I am using a ListView and I want to disable the selected item when I click anywhere in the UI or click another control in the UI.
<ListView x:Name="View" Grid.Row="1" Grid.Column="0" ItemsSource="{Binding View}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" IsSynchronizedWithCurrentItem="True" SelectedItem="{Binding Contact}" SelectionMode="Single">
Hi SYarah,
you can use an attached property in ContactListingViewModel:
<ListView Grid.Row="1" Grid.Column="0"
ItemsSource="{Binding View}"
ScrollViewer.HorizontalScrollBarVisibility="Disabled"
IsSynchronizedWithCurrentItem="True"
SelectedItem="{Binding Contact}"
local:ContactListingViewModel.AttPropListView="True">
...
#region attached property
public static readonly DependencyProperty AttPropListViewProperty =
DependencyProperty.RegisterAttached("AttPropListView", typeof(bool), typeof(ContactListingViewModel), new PropertyMetadata(false, OnPropChanged));
public static bool GetAttPropListView(DependencyObject obj) => (bool)obj.GetValue(AttPropListViewProperty);
public static void SetAttPropListView(DependencyObject obj, bool par) => obj.SetValue(AttPropListViewProperty, par);
private static void OnPropChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
ListView lv = d as ListView;
if (lv == null) return;
lv.PreviewMouseLeftButtonDown += (s, mbe) =>
{
ContactListingViewModel vm = (ContactListingViewModel)(lv.DataContext);
vm.Contact = null;
vm.OnPropertyChanged(nameof(Contact));
};
}
#endregion
Result:
Hi, Please read the question more carefully. It should work for click on blank space in the ListView or on any other control in UI. Your suggestion works only for clicking on ListView. If I click on other control in UI it does not work.
Hi Sarah,
which problem you have to use my solution in window? If you click "on other control in UI" click to "edit" or "Delete" reset the selection too! What do you want to do?

Hi,When clicking on white spaces (for example under the Delete button) or in the TextBox, your solution does not work.
