How do I get the cell content value of the first column of the selected row of listview in WPF VB.NET?

Question

The XAML for my listview is given below:

<ListView Grid.Row="2" Name="ListView1" 
                  IsSynchronizedWithCurrentItem="True"
                  ItemsSource="{Binding Path={}}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="ID" DisplayMemberBinding="{Binding Path=ID}" Width="40"/>
                    <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}" Width="150"/>
                </GridView>
            </ListView.View>            
</ListView>

I want to get the value of the first column of the selected row when the row is double clicked. But how? I am using VS2010, VB. Please help me.

Hi,

You can do it like this

<Window x:Class="WpfApplicationListView.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300">
    <Grid>
        <StackPanel>
            <ListView Grid.Row="2" Name="ListView1" SelectionChanged="ListView1_SelectionChanged" PreviewMouseDoubleClick="ListView1_PreviewMouseDoubleClick"
                  IsSynchronizedWithCurrentItem="True"
                  ItemsSource="{Binding Path={}}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn Header="ID" DisplayMemberBinding="{Binding Path=ID}" Width="40"/>
                        <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}" Width="150"/>
                    </GridView>
                </ListView.View>
            </ListView>
        </StackPanel>
    </Grid>
</Window>
