VS 2008 / How To Limit Characters Per Line In Multiline Textbox
Dec 5, 2011
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.
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.
In my text area, I should be able to enter only 72 characters per line. If I use, cols property set to 72, it is allowing more or less number of characters depending on character width.
I have a multiline textbox which can contain only 500 characters. Now i want to show the user the number of characters left as they are typing into the textbox as is the case when we use twitter.
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
need to show only the LAST line. How can I do that? Here is part of my code...notice that I use Rows=1 on purpose so that I am able to show only 1 line but I need it to scroll all the way down and have it show only the last line of the whole content:
it's a multiline TextBox the MaxLength property does not work. At the moment I only see the option to use a CustomValidator with checking TextBox1.Text.Length on server side and perhaps in addition some Javascript client side validation.But isn't there a simpler way to do this, using the standard ASP.NET validators (RegularExpressionValidator, RangeValidator, CompareValidator, etc.)
How do I just get the first line of a multiline textbox? Either that or delete everything after "<br/>"? I tried something like this but it doesn't work:
In my asp web page, there is a multiline textbox. And upon a button click from the same page I need to delete the last row or line from the multiline textbox. How is that possible.
When I trace the variable while debugging I notice that when using Internet Explorer 7, the text is parsed correctly from the text box and <br /> tags are inserted appropriately.
However when the page is ran in Firefox or Chrome, the line breaks are not converted.
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 to display data from textarea the way it is been typed as ineg. hiiihello what are u doing I want to display the data typed in textarea shown above inside the panel the way it is typed.
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!!
How to prevent the new line character at the beginning of the text entering in a multiline text box? Now, I already trimmed the white space at the beginning of the text. but i can't prevent the new line character that has to be occurred by entering the enter key on the most beginning of the text box.
On my products page I have a small thumbnail and a description that is pulled from the database, since there is space restraints, how do I allow a max amount of characters, and if the description is longer append ... to the end? I'm using a data repeater and data binding for the content inside it.
i list the project descriptions on a field in my gridview, but some of them are too long. i want to limit them like 20 characters of 50 chars can be seen by the user. then pressing a button entire description will be displayed.
