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.

  • How to re-populate a multiple choice checkbox

    I have set up a checkbox in a UX component with multiple selections available.
    such as:

    [ ] red
    [X] blue
    [X] green
    [ ] yellow

    in the above scenario, I can save the results in a table field as a comma delineated string "blue","green"

    My Question
    For editing purposes, I want to take the saved comma delineated string and use it to re-populate the checkbox array with the previous choices.

    I have tried finding solutions in either client side js or xbasic. My tables are in .dbf form.

    I am not a programmer but understand basics. After searching for over 6 hours I realize I need help as I can't find an answer.

    can anybody point me in the right direction?

    I have attached a sample component and a very boring video.

    Hope this helps.

      Are you going to use a lookup filed to grab the data and then populate the new form?

        Hi Jay,

        I enjoyed your video and got a lot out of it. I may not have communicated my need well. I am saving the checkbox selection to a database file in the form of a character field with a comma delineated string. A day/week or whatever later, I would like to edit these choices and when a user selects the file, I want to bring up the same form with the same choices and populate it with the previous choices that were save. This will become the starting point for an edit to the choices where a user can add or remove checked items from the previous record.

        Thanks for the time you took and if this further clarification makes sense and you can provide any additional insight. I would be grateful.

          Lee, see above response. I think the answer is yes. I want to use previously saved data to repopulate the checkbox selection form from the saved data at any time after it is saved to the table.

            Re: How to re-populate a multiple choice checkbox

            I use this technique in my app.

            In the lookup definition
            Edit-combo field

            Everything else can be used in the fill-in fields except checkboxes because they are arrays.

            So in the Javascript\AfterSelect

            Read the array and put it into the new field.

            the field is A1000

            if(data.A1000 != null){
            var str = data.A1000;
            var addChoices = str.split(',');
            var addArray = [];
            for(var i = 0; i < addChoices.length; i++)
            addArray[i] = addChoices[i];

              Re: How to re-populate a multiple choice checkbox

              So are you saying that you want the same list to appear as the original list appeared, just with the items that were previously selected showing as selected again?
              If so, I think you may need to let us know how you are populating the table originally. You may need a separate table based with the items (or Choices as I called them) with what record it is associated, and a field to track whether it was selected during its last use.

              If that is the case, you need to add a logical field to the table, and let the selection (or lack thereof) populate the logical field.

                I gave this a go. No Joy. I created a form field called A1000 and populated it with "Blue","Green". When I ran this script I get the attached message.
