我在App.xaml文件中定义了一个样式:
<Style x:Key="TileListBoxItemStyle" TargetType="ListBoxItem">
<Setter Property="Padding" Value="0"/>
<Setter Property="Margin" Value="12,12,0,0"/>
<Setter Property="Background" Value="{StaticResource PhoneAccentBrush}"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="Width" Value="210"/>
<Setter Property="Height" Value="210"/>
<!--<Setter Property="HorizontalAlignment" Value="Left"/>-->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid>
<Rectangle Fill="{TemplateBinding Background}"/>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
现在我需要在PhoneApplicationPage XAML文件中使用Binding更改Background属性:
<UserControl.Resources>
<Style x:Key="TileListBoxItemStyle2" TargetType="ListBoxItem" BasedOn="{StaticResource TileListBoxItemStyle}">
<Setter Property="Background" Value="{Binding Color}" />
</Style>
</UserControl.Resources>
抛出以下异常:
{System.Windows.Markup.XamlParseException: Failed to assign to property 'System.Windows.Setter.Value'. [Line: 23 Position: 49] ---> System.NotSupportedException: Cannot set read-only property ''.
at MS.Internal.XamlMemberInfo.SetValue(Object target, Object value)
at MS.Internal.XamlManagedRuntimeRPInvokes.SetValue(XamlTypeToken inType, XamlQualifiedObject& inObj, XamlPropertyToken inProperty, XamlQualifiedObject& inValue)
虽然我在网上搜索它似乎不起作用,但这可能不起作用,但也许Windows Phone有限制?
答案 0 :(得分:3)
Windows手机中的Style setter中无法绑定,但article可以帮助您。 否则,我看到你唯一能做的就是创建一个继承ListBox的类,或者在GetContainerForItemOverride中创建,并在代码中创建绑定。
