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.

    Control Bar Button List - Hide Single Button in List

    Hi all,

    Is there a way to hide a single button dynamically in a button list inside of a control bar?

    I would like the presence of certain text in a form to enable a button in the control bar.


    Re: Control Bar Button List - Hide Single Button in List

    You mention 'hide' and 'enable', but I believe you want 'enable'. Hiding a button of a button list would look odd.

    I'm can't quite see how getting the ControlBar object will help with this. Since the ButtonList is within the ControlBar, even though I can get the ControlBar, I can't see getting at the ButtonList... at least for the purposes of disabling one of it's buttons.

    You can get the ButtonList directly doing this...

    	$('{dialog.ComponentName}.V.R1.CONTROLBAR_1.Buttonlist1.1').disabled = true;
    	$('{dialog.ComponentName}.V.R1.CONTROLBAR_1.Buttonlist1.1').disabled = false;
    Where CONTROLBAR_1 is your ControlBar name, Buttonlist1 is your ButtonList name, and the number (zero based) following Buttonlist1 is the number of a button in the ButtonList.

    You'll need to pick the appropriate event for your Text Control. As a test I put the above code into a Text Control onKeyUp event. In my case I have 3 buttons defined... and they render as Buttonlist1.0, Buttonlist1.1, and Buttonlist1.2. In this test the middle button will be disabled if I type "test" into the Text Control... but will be enabled for anything else.


      Re: Control Bar Button List - Hide Single Button in List

      I think you just need multiple control bars. Then change control bar based upon the value. This is in a way like show hide.

      On a naughty note can we get a pointer to the controlbar so we know which one is active?


        Re: Control Bar Button List - Hide Single Button in List

        Hi Michael,

        Can multiple control bars be display horizontally beside each other in a panel footer though? Tried this yesterday to avail.



          Re: Control Bar Button List - Hide Single Button in List

          You would not do it quite like that.

          You can have 2 lines in a control bar.

          So make multiple controlbars but only display one at a time.

          Have a look at this

          It changes control bars


            Re: Control Bar Button List - Hide Single Button in List

            Very nice!

            I've been following David's example and have it working;

            $('{dialog.ComponentName}.V.R1.CONTROLBAR_1.Buttonlist1.1').disabled = true;
            $('{dialog.ComponentName}.V.R1.CONTROLBAR_1.Buttonlist1.1').disabled = false;

            Do you know if I can change the icon via something similar? i.e. instead of .disabled maybe .iconName?


              Re: Control Bar Button List - Hide Single Button in List

              No I am not sure how, David is a master. I would suggest that you embrace multiple control bars as they "recycle" your data, items etc. Since devcon 2016 I have tried hard to embrace the Alpha paradigm.

              The viewbox and control bar are just fantastic.


                Re: Control Bar Button List - Hide Single Button in List

                If you wanted to hide a button in the button list, you could do like David said, but it would be like:

                $('{dialog.ComponentName}.V.R1.CONTROLBAR_1.Buttonlist1.1').style.display = 'none';

                The button list control is very flexible. However, the button list builder only scratches the surface and it omits some important properties that you can only get to by manipulating client-side.

                To change the icon, inspect the DOM differences between two buttons that you temporarily hard-code with your desired icons in the buttonList builder and then use the $ syntax client-side to change the icon on the appropriate event.
