Or..

private void appList_MouseDoubleClick(object sender, RoutedEventArgs e) {
ListViewItem app = (ListViewItem)appList.Items[appList.SelectedIndex];
MessageBox.Show("you selected: " + app.Content);
}

I'm assuming you mean to use a binding to TheSelectedItem, but anyway that wouldn't work in my particular case for at least two reasons:

1. I'm using a multi-selected ListView (SelectionMode of Multiple), so SelectedItem is meaningless.

2. I only want to act in response to mouse double-clicks, not selection.

Responding to a selection is easy, but it isn't what I'm trying to do. In any case, if you want take action on a selection change, a better way to do that is to use the SelectionChanged event.

That's overly complex.Why would you do that?If you...

That's overly complex.

Why would you do that?

If you have a listview, just do

<ListView SelectedItem="TheSelectedItem" ... >

and in the setter for TheSelectedItem do what you want with it.

Using

MyDataItemType item = (MyDataItemType)((ListViewItem)dep).DataContext

instead of

MyDataItemType item = (MyDataItemType)MyListView.ItemContainerGenerator.ItemFromContainer(dep);

is a bit more straight forward but may only work, if data source binding is used for the list view.

2008-07-16T11:07:33.025-07:00

As the last comment indicated, you need to handle ContentElement's differently. If you hit a content element then you should get the logical parent.

2008-07-02T06:02:54.581-07:00

This code fails if the OriginalSource is derived from FrameworkContentElemnt (e.g. anything in a FlowDocument, such as Document.Run). Unfortunately, VisualTreeHelper deals with Visual and FrameworkElement objects, but not FrameworkContentElement objects. 8-|

Thanks for the info. It worked great in my project and helped me solve two issues I was having. I really am starting to like WPF, but it is still taking a long time to figure it all out.

Thanks much, you just saved me some time figuring it out. Here is a VB version.
Dim clickedToDoItem As ToDoItemInfo
Dim dep As DependencyObject = CType(e.OriginalSource, DependencyObject)
Do While dep IsNot Nothing AndAlso Not TypeOf (dep) Is ListViewItem
dep = VisualTreeHelper.GetParent(dep)
Loop
If dep Is Nothing Then
Return
Else
clickedToDoItem = CType(Me.lvToDo.ItemContainerGenerator.ItemFromContainer(dep), ToDoItemInfo)
End If
MessageBox.Show(String.Format("You clicked item: date={0},description={1}", clickedToDoItem.Due, clickedToDoItem.Description))

I saw how to get row or item, but how can I get column information from the mouse click position?
