ShowAsTree - Expanded

mihail_kolev

Hello,

I'm making a treeview (Repeater -> ShowAsTree) of some data. The only problem i have is that the treeview is always collapsed by default. Is there any way to show the tree Expanded by default or expand it after data is loaded by some code? Thank you for any suggestions.

Did you come up with a solution to this? I have the same requirement to manipulate the expanded/collapsed states.

Have you looked at page Chart of Accounts Overview (634). In the AL function

OnPageAll it says

IF ISSERVICETIER THEN
ExpandAll
ELSE
InitTempTable;

Does that solve your problem?

Sorry that just build the rows in depth. The view is still collapsed (underneith it is in fact fully expanded but there is a view on top of that - that is collapsed). There is only the runtime functionality that can expand all and collapse all.

hmm that's weird, i have a page with treeview too, but mine is allways expanded when i open it :-k

But for handling by code, you could try to do it with sendkeys. The expand/collapse toggle is ctrl+shift+Q

mihail_kolev

what type is the page, how you run the page...?

it's a ListPlus and i run it by code : Page.Run()

Have anyone managed to resolve this problem ?
I have a similar situation, I want to modify Page 6520 Item Tracing so when to user hits button Trace the results will be shown in Expand All. It works in Classic Client but in RTC the code for Expand All, Collapse All is not available.

SendKeys

Thank you for answering so quickly.
I thought about SendKeys but seems complicated since the shortcut Ctrl + Shift + Q is only for one line not for expand All. I didn't see any shortcut for Expand All. If I use this shortcut I would have to move from main page, after pushing Trace button, to the first line an then to all the other lines. I don't know if this is even possible, I must admit I'm quite new with pages.

I noted this small issue in our books. When it comes out to the market is a good question?

Hi!

We tried a long time, but finally we found a workaround for it!
Add this code to the OnOpenPage()-Trigger. The variable WshShell is an automation of the type "Windows Script Host Object Model.WshShell".

IF (ISCLEAR(WshShell)) THEN BEGIN
CREATE(WshShell, FALSE, TRUE);
END;
WshShell.SendKeys('+{F10}E{ENTER}');
// menu key + E + Enter
CLEAR(WshShell);

Note:
The keys to send depends on the language. This is working for ENU.

wow, nice tip :thumbsup: this could be useful not only for expanding a tree view. Thanks for sharing

EDIT: the topic is now [solved]

mgm

works fine =D>
