show/hide tabs in linked Content

[Steve Wood]

Has anyone expiremented with trying to show/hide tabs in a grid's linked content area (see image)?

The definition of the linked Content area is held in tmpl.linkedContentDefinition, so I think it is possible to modify the contents of that parameter through events.

The idea was to hide a tab if there were no records in that particular related grid.

Re: show/hide tabs in linked Content

I found a potential solution. I can create different Linked Content Sections, one for each that I want to show/hide, then use this syntax in the appropriate freeform area (Alpha automatically places the linkedcontentsection code in freeform).

<%a5
if CONDITION = .t.
%>
{LinkedContentSection:GRID_A}
<%a5
else
%>
{LinkedContentSection:GRID_B}
<%a5
end if
%>

Did this work for you Steve?

Re: show/hide tabs in linked Content

My solution works fine as a server-based solution. The browser has to refresh to cause any content section to show/hide. I am working through a suggestion by Selwyn to make it a client-side event using watch events.

Re: show/hide tabs in linked Content

Now I need this too. I'm OK with server-side but wouldn't mind client-side action.

I even tried this in the OnGridExecute Event:

dim tabstr as c
tabstr = <<%a%
<[6]<gridName="LOCATION_DAILY_ORDER_LIMITS_NEW">
<linkFields="LOCATION_ID (C) = LOCATION_ID (C)">
<hideLinkFields=.F.>
<inheritParentStyle=.T.>
<tabLabel="Daily Order<br> Limits">
<overridesettings="">
<workingMessage="">
>%a%

e.tmpl.linkedContentDefinition = stritran(e.tmpl.linkedContentDefinition, tabstr)
flagMustRecalculateAllProperties = .t.

And even though debugger confirms that the string was successfully removed, the linked grid continues to display.

Steve - did you get this working for Client side?

Re: show/hide tabs in linked Content

No, I haven't found a solution yet. For now I've had to tell the customer that it can't be done.

Re: show/hide tabs in linked Content

I'm waiting for a feature in A5Web to do this from the very early start of my using (only 8 moth ago :-). I really hope Selwyn will implement it in version 11 (and release it in a feature pack before its release).

For now, what is your opionion the following work around:

create a bunch of action buttons, uses images shaped as tabs for them, and show the desired content in the grid. The action buttons provide all the necessary features to conditionally show it (even usergroup based access can be achieved in this way). Of course not as nice as the real thing but better than selling 'no' to a customer perhaps?

Re: show/hide tabs in linked Content

I did have some good information from Selwyn on this many months ago. I cant find it, which is odd because I guard those emails like they are gold. But anyway it was using watch events to 'watch' for changes in some criteria, then using ajax callback to alter CSS, probably pushing "DISPLAY:none" to hide the tab.

I have a mega-grid that is becoming more mega. It already has 12 tabs and total of 18 grids linked. Going to 18 tabs and 26 grids - but I need to show/hide the tabs depending on data elements in the table that supports the parent grid. Like if "CompanyID=1" show the 12 tabs associated with Company 1, if "CompanyID=2", show those 6 tabs, etc.

I can figure it out if the page is being refreshed (I'd just call a whole new parent grid with different tab arrangement) but not if using AJAX features like performing a search, and then selecting one of the records returned in the search. That all happens in the client using Alpha's AJAX grids.

Another thing to watch for here is you cannot control these tabs with security setting, they will always appear then once clicked tell the user in a kind-of-popup, they can't look at the data due to security settings, I've stopped using them (in this case) and put them behind image and button on-click Java Events where you can manage to use security and data filtering. The new Button pack also works well in this situation.

Re: show/hide tabs in linked Content

At the risk of showing my ignorance (and when has that ever stopped me anyway) couldn't you put each linked grid in a separate div and then use the Javascript System Event (like onRowSelect) to show or hide the div?

Setting up a condition and then using:

document.getElementById('gridName').style.display = 'none';

should work, shouldn't it?

Of course, that's the theory.
Now in practice, I want to hide a grid if there are no records in the grid. How do I use javascript to determine the number of records in a "child" grid?

Thanks.

Re: show/hide tabs in linked Content

Not sure how you set up your tabs, but if it's A5 doing it, then Jay is right, but you may not need your own div id 'cause A5 supplies it. In another recent thread here about Tab Focus, there's some code as follows:

$('GRD_SPLIT__MASTERTEMPLATE.0.PANE').style.display=none";
$('GRD_SPLIT__MASTERTEMPLATE.1.PANE').style.display="block";
$('GRD_SPLIT__MASTERTEMPLATE.0.TAB').className="GlassBlueFormTABLE GlassBlueColumnTD A5TabTopOff";
$('GRD_SPLIT__MASTERTEMPLATE.1.TAB').className="GlassBlueFormTABLE GlassBlueDataTD A5TabTopOn";

which displays and hides tabs. There is a focus problem which I'm looking at, however.
