Viewmodel中的Combobox selectionchange事件 [英] Combobox selectionchange event in Viewmodel

问题描述

我是WPF的新手。我想在Viewmodel类中实现ComboBox的selectionChange事件，其中组合框在Xaml中。



我不需要选择更改事件在xaml.cs



请建议更好的方法。

解决方案

Prasant，为此您必须使用 ICommand viewmodel 中的属性。并将此属性绑定到XAML中的 SelectionChanged 事件。

*您还可以使用交互式触发器 - < br $>

解决方案

Prasant, for this you have to use ICommand Property inside your viewmodel. And bind this property to your SelectionChanged event in XAML.
