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.

  • Hiding list control columns

    I'm trying to hide columns on a list control on a UX. I've been able to hide the fields successfully, but the columns are still accounted for in the list control, so I end up with white space between some columns.

    I checked the option in the list layout to hide column if field is hidden, and have the show/hide expression for the field set to call a javascript function.

    The only thing I could think of is the layout property mentions that if a server side show/hide is used, but the fields tab in the list control doesn't mention if the show/hide is server or client side. I'm thinking server since you have to state Javascript: at the beginning of any javascript code for the show/hide.

    I've only been able to find one source explaining the show/hide expression in an AlphaSoftware video, nothing on hiding the column or what is actually hidden.

    Any insight into this is appreciated!

    Re: Hiding list control columns

    Can you explain what your use cases are, please?

    There are plenty of ways of doing this.
    This code looks to see if the column star has a value if it does not it uses different html.

    {*if star == 'star'}
    <div class="subHead_Heading">
    {Year} {WineName}

    <div class="sub_body">
    {Qty} {Size} {Location}


    <div class="sub_body">
    {Qty} {Size} {Location}


    You can also toggle templates based on some criteria.

    Here on a button, I am changing templates and a little more.

    //change Layouts

    {dialog.Object}.__listLayout = 'Default';

    case 'Default':
    {dialog.Object}.__listLayout = 'complex';
    rowHeight = 62;
    case 'complex':
    {dialog.Object}.__listLayout = 'Default';
    rowHeight = 134;
    currRow = Math.round(currPos / rowHeight) + 1;

    //go to our current row and put it at the top of the view
    var options = {};
    options.mode = 'top';

      Just set the column width to 0px in the layout properties.

        Just curious... why try and hide the columns? Are you showing/hiding based on other column data or criteria? Or you just don't want a column to display?

          Re: Hiding list control columns

          Thanks for the reply Michael, I saw a post by Davidk going into the freeform/multiple layout feature. It would most likely work, but it seems a bit time intensive for something that would appear to be apart of the list control properties via checkboxes.

          @iRadiate, I think I'll look into this option, if I can do it dynamically.

          To answer your question David, I am trying to hide columns based on information in this list controls parent. In the parent list, the user can enter up to eight characteristics, in the child list control there are eight matching checkboxes. This has been a complicated task for me because I am converting a form that is filled in by hand to data. On the form there are eight fields to put part characteristics to check for, then underneath there are checkboxes to match them; as parts come in, inspectors put down a lot number, then check off each characteristic as they inspect the items. They don't always use all eight of the characteristics spots for each part. On my child list control, I don't want to show the unused checkboxes as they are not relevant. If I find time I'll try to upload a copy of the document in question. I have been able to hide the controls, but end up with white space where they should show up.

            Above the yellow line is the parent record, below the yellow line are all the child records. The slanted column headings are what I'm working on. The headings in the slanted columns apply to all the child records.

              I have made a component to show my idea

              I am not still sure what you are trying to do.

              Are you collecting data or just displaying it?

                I'm collecting data. The user enters it.

                  Thanks for the example Michael. I'll see if I can incorporate it into my controls.
