プロパティ情報から依存関係プロパティを直接変更すると、アプリケーションを実行するまでデザイン ビューにすぐに結果が表示されません。
<local:OnOffToggleButton HorizontalAlignment="Left" Margin="35,34,0,0" x:Name="onOffToggleButton1" VerticalAlignment="Top" StateOf4="3" GotFocus="onOffToggleButton1_GotFocus" Loaded="onOffToggleButton1_Loaded" />
public class OnOffToggleButton : Control// ToggleButton
{
public static readonly DependencyProperty StateOf4Property;
static OnOffToggleButton()
{
OnOffToggleButton.StateOf4Property = DependencyProperty.Register("StateOf4", typeof(int), typeof(OnOffToggleButton));
}
public int StateOf4
{
get
{
return (int)this.GetValue(OnOffToggleButton.StateOf4Property);
}
set
{
SetValue(OnOffToggleButton.StateOf4Property, value);
}
}
}
}
これが私のトグルボタンのデフォルト値、テンプレート、およびスタイルです
