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.

    Drop Down List population

    How do I create a situation where the user can add to the dropdownbox choices "on the fly"?
    I have set up a dropdownbox that is populated by a table but I can't figure out how allow additions to the choices by the user.
    Ideally there would be a "ADD NEW" choice next to the dropdownbox which would open up the table of choices. The user could add a new record, submit, and that table would close, with the dropdownbox now containing his new choice.
    Thanks!

        Hi Steve,

        Welcome to Alpha, I should have said that before.

        You are in the Application Server section here and I assumed that you were asking about lookups in the desktop version.

        If you were, then my answer to look in AlphaSports still stands. If not then I'm sorry I may have given you the wrong answer.

        In any event as you have only made a couple of posts on this forum, it is fair to assume that you are new to Alpha therefore it wont do you any harm.

          Thank you for the Welcome Keith!

          I am in my first couple weeks of Alpha Five. Previously I have been using PHPRunner.

          I'm sorry but I'm a little confused regarding your response.
          I am doing a web based applications and not desktop. Do you think AphaSports would be helpful for what I am trying to do?


          Thank you,

          Steve

            Re: Drop Down List population

            may or may not need some extra effort, but we did like this,
            give a link next to the 'drop down' to which you are trying to add values on the fly, and open up a new a5w page with an updatable grid for this database field where by user can add, edit the choices, once done, in the submit button of the grid, redirect the user back to the previous page.. by this time, the dropdown will be having the latest record that we submitted just now..

            ** all this is very simple, but pls do keep in mind that if the end-user already entered some values in text fields etc., and then wants to add a new value for the drop down, and clicked our link.. then somehow somewhere we should keep the values in those text fields in order to fill it back when the user returns to the page after adding few choices in the gird of the other a5w page.. if we don't do it, whatever user keyed in before moving out from the first screen or GONE.. **

              Re: Drop Down List population

              Take a look at the AJAX cascading dropdown code (both the .a5w and the AJAX.a5w pages) from the Web App demo files that ship with Alpha5 - it uses code like below to initially populate a dropdown box:

              Code:
              dim dbf_folder as c 
dbf_folder = _A5_Aliases.get("PathAlias.ADB_Path")
DIM tablename as c 
tablename = a5_removetrailingbackslash(dbf_folder) + chr(92) + "customer.dbf"
dim stateList as c 
stateList = table.external_record_content_get(tablename,"alltrim(bill_state_region)","bill_state_region","unique_key_value()")

stateList = alltrim(stateList) ''remove any blanks from the list
stateList = "Select state" + crlf() + stateList
stateList = [COLOR="DarkRed"][B]a5_html_list_populate(stateList,"Select state")[/B][/COLOR]
              This generates <option> entries for a HTML dropdown control.

              You could have a freeform control (if this is a dialog) that contains a text input and a button - in the onClick event for the button, you could call a javascript function that makes the AJAX call to generate the new list of <option> entries, and write them back to your <select> control using ?"$('SelectControlName').innerHTML='"+newOptionList+"';" where newOptionList is what you generated using code similar to the one in the code tags above.
