STOP Moving Selections in a Listbox

mohan2391 — Wed, 25 Nov 2020 16:16:04 GMT

Hi,

I have a filter (ListBox). After this object get selected with any value, if i press the UP_ARROW/ DOWN_ARROW the selections in the listbox are varying/moving.

I came to know that it's 1 of the qlikview features but i don't want the moving of selections.

How can I stop moving the selections in the LISTBOX by pressing ARROW keys in keyboard ?

You want to be able to select in your Listbox using a mouse button, but not by pressing Up/Down arrow keys?

Or do you want to block all selections in your listbox?

AFAIK there is no standard QlikView feature to disable selection movements using UP/DOWN ARROW keys. The User Interface has been standardised and works the same in every document in every object. That's one of the main advantages of modern user interfaces: predictability.

Any particular reason why you want to break it up in a single listbox?

Hi Peter,

I just gave an example with single list box but it is presented there in all list boxes.

So searching for a way to disable that option in all list boxes.

Why - what's the problem with this behaviour?

Hello, Mohan!

You can solve this task with "Lock" option.

Make a selection trigger of your field with action "Lock Field" and set a field which you want to lock.

After that the field will be insensitive for selections.

For unlocking this field use a button or something with action "Unlock field".

Wirting on same old post, but user reported this issue when user selected something in filter and filter is closed or hided using some variable and then user is using keyboard to do page scroll down and still selections are changing. I tried to actiavte another object when selection value change but that't not helping again.

Any idea , why activate object on selection change is still allowing keyboard up/down arrow to make selection in the filter?

The arrow-selections happens only if the object is active. So clicking on anything else will deselect it - and like already mentioned above be a quite normal and standardized behaviour.

Beside this I suggest to review the UI design because the need of scrolling within a dashboard caused a rather bad user experience.

Nevertheless you may apply a workaround (there may be other disadvantages by using it) by using an expression instead of a field as source for the list-box, for example something like:

aggr(only(Field), Field)

Thanks Marcus for your response.

I will try your suggestion but I am still curious to know that if "Action->Layout->Activate Object" can take the focus from list box to another object or not. Technically it should but it's not working that way. Like in Web development there is term called "focus", so I was expecting the "Activate Object" will take the focus. If it's bug in QlikView then I can understand and will no more behind this functionality.

Thanks,

Jas

I'm not sure if activating an object is really identically with moving the focus on it or if it are two different properties/features. Important in this regard is also the context in which it's applied - within the desktop client or the IE plugin or the AJAX client and with which major-release these things were development and are used.

Beside of this is my personal recommendation to forget all these gimmickry of creating an own usability with showing/hiding/moving objects and/or jumping between them and/or the sheets and/or applying all kinds of pre-selections with variables and/or set analysis and/or alternates states and similar things. It costs easily more time and efforts as the entire application development without any guarantee of improving the user experience - rather the opposite will happens.
