capture anything but the text itself, i.e. visible characters (numbers, letters, punctuation).

I want to prevent the entry of two characters together but I want the user to be able to enter one or the other as well as use the enter key. I would like to use a white list instead of black listing characters. The regular expression also needs to support a min and max length. I'm doing client side validation using the asp:regularexpression control. I do not want to have to do server side validation unless that's the only solution to this problem. Has anyone else run into this?
Here is the regex I'm currently using:
(?!.(&#))^[a-zA-Z0-9!@#$%^&_=+~''"";:,
.()?-]{1,1000}$
I'm using a asp.net textbox that is set to multiline so I have to allow for
and or what's the point of using a multiline textbox :)
I want to keep the user from entering &# together but allow them to enter text with & or # in it and allow all of the characters a-zA-Z0-9!@#$%^&*_=+~''"";:,
.()?-.
A valid text entry would be as follows:
I have a question about my order. The order number is 12345.
An invalid text entry would be as follows:
I am trying to keep the user from entering &# in the textbox, but I want to allow them to enter & or #.

The first step to reproduce the behaviour is pasting a specifc text from a PDF document into the HTMLEditor:
After that, select the text:
And then, click the Justify button. The selected text simply disappears:
The HTML code generated by the content:
The same happens for other texts like (also pasted from the same PDF):
The correspondig HTML markup generated by the HTMLEditor:
It seems like HTMLEditor has problems with some characters like " or subscripts. If the same texts are pasted into Word and then copied into the HTMLEditor, it works ok and the text is justified correctly.

I have a client who needs to paste sections of Word documents into my SQL Server 2005 database. There are paragraphs and bullet points within the text that has to all go into the same field. When I copy and paste the text straight from Word the bullet points are displayed as dots but not as a list, i.e. the text is wrapped continuously and the formatting is lost. I have built a web front end in ASP.NET 2.0 using formviews for data display, editing and entering. If I use a Access backend the text will display correctly if the bullets are replaced with <li> tags - a bit tedious for the user of course. In SQL server I am getting a security warning that stops any HTML code to be pasted into a field. I thought of using stylesheets but even this is difficult.

On my current form I have it validating a Canadian Postal Address (xxx xxx). The space is optional but if the user does not use a space, then once the validation passes it will insert one. How can I count the first 3 characters of the textbox, insert a space, then add the rest of the characters?

How to write French accent characters such as - é - in ASP/HTML text box? I can copy and paste it in the text box like I did now - so there is nothing wrong with the encoding - but the problem is how to type it (write it!). I also know that é in HTML mean é but cant know how this may help.

I'm sure this will need to use javascript but not sure exactly how to do it. I need to count the characters typed in a textbox and when it reaches 10 I want a sub to be called in the code. Or have it click a button on the screen which is probably easier. How to do this? I would think I would call the script with the OnTextChanged? And in the script use the .length property to see if it is 10? Maybe I just answered my question here!!

I am using Multi-line Textbox through which users will be able to enter data which will be saved on to the SQL Server 2008 database. There is an other process, which reads this data from the table and writes to a text file.
Problem:
If the data entered by users in text box contains <Enter> from keyboard, it is saving to the database with some spaces replacing the <Enter>.
Some how if I read the same data to a text box on webpage, it is being displayed properly.
But, if my second process that reads the data from database and prints to a text file, it is not keeping the text format properly. It is not retaining the <Enter> in the data being printed to text file.

how can I allow only alpha characters into a dynamically created textbox? I don't think I can use a regular expression validator for this issue. Unfortunately, I cannot use Ajax for this issue either.

I've had an "interesting" request .
1) Is it possible, in a multiline textbox, to automatically break to the next line after 100 characters?
2) If not, is it possible to parse the enter key as entered by the user to break the line in the code behind?
Some additional info:
The person requesting this does not think that the user should use a single line textbox limited to 100 characters and click an "Add Line" button to store that field in a table.
The person requesting this is of the belief that a DEC Alpha-based system that currently does this can be replicated on the web.
