How to allow check just single value ListView with checkboxes in WPF?

Question

I write a wpf application , using MVVM. I have a ListView of products names with checkboxes (binding by ObservableCollection).

<ListView ItemsSource="{Binding productsOfProject}" Margin="10">
                    <ListView.View>
                        <GridView>
                            <GridViewColumn >
                                <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <!--Command="{Binding CheckCommand}"-->
                                        <CheckBox IsChecked="{Binding IsChecked}">
                                            <i:Interaction.Triggers>
                                                <i:EventTrigger EventName="Click">
                                                    <i:InvokeCommandAction Command="{Binding ProductCheck}"/>
                                                </i:EventTrigger>
                                            </i:Interaction.Triggers>
                                        </CheckBox>
                                    </DataTemplate>
                                </GridViewColumn.CellTemplate>
                            </GridViewColumn>
                            <GridViewColumn DisplayMemberBinding="{Binding productName}" Header="Product Name" />
                        </GridView>
                    </ListView.View>
                </ListView>

Every product has an "IsChecked" property that updated according to the click.

I want to allow only one product to be marked. At each check, I call a function that marks the current checked value as unmarked, but still in the UI , the check is not cleared.

#region Event
        public ICommand productCheck;
        public ICommand ProductCheck
        {
            get
            {
                if (productCheck == null)
                {
                    productCheck = new RelayCommand(p => productCheckFunc());
                }
                return productCheck;
            }
        }

        private void productCheckFunc()
        {
            uncheckedProducts();
        }
        private void uncheckedProducts()
        {
            foreach (Product p in rvm.productsOfProject)
            {
                if (p.id != this.id)
                    p.IsChecked = false;
            }
        }
        #endregion Event

How can I access to the List View and unchecked to current checked value ?

Issue solved by using Radio Button instead of Combo Box. In radio button selecting one value is the default, we will only need to set one group.

Solution :

<ListView ItemsSource="{Binding productsOfProject}" Margin="10">
                    <ListView.View>
                        <GridView>
                            <GridViewColumn >
                                <GridViewColumn.CellTemplate>
                                    <DataTemplate>
                                        <RadioButton GroupName="One" IsChecked="{Binding IsChecked}">
                                            <i:Interaction.Triggers>
                                                <i:EventTrigger EventName="Click">
                                                    <i:InvokeCommandAction Command="{Binding ProductCheck}"/>
                                                </i:EventTrigger>
                                            </i:Interaction.Triggers>
                                        </RadioButton>
                                    </DataTemplate>
                                </GridViewColumn.CellTemplate>
                            </GridViewColumn>
                            <GridViewColumn DisplayMemberBinding="{Binding productName}" Header="Product Name" />
                        </GridView>
                    </ListView.View>
                </ListView>
