Question

现在我可以将按钮的外观更改为带有背景图像的椭圆。但是，当我点击它时，我感觉不到Silverlight中正常按钮的点击效果任何人都可以帮我解决这个问题吗？

这是圆形按钮的XAML样式

<style x:Key="roundButton" TargetType="Button">
    <Setter Properties="Template">
        <Setter.Value>
              <ControlTemplate TargetType="Button">
                 <Ellipse width="100" height="100">
                     <Ellipse.Fill>
                            <ImageBrush ImageSource="./icon.png">
                     </Ellipse.Fill>
                 </Ellipse>

              </ControlTemplate>
        </Setter.Value>
    </Setter>
</style>

搜索后我知道我应该在Systems.Window中使用VisualStateManager。这就是我的XAML现在的样子，但我仍然无法像正常按钮那样获得点击感觉

<Style x:Key="roundButton" TargetType="Button">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                    <Ellipse Width="100" Height="100">
                        <Ellipse.Fill>
                            <ImageBrush ImageSource="./icon.png" />
                        </Ellipse.Fill>
                    </Ellipse>

                    <vsm:VisualStateManager.VisualStateGroups>
                        <vsm:VisualStateGroup x:Name="CommonStates">
                            <vsm:VisualState x:Name="MouseOver"/>
                            <vsm:VisualState x:Name="Normal"/>
                            <vsm:VisualState x:Name="Pressed"/>
                            <vsm:VisualState x:Name="Disabled"/>
                        </vsm:VisualStateGroup>
                        <vsm:VisualStateGroup x:Name="FocusStates">
                            <vsm:VisualState x:Name="Unfocused"/>
                            <vsm:VisualState x:Name="Focused"/>
                        </vsm:VisualStateGroup>
                    </vsm:VisualStateManager.VisualStateGroups>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

您需要为相应状态设置按钮的触发器。

<style x:Key="roundButton" TargetType="Button">
    <Setter Properties="Template">
        <Setter.Value>
              <ControlTemplate TargetType="Button">
                 <Ellipse width="100" height="100">
                     <Ellipse.Fill>
                            <ImageBrush ImageSource="./icon.png"/>
                     </Ellipse.Fill>
                 </Ellipse>

                 <ControlTemplate.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                       <!-- mouse over look and feel here -->
                    </Trigger>
                    <Trigger Property="IsPressed" Value="True">
                       <!-- clicked look and feel here -->
                    </Trigger>
                    </ControlTemplate.Triggers> 
              </ControlTemplate>
        </Setter.Value>
    </Setter>
</style>

        <Setter Property="Template">

            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid>
                        <Ellipse Width="{TemplateBinding Width}" Height="{TemplateBinding Height}">
                            <Ellipse.Fill>
                                <RadialGradientBrush GradientOrigin=".2,.2">
                                    <GradientStop Offset="0.2" Color="White" />
                                    <GradientStop Offset="1" Color="Blue" />

                                </RadialGradientBrush>
                            </Ellipse.Fill>
                        </Ellipse>
                        <ContentPresenter Content="{TemplateBinding Content}" VerticalAlignment="Center" HorizontalAlignment="Center"/>
                    </Grid>
                </ControlTemplate>

            </Setter.Value>
        </Setter>

    </Style>

更简单的方法是使用Blend。拖放椭圆，将其转换为控件（按钮）。转到StatesTab相应地调整状态。通常，在按下状态下，应用缩放trasform以减小按钮大小，并使用translate transform将按钮（向下2px量）向下/向右移动就可以了。
