Interactive Checkboxes within Gallery

Posted on by gonzalesbarrett

Hello all,

Couldn't find any information on this question in the forum so appreciate any feedback. I have two different checkboxes each within its own gallery. The checkboxes contain the days of the week. I was hoping to make it so that if I selected two days in the first gallery that it would grey out those two days from the second gallery. For example, if I choose Monday & Tuesday in the first checkbox then I would not be able to select those two days in the second checkbox.

Potentially unrelated information, the checkboxes are populated by a list within square brackets. I am using a hidden label to count the number of checkboxes selected. So if I select two days then the rest of the days are disabled within the checkbox.

Please let me know if you need any additional information and thank you for your time.

Sure!

Set your Items property of the Galleries to: Calendar.WeekdaysLong()

Then set your CheckBoxes Text properties to: ThisItem.Value

In the second gallery, set the DisplayMode property to:

If( !LookUp(Gallery1.AllItems, Checkbox1.Text=ThisItem.Value && Checkbox1.Value, true), DisplayMode.Edit, Disabled )

Where Checkbox1 is the checkbox in the first gallery. Change as needed.

I hope this is helpful for you.

Hey Randy thank you for the quick response.

That seems to disable the entire second checkbox. Is there a way to only disable the specific days that have been selected in the first checkbox so those days cannot be selected in the second checkbox, but other days still can? Ideally the goal is two select two days from the first checkbox, remove those two days from the second checkbox, and then still be able to select two different days in the second checkbox?

Attached a poorly edited photo below to try and get my point across :).

Thank you again for your time.

Yes, that is what I provided you should be doing.

Did you apply the DisplayMode formula I provided to the CheckBox in the second gallery? Looks like you might have put it in the first.

@RandyHayes,

Hmm not sure what I am doing wrong but the now it says "ThisItem" isn't recognized. I made sure I put your formula in the second gallery. Fairly certain I followed the rest of your instructions correctly I keep going through to verify and everything else seems right.

Thanks again

Edit: I got it had the formula in the gallery not the checkbox I misread. My apologies thank you so much

Good deal! Yes, needed on the Checkbox in the Gallery. Controls in the Gallery will all have a ThisItem available to them. Anything *at* the gallery level or above will not have a ThisItem available.
