But in selection changed event we are making List_View_FooterMenu.SelectedItem = null;

thet why selection changed is hitting again and again?

There are 2 listviews in the application.

one listview below the other(like access menu)

there is a gap in center between the two list views.

if we click on that gap - selection changed event is firing..

we need to avoid that firing of selection changed event when we click somewhere else except item selection.

@Sunil A M, any update about this question? According to the Selector.SelectionChanged Event, it Occurs when the currently selected item changes.

@Sunil A M, as far as I'm concerned, the Selector.SelectionChanged Event shouldn't have this big impact issue and I still cannot reproduce. It's a long time since you asked the question. Have you solved this question?

cannot reproduce with the following code snippet. @Sunil A M, could you please show a minimal, reproducible sample without private information?

<ScrollViewer Width="500" Height="400">
    <StackPanel>
        <ListView SelectionChanged="ListView_SelectionChanged" Width="250">
