Hide a check box on other lines of gallery, if one is checked?

Posted on by jed76

I have a gallery with lines showing two checkboxes on each line. When one of the checkboxes is checked, I would like to hide it from all other lines. Any ideas please? I have tried counting the rows and if the number of rows with a checkbox checked is > 1, hide the checkbox, but this obviously hides the checked box as well!

Many thanks.

Hi @jed76,

OnCheck of the checkbox you can set a variable such as:

Set(varSelectedID, ThisItem.ID)

OnUncheck of the checkbox do this:

Set(varSelectedID, Blank())

And set the visibility of the checkbox to:

IsBlank(varSelectedID) Or varSelectedID = ThisItem.ID

This works a treat but when I visit the page again with a different set of items (the gallery is filtering based on a job number), the status of the checkboxes remains. Is there a way to "reset" each time? Perhaps by using ThisItem.<checkboxvalue> instead of .ID? Many thanks

What I really want is this:

Each line of the gallery (which is filtered based on the job number being viewed), has TWO check boxes. When one is checked, the other box on the same line is hidden and the same check box on all subsequent lines are also hidden. The same applies the other way round.

So:

LINE 1: CHECK BOX A TICKED, CHECK BOX B HIDDEN
LINE 2: CHECK BOX A HIDDEN, CHECK BOX B VISIBLE

and vice verse......

But, I also need it to "reset" when viewing a different job number in the gallery....

Many thanks.

Hi @jed76,

Checkbox 1:

OnCheck: Set(varSelectedID1, ThisItem.ID);

OnUncheck: Set(varSelectedID1, Blank());

Visible: (IsBlank(varSelectedID1) Or varSelectedID1 = ThisItem.ID) And varSelectedID2 <> ThisItem.ID

Reset: varReset

Checkbox 2:

OnCheck: Set(varSelectedID2, ThisItem.ID)

OnUncheck: Set(varSelectedID2, Blank());

Visible: (IsBlank(varSelectedID2) Or varSelectedID2 = ThisItem.ID) And varSelectedID1 <> ThisItem.ID

Reset: varReset

The control to reset (in my case it's a button but you can also add this to the OnChange property of a drop-down - assuming that's how you apply your filter):

Set(varSelectedID1, Blank()); Set(varSelectedID2, Blank()); Set(varReset, true); Set(varReset, false);

@Akser Thank you so much for this solution. I have just realised though that this doesn't appear to be working until someone selects one of the checkboxes again upon the gallery opening. By default, all boxes are still visible? Is there a way to set this default behaviour as soon as the gallery is opened? For example, when I open the gallery, one of the tickboxes is ticked (for example on line 1) but the same tickbox on line 2 is still visible until someone checks a box again? The default for each box is set to "ThisItem.IsTicked", so that is working, but the visible property isn't. Many thanks.
