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.

    Drag scroll - scrolling past container and bounce-back

    It's amazing what users decide to try then complain about at length. At least to me it is, but I gotta fix it.

    I have a repeating section, set as a scrollable container. My users/customers/testers have demonstrated that they can hold their finger down on the container, drag the contents well off the top or bottom of the container, and when they let go, the contents scrolls back into view. So far, so good.

    But, for instance, if they drag the contents well above the top of the scrolling region, then let go, it bounces back but not with the very bottom rows of the content in view.

    Is there a way to manage this? IOW, if the user drag scrolls well above the container - so that the contents are out of view, then let go, the bottom row of the content should be at the bottom of the scrollable container.

    Re: Drag scroll - scrolling past container and bounce-back

    Repeating sections are not built for mobile use... it is an inappropriate design use. The best UI is one of ease and expectation. If a user can do something that results in odd or bad app behaviour, then the design needs to be improved. It's all about user experience. If you design something that doesn't misbehave, then it doesn't present itself for complaint.

      Not every situation is ideal David and we know we want to upgrade this to one of the new controls in V12 (probably the Viewbox) when time/schedule/budget/calendar all work for us.

      "You go to war with the soldiers you have" and I'm managing a project with the design, tools and constraints I have.

      If you don't have an answer, that's OK, but if anyone else has a suggestion, that would be most welcome.

        You also have to know when to cut your losses and not waste time and effort on something that is not feasible or maintainable.

        The only answer is to advise your client that the tools used are not mobile friendly and they'll have to live with a relatively minor annoyance until the correct tools are employed.

        I see this all the time. Shoehorn fixes that usually end up making things worse... and take buckets of time to implement and usually break on the next minor change.

          I added a button at the end of the list to ensure that the bounce back never fully hides the data

            So - I only have AA 4+ and I tried to relicate your issue and can't get ti repeating section to do what you are saying, so maybe it just can't happen in 12 - watch this quick video.

              List controls in certain conditions do that bounce back thing that is super annoying and I know exactly what he's talking about. Often, if you just use "fill container" that will solve it. Just move everything else into a panel header. Now that is with the list control however - I would not be a bit surprised if the same sort of fix would subsequently fix the issue your seeing in a repeating section, as I said just add an element to the bottom inside the repeating section so that the bounce back at the end will not result in the data hidden. I say a button, because it doesn't have to have a hover effect or a click event just a block that takes up space, now that being said you cold probably put any sort of spacer say 50px height and this would stop what appears to be an issue...good luck. Perhaps you could put a break height following the controls. ONce you know what the bounce back distance is you can set the break height for that amount...again good luck!

                Re: Drag scroll - scrolling past container and bounce-back

                Thanks, but I still don't see anything that makes sense to try - kinda like shooting in the dark.

                But I wonder: There are custom scroll indicator settings that include the onPull, onPullRelease and onPullEnd events. Can any of these events be used to help? Maybe stop the window contents from being pulled past their end? Or, set the bottom of the window contents at the bottom (maybe plus 10px) of the container on the release or end event?

                While Alpha's contextual help here offers a bit of information, it's like saying "p" is a pointer variable but leaving you with no idea what to do with it.

                  while it may not make sense, it does work for me. add an element the size of the scroll, now what I noticed is that different browsers/devices seem to have slightly different bounce backs but a certain size element did the trick for me. To be exact this was only as it pertained to much smaller device screen sizes, other devices such as an ipad were fine but on a small screen the bounce back was hiding the last row. Adding in the button under it made the bounce back simply not show the button as it bounced back to hide it and not the data. put the list control in a container.
                  EDIT: I don't know why I keep going back to the list control when your clearly asking about a repeating section.
                  have you tried to add in a button under the last row? Maybe put it into a container?

                    I set the padding-bottom:65px; for the container, and everyone's happy with that. Except iPhone testers. They drag the contents way past the top of the container, let go, and get bounceback that sends the bottom-most couple of rows past the bottom of the container.

                      That's why I went with the button as it stopped just that behavior for iPhone users

                        Steve,

                        I have no input on the issue... I just want to work in your office location.
