温度表(ProgressBar)无法工作

温度计(ProgressBar)无法工作
使用：

<ProgressBar x:Name="templateProgress" Template="{StaticResource templateThermometer}" Value="60" Minimum="0" Maximum="100"  Orientation="Vertical" Width="30" Height="280" Grid.Column="1"/>

设置Value值没反应！



模板：

<ControlTemplate x:Key="templateThermometer" TargetType="{x:Type ProgressBar}">
        <!-- Define two brushes for the thermometer liquid -->
        <ControlTemplate.Resources>
            <LinearGradientBrush x:Key="brushStem" StartPoint="0 0" EndPoint="1 0">
                <GradientStop Offset="0" Color="Red" />
                <GradientStop Offset="0.3" Color="Pink" />
                <GradientStop Offset="1" Color="Red" />
            </LinearGradientBrush>

            <RadialGradientBrush x:Key="brushBowl"  GradientOrigin="0.3 0.3">
                <GradientStop Offset="0" Color="Pink" />
                <GradientStop Offset="1" Color="Red" />
            </RadialGradientBrush>
        </ControlTemplate.Resources>

ControlTemplate被你改出问题了吧，视觉状态呢，怎么一个没有。

又不是交互控件，没有视觉状态也是允许的吧。

和交互不交互没关系，这控件默认的外观效果是由视觉状态控制的，楼主给删掉了，也看不错楼主这是什么平台(sl还是windowsphone RT)的进度指示器了，被改的面目全非。

想改的话，先去看看ProgressBar的默认模板吧。
用Blend生成一个就行了。
