具体问题是如何继承我的自定义样式“Water”并覆盖其“Grid.Background”-Part？

有没有可能？首先，我只想在那里放另一张图片。

ButtonStyles1.xaml

您需要将模板绑定到外部属性，然后您的样式可以覆盖该属性。例子：

<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，模板绑定的属性的实际选择取决于您。Background在这种情况下使用它可能是有意义的。

您始终可以使用basedon属性，例如：

<Style x:Key="NewSytle" BasedOn="{StaticResource Water}">
  <Setter Property="Control.Background" Value="Blue"/>
</Style>
