Question

I have the following setup on a page within our WPF app. But cant get the selected gridview item. How can i do that with the following setup? I need the value in the # column

                <ListView Name="lbCase" ItemsSource="{Binding}" SelectionChanged="lbCase_SelectionChanged" SelectionMode="Single">
                    <ListView.View>
                        <GridView >
                            <GridViewColumn DisplayMemberBinding="{Binding Path=number}" >
                                <GridViewColumn.Header>
                                    <TextBlock Text="#" />
                                </GridViewColumn.Header>
                            </GridViewColumn>
                            <GridViewColumn DisplayMemberBinding="{Binding Path=name}" >
                                <GridViewColumn.Header>
                                    <TextBlock Text="Name" />
                                </GridViewColumn.Header>
                            </GridViewColumn>
                        </GridView>
                    </ListView.View>
                </ListView>

Can you use the SelectedItem property?

lbCase.SelectedItem?

In the selectionChanged event it is:

        private void lbCase_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            var lb = sender as ListBox;
            var current = lb.SelectedItem;
        }

Or you could change your bindings and bind the SelectedItem property to a property in code:

<Window x:Class="WpfApplication66.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" >

    <ListView Name="lbCase" ItemsSource="{Binding MyCollection}" SelectedItem="{Binding CurrentItem}" SelectionMode="Single">
        <ListView.View>
            <GridView >
                <GridViewColumn DisplayMemberBinding="{Binding Path=number}" >
                    <GridViewColumn.Header>
                        <TextBlock Text="#" />
                    </GridViewColumn.Header>
                </GridViewColumn>
                <GridViewColumn DisplayMemberBinding="{Binding Path=name}" >
                    <GridViewColumn.Header>
                        <TextBlock Text="Name" />
                    </GridViewColumn.Header>
                </GridViewColumn>
            </GridView>
        </ListView.View>
    </ListView>
    
</Window>

using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;

namespace WpfApplication66
{
    public partial class MainWindow : Window
    {
        public List<MyClass> MyCollection { get; set; }
        public MyClass CurrentItem { get; set; }

        public MainWindow()
        {
            InitializeComponent();
            MyCollection = new List<MyClass> { ... };
            DataContext = this;
        }
    }
}
