使用ResourceDictionary文件中的viewbox
本文关键字:viewbox 文件 ResourceDictionary 使用 | 更新日期: 2023-09-27 18:21:50
我有ResourceFile1.xaml文件其内容
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Viewbox x:Key="Flash-On" >
<Grid Width="256" Height="256" Visibility="Visible">
<Path Tag="Icon" Data="F1M376.251,632.755L385.665,632.755 381.302,646.07 394.618,646.07 389.11,660.302 393.01,660.302 381.531,672.93 377.398,660.763 381.073,660.763 383.829,652.268 369.825,652.268 376.251,632.755z" Stretch="Uniform" Fill="#FFFFFFFF" Width="176" Height="176" Margin="0,0,0,0" RenderTransformOrigin="0.5,0.5">
<Path.RenderTransform>
<TransformGroup>
<TransformGroup.Children>
<RotateTransform Angle="0" />
<ScaleTransform ScaleX="1" ScaleY="1" />
</TransformGroup.Children>
</TransformGroup>
</Path.RenderTransform>
</Path>
</Grid>
</Viewbox>
<Viewbox x:Key="Flash-Off">
....
</Viewbox>
</ResourceDictionary>
PhoneApplicationPage 的代码
<phone:PhoneApplicationPage.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ResourceFile1.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</phone:PhoneApplicationPage.Resources>
但是这个代码不起作用。设计器错误:InvalidOperationException:元素已经是另一个元素的子元素。也是<Button Content="{StaticResource Flash-On}"/>
如果我使用类似的代码运行时错误:未能分配给属性"System.Windows.Controls.ContentControl.Content"。如果viewbox在Grid.Resources中使用,没有问题,但我想与ResourceDictionary一起使用。我该怎么办?
DataTemplate
:
<DataTemplate x:Key="ButtonTemplate">
<Viewbox>
<!-- Here your content-->
</Viewbox>
</DataTemplate>
<Button ContentTemplate="{StaticResource ButtonTemplate}"/>
更新0
我写了一个例子,根据CheckBox
的值更改模板。
更改模板的转换器:
public class TemplateSelectorConverter : IValueConverter
{
public DataTemplate TrueTemplate { get; set; }
public DataTemplate FalseTemplate { get; set; }
public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
if (((bool) value))
return TrueTemplate;
return FalseTemplate;
}
public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
资源:
<DataTemplate x:Key="FirstTemplate">
<TextBox Text="FirstTemplate" />
</DataTemplate>
<DataTemplate x:Key="SecondTemplate">
<TextBox Text="SecondTemplate" />
</DataTemplate>
<internal:TemplateSelectorConverter x:Key="TemplateSelector" TrueTemplate="{StaticResource FirstTemplate}"
FalseTemplate="{StaticResource SecondTemplate}" />
Xaml标记:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="30" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<CheckBox Name="CheckBox"/>
<Button Grid.Column="1"
ContentTemplate="{Binding Path=IsChecked, ElementName=CheckBox, Converter={StaticResource TemplateSelector}}"
VerticalAlignment="Top" />
</Grid>
我希望这能有所帮助。
