我要赶在列表视图是从左点击空白处事件 - 即点击ListView控件内没有项目

I want to catch the event when a listview is left-clicked on an empty space - i.e. clicking on no item within the listview control.

推荐答案

如果您将一个处理器上会被点击一个ListViewItem的以外的地区时，只有火在ListView MouseLeftButtonDown事件。项目内的任何点击将通过项目本身进行处理来驱动ListView的选择行为。

If you attach a handler to the MouseLeftButtonDown event on the ListView it will only fire when areas outside of a ListViewItem are clicked. Any clicks inside the items will be handled by the items themselves to drive the ListView's selection behavior.

您可以通过调整背景（无法点击，别的是空{X}）进行更改可点击区域。还要确保你没有使用上ListView控件本身就是一个空的背景（白色是默认的，透明的作品太）。

You can make changes to the clickable areas by adjusting the Background ({x:Null} is not clickable, anything else is) and Margin of the ListViewItems by setting an ItemContainerStyle on the ListView. Also make sure that you are not using a null Background on the ListView itself (White is the default, Transparent works too).
