[英]WP7 - Control Template - unknown exception
I'm working through a beginners book to wp7 and in one of the basic tutorials I have been encountering an unknown exception. 我正在研究一本针对wp7的初学者书籍,在其中一个基本教程中,我遇到了一个未知异常。
The control template defined in the Application resources (App.xaml) file is as below. 在应用程序资源(App.xaml)文件中定义的控制模板如下。
<Application.Resources>
<Style x:Key="CustomButtonStyle" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<StackPanel>
<Image Source="Images\image.png" Width="200" Height="300" />
<TextBlock Text="{TemplateBinding Content}" TextAlignment="Center" />
</StackPanel>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Application.Resources>
Then when I create a button that uses this template eg 然后当我创建一个使用此模板的按钮时
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Button x:Name="CustomButton" Width="250" Height="350" Content="Custom Button" Style="{StaticResource CustomButtonStyle}" />
</Grid>
I always get a unknown exception raised. 我总是收到一个未知的异常。 I've narrowed it down to the 我把范围缩小到
Text="{TemplateBinding Content}"
Attribute in the control template but, why is there an exception? 控制模板中的属性,但是为什么会有异常? I have the content there, its in a string format. 我在那里有内容,它是字符串格式。 I don't know what else it may be? 我不知道还可能是什么? When I create a project I target Windows Phone 7.1. 创建项目时,我的目标是Windows Phone 7.1。 Was there some change I'm unaware of? 我不知道有什么变化吗? Any help is appreciated. 任何帮助表示赞赏。 Thanks Joe 谢谢乔
