A collection of Setter and EventSetter objects. The default is an empty collection.

Examples

The following example shows how to use this property.

Style style = new Style(typeof(ListBoxItem));
style.Setters.Add(new Setter(ListBoxItem.HorizontalContentAlignmentProperty,
     HorizontalAlignment.Stretch));
ListBox lb = new ListBox();
lb.ItemContainerStyle = style;
ListBoxItem lbi1 = new ListBoxItem();
Button btn = new Button();
btn.Content = "Button as styled list box item.";
lbi1.Content = (btn);
lb.Items.Add(lbi1);

Dim style As Style = New Style()
style.Setters.Add(New Setter(ListBoxItem.HorizontalContentAlignmentProperty, _
     HorizontalAlignment.Stretch))
Dim lb As ListBox = New ListBox()
lb.ItemContainerStyle = style
Dim lbi1 As ListBoxItem = New ListBoxItem()
Dim btn As Button = New Button()
btn.Content = "Button as styled list box item."
lbi1.Content = (btn)
lb.Items.Add(lbi1)

Adding a SetterBase child to a Style object implicitly adds it to the SetterBaseCollection for the Style object. The following EventSetter is implicitly added to the SetterBaseCollection of the style:

<StackPanel
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
  x:Class="SDKSample.EventOvw2"
  Name="dpanel2"
  Initialized="PrimeHandledToo"
>
  <StackPanel.Resources>
    <Style TargetType="{x:Type Button}">
      <EventSetter Event="Click" Handler="b1SetColor"/>
    </Style>
  </StackPanel.Resources>
  <Button>Click me</Button>
  <Button Name="ThisButton" Click="HandleThis">
    Raise event, handle it, use handled=true handler to get it anyway.
  </Button>
</StackPanel>

Remarks

The Setters property of a Style object can consist only of objects assignable to SetterBase. Adding a SetterBase child to a Style object implicitly adds it to the SetterBaseCollection for the Style object.

An explicit property element usage for Setters is also relatively common. This is a markup style decision that can sometimes help distinguish Setters from Resources and Triggers items in a complex style. For example:

<Style>
  <Style.Setters>
    <!--one or more SetterBase derived object elements here-->
  </Style.Setters>
</Style>

XAML Property Element Usage

<object>
  oneOrMoreSetters
</object>

XAML Values

oneOrMoreSetters One or more Setter or EventSetter objects.
