C# - How To Parse User Input From A Textarea Line By Line
Apr 19, 2010
If I have a variable that contains text information (say taken from a textarea), how can I read the text content held in a string variable line by line?
The text entered in the text area will have (enter key) to separate the line.
I'm working with an MVC1.0 web app and I've found a bit of an odd anomaly.
I have a search box on the first page (normal text box) and the input from this is passed through to the ViewData and on to the second page.
On the second page, I render a TextArea with this search input text from the ViewData.
Eg:
[Code]....
The problem is, there is an extra line break in the TextArea, just above the original text.
Stranger still is that if I now submit this page and the view is reloaded (after validation fails) - the original string of text has been trimmed and has no line breaks, but the TextArea now has 2 line breaks above the original text.
This can be repeated - every time the page reloads it has another line break.
It's driving me insane - does anyone have an idea on how to fix this?
FYI, you can check it out yourself - on your mobile phone, browse to [URL], punch something in the search box and hit search. You'll notice one line break added the first time the page loads. Then just hit "Find Best Offer" without entering a budget or selecting a category, and you'll see what I mean about the additional line breaks.
Is there something fairly simple, even with javascript, to replace a line break in a text area with a <br /> when it gets submitted to a database? Right now I have a button that just will add in the tag to do it, but I'd much rather have it be automated to make the user less hassled to put that in themsevles. That, and it would make things just that much faster.
Even if there was something to put each section in a <p> tag, but that's not entirely necessary, the <br /> seems like it would be the easier method.
I'm using MS SQL server and c# if that makes a difference.

I insert a text box, change the parameters to multi line and then pass the string to sql. Users insert comments etc, using line breaks, however because I just pass this as a string the line breaks are not there when they view the text box after input. Example: Here is a well formatted comment. as I typed in the text box today. Inserted in to sql as a string, returns this on select:

ave never used ajax.... I'm currently putting together a little web app that basically calls a program on the server itself (a command line tool) and displays the output to the web page.When the command line tool is run from the command line, it outputs status messages as it does it's thing... as it is now, my page just displays all the output when it's done. What I would like to do is show each line of output on the web page as they happen, just like when run from the command line. I'm guessing ajax is what I need... can anyone point me in the right direction for this specific scenario (user clicks button, output streams to web page as it happens without full page post backs)... a good example would be how ping.exe displays it's output on the command line
I'm using MVC, and i'm building my own basic blogging engine. I need to be able to allow HTML input to be submitted to the server so it can be added to a database. I only want HTML input allowed in that textarea alone, but I still want my other validation like StringLength etc. How could I do this?
