以前的方案

以前写过一个圆点绕圈的进度条，主要是在cs文件中动态添加圆点，通过定时器设置角度后，用正弦余弦设置(x,y)的位置。

此方案优点：不需要UI图标

此方案缺点：定时器耗性能

现在的方案

如果有UI图标，或者自己能够设计矢量图的情况下，可以通过Xaml实现绕圈动画的设置。如下图

添加矢量-Geometry图标

首先通过矢量设计工具，编辑并生成一个绕圈的进度图标（含有8个Path),得到8个StreamGeometry。

比如下面的24*24的图标：

透明度：将8个顺时针的Path添加Geometry Data，不透明度由小到大设置。
填充色：可在cs文件中添加依赖属性ForegroundBrush，构造函数中设置DataContent=this，然后Path直接绑定此依赖属性ForegroundBrush值即可。

添加绕圈动画

1. 设置一个主动改变透明度的动画静态资源Storyboard.Circle。间隔时间，如0.8秒内，8个path均循环改变其的透明度，从而达到绕圈的效果

2. 触发和暂停绕圈动画

通过一个属性IsActive，来触发动画是否启动和停止。

StopStoryboard可以将当前的动画停止，用法：BeginStoryboardName="XXX"

除了StopStoryboard，BeginStoryboard，还有其它Storyboard类，可以顺带了解一下。

ResumeStoryboard
BeginStoryboard
PauseStoryboard

 1 DataTrigger Binding="{Binding IsActive}" Value="True">
 2     DataTrigger.EnterActions>
 3         BeginStoryboard Name="LoadingBeginStoryboard" Storyboard="{StaticResource Storyboard.Circle}"/>
 4     DataTrigger.EnterActions>
 5 DataTrigger>
 6 DataTrigger Binding="{Binding IsActive}" Value="False">
 7     DataTrigger.EnterActions>
 8         StopStoryboard BeginStoryboardName="LoadingBeginStoryboard" />
 9     DataTrigger.EnterActions>
10 DataTrigger>

另：我们可以通过设置具体的加载尺寸，来设置Loading的显示大小。如32*32，64*64

可以在cs文件中添加个依赖属性LoadingSize，然后通过设置DataContext=this，xmal中直接可以根据绑定的LoadingSize改变样式。

 1 ControlTemplate.Triggers>
 2     DataTrigger Binding="{Binding LoadingSize}" Value="{x:Static controls:LoadingSize.Size32}">
 3         Setter TargetName="RootGrid" Property="Width" Value="32"/>
 4         Setter TargetName="RootGrid" Property="Height" Value="32"/>

使用ContentControl来呈现，在ContentControl的模板中设置Loading内容。例如：

ContentControl x:Name="LoadingContent" Template="{StaticResource Template.Loading}"/>

替代方案

以上是在图标位置不变化的情况下设置透明度实现的，如果需要简单点的实现方式或者整体绕圈旋转效果，可以设置

1. ContentControl的模板内容为一张完整图片Image或者DrawingImage

2. 添加ContentControl的旋转RotateTransform

1 ContentControl.RenderTransform>
2     RotateTransform x:Name="LoadingContentRotateTransform"/>
3 ContentControl.RenderTransform>

3. 添加动画

触发条件trigges设置，可参考上面的依赖属性绑定。

1 Storyboard x:Key="Storyboard.Circle" RepeatBehavior="Forever">
2     DoubleAnimation Storyboard.TargetName="LoadingContentRotateTransform" Storyboard.TargetProperty="Angle" From="0" To="360" Duration="0:0:0.8"/>
3 Storyboard>
