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.

    {dialog.Object}.populateDropdownBox error

    Am i missing something stupidly simple...in a dialog with only a new blank dropdown and button.

    In the button OnClick event is:

    Code:
    {dialog.Object}.populateDropdownBox('selectaddress',[['alpha 2','A2'],['beta 2','B2'],['display for c','C2']],true);
    When I click the button I get an error: Unable to get property 'false' of undefined or null referenece

    selectaddress is the name of the dropdown.

    Please help :)

    Re: {dialog.Object}.populateDropdownBox error

    I don't fully expect this to be your problem, but from the documentation (http://wiki.alphasoftware.com/~alpha...wnBox%20Method):

    controlName - name of the control (must be uppercase)
    If making the control name upper case doesn't work, can you run it in FireFox with FireBug running and inspect the error? That will give you the most information.

    Also, is this all the code in your OnClick event?

      {dialog.Object}.populateDropdownBox('SELECTADDRESS',[['ALPHA 2','A2'],['BETA 2','B2'],['DISPLAY FOR C','C2']],true);
      seems to work if all capitals.
      but still the stored value does not come yet.
      edit: works with non caps too, but no stored value if different.

        So then capitalization doesn't matter. I kinda figured that wouldn't be helpful. Most of alpha's JS functions call ToUpper() on the parameters. Something else is going wrong.....

        What's the type of the control?

          dropdown, character to return.
          I haven't figured out the return value if different.

            OK. I tried this. I tried your code exactly and got an error. I changed 'selectaddress' to 'SELECTADDRESS' and the error went away and populateDropdownBox works just fine.

            The reason you need to specify your control name in all caps is that somewhere in the populateDropdownBox code, this is called:

            Code:
            _getControlLow: function(columnName) {
                var ele = $(this.dialogId + '.V.R1.' + columnName);
                if(!ele) {
                    var rsName = this._findRepeatingSection(columnName);
                    var instNum = this.repeatingSections[rsName].activeRow;
                    ele = $(this.dialogId + '.V.R1.' + columnName + '_A5INSTANCE' + instNum);
                }
                return ele;
            }
            columnName is not auto-capitalized for you, so when $ goes to look for the control, it searches for "DLG1.V.R1.selectaddress", which doesn't exist. The dropdown is named "DLG1.V.R1.SELECTADDRESS". So, it tries to find a repeating section object instead, but there are no repeating sections. So, error.

              yes, that is correct.
              the function does say the field name MUST be in caps. the rest is ok, even the returned value comes out right.

                Sarah and Gandhi, thankyou so much! Serves myself right for skimming over the documentation; maybe I'll learn one day. I pretty much spent a whole day trying to get this to work - I was pulling my hair out - but today all is good :) God bless

                  I don't know what you were referring to here, so I assumed it was the control name (SELECTADDRESS). I didn't realize you were talking about the array of values. The value array doesn't matter, as long as it takes one of 2 forms:
                  Code:
                  // Form 1 - no stored val:
                  var arr = ['Alpha','Beta','Gamma','Delta'];
                  
                  // Form 2 - stored val:
                  var arr = [['Alpha','a'],['Beta','b'],['Gamma','c'],['Delta','d']];

                  Not sure what you were looking for with stored value. {dialog.object}.getValue('SELECTADDRESS') should return the second val - A2, B2, C2.

                    the function works as it is supposed as long as the field name is in capital, see my post #7 ( and i agreed on that with you)

                      I saw that. ;) I was more wondering what you meant by this:

                      edit: works with non caps too, but no stored value if different.

                        For the rest of the statement, originally I posted that way. Like shouting at alpha's ear to hear me.
                        And return value works too when I went back to the table to check.

                        See post 3
