I have a ListView
with a binding to a ObservableCollection
. Further I am listing out all items in the ObservableCollection
. Now, Is there a good way to check if the ObservableCollection
is empty, and the display an alternative xaml?
You can use the HasItems dependency property of the ListView. With a trigger, when the property is false, you can change the ControlTemplate. Here is as example:
<ListView ItemsSource="{Binding Items}">
<ListView.Style>
<Style TargetType="{x:Type ListView}">
<Style.Triggers>
<Trigger Property="HasItems" Value="False">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListView}">
<Border SnapsToDevicePixels="true"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<TextBlock Text="No items"
HorizontalAlignment="Center"
VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
</Style>
</ListView.Style>
</ListView>
