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.

    Show/Hide Expression

    Hope someone can help me solve this:

    I want to show field B (in a grid-Detail View) only if
    "Item1" is the value in field A

    So a simple Show/Hide expression for field B is:
    Field A = "Item1" and this works well as it evaluates to true and the field I want to show - shows

    BUT if

    Field A's value is populated from a edit-combo box (of 34 choices) now I am in trouble
    because the value in field A could be "item1, Item2, etc"


    Seems like I cant do anything except the actual literal value and with 34 choices and combinations to filter out I imagine that would be one long line of code, lol

    Can anyone help me or point me in the direction I need to look? I have tried searching the forum for Show/Hide and java-script forums for comparison ideas but really to no answer...this seems like it should be fairly easy for someone with experience in alpha 5 and javascript

      Re: Show/Hide Expression

      Yes that is correct as I noted in my post.
      The problem is that when you have multiple items in FieldA

      Then FieldA's value becomes concactinated with the additional selections and the expression
      FieldA = "ITem1," fails
      even though FieldA's value contains "Item1"
      its value is (on multiple selections) becomes "Item1, Item2,Item3,etc."

        Re: Show/Hide Expression

        would you try
        at("Item1", field_a) > 1

        or
        at("string_to_search_for", field_name) > 1

        here is a little screencast
