Question

我在WPF中有样式资源，所以在我的App.xaml中我可以定义是否使用了客户或管理员布局。这很好地通过以类似HTML / CSS的方式从主XAML中获取所有样式。

现在如何制作这个动态，以便点击我的应用程序中的按钮，并在运行时在客户和管理员之间切换布局？

感谢Meeh的链接，所以我做了这个，当我调试时，它逐步完成所有行，但仍然没有改变布局，我还需要做什么，以便布局在运行时更改？

private void Button_Switch_Layout_Click(object sender, RoutedEventArgs e)
{
    string layoutIdCode = "administrator";

    switch (layoutIdCode)
    {
        case "administrator":
            langDictPath = "Resources/AdministratorLayout.xaml";
            break;

        case "customer":
            langDictPath = "Resources/CustomerLayout.xaml";
            break;
    }

    Uri langDictUri = new Uri(langDictPath, UriKind.Relative);
    ResourceDictionary langDict = Application.LoadComponent(langDictUri) as ResourceDictionary;
    Application.Current.Resources.MergedDictionaries.Clear();
    Application.Current.Resources.MergedDictionaries.Add(langDict);
}

</ResourceDictionary>

Answer 1

您需要在Window1.xaml中使用DynamicResource而不是StaticResource。 StaticResource仅评估一次，而DynamicResource实际上会监听更改。

Answer 2

你应该：

使用加载资源字典您已定义的XamlReader 新风格
从加载的资源中获取对新样式的引用（newStyle =（Style）resource [“styleName]）
在控件上设置新样式：control.Style = newStyle

HTH

再见

Answer 3

您可以使用ContentControl - 此处它会根据ViewType变量更改xaml。

<ContentControl Style="{StaticResource ScriptsViewTemplate}" VerticalAlignment="Stretch" />   


<Style x:Key="ScriptsViewTemplate" TargetType="ContentControl">
<Style.Triggers>
  <DataTrigger Binding="{Binding Path = ViewType,Mode=TwoWay}" Value="True">
    <Setter Property="Template" Value="{StaticResource ScriptsTreeViewTemplate}"/>
  </DataTrigger>
  <DataTrigger Binding="{Binding Path = ViewType,Mode=TwoWay}" Value="False">
    <Setter Property="Template" Value="{StaticResource ScriptsListViewTemplate}"/>
  </DataTrigger>
</Style.Triggers>
</Style>

Answer 4

Use resource dictionaries

..和switch them at runtime：）

祝你好运

（哦，对不起我的懒惰：P）

如何使WPF资源样式在运行时可切换？
