How to prevent the double-click/single-click event from checking checkbox on a listview

Question

Hi,

I'm new with WPF (but not with C#) and I'm trying to use a Listview with checkboxes.
I successfully created a ListView with checkboxes on the first column but I would like the checkbox being checked only if I click on the column where the checkbox is and keep its state even if I click on a different row.
Normally if I click somewhere on a row, the row gets selected and the checkbox appears checked, if I select another row the previous line gets unselected and the previous checkbox gets unchecked.
If I double-click on a row (to let the user edit the row for example) the checkbox gets checked.
Is there a way to prevent this behaviour?
Thank you, regards.

If your CheckBox is bound to a property of an item (class), the CheckBox will not tick when the item is selected.

MainWindow.xaml:

<Grid>  
        <StackPanel >  
            <ListView Width="300" Height="300" ItemsSource="{Binding Datas}"    >  
                <ListView.View >  
                    <GridView AllowsColumnReorder="False">  
                        <GridViewColumn Header="Name" Width="120">  
                            <GridViewColumn.CellTemplate>  
                                <DataTemplate>  
                                    <TextBlock Text="{Binding Name}" TextWrapping="Wrap"/>  
                                </DataTemplate>  
                            </GridViewColumn.CellTemplate>  
                        </GridViewColumn>  
                        <GridViewColumn Header="Flag" Width="120">  
                            <GridViewColumn.CellTemplate>  
                                <DataTemplate>  
                                    <CheckBox   IsChecked="{Binding Path=Flag, Mode=TwoWay}"    Content="{Binding Path=Content,Mode=TwoWay}"/>  
                                </DataTemplate>  
                            </GridViewColumn.CellTemplate>  
                        </GridViewColumn>  
                    </GridView>  
                </ListView.View>  
            </ListView>  
        </StackPanel>  
    </Grid>  

MainWindow.xaml.cs:

using System.Collections.ObjectModel;  
using System.ComponentModel;  
using System.Runtime.CompilerServices;  
using System.Windows;  

namespace PreventCheckBoxInTheListView  
{  
  public partial class MainWindow : Window  
  {  
    ViewModel vm = new ViewModel();  
    public MainWindow()  
    {  
      InitializeComponent();  
      DataContext = vm;  
    }  
  }  
  public class ViewModel : INotifyPropertyChanged  
  {  
    ObservableCollection<Item> datas = new ObservableCollection<Item>();  
    public ObservableCollection<Item> Datas  
    {  
      get  
      {  
        return datas;  
      }  
      set  
      {  
        datas = value;  
        OnPropertyChanged("Datas");  
      }  
    }  
    public ViewModel()  
    {  
      datas.Add(new Item("name1", "content1", true));  
      datas.Add(new Item("name2", "content2", false));  
      datas.Add(new Item("name3", "content3", true));  
      datas.Add(new Item("name4", "content4", false));  
    }  
    public event PropertyChangedEventHandler PropertyChanged;  
    protected void OnPropertyChanged([CallerMemberName] string name = null)  
    {  
      PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));  
    }  
  }  
  public class Item  
  {  
    public string Name { get; set; }  
    public string Content { get; set; }  
    public bool Flag { get; set; }  
    public Item()  
    {  
    }  
    public Item(string name, string content,bool flag)  
    {  
      Name = name;  
      Flag = flag;  
      Content= content;  
    }  
  }  

}
