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.

  • get the row number in a list control on button press

    Hi,

    I have a list control with a button. I need to get the row number of the list control when the button is pressed. Since this is a UX there is not rowNumber and the number I need is the one for the list for the button that is pressed. So I think i need something like the following:

    var rn = {dialog.Object}.getValue('list::Entered::<ZeroBasedRowNumber>');

    I've also tried

    var rn = {dialog.Object}.getValue(rowNumber);

    and about every variation I can think of.

    What I get as a result is just a blank so I don't think it has focus on the list control...

    any help would be appreciated.

    thanks,
    tom

    Re: get the row number in a list control on button press

    What I discovered is that when you place a button on the list control and press the button it does not give focus to that list item. If I click on the list item first then press the button on that item the row number is read and my control functions. So a button on a list control will not set focus on that list item.

      Tom,

      Did you ever figure out how to force the list to give focus to the row you clicked a button on? I have a button on my list that I trigger action javascript to open a UX control to edit that row....but if I don't click on the row first before clicking on the button, it doesn't pick up the correct primarykey to properly load the UX component. Any hints would be appreciated! Thanks....dion

        I'm having the same situation... any of you managed to get the row number without first clicking the row?

          here is a video that explains how to do it.

          http://screencast.com/t/ZQcg9hOdJ5e



          as the video shows, the row number of the row you clicked on is available in the rowNumber variable that is passed into your event handler.

          to set focus to the row of the button that was clicked, you would put this code in the button's onClick event:


          Code:
          var l = {dialog.object}.getControl('{dialog.listId}');
          l.setValue(rowNumber,false);
          alert('you clicked on ' + rowNumber + ' and we have now given focus to this row');

            Excellent! Thank you so much Selwyn. Makes perfect sense and easy to implement on my system. Appreciate the follow up.

                Selwyn,

                Doesn't {dialog.object}.getControl() return a list object? I don't see setValue in the list of methods.

                  Hi Selwyn,

                  I have been using arguments[0]. Is there any reason not to do this?

                  var rn = arguments[0] ;

                  var pkey = {dialog.Object}.listGetValue('List1','pkey',rn);

                  Thanks,
                  tom

                      Re: get the row number in a list control on button press

                      I know this is an old post, but I ran into this problem today. Unfortunately, while the solution seems straightforward, I can't quite get it to work. As illustrated in Selwyn's example, I have a button in my list with the code referenced above (in Selwyn's post), with the exception of the alert message. Once this javascript fires and the row has been selected, I want to fire some xbasic referencing the values in the selected row. I have set up the actions synchronously, wehereby the xbasic is the step after Selwyn's code. I've tested the xbasic and it works fine on its own, so I know its not that.

                      Thanks in advance for any assistance.

                        please submit a test case that shows the problem.

                          Thanks Selywn. Appreciate your response. I think I just got it working. Will report back with a test case if I run into an issue.

                            False alarm... I've attached a test case to illustrate the problem. In this example (hopefully not too overly simplistic), the list button attempts to run JavaScript synchronously: step 1: Select the row. Step 2: Run xbasic to populate the value of a textbox control. Note: In my application, step 2 has Xbasic to run an insert statement. Fortunately, the same problem exists in this simple example; that is, clicking the button does nothing.
                            What I've tired:

                            - just running Xbasic via the on click event and using an e.javascript statement to run the javascript there. Same result as above - clicking the button does nothing.
                            - In-line javascript (instead of synchronous) - runs, but most of the time performs the Xbasic first, defeating the purpose.

                            Thanks in advance!

                              i am surprised that you say 'clicking the button does nothing' -- in fact it shows a javascript error. the only way it would have 'done nothing' would have been if you were testing it in working preview using chrome and you had not opened the chrome debugger.

                              if you tested it in working preview using Internet Explorer (and you had configured IE to show javascript errors -- which is highly recommended), then you would have seen a Javascript error.

                              the javascript error is telling you that rowNumber is not defined.

                              the code you have in the button's on click event is:


                              Code:
                              {dialog.object}.runAction('js');
                              if you changed this code to:

                              Code:
                              alert(rowNumber);
                              {dialog.object}.runAction('js');
                              you would see that the alert shows the rowNumber, then you get the error saying that rowNumber is not defined.

                              this is correct -- rowNumber cannot be seen inside the Javascript action. so the error is correct.

                              your javascript action is very simple -- you don't really need a javascript action to do what you want -- therefore you should put the code directly in the button's onClick event -- and then the rowNumber variable will be visible.


                              so the code in your button's onclick event should be:


                              Code:
                              var l = {dialog.object}.getControl('{dialog.listId}');
                              l.setValue(rowNumber);
                              alert('you clicked on ' + rowNumber + ' and we have now given focus to this row');
                              {dialog.object}.ajaxCallback('','','setvalue','','',{deviceOfflineFunction: function() {   }});
