mutual exclusion checkboxes

Daniel4 — Mon, 21 Aug 2023 12:51:09 GMT

I want to implement two check boxes there are mutual exclusion. If box one are checked to true, box two must automatic turn to false. I have the two checkboxes in a dockpan.

This is what I have so far.

xaml:

c#:

How to implement the logic?

Hi,

There is no logic implemented in your code between IsCheckedOne and IsCheckedTwo properties.

private bool _isCheckedBoxOne; private bool _isCheckedBoxTwo; public bool IsCheckedBoxOne { get { return _isCheckedBoxOne; } set { SetProperty(ref _isCheckedBoxOne, value); _isCheckedBoxTwo = !_isCheckedBoxOne; // Generate notification message here to update _isCheckBoxTwo, it could differ from that sample OnPropertyChanged("IsCheckedBoxTwo"); } } public bool IsCheckedBoxTwo { get { return _isCheckedBoxTwo; } set { SetProperty(ref _isCheckedBoxTwo, value); _isCheckedBoxOne = !_isCheckedBoxTwo; // Generate notification message here to update _isCheckBoxOne, it could differ from that sample OnPropertyChanged("IsCheckedBoxOne"); } }

It is enough one property for both controls, but you need to use boolean inverting converter in second property binding.

Question like yours is not a scope of ArcGIS Pro. It is WPF part.

If you implement your checkbox logic in the viewmodel as @GKmieliauskas suggests you have to prevent recursion when you set the counter property. Here is my suggestion (i attached a sample solution)

private bool _isCheckedOne; private bool _isCheckedTwo; public bool IsCheckedOne { get { return _isCheckedOne; } set { SetProperty(ref _isCheckedOne, value); if (IsCheckedTwo == IsCheckedOne) { // prevent recursion IsCheckedTwo = !IsCheckedOne; } } } public bool IsCheckedTwo { get { return _isCheckedTwo; } set { SetProperty(ref _isCheckedTwo, value); if (IsCheckedOne == IsCheckedTwo) { // prevent recursion IsCheckedOne = !IsCheckedTwo; } } }

Hi, thanks for the answer both of you.

I try both, and it works for me.

@Wolf I tried the sample solution, but its target AGO 3.2 🙂

I changed the target in the daml-file and can run the souluton.

The attached solution (should work with 3.0) has two options: one with a code-behind implementation and one with a XAML based implementation that is using a value converter.
