how to limit to selection of check boxes max to 3?

[rajkumar88]

Hello Everyone,

Do any one know how can below scenario be achieved. 

I have a  screen with 19 checkboxes. Based up on the selection it will update the column in SharePoint list. This part is working as I Expected. 

But the issue is that users can select all the checkboxes and I am not able to limit it to any 3 or max 3 only. 

Any help on this one please?

That's why I suggested disabling the submit button instead.  That leaves the checkboxes open to be checked or unchecked, but the user can't submit until they have 3 or less checked.

For display mode you mentioned is not taking any affect at all. I am still able to select all the 4 or 5 checkboxes and can able to submit that.

If I understand currectly, implement all of your code as per previous post and also make "submit" button visible=false or visible property=if(checkboxes>3,true,false)  ?

[Pstork1]

You don't need to do anything with Visible.  The DisplayMode property I specified in my code takes care of it.

And this in the Display Mode property for the button

If(checkedBoxes > 3,DisplayMode.Disabled,DisplayMode.Edit)

The button is disabled (greyed out)  if you choose more than 3 checkboxes.

thanks for the clarification. not sure if there is anything with the code that I applied. seems to be not working. I can still see the "save" button even after selecting more than 3 checkboxes. Save is not greyed out/disbaled.

@rajkumar88  Can you provide the code from your Checkboxes? The difference between the method @Pstork1 and I suggested would depend on your users. If I took his approach which I prefer, I would get emails about the form not working correctly. But either method should accomplish your goal.

Here you go. 

1. on App start : Set(Checkboxes,0)

2. for each checkboxes oncheck property: Set(Checkboxes,Checkboxes+1)

3.for each checkboxes UNcheck property: Set(Checkboxes,Checkboxes-1)

4.  on a text label → visible property →If(Checkboxes > 3,true,false)

5. on "Save" button →DisplayMode →If(Checkboxes> 3,DisplayMode.Disabled,DisplayMode.Edit)

FYI → I have "4 checkboxes" created for this scenario.

Remove the DisplayMode. as I have shown above, and it should disable the button.
