带有多个文本块的 Windows 7 Phone 按钮
我通过编辑其样式在 Blend 中创建了一个按钮。我添加了多个文本块,目的是向用户实时显示数据。但是,我不知道如何与后面的代码中的这些文本块进行交互。
我的样式 XAML 是这样的:
<ControlTemplate TargetType="Button">
<Grid Background="Transparent">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="ButtonBackground" BorderThickness="{TemplateBinding BorderThickness}" Background="{StaticResource PhoneAccentBrush}" CornerRadius="0" Margin="8,12,12,12">
<TextBlock Margin="121,5,98,0" TextWrapping="Wrap" Text="Current Program:" Height="36" VerticalAlignment="Top"/>
</Border>
<TextBlock Margin="92,68,80,81" TextWrapping="Wrap" Text="" RenderTransformOrigin="0.265,0.51" HorizontalAlignment="Center" Width="271" x:Name="programName"/>
<TextBlock Height="32" Margin="21,0,16,12" TextWrapping="Wrap" Text="Date:" VerticalAlignment="Bottom" x:Name="CurrentDate"/>
</Grid>
</ControlTemplate>
我显示按钮的代码是这样的:
<Grid x:Name="middleRow" Grid.Row="2">
<Button Content="Button" Margin="8,8,0,8" Style="{StaticResource ButtonCenter}" x:Name="Current" Click="Current_Click" d:LayoutOverrides="GridBox" />
</Grid>
在我的代码后面的 InitializeComponent(); 之后我想更改 ProgramName 文本块和 CurrentDate 文本块。
我想我可能必须创建一个控件来执行此操作,但我不确定。我的尝试失败了(杂项错误)。我可以在代码中访问这些文本块吗?请告诉我。
更新:
我最终这样做了:
<Button Margin="8,8,0,8" x:Name="Current" Click="Current_Click">
<Button.Content>
<StackPanel>
<TextBlock x:Name="ProgramName" Text="program name" HorizontalAlignment="Center" />
<TextBlock x:Name="CurrentDate" Text="current date" HorizontalAlignment="Center" />
</StackPanel>
</Button.Content>
</Button>
我在 Blend 中应用了模板中的样式,它现在似乎正在工作。
I have created a button in Blend by editing it's style. I added multiple text blocks with the intention of displaying data to the user in real time. However, I don't know how to interface with those text blocks in my code behind.
My Style XAML is this:
<ControlTemplate TargetType="Button">
<Grid Background="Transparent">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed"/>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="ButtonBackground" BorderThickness="{TemplateBinding BorderThickness}" Background="{StaticResource PhoneAccentBrush}" CornerRadius="0" Margin="8,12,12,12">
<TextBlock Margin="121,5,98,0" TextWrapping="Wrap" Text="Current Program:" Height="36" VerticalAlignment="Top"/>
</Border>
<TextBlock Margin="92,68,80,81" TextWrapping="Wrap" Text="" RenderTransformOrigin="0.265,0.51" HorizontalAlignment="Center" Width="271" x:Name="programName"/>
<TextBlock Height="32" Margin="21,0,16,12" TextWrapping="Wrap" Text="Date:" VerticalAlignment="Bottom" x:Name="CurrentDate"/>
</Grid>
</ControlTemplate>
My code to display the button is this:
<Grid x:Name="middleRow" Grid.Row="2">
<Button Content="Button" Margin="8,8,0,8" Style="{StaticResource ButtonCenter}" x:Name="Current" Click="Current_Click" d:LayoutOverrides="GridBox" />
</Grid>
In my code behind after the InitializeComponent(); I would like to change the ProgramName text block and the CurrentDate text block.
I'm thinking that I might have to create a control to do this but I'm not sure. My attempts at doing so failed (misc. errors). Can I access these text blocks in code? Please let me know.
UPDATE:
I wound up doing it like this:
<Button Margin="8,8,0,8" x:Name="Current" Click="Current_Click">
<Button.Content>
<StackPanel>
<TextBlock x:Name="ProgramName" Text="program name" HorizontalAlignment="Center" />
<TextBlock x:Name="CurrentDate" Text="current date" HorizontalAlignment="Center" />
</StackPanel>
</Button.Content>
</Button>
I applied my styles from the template in Blend and it appears to be working now.

您不能按名称引用样式中的控件,因为页面上可能有它们的多个副本。
如果您将按钮制作为自定义控件,则可以为 ProgramTitle 和 CurrentDate 属性制作文本(这将非常容易设置)。
或者,您可以使用数据绑定来设置这些值。
You can't reference controls in a style by name as there could be multiple copies of them on a page.
If you made your button into a custom control you could make the text for the ProgramTitle and CurrentDate properties (which woudl be very easy to set).
Alternatively you could use databinding to set these values.
