带有GridView WPF的多行和单行选择列表视图

Question

I have a question regarding wpf and ListView s. I have this program code in my Windows.xaml

 <Grid>
    <ListView Margin="10" Name="lvUsers">
        <ListView.View>
            <GridView>
                <GridViewColumn Header="Names" Width="140" DisplayMemberBinding="{Binding Name}" />
                <GridViewColumn Header="Telefon" Width="60" DisplayMemberBinding="{Binding Age}" />
                <GridViewColumn Header="Adress" Width="180" DisplayMemberBinding="{Binding Mail}" />
            </GridView>
        </ListView.View>
    </ListView>

And in my Windows.xaml.cs i have this code

public partial class ListViewGridViewSample : Window
{
    public ListViewGridViewSample()
    {
        InitializeComponent();
        List<User> items = new List<User>();
        items.Add(new User() { Name = "molo", Telefon= 0909090, Adress= "Street" });
        items.Add(new User() { Name = "moloi", Telefon="99999", Adress= "street2" });
    }
}

And my question is, when I execute this program code I get a window with a ListView . And now I want to make a selection at a single or multiple rows. Maybe I want to select row number two this would be the User moloi and after selecting this row I want to pass on to a message box for example. How can I handle that?

Can someone give me an easy example pls

thank you all

ListView has a property called SelectionMode="Extended" . That will allow you to set the desired selection mode. To make the selection behavior, you can use SelectionChanged event that is also available on the ListView . these two things can help you achieve everything you stated above.

<ListView Name="lvUsers"
          ItemsSource="{Binding}"
          Margin="10"
          SelectionMode="Extended"
          SelectionChanged="lvUsers_SelectionChanged">
  <ListView.View>

And the code behind for the event:

private void lvUsers_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    //e.AddedItems - these are the items that have currently been selected
}
