I have a simple app created which is attached. If I click on '1' in StartDate it brings up all the months in Start which I would expect. If I then choose, say March within this list box (which contains the expression) it highlights it green, which I would once again expect. However, when I click on March again to deselect it, it clears all the selections which I would not expect. Is this typical Qlikview logic?
I feel that if 'StartDate' is linked to 'month' in your model, then it should not clear all selections on deselecting a value from month listbox. However, if StartDate is not linked to month and you have written some macro then this issue might happen.
I believe that is how it should work. Clicking on an item makes that the selection. If you have multiple items selected, clicking on one will make only that one the selection.
If you want to deselect an item, use Ctrl + Click.
But if you click on the same one that has already been selected it should deselect it while keeping the others that have been clicked 'selected', should it not?
It doesn't seem to be working that way in QlikView. QlikView seems to treat that as select only that one. Any time you click on an item, it makes that the selection whether you have other items selected or not.
The Ctrl + Click will allow you to deselect and add-select items when there are selections already made without affecting those selections.
I can't seem to remember how regular Windows list boxes work. I know the Ctrl + Click is utilized, but I'm not sure if clicking an item will make that the sole selection as we are seeing QlikView doing.
I fired up good, old MS Access to test out the List Box functionality. There are two multi-select modes in the List Box, Simple and Extended. Simple works kind of like you describe, where clicking on a selected item will deselect it. The other part of that is no Ctrl + Click is utlized. If you click on an unselected field, it will add it to the selection. Extended works like QlikView. If you click on an item it will make that the selection. You must utilize Ctrl + Click to select multiple or deselect single items.
I think both ways are valid. I prefer the QlikView/Extended method, since that's what I'm used to. In past development, I have used the Simple method when the end users preferred it.
