只需将LinearGradientBrush资源上的
x:Shared
属性设置为false
。然后,每个矩形的“填充”属性都会获得指定的笔刷的副本
<LinearGradientBrush x:Key="ExecutionInitialization" x:Shared="false"
EndPoint="0.5,1" StartPoint="0.5,0">
...
</LinearGradientBrush>
然后,您还可以对所有此类矩形使用相同的事件处理程序:
<Rectangle x:Name="rec1" MouseDown="Rectangle_MouseDown" .../>
<Rectangle x:Name="rec2" MouseDown="Rectangle_MouseDown" .../>
private void Rectangle_MouseDown(object sender, MouseButtonEventArgs e)
{
var storyboard = TryFindResource("OnMouseLeftButtonDown1") as Storyboard;
storyboard.Begin((FrameworkElement)sender);
}
<Rectangle x:Name="rec1" MouseDown="Rectangle_MouseDown" .../>
<Rectangle x:Name="rec2" MouseDown="Rectangle_MouseDown" .../>
