I have 2 checkboxes. when one is checked, the other one must be checked and disabled. The code I have so far is like so

Xaml

<CheckBox x:Name="chkSABranches" Content="Apply to all branches" IsChecked="{Binding IsSABranches,ElementName=pgPageTemplate}" Grid.Row="0" Grid.Column="2"/>

In xaml.cs:

public static DependencyProperty IsSABranchesProperty = DependencyProperty.Register("IsSABranches", typeof(bool), typeof(pgAccounts), new PropertyMetadata(false));
        public static DependencyProperty IsSAWarehousesProperty = DependencyProperty.Register("IsSAWarehouses", typeof(bool), typeof(pgAccounts), new PropertyMetadata(false));

  public Boolean IsSABranches
        {
            get
            {
                return (bool)GetValue(IsSABranchesProperty);
            }
            set
            {
                SetValue(IsSABranchesProperty, value);
                NotifyPropertyChanged("IsSABranches");
                NotifyPropertyChanged("IsSAWarehouses");
            }
        }

 public Boolean IsSAWarehouses
        {
            get
            {
                return (bool)GetValue(IsSAWarehousesProperty) || (bool)GetValue(IsSABranchesProperty);
            }
            set
            {
                SetValue(IsSAWarehousesProperty, value);
                NotifyPropertyChanged("IsSAWarehouses");
            }
        }

This doesn't seem to work.. Could anyone please provide some guidance. thanks

C#

public Boolean IsSABranches
       {
           get
           {
               return (bool)GetValue(IsSABranchesProperty);
           }
           set
           {
               SetValue(IsSABranchesProperty, value);
if(value)
IsSAWarehouses = value;
               NotifyPropertyChanged("IsSABranches");
               
           }
       }

public Boolean IsSAWarehouses
       {
           get
           {
               return (bool)GetValue(IsSABranchesProperty);
           }
           set
           {
               SetValue(IsSAWarehousesProperty, value);
               NotifyPropertyChanged("IsSAWarehouses");
           }
       }

To make other check box disabled, eighter write down converter or another wrapper property to return negated value of IsSABranches.

Hope this will solve your problem.
