There is no native multiselect combobox in WPF. Please check my blog for a simple hack using expression blend to achieve a multi selection on combobox. http://jobijoy.blogspot.com/2009/02/simple-multiselect-combobox-using.htmlThe idea is to utilize the Multi-Selection feature of ListBox in to ComboBox by editing the control template.
WPF 中没有本机多选组合框。请查看我的博客，了解使用表达式混合在组合框上实现多选的简单技巧。 http://jobijoy.blogspot.com/2009/02/simple-multiselect-combobox-using.html这个想法是通过编辑控件模板将ListBox 的Multi-Selection 特性利用到ComboBox 中。
But for accessing the selected items you might need to use the bellow line in the code.
但是要访问所选项目，您可能需要使用代码中的波纹管。
((ListBox)cmbBox.Template.FindName("lstBox",cmbBox)).SelectedItems
Where cmbBoxis your combobox and lstBoxis the ListBox inside the controltemaplate.
其中cmbBox是您的组合框，lstBox是控件模板内的列表框。

I'm not sure how a ComboBoxwould display data in this fashion, as it is designed as a single-selection Control.
我不确定 aComboBox将如何以这种方式显示数据，因为它被设计为单选控件。
Maybe you are looking for something like a ListBoxor ListViewwith a SelectionModeof Multipleor Extended?
也许你正在寻找的东西像ListBox或ListView用SelectionMode的Multiple还是Extended？
<ListBox SelectionMode="Multiple" />
<ListBox SelectionMode="Extended" />

I used an expander and filled the expander's header with the selection and the content with a list box. The list box is binded to a collection. Whenever user make a selection, I update the header to show what user has selected.
我使用了一个扩展器，并用选择和一个列表框的内容填充了扩展器的标题。列表框绑定到一个集合。每当用户进行选择时，我都会更新标题以显示用户选择的内容。
