Wpf 如何在另一个DataTemplate中继承DataTemplate

wpf

Wpf 如何在另一个DataTemplate中继承DataTemplate,wpf,datatemplate,Wpf,Datatemplate,好吧，我不知道这是否可行，但是？我试图填充一个DataGrid（确切地说是Telerik RadGridView），并希望动态确定编辑控件。我试图创建一个网格来显示导入应用程序的数据，并显示三列（属性名、入站数据和当前数据库数据）。基于我的对象类中的属性，“属性名称”列需要在前面放置一个复选框。这与其他列一样，只要有条件地附加一个按钮，就可以进行查找（按钮前面会有一个文本框或文本块来显示当前值）。我希望这能解释我想做什么。下面是我提出的XAML 哦，这将进入WPF MVVM C应用程序谢谢你能

通常

ContentPresenters

会获得相应的隐式模板，因此您只需将其中一个的

内容

绑定到要模板化的属性或DataContext，并且应该对其进行模板化

（不确定这是否适用于您的问题，因为我不太明白您想说什么）

您可以将DataTemplate的DataType属性设置为不同viewmodels使用的不同类

如果同一viewmodel类必须根据内部值有条件地返回不同的模板，则可以在App.xaml中声明模板

<DataTemplate x:Key="AddCheckBox">
     ...
</DataTemplate>

希望这能有所帮助好的，我已经通过一些技巧解决了这个问题。我现在在CellEditTemplateSelector中动态创建DataTemplate。这允许我检查所有属性，并为适当的单元格添加控件和绑定

以下是基本的XAML网格：
