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.

  • Javascript to populate Dropdown in Repeating section

    This should be simple, but I don't see what's wrong.

    If I put this on a button to populate a dropdown outside a repeating section, it works just fine:

    Code:
               var data = '';
                data = ['one','two','three'];
                var curData = '';
                var clearExisting = true;
                {dialog.object}.populateDropdownBox('R_Dropdown',data,clearExisting);
    But I can't figure out how to get it to populate within a repeating section. I've tried, for instance, 'V.R1.R_DROPDOWN_A5INSTANCE6' and everything else I can think of (yes, I'm sure it's the 6th row) but no joy. Wassup here?

    Re: Javascript to populate Dropdown in Repeating section

    I found this if it helps...

    Code:
    {dialog.object}.populateDropdownBoxRepeatingSection(controlName,data,clearExistingData)
    The example says it's the same as the method you posted but for repeating sections. It also says it will do all rows, which may not be what you want.

      Yup, that does it. I know I'd seen that before but didn't remember it, and amazingly in several hours' effort didn't come across it. C'mon documentation!

          Re: Javascript to populate Dropdown in Repeating section

          OK, so the next step is to have a variable list of choices, with a display value and a stored value, and populate the dropdown. Got a magic function for that one? I can see a huge time sink here if I don't ask. I can provide the choices list in any format - can't really find any reference on it.

          Code:
          			var choices = '{Guard1,1},{Guard2,2},{Guard3,3}';
          			var jsData = [];
          
          			// split string into an array:
          			var parts = choices.split(',');
          			var arrayLength = parts.length;			
          			for (var i = 0; i < arrayLength; i++) {
          			    var txt = {html: parts[i], value: parts[2]};
          				jsData.push(txt);
          			}	
          				var curData = '';
          				var clearExisting = true;
          				{dialog.object}.populateDropdownBoxRepeatingSection('R_Dropdown',jsData,clearExisting);
          			}
          This just produces a list like:

          [Object Object]
          [Object Object]
          . . .

            Maybe just a format issue with the curly brackets instead of the square?
            From the Insert Method box:
            Code:
            //Populate the choices in the Dropdown Box for the 'COMPANY' field. Replace the existing choices. Each new choice that is
            added has both a display and stored value.
            {dialog.Object}.populateDropdownBox('COMPANY',[['alpha 2','A2'],['beta 2','B2'],['display for c','C2']],true);
            I'd give it an actual try but I've got to get to the bank. Hopefully it's that simple or someone else can give you a hand.

              I dunno, I've tried everything I can think of, every combination of quotes, escaped quotes, nuthin. Here are two experiments that didn't work.

              var choices = "['Guard1','1'],['Guard2','2'],['Guard3','3']";
              var choices = ['Guard1','1'],['Guard2','2'],['Guard3','3'];

                Re: Javascript to populate Dropdown in Repeating section

                this is how it should look, i think
                var choices = [ ['Guard1', '1'],['Guard2', '2'],['Guard3', '3'] ];
                var clearExisting = true;
                {dialog.object}.populateDropdownBoxRepeatingSection('R_Dropdown',choices, clearExisting);

                ps:
                i just checked against a dummy repeating section it works as expected. updates with the stored data as shown.

                  Re: Javascript to populate Dropdown in Repeating section

                  if you need to push data into an array then

                  Code:
                  //var choices = [['Home','1'],['Office','2'],['Vacation Home','3']];
                  var choices = [];
                  choices.push(['Home','1']);
                  choices.push(['Office', '2']);
                  choices.push(['Vacation Home', '3']);
                  var clearExisting = true;
                  //{dialog.Object}.populateDropdownBoxRepeatingSection('ADDRESS_TYPE',[['Home','1'],['Office','2'],['Vacation Home', '3']],true);
                  {dialog.Object}.populateDropdownBoxRepeatingSection('ADDRESS_TYPE',choices,clearExisting);
                  the commented out areas are for me when it was working and then when I changed to new one, does not affect the outcome as you know.

                    That looks promising Gandhi, thanks. It populates correctly, it'll be tomorrow probably until I can assure that it's returning the stored value, though I bet it is. Overflowing in box here.

                      Re: Javascript to populate Dropdown in Repeating section

                      I think I'm one step away from finishing this.

                      The choice list *really* comes from either a list control or alternately localstorage. So, I need to get that string and plug it in, but this is elusive. As always, I can control what the input string looks like. It seems to me that I should be able to do this:

                      Code:
                      			var cdata = obj.Resp_Choices;
                      			// cdata looks like this: ['Guard1', '1'],['Guard2', '2'],['Guard3', '3']
                      			var choices = [];
                      			choices.push(cdata); 
                      			
                      			var curData = '';
                      			var clearExisting = true;
                      			{dialog.object}.populateDropdownBoxRepeatingSection('R_Dropdown',choices,clearExisting);
                      That doesn't work. If I try to treat the whole thing as a string, e.g.

                      Code:
                      choices = '[' + cdata + ']'
                      then that fails as well.

                      What I have in more general terms is variable data to populate the dropdown list. Should not take 24 hours to figure this out.

                        Re: Javascript to populate Dropdown in Repeating section

                        Code:
                        var type = 'Home, Office, Vacation Home';
                        var type_array = type.split(',');
                        var choices = [];
                        for (var i = 0; i < type_array.length; i++) {
                        choices.push([type_array[i], i+1]);
                        }
                        
                        
                        //var choices = [['Home','1'],['Office','2'],['Vacation Home','3']];
                        //var choices = [];
                        //choices.push(['Home','1']);
                        //choices.push(['Office', '2']);
                        //choices.push(['Vacation Home', '3']);
                        var clearExisting = true;
                        //{dialog.Object}.populateDropdownBoxRepeatingSection('ADDRESS_TYPE',[['Home','1'],['Office','2'],['Vacation Home', '3']],true);
                        {dialog.Object}.populateDropdownBoxRepeatingSection('ADDRESS_TYPE',choices,clearExisting);
                        this is done with a string and results are good.
                        if you post what you have in local storage I can test that version for you.
                        (normally I save mine in local storage as json data.)

                        ps: again the commented out data is for me.

                          I don't have anything for this stored in localstorage yet. I'm trying to figure out *what* to store and in what format to work with the javascript here. Right now I'm using this string from a List control, but I can change it to fit whatever is going to work:

                          ['Guard1','1'],['Guard2','2'],['Guard3','3']

                          I tried what you suggested here, but so far no good.

                            that will show what you have to start with before converting to something else.
