XAML为Map PushPin创建PushPin

Question

我试图自定义一个地图图钉模板。不是windows 8手机，这只是一个WPF地图控件。我无法让XAML识别TargetType。我必须指定TargetType，以便修改在泛型控件中找不到的某些元素。我试过几种变体。该代码存在于与WPF UserControl分离的XAML文件中(在MergedDictionaries中引用)。代码如下：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:m="clr-namespace:Microsoft.Maps.MapControl.WPF;assembly=Microsoft.Maps.MapControl.WPF">

    <ControlTemplate x:Key="PushPinTemplate" TargetType="m:PushPin" >
        <Grid x:Name="ContentGrid">
            <StackPanel Orientation="Vertical">
                <Grid Background="{TemplateBinding Background}"
                                                HorizontalAlignment="Left"
                                                MinHeight="31"
                                                MinWidth="29">
                    <ContentPresenter HorizontalAlignment="Center"
                                               Content="{TemplateBinding Content}"
                                               ContentTemplate="{TemplateBinding ContentTemplate}"
                                               Margin="4"/>
                </Grid>
                <Polygon Fill="{TemplateBinding Background}"
                                                             Points="0,0 29,0 0,29"
                                                             Width="29"
                                                             Height="29"
                                                             HorizontalAlignment="Left"/>
            </StackPanel>
        </Grid>
    </ControlTemplate>
</ResourceDictionary>

在PushPin.Template中设置C#

pushpin.Template = (ControlTemplate)(Resources["PushPinTemplate"]);

Answer 1

类型名称未正确写入。这是Pushpin，而不是PushPin

<ControlTemplate ... TargetType="m:Pushpin">

Answer 2

您错过了{x:Type }声明

<ControlTemplate x:Key="PushPinTemplate" TargetType="{x:Type m:PushPin}" >

这意味着您要向TargetType提供字符串，而不是类型

x:Type标记扩展为接受类型类型的属性提供了从字符串转换行为。输入是XAML类型。
