Limiting checkbox selection to 10

[powerapps890]

I want to limit the checkbox selection amount to 10. How can I do this?

Hi @powerapps890 

Every time check box is checked or unchecked - load the information to a collection.

Then check collection count using CountRows function and apply the logic to disable your checkboxes.

Hi @powerapps890 ,

just to elaborate on what @RezaDorrani advised, do the below steps:

1. set this on OnCheck property of the checkbox

Collect(collCheckBoxes,{selCheckBoxID:ThisItem.ID})​

• Set this on DisplayMode property of the CheckBox

if(CountRows(collCheckBoxes)=10,DisplayMode.Disabled,DisplayMode.Edit)​

I hope this resolved your issue if you see any challenge/need further help please let me know I am always happy to do it for my community.

Another approach you might consider...a Toggle control.

Place a toggle control on your screen (not in your Gallery) - let's call it tglMaxChecks.  Set the Default Property to:  

CountRows(Filter(YourGalleryName.AllItems, yourCheckBoxControl.Value))>9

 On your Checkbox Control in your Gallery, set the DisplayMode to the following:

If(!tglMaxChecks.Value || YourCheckBox.Value, DisplayMode.Edit, Disabled)

This will allow your users to check 10 checkboxes.  Once they check 10, the checkboxes will go "disabled", except for the ones already checked (so they can uncheck if they desire).  

Just another approach but no variables or collections needed.

EDIT: Oh, and you would also want to make the Toggle Visible property false.

This works, but every time I use my filter I can then select 10 checkboxes filtering on that whereas I want 10 checkboxes allowed in the entire app. I also already have data from previous answers populated. Including those I want the user to have to uncheck them to make additional selections. This only works for me if I don't filter. @RandyHayes @KrishnaV

Hi @powerapps890 ,

on default use:

If(ThisItem.Title in Filter('CCB Voting','Created By'.Email = varUser.Email).Title || ThisItem.ID in TempCollection.Value, true,false)

on DisplayMode use this:
 

If(
    (CountRows(TempCollection)<10 && CountRows(Filter(
                'CCB Voting',
                'Created By'.Email = varUser.Email
            )) < 10),
    DisplayMode.Edit,
    If(
        If(
            ThisItem.Title in Filter(
                'CCB Voting',
                'Created By'.Email = varUser.Email
            ).Title,
           true,
            false
        ) || If(
            ThisItem.ID in TempCollection.Value,
            true,
            false
        ),
        DisplayMode.Edit,
        DisplayMode.Disabled
    )
)

I hope this resolved your issue if you see any challenge/need further help please let me know I am always happy to do it for my community.
