c# - WPF ListView SelectedItem is null

Question

I have a Listview that has a checkbox as one of the columns. If I click anywhere but the actual checkbox the SelectedItem of the ListView is set to the current selected row, as expected. If, on the other hand I click onto the checkbox (without clicking on the row first) then the SelectedItem is null or the previously clicked row.

Can anyone help me out....

Cheers

<ListView Width="auto" SelectionMode="Single" x:Name="listBox"  ItemsSource="{Binding MyData}" SelectedItem="{Binding Path=SelectedMyData}">

It's very easy, just handle Click event on your checkbox:

private void CheckBox_Click(object sender, RoutedEventArgs e) {
    var cb = sender as CheckBox;
    var item = cb.DataContext;
    myListView.SelectedItem = item;
}
