我想使用ControlTemplate创建一个圆角按钮。这是我的代码，当我的宽度和高度等于30时，它能完美地工作。请问，是否可以将RadiusX和RadiusY设置为按钮width的一半（例如，RadiusX={width/2}）？
<ControlTemplate x:Key="RoundButton" TargetType="Button">
<Grid>
<Rectangle RadiusX="15" RadiusY="15"
Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"
Fill="{TemplateBinding Background}" />
<ContentPresenter Margin="3"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</ControlTemplate>
<ControlTemplate x:Key="RoundButton" TargetType="Button">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid x:Name="PART_Grid" Visibility="Hidden"/>
<Rectangle Grid.ColumnSpan="2"
RadiusX="{Binding ActualWidth, ElementName=PART_Grid, Mode=OneWay}"
RadiusY="{Binding ActualWidth, ElementName=PART_Grid, Mode=OneWay}"
Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"
Fill="{TemplateBinding Background}" />
<ContentPresenter Grid.ColumnSpan="2" Margin="3"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</ControlTemplate>
Width=“{TemplateBinding Width}”Height=“{TemplateBinding Height}”--这是多余的。最好移除。
