如何获取右键单击打开上下文菜单之前的ListView项

Question

I have a ListView with a ContextMenu attached to it. In the menu handler function I want to know, which item of the ListView was right clicked before the ContextMenu was shown.

How can I do that ?

I'm using WPF and C#

Answer 1

Add a handler to the ListView.ContextMenuOpening event:

MainWindow.xaml:

<Grid>
    <ListView x:Name="_myListView" />
</Grid>

MainWindow.xaml.cs code-behind:

this._myListView.ContextMenuOpening += this._myListView_ContextMenuOpening;

...

void _myListView_ContextMenuOpening(object sender, ContextMenuEventArgs e)
{
    object selectedItem = this._myListView.SelectedItem;
    // do something with selectedItem...
}

Answer 2

您可以向每个ListViewItem添加MouseRightButtonUp处理程序。
