当我在宽度为 120 的网格内使用进度条（IsIndertiminate=true）时，进度条动画看起来很奇怪。进度点似乎并排移动，它们之间没有任何适当的间距。此外，由于这个（宽度更小），点分别在开始和结束时移开/靠近的效果不太明显。
那么，当我以有限的宽度显示进度条时，如何使进度条看起来更好。我尝试自己搜索并更改progressBar的属性，但无法达到令人满意的状态。
编辑：在我的 grid.row 中，通过将我的 progressBar 的宽度设置为“自动”，我能够实现理想的间距/外观（它仍然不完美，但对我有用）。
它只需要对该控件Style Template进行一些自定义，以对充当ProgressBar自身的形状进行一些调整。
目前我面前没有 WP7 ProgressBar 的默认样式模板，但是如果您在 Expression Blend 中打开您的项目，请右键单击它并选择“编辑模板 -> 编辑副本（或编辑原始文件）要公开样式模板，您会看到形状，我认为甚至驱动它的情节提要动画也准备好根据您的心愿进行编辑。
如果您提供默认模板的副本，我相信如果您自己没有得到它，我们可以很快为您提供解决方案。希望这可以帮助 ：）
进度条默认样式，每个矩形都可以修改！

例如，只需设置Widht = "2" Height = "2"可能就是您需要的！
<Rectangle x:Name="R1" CacheMode="BitmapCache" Fill="{TemplateBinding Foreground}" Height="2" IsHitTestVisible="False" Opacity="0" Width="2">
您还可以使用任何形状，而不仅仅是矩形。不要忘记为您的 ProgresBar 分配此样式。
希望它的帮助。
