mutual exclusion checkboxes

Daniel4

Hi

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:

 <CheckBox
    Margin="5"
    Style="{DynamicResource Esri_CheckboxToggleSwitch}"
    Name="CheckBox_One"
    IsChecked="{Binding IsCheckedBoxOne}">
    <TextBlock>
    <Run Text="BoxOne"/>
    </TextBlock>                
    </CheckBox>

<CheckBox
     Margin="5"
     Style="{DynamicResource Esri_CheckboxToggleSwitch}"
     Name="CheckBox_Two"
     IsChecked="{Binding IsCheckedBoxTwo}">
     <TextBlock>
     <Run Text="BoxTwo"/>
     </TextBlock>
</CheckBox>

c#:

private bool _isCheckedBoxOne;
private bool _isCheckedBoxTwo;

public bool IsCheckedBoxOne
       {
         get { return _isCheckedBoxOne; }
         set
            {               
                SetProperty(ref _isCheckedBoxOne, value);               
             }
         }        

public bool IsCheckedBoxTwo
        {
            get { return _isCheckedBoxTwo; }
            set
            {
               SetProperty(ref _isCheckedBoxTwo, value);
            }
        }

 

How to implement the logic?

Wolf

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;
        }
      }
    }
