              VerticalAlignment="Top"
              Width="780"
              ItemsSource="{Binding}"
              IsSynchronizedWithCurrentItem="True"
               Margin="10,48,0,10">
    <ListView.View>
        <GridView>

            <GridView.Columns >
                <GridViewColumn>
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <CheckBox Tag="{Binding login_Id}"  />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn >
                <GridViewColumn Width="155px" DisplayMemberBinding="{Binding FirstName}" >
                    <GridViewColumn.Header>
                        <GridViewColumnHeader Tag="FirstName" Click="MenuItem_Click">User Name</GridViewColumnHeader>
                    </GridViewColumn.Header>
                </GridViewColumn>
                <GridViewColumn Width="155px" DisplayMemberBinding="{Binding Computer_Name}" Header="PC-Names" />
                <GridViewColumn Width="154px" DisplayMemberBinding="{Binding IP_Address}" Header="IP Adress" />
                <GridViewColumn Width="153px" DisplayMemberBinding="{Binding countID}">
                    <GridViewColumn.Header>
                        <GridViewColumnHeader Tag="countID" Click="MenuItem_Click">Documents Scanned</GridViewColumnHeader>
                    </GridViewColumn.Header>
                </GridViewColumn>
                <GridViewColumn Width="153px" DisplayMemberBinding="{Binding LogInTime}" >
                    <GridViewColumn.Header>
                        <GridViewColumnHeader Tag="LogInTime" Click="MenuItem_Click">Last Login</GridViewColumnHeader>
                    </GridViewColumn.Header>
                </GridViewColumn>
            </GridView.Columns>
        </GridView>
    </ListView.View>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

 I have tried, 

 

   private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
//Here How can I get id ?
        }
