推荐答案
您需要将模板绑定到外部属性，然后您的样式才能覆盖该属性.示例:
You need to have the template bind to an external property, then your style can override that property. Example:
<Style x:Key="Water" TargetType="Button">
<Setter Property="Background">
<Setter.Value>
<ImageBrush ImageSource="/WpfControlLibrary_Battleship;component/Resources/ButtonBackgrounds/Water.jpg"/>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Grid">
<Grid Background="{TemplateBinding Background}" ...
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="SomeOtherWaterStyle" BasedOn="{StaticResource WaterStyle" TargetType="Grid">
<Setter Property="Background" Value="Red"/>
</Style>
请注意，模板绑定的实际选择取决于您.在这种情况下使用Background可能很有意义.
Note that the actual choice of which property to template-bind is up to you. It probably makes sense to use Background in this instance.
