Getting the value of a checkbox inside nested gallery

Hi all,

Is it possible to get the number of checkboxes ticked inside a nested gallery?

I have a gallery with headers as items, then a nested gallery that shows under each header. I will attach a screenshot below.

I would like to make it so that when you select a few items with the checkboxes, a button to delete them will be labeled something like 'Delete 5 items'.

I have tried a few different formulas but can't seem to get one that works.

The formula below just returns blank as the result for the condition, but the source does have data.

CountIf(galProcessHeaders.Selected.galProcesses.AllItems, chkProcessSelection.Value)

Thanks

Hi @BradonK ,

Add a Button control into the Parent Gallery. In the Text property of that Button, use an expression like below:

"Delete "&CountRows(Filter('Your Child Gallery'.AllItems, Checkbox1.Value)) & " items"

Unfortunately that still returns 0 and says that the check box is blank.

@BradonK - I assume you have actually tried checking one of the checkboxes?

Could you please share a screen shot, which ideally displays:

What you have in the expression for the Text property of that Button
The controls for the Parent and Child Gallery in the Tree view

Thanks @BradonK . For a reason I still cannot comprehend, you cannot access the output of controls inside a container.

You would need take both the Button control and the Checkbox control out of those containers in order to achieve what you're trying to do.
