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.

  • Dynamic template

    Hi Everyone,

    I am new and had been focusing on the SIMPLE-LIST-CONTROL
    to utilize , DYNAMIC-TEMPLATE to display the results.

    Its unfortunate, I found very limited example or video.
    or perhaps its so simple that I had missed.

    Enclosed a very simple example ..

    with two group of LISTS control./

    group one using the basic ..
    layout type = Column

    Group two using
    layout type = freedom
    where i need help to find a way to dynamically
    coded it so that the number of Column is to be programmable.

    so if the source of data has 4 fields...
    i want it to behave as its a 4-columns layout

    while, if the source now has 7 fields...
    the end result would show 7 columns.

    Please refer to my test UX and picture
    to illustrate my wish

    thansking everyone in advance

      I don't know if you had found these (I've had to bookmark them because I can't seem to ever find the right search terms on the documentation site to find them again):

      Client-side Templating Syntax:
      Client-side Templates overview:

      That being said, I wonder if you might want to look into going the "setListColumnsAndPopulate" method route:

      Also, maybe look at the listbox setDisplay method:

        Thank you Jeff for the link and directions ...

        I have now able to produce DYNAMIC-COLUMN

        enclosed a working sample ..

        However, despite requesting x columns to show
        like first-4 columns , the List-Control would show an extra 3 unrelated columns at the end.

        What Have I done wrong ???

        appreciate help from the community.

          Trust this sample-dynamic column exercise would benefit many ...
          dont believe i have seen any working example or video related to such
          good feature and functionality ...

          I thanks all of you .. Please help me !

          Once I get this done ... i would like to see this feature for
          "FREEFORM" layout type ... can this be done ?

            Re: Dynamic template

            //populate the List with the first 3 columns in data
            var ops = {columnCount: 3};

            I would like to know if my sample above not been impleted with the correct parameters ??
            i confirmed that my code would produce the proper column-count to show

            however, the final LIST-TEMPLATE would include three extra columns

              Have you seen Selwyn's video titled, "Dynamically Populating a List Columns and Data - Generic SQL Table Viewer" ?
              You can find it here:

                You can find it here:
                Yes I had ... this is a client-sided , believe the video is about server-sided with xbasic.

                i am merely doing what the documents that Jeff suggested ...

                i rely strictly on this javascript function :
                //populate the List with the first 3 columns in data
                var ops = {columnCount: 3};

                i asked for 3 columns, i got three
                i asked for 7 columns, i got seven

                all working BUT ... additonal 3 columns added UN WANTED

                has anyone out there ever used such ?
                i just eventually want this to be self-supported stand-alone phonegapped android app
                no ajax call back ... just rely on static datas and local storage and munipulate everything
                using javascript

                appreciate help from experienced alpha-er

                  hmm speak too soon, perhaps the Selwyn's video indeed has something
                  let me watch that video today ... However, its the Javascript that i am asking.

                  the Sample UX enclosed should give you a real look at the issues i am facing
                  while i dont expect a fix from you, but would appreciate a suggestion or direction
                  to solve this issues ....

                  I could perhaps add something in HTML to hide the last 3 columns (unwanted 3)
                  with display:none; ?

                  best to see it works as specified by Alpha's documentation :

                  //populate the List with the first 3 columns in data
                  var ops = {columnCount: 3};

                    Re: Dynamic template

                    Instead of getting _data from the list object, a better starting place would probably to use the dialog object's getListData method.
                    It will give you the data without the "*" keys.

                    They are showing those 3 extra columns because you leave them in there when you create your listData array.

                    The below is what I would use for this particular case ...even though it wouldn't work well for more complex data pivoting requirements.
                    The below could replace all your "click" event code for the GENERATE button:

                    var sourceData = {dialog.Object}.getListData('source1');
                    var sourceDataLength = sourceData.length;
                    var destinationData = [];
                    var rowData = {};
                    var i;
                    for(i=0; i<sourceDataLength; i++){
                    	rowData[i+1] = sourceData[i].title;
                    console.log('destinationData: '+JSON.stringify(destinationData));
                    var ops = {columnCount: sourceDataLength};

                      Re: Dynamic template

                      BTW, at about 7 minutues 45 seconds into Selwyn's video he shows the JavaScript (which he creates in xbasic as a string to send back to the browser) to populate the LIST control. That is the piece of code I was trying to point you to. Notice that that Selwyn uses the same AA JavaScript method to populate the LIST as Jeff did - {dialog.object}.setListColumnsAndPopulate(…).

                      Jeff uses the "ops" parameter, Selwyn does not. I'd use Jeff's code.
