在Avalonia中不需要 DataTemplateSelector
,因为您可以自己实现 IDataTemplate
并在其中选择模板
In Avalonia DataTemplateSelector
isn't needed because you can just implement IDataTemplate
yourself and select the template there.
i.e.
public class MyTemplateSelector : IDataTemplate
{
public bool SupportsRecycling => false;
[Content]
public Dictionary<string, IDataTemplate> Templates {get;} = new Dictionary<string, IDataTemplate>();
public IControl Build(object data)
{
return Templates[((MyModel) data).Value].Build(data);
}
public bool Match(object data)
{
return data is MyModel;
}
}
public class MyModel
{
public string Value { get; set; }
}
<ItemsControl>
<ItemsControl.Items>
<scg:List x:TypeArguments="local:MyModel">
<local:MyModel Value="MyKey"/>
<local:MyModel Value="MyKey2"/>
</scg:List>
</ItemsControl.Items>
<ItemsControl.DataTemplates>
<local:MyTemplateSelector>
<DataTemplate x:Key="MyKey">
<TextBlock Background="Red" Text="{Binding Value}"/>
</DataTemplate>
<DataTemplate x:Key="MyKey2">
<TextBlock Background="Blue" Text="{Binding Value}"/>
</DataTemplate>
</local:MyTemplateSelector>
</ItemsControl.DataTemplates>
</ItemsControl>
