Using Popups

Question

Can someone please explain to me, in idiot-level detail, how you are supposed to use the Popup and PopupManager classes?

But how do we use the PopupManager to access PopupMedia and PopupExpressions?

Popups are generally defined when creating your map, and defines how a feature should be displayed. Usually these are authored when publishing your webmap. You can think of the PopupManager as the ViewModel for the popup+feature instance. It helps you generate the view of the popup, formatting values for view etc. For instance a simple way to render the popup fields can be done like this: <ItemsControl ItemsSource="{Binding DisplayedFields}"> <DataTemplate> <StackPanel> <TextBox IsEnabled="false" Text="{Binding FormattedValue, Mode=OneWay}" BorderThickness="0" /> StackPanel> DataTemplate> ItemsControl>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ If you want to edit a feature, you could bind to the editable fields: <ItemsControl ItemsSource="{Binding EditableDisplayFields}"> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Field.Label}" FontWeight="Bold" /> <TextBox Text="{Binding Value, Mode=TwoWay}" BorderBrush="Red"> <Style TargetType="TextBox"> <Style.Triggers> {Binding ValidationError}" Value="{x:Null}"> "BorderBrush" Value="Black" /> Style> TextBox> StackPanel> DataTemplate> ItemsControl>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
