How to notify the selection changed in WinUI SfComboBox?

In this article, WinUI ComboBox can get the notification of the selection change using the event SelectionChanged. This event contains the newly selected and removed items in the AddedItems and RemovedItems properties. Let’s look at the property details.

• AddedItems - Contains the items that were selected.
• RemovedItems - Contains the items that were unselected.

XAML:

<editors:SfComboBox x:Name="comboBox"
                   Width="250"
                   TextMemberPath="Name"
                   DisplayMemberPath="Name"
                   ItemsSource="{Binding SocialMedias}"
                   SelectionChanged="OnComboBoxSelectionChanged" />

The SelectionChanged event can be handled as follows.

C#

private async  void OnComboBoxSelectionChanged(object sender, ComboBoxSelectionChangedEventArgs e)
{
  	 var cd = new ContentDialog
   	  {
       Content = "Selected item was changed.",
       CloseButtonText = "Close"
   };

   cd.XamlRoot = this.Content.XamlRoot;
   var result = await cd.ShowAsync();
}
