单击内部的按钮时，使列表框处于选中状态 [英] make listbox selected when click button inside

问题描述

我有一个列表框，它的项目包含button，textbllock.我已成功将按钮的命令绑定到Viewmodel，并在该listboxitem中单击button时获得了listboxitem的索引.现在的问题是，当我单击listboxitem内的按钮时，没有选择listboxitem.

仅当我单击按钮框和文本块外部的listboxitem区域时，才选择listboxitem.

当我单击列表框项目中的按钮时，如何使列表框项目处于选中状态?

listboxitem is selected only when I click the area of listboxitem outside button and textblock.

how can I make listboxitem selected when I click button inside this listboxitem ? is there any simple solution to do that?

推荐答案

您可以在视图模型中将列表框的SelectedValue绑定到属性.
当您选择按钮时，您将提交带有列表框项目有效负载的委托命令.然后可以将此项目放置到绑定的selectedvalue的viewmodel属性中.

you could, in your viewmodel bind the SelectedValue of the listbox to a property.

When you select the button you would file a delegate command with a payload of the listbox item. This item can then be placed into the viewmodel property for the bound selectedvalue.
