添加子组件到组合框 [英] add subitems to combobox

问题描述

先生，



我在组合框，电影和新闻中有两个类别。



怎么做当我选择电影成为movie1和movie2子类别时，我添加了子类别。

Sir,

I have two categories in combobox, Movies and News.

How do I add sub-categories when I select movies to become movie1 and movie2 sub-categories.

推荐答案

我认为你真正想要的是 TreeView 。 ComboBox 不是显示可选子项的适当控件。

I think what you really want is a TreeView. A ComboBox is not the appropriate control to display selectable sub-items.

一个非优雅的启动解决方案，就是创建一个内部组合框，作为一个组合框的组合。您可以设置它们的样式以改善其外观，仍然是一个树形视图，如已经说过的那样，必须具备wpf / xaml开发技能

A non-elegant solution for starting, is to create an inner combobox, as a comboitem of an outter combobox. You can style them to improve the look of it, still, a treeview as was already said is the way to go and a must have skill with wpf/xaml development
