I'm using material design in XAML, I have a DataGrid, and when a row is selected and the mouse leaves the row then the row's background changes to white, if the mouse returns it changes back to the original color. 我想我已經找到了設定它的代碼部分，但我似乎無法覆寫它......這是'MaterialDesignDataGridCell'風格，對我來說似乎這設定了它。
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding IsSelected, RelativeSource={RelativeSource Self}}" Value="True"/>
<Condition Binding="{Binding IsMouseOver, RelativeSource={RelativeSource AncestorType=DataGridRow}}" Value="False" />
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="{DynamicResource MaterialDesignSelection}" />
</MultiDataTrigger>
我嘗試復制這個觸發器并設定一個不同的值，在滑鼠懸停時設定一個觸發器來設定背景，并嘗試設定這些但沒有運氣：
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Black" />
<SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Black" />
<SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="Black"/>
</Style.Resources>

不確定您要實作的目標，但是如果您想覆寫資料網格單元格的單元格樣式，您可以這樣做
<DataGrid>
<DataGrid.CellStyle>
<Style TargetType="DataGridCell" BasedOn="{StaticResource MaterialDesignDataGridCell}">
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding IsSelected, RelativeSource={RelativeSource Self}}" Value="True"/>
<Condition Binding="{Binding IsMouseOver, RelativeSource={RelativeSource AncestorType=DataGridRow}}" Value="False" />
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="Red" />
</MultiDataTrigger>
</Style.Triggers>
</Style>
</DataGrid.CellStyle>
</DataGrid>
