Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Easy Way To Force Word Wrap In Submitted Value From Textarea?

    Am I just missing something and there isn't an easy way to limit a submitted value from a textarea to a certain column width before a line break or what?

    On the subject, why doesn't the columns value in the textarea control properties actually work? You can set it to whatever you want but the width of the textarea never changes. Rows seems to work ok though.

    Anyway,
    Basically what I'd like to do is limit the column width to 80 and limit the max number of rows to 62 on my value that goes back to the server. I'll need some kind of line break character to search for to put the values into several different fields in a DB. I'm sure this can be done with JavaScript but I'm hoping there is an easier way. There certainly should be.

    If JavaScript is the only way good way to do this, does someone have a sample already made up that works both when typing and when something is pasted into the control?

    Text area column width settings do work so maybe you can show us a screenshot of your settings. However a text area does not word wrap at all in the sense you are intending. i.e., it will not auto insert a line feed unless you manually press return. If you want 80x62 you are probably intending to print this out and want it to fit on a single sheet of paper. You will then need to ensure your printer font is non-proportional. An ugly alternative is to have 62 text fields of length 80, but that is not pretty.

      I'm indeed already working with an "Ugly Alternative" because the backend that I'm connecting to is exactly what you described. This is a legacy DB that still needs to be able to be updated from it's old program. I'm trying to use Alpha as a user friendly UI for that backend of 62 text fields that are 80 in length.

      As for the column width settings not working, I can give you a screen shot but I'm not sure it'll help because I can start a blank UX, put a textarea field in it, and put in the number of columns and it doesn't work right off the bat. Really easy to replicate. The Width attribute under "Field Properties" works as far as setting a value like 6in. The Columns attribute under "TextArea Properties" does absolutely nothing.

        I ran across the "WORD_WRAP()" xBasic function the other day that might be of help here if you want to programmatically wrap a long string of text.

          Oh yes - column setting on a grid controls width, on a UX you need to set the Width property, like =400px.

          But again, not going to help with your word wrap. I would suggest looking at www.ckeditor.com to see if they have a plugin for fixed width 80 column entry that also hyphenates. It would produce HTML and you would have to render that back to plain text (somehow).

            dialog column and row numbers will be ignored if the dialog is set to container width, is this the settings you have? if you change to control width then they should work.
            again the crlf() is not inserted as far as I know.
            thanks for reading

              Thanks Rich!
              That will probably work for now until I come up with a more elegant solution.
              I just have to escape it for javascript and then replace the crlfs given by the word_wrap command with '\n' that javascript wants.

              Code:
              function TestText as c (e as p)
              	debug(1)
              dim jscmd as c	
              dim newVal as c
              
              newVal = word_wrap(e._currentRowDataNew.TEXTAREA1,8)
              
              newVal = strtran(js_escape(newVal),crlf(),"\n")
              
              jscmd = "{dialog.Object}.setValue('textarea1','"+newVal+"');"
              
              TestText = jscmd
              
              end function
              I'd love to take care of it all client-side and I'm still working on a JavaScript only solution but this is cool for now.

              Steve,
              Thanks for the link, I'll check it out.

              Gandhi,
              Nope, I'm set to control width. Rows work but columns do not.
