C＃变化的backgroundColor特定行 [英] C# Change backgroundcolor specific row

问题描述

我创建从电网应用（XAML）模板（C＃Windows应用商店）的新项目。
到目前为止，我什么也没有改变模板，但我想给的backgroundColor在网格中的特定行更改。

 < ！code><  -  
此网格作为一个根面板定义两行的页面：
 *行0包含后退按钮和页面标题
 *第1行包含页面布局
的其余部分 - > 
<网格样式={StaticResource的LayoutRootStyle}> 
< Grid.RowDefinitions> 
< RowDefinition HEIGHT =140/> 
< RowDefinition高度=*/> 
< /Grid.RowDefinitions> 
  

我想从0更改行的backgroundColor（其中包含页面标题）。
任何想法？ ！在此先感谢

这行consits：

 < ！ - 后退按钮和页面标题 - > 
<网格和GT; 
< Grid.ColumnDefinitions> 
< ColumnDefinition WIDTH =自动/> 
< ColumnDefinition WIDTH =*/> 
< /Grid.ColumnDefinitions> 
<按钮X：NAME =后退按钮点击=GoBack的IsEnabled ={结合Frame.CanGoBack，的ElementName = pageRoot}风格={StaticResource的BackButtonStyle}/> 
< TextBlock的X：名称=PAGETITLE文本={StaticResource的AppName}是Grid.Column =1IsHitTestVisible =false的风格={StaticResource的PageHeaderTextStyle}/> 
< /网格和GT; 
  

解决方案

您不能设置对电网的背景颜色.Row本身，而不是设置任何占据此行的背景属性。

例如

 <网格样式={StaticResource的LayoutRootStyle}> 
< Grid.RowDefinitions> 
< RowDefinition HEIGHT =140/> 
< RowDefinition高度=*/> 
< /Grid.RowDefinitions> 
<网格背景=红Grid.Row =0> 
<&的TextBlock GT;测试与LT; / TextBlock的> 
< /网格和GT; 
< /网格和GT; 
  

编辑：
更新了Silverlight的; TextBlock的没有背景，所以你必须把另一边界或网格容器里面确实有背景的控制。代码更新，以反映这一点。

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.

<!--
    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!

This row consits of:

    <!-- 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>

解决方案

You can't set the background color on the Grid.Row itself, instead set the Background property on whatever occupies this row.

For example

<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.
