C# DevExpress TreeListControl创建自定义单元格模板

我在用电脑装订东西时遇到了麻烦

我想创建一个自定义单元格模板，而不是默认的。使用默认单元格模板时，我的绑定工作正常。以下是我的项目：

为什么我的（

）没有显示员工的姓名？我该怎么做才能把它绑定到那个财产上？如果我删除了CellTemplate，它可以工作，但我想拥有我的自定义样式…

好的，我将在Devex团队之前回答：）

更改此项：

<TextBlock Text="{Binding Path=Name}" Foreground="Blue" />

为此：

<TextBlock Text="{Binding Path=Data.Name}" Foreground="Blue" />

或者简单地说：

<TextBlock Text="{Binding Data.Name}" Foreground="Blue" />

非常确定您想要的是Path=Row。Name@Aron不。在发布之前，我已经测试了我的答案。100%肯定。效果很好，你的回答速度比Devex团队快得多！以下是devExpress的问题：@TonoNam我不能责怪他们，他们每天都要处理100个问题。另外，他们现在可能已经下班了。在我看来，可以使用TreeListColumn的FieldName，而不是对每一列使用重写的CellTemplates
