Assigning Style resources to a DataGrid
提问by David Coorey
Apologies for the maybe hazy nature of this question, but I am fairly new to WPF and am consequently struggling with the issue of resources.
为这个问题的模糊性质道歉，但我对 WPF 相当陌生，因此我正在努力解决资源问题。
My problem is that I have a DataGridthat I wish to assign a style to that describes properties such as the FontSizeand Background/Foregroundcolours (when the mouse hovers over the rows). I can do this successfully as follows:
我的问题是我有一个DataGrid我希望分配一个样式来描述FontSize和Background/Foreground颜色等属性（当鼠标悬停在行上时）。我可以成功地做到这一点如下：
<Window x:Class="WpfApplication11.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<DataGrid Name="DataGrid1" ItemsSource="{Binding Path=Fibers}">
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="FontSize" Value="12"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Blue"/>
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.RowStyle>
<DataGrid.Columns>
<DataGridTextColumn Header="FiberNo" />
<DataGridTextColumn Header="Fiber" />
<DataGridTextColumn Header="Connection" />
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>
But I know/hope that there must be a way to define this RowStyleas a separate resource, and then refer to this resource (via a name) from within the DataGriddefinition itself. I therefore have tried creating a Window.Resourcestag and a tag within the DataGridthat refers to it.
但我知道/希望必须有一种方法将它定义RowStyle为一个单独的资源，然后从DataGrid定义本身中引用这个资源（通过名称）。因此，我尝试Window.Resources在DataGrid引用它的 中创建一个标签和一个标签。
Please see below:
请参阅以下内容：
<Window x:Class="WpfApplication11.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<DataGrid x:Key="MyDataGridStyle">
<DataGrid.RowStyle>
<Style TargetType="DataGridRow">
<Setter Property="FontSize" Value="12"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Blue"/>
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
</Style>
</DataGrid.RowStyle>
</DataGrid>
</Window.Resources>
<Grid>
<DataGrid Name="DataGrid1" ItemsSource="{Binding Path=Fibers}">
<StaticResource ResourceKey="MyDataGridStyle"/>
<DataGrid.Columns>
<DataGridTextColumn Header="FiberNo" />
<DataGridTextColumn Header="Fiber" />
<DataGridTextColumn Header="Connection" />
</DataGrid.Columns>
</DataGrid>
</Grid>
</Window>
Needless to say that this does not work. It doesn't crash, but I am not seeing any rows, either. The code I have supplied here is a scaled-down version of what I have written for my application, but the essentials are the same.
不用说，这行不通。它不会崩溃，但我也没有看到任何行。我在此处提供的代码是我为应用程序编写的代码的缩小版本，但基本要素是相同的。
Regards, David.
问候，大卫。

EDIT: did not look carefully on your code... :) so for completeness
编辑：没有仔细查看您的代码... :) 所以为了完整性
<Window.Resources>
<Style x:Key="MyDataGridStyle" TargetType="DataGridRow">
<Setter Property="FontSize" Value="12"/>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="Blue"/>
<Setter Property="Foreground" Value="White"/>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<DataGrid Name="DataGrid1"
ItemsSource="{Binding Path=Fibers}"
RowStyle="{StaticResource MyDataGridStyle}" ...>
