我如何在View模型中绑定StaticResource键

我有一个Canvas的不同ControlTemplates:

<Application.Resources>
    <ControlTemplate x:Key="Control1" />
    <ControlTemplate x:Key="Control2" />
</Application.Resources>

我想通过我的viewmodel属性更改其中一个:

private string _template = "Control1";
public string Template
        {
            get
            {
                return _template;
            }
            set
            {
                if (!string.IsNullOrEmpty(value))
                {
                    _template = value;
                    OnPropertyChanged("Template");
                }
            }
        }

最后在我看来使用它:

<UserControl Template="{StaticResource {Binding Template}}" />

但它不起作用,我怎么能解决它? 感谢

您可以尝试使用DataTriggers

<UserControl>
<UserControl.Style>
<Style TargetType="{x:Type UserControl}">
<Setter Property="ControlTemplate" value="{StaticResource Control1}"/>
<Style.Triggers>
<DataTrigger Binding="{Binding Template}" Value ="Control1">
<Setter Property="ControlTemplate" value="{StaticResource Control1}"/>
</DataTrigger>
<DataTrigger Binding="{Binding Template}" Value ="Control2">
<Setter Property="ControlTemplate" value="{StaticResource Control2}"/>
</DataTrigger>
</Style.Triggers>
</Style>
</UserControl.Style>
</UserControl>
