C# Change backgroundcolor specific row
提问by user1951083
I've created a new project from the Grid App (XAML) template (C# Windows Store). So far I've changed nothing in the template, but I would like to change the backgroundcolor from a specific row in the grid.
我从 Grid App (XAML) 模板（C# Windows Store）创建了一个新项目。到目前为止，我没有更改模板中的任何内容，但我想更改网格中特定行的背景颜色。
<!--
This grid acts as a root panel for the page that defines two rows:
* Row 0 contains the back button and page title
* Row 1 contains the rest of the page layout
-->
<Grid Style="{StaticResource LayoutRootStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
I would like to change the backgroundcolor from row 0 (which contains the page title). Any ideas?? Thanks in advance!
我想从第 0 行（包含页面标题）更改背景颜色。有任何想法吗？？提前致谢！
This row consits of:
该行包括：
<!-- Back button and page title -->
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Button x:Name="backButton" Click="GoBack" IsEnabled="{Binding Frame.CanGoBack, ElementName=pageRoot}" Style="{StaticResource BackButtonStyle}"/>
<TextBlock x:Name="pageTitle" Text="{StaticResource AppName}" Grid.Column="1" IsHitTestVisible="false" Style="{StaticResource PageHeaderTextStyle}"/>
</Grid>

You can't set the background color on the Grid.Row itself, instead set the Background property on whatever occupies this row.
您不能在 Grid.Row 本身上设置背景颜色，而是在占据该行的任何内容上设置背景属性。
For example
例如
<Grid Style="{StaticResource LayoutRootStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Grid Background="Red" Grid.Row="0">
<TextBlock>Test</TextBlock>
</Grid>
</Grid>
EDIT: Updated for Silverlight; TextBlock doesn't have Background so you have to put the control in another Border or grid container which does have background. Code updated to reflect this.
编辑：为 Silverlight 更新；TextBlock 没有背景，因此您必须将控件放在另一个有背景的边框或网格容器中。代码更新以反映这一点。

How about inserting border where you need it
如何在需要的地方插入边框
<Grid Style="{StaticResource LayoutRootStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Border Background="Red" Grid.ColumnSpan="1"></Border>
<TextBlock>Test</TextBlock>
<Border Background="blue" Grid.Row="1" Grid.ColumnSpan="1"></Border>
<TextBlock Grid.Row="1">Test2</TextBlock>
</Grid>
note that you can especify the columns span in case of include more columns
请注意，如果包含更多列，您可以指定列跨度
