I have been trying to make some TABS invisible.  Here is the code but it is not working for me.  TabPages are always Visible. How can I make them invisible?


// Hide/Show Elements
IF Blue <> YES Then {VISIBILITY(TabPage0,0) }
IF Blue = YES Then {VISIBILITY(TabPage0,1)      }
IF Red <> YES Then
{VISIBILITY(TabPage1,0) ; VISIBILITY(TabPage2,0) }
IF Red = YES Then
{VISIBILITY(TabPage1,1); VISIBILITY(TabPage2,1)      }

Red and Blue are combo boxes..  When Blue is selected I want to show Tab0
When Red us selected U wabt ti show Tabs 1 and 2.  Sometimes Both Red and Blue can be selected, and sometimes none are selected.  Not show is Tabs 3 and 4 that are always visible.

Code is in On Form Entry section.  When programe code is good was going to make it run when the combo boxes changed also.

Thank youjfor the fast reply.  I went to that link and it sounds like Bob Hansen was asking someone else to try his solution.  I did not see another answer to him.  As I read all the postings there I did not see anyone who has done this.  Will this be in the next version?  Is there a simple way to make all fields invisible on the Tabs even if the Tab label shows on the bottom??

Thank you for solution but it does not work for me.  When I do that I end up with moving wider across the screen.   So  I tried to make the tab pages narrower so they could still be side by side but I have too many fields on some of the tabs so I can't do this.  I really wanted to see the pages on  top of each other.  So I guess there is no way to this.

Hello,

You could also do this without using a regular tab group at all. You would add a command button for each "Tab Page" you want to have. When a button is clicked on it will show only the elements that are on that "Tab" and hide all the elements on all the other "Tabs". So you create your own tab group by using programming. If you do not want a "Tab Page" to be visible you hide the command button and move the other command buttons to compensate for the one that is invisible. Depending on the size of your tabs it would take some programming but you could do it. And if you do, you would also be able to have On Tab Page Show and On Tab Page Hide events, since you control the hiding and showing of "Tab Pages".

Hello Bob,

I think you meant Form and not Canvas. The Canvas is where you put elements if you do not want them to show up in runtime, Ghosted elements are on the canvas.

Hello obfusc88
I just had a few more thoughts of help for you if you try to make all elements invisible on a TabPage.

1.  Remember to also make static text, boxes, and lines Invisible, not necessary, but makes a much cleaner picture, especially when combined with my next thought.

2.  Change the label on the TabPage to make it empty.  This will shrink the width of the Tab on the bottom to a very small area, (almost invisible).  Now if someone clicks on that Tab by mistake, they will see a totally blank page because you did step 1, removed ALL elements, not just data elements.

Here is the code to change the label:

IF TurnOffTabPage = TRUE Then {
     LABEL(tabPage0,"")
     VISIBILITY(Element1,0)
     VISIBILITY(Element2,0)
     VISIBILITY(Element3,0)
     >
     >
     >
     VISIBILITY(Element99,0)
     }

IF TurnOffTabPage = FALSE Then {
     LABEL(tabPage0," Original Tab Label ")
     VISIBILITY(Element1,1)
     VISIBILITY(Element2,1)
     VISIBILITY(Element3,1)
     >
     >
     >
     VISIBILITY(Element99,1)
     } 

IF you don't think there would be a confilct with various labels on the Tabs, you could capture the current Label value and save it as a global variable, then use that global variable later when you need to restore the name of the label.  That wpuld make this more generic, and the value of the label would not be hardcoded.  But that is probably not useful if you are manually entering the element names to be toggled anyway.


Hmm, that raises a new question....It should be possible to use a loop to make many elements VISIBLE, or READONLY, etc. but how can we identify the parent element of the data elements?  For instance, I don't think we can know that a particular element is on a TabGroup on ANY TabPage, nevermind knowing which specific TabPage it might be on.  Any chance that the magical Version 2 will provide this capability  ..the ability to ID the parent that all elements are attached to?  We now can see parenting when we move elements, so the logic is there under the covers somewhere.  This is the type of thing that Mark usually whips out right away.  Go for it Mark

When I've done this I've put a static text element on the middle of the form, saying "This tab page is intentionally blank". I've formatted it nicely, with a coloured border. When you make the other elements invisible make this message visible, and vice versa.
