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.

    Cascade choices from dropdown to a checkbox

    I have a table that list body models along with available options.

    On the entry screen I want a dropdown for bodymodel, and then have it populate a checkbox control with only the options that match with the body model.

    I've done cascading drop downs and that is easy enough, but checkbox doesn't have a cascade options.

    From the Help menu, access Videos, and search for populating.

    You'll find D52, among other, that describe how to dynamically populate checkbox controls.

    So, based on a dropdown box selection, you'll be able to build your checkbox control.

      I watched the video. It looks a lot more complicated than cascading choices to a drop down. And the video was showing updates from something entered on the dialog. So I will have to do the lookups by hand.

        You are right. The Checkbox control doesn't have an option to dynamically update the list based on the value of another field, so you would have to do it manually.

          Here is the error message I get.
          Error executing Ajax callback function 'fixcheckbox' Error reported was: command: choices=e.dataSubmitted.Newchoices Property not found
          e.dataSubmitted subelement not found.

          and here is my xbasic code.

          function fixcheckbox as C(e as p)
          choices=e.dataSubmitted.Newchoices
          choices=comma_to_crlf(choices)

          dim html as c
          html=a5w_checkboxes(choices,"GRID1.V.R-1.OPTIONS","","","","","(dialog.componetname).GRID1.V.R-1.OPTIONS")

          dim id as c
          id="(dialog.componetname).GRID1.V.R-1.OPTIONS"

          dim js as c
          js="$('"+id+"').innerHTML = '"+js_escape(html)+"';"

          fixcheckbox=js

          end function

          What do you think I am missing?

            Datasubmitted is really only available after you have hit submit on server side events.

            In an xbasic function, you have to get there through the e. variables, which I think is the case with what you are doing.

            But I'd need more information about how this is setup to help much more than that.

            Is it a grid or UX?

            How are the fields setup?

            How is the newchoices control setup and populated?

              It is a grid, dbf. newchoices is a hidden text box, filled with look up and fill in fields in the on change of the drop down. I tested with newchoices unhidden, and it does put each of the choices in the box with a comma between each. newchoices is a calculated field setup with the grid newchoices=""

                Try

                e._currentRowDataNew.choices

                instead of datasubmitted.
