How can I prevent the user from entering anything but alpha characters in my textbox?
Update Forgot to mention that its a dynmic control (created on the form when the user clicks a button).
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.
View 8 RepliesI'm looking at some site code on an XHTML doctype and from what I'm seeing the framework is ASP.net. The IDs in the HTML has a "$" in there. For example:
<img id="$ct100templateContent$SectionPanel1$ctl01$ctl02ctl00_templateContent_SectionPanel1_ctl01_ct999img" src="this.jpg"/>
From a W3C semantic point of view the "$" is not valid in an ID or Class. IDs and classes can only contain alpha numeric characters in an XHTML doctype.
Is the the "$" a ASP.net naming convention referencing a web control or template item?
I need to pull the first 2 alpha characters out of any data that is entered. What is the recommended best practice for this ?

View 1 RepliesI'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 have pages containing textbox controls into which names are typed. I need to be able to type Spanish characters like á ã é ũ Ñ ã ñ (I cut and pasted these from a Word document where they had been inserted as symbols). How can I enter these accented characters into textboxes using the keyboard?
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!!

View 1 RepliesI 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.
Do I need to use regex to ensure that the user has typed in English? All characters are valid except non English characters.

View 3 RepliesI'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.
how to limit the number of characters per line in a multiline textbox? Any posibility to do this with javascript? I have the users enter a list of names and need to limit each. I hate to use another textbox to add each name. If so, I would then add them to a listbox instead so they could select and remove a name.
