Get the item doubleclick event of listview.

Question

How to get the item double click event of listview?

Answer 1

In the ListBox DoubleClick event get the selecteditem(s) member of the listbox, and there you are.

void ListBox1DoubleClick(object sender, EventArgs e)
 {
  MessageBox.Show(string.Format("SelectedItem:\n{0}",listBox1.SelectedItem.ToString()));
 }

Answer 2

Either use the MouseDoubleClick event, and also, all the MouseClick events have a click count in the eventargs variable 'e'. So if e.ClickCount == 2, then doubleclicked.

Answer 3

I'm using something like this to only trigger on ListViewItem double-click and not for example when you double-click on the header of the ListView.

private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DependencyObject obj = (DependencyObject)e.OriginalSource;

    while (obj != null && obj != myListView)
    {
        if (obj.GetType() == typeof(ListViewItem))
        {
            // Do something here
            MessageBox.Show("A ListViewItem was double clicked!");

            break;
        }
        obj = VisualTreeHelper.GetParent(obj);
    }
}

Answer 4

It's annoying, but the best way to do it is something like:

<DataTemplate Name="MyCoolDataTemplate">
    <Grid Loaded="HookLVIClicked" Tag="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}">
        <!-- your code here -->
    </Grid>
</DataTemplate>

Then in the code:

public void HookLVIClicked(object sender, RoutedEventArgs e) {
    var fe = (FrameworkElement)sender;
    var lvi = (ListViewItem)fe.Tag;
    lvi.MouseDoubleClick += MyMouseDoubleClickHandler;
}

Answer 5

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <EventSetter Event="MouseDoubleClick" Handler="listViewItem_MouseDoubleClick" />
    </Style>
</ListView.ItemContainerStyle>

The only difficulty then is if you are interested in the underlying object the listviewitem maps to e.g.

private void listViewItem_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    ListViewItem item = sender as ListViewItem;
    object obj = item.Content;
}

I needed that as well. I found that on msdn:

I think this delegate is for that.
