Get the item doubleclick event of listview

Question

What do I need to do in order to reference the double click event for a listview control?

Answer 1

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);
    }
}

You can get the ListView first, and then get the Selected ListViewItem. I have an example for ListBox, but ListView should be similar.

private void listBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        ListBox box = sender as ListBox;
        if (box == null) {
            return;
        }
        MyInfo info = box.SelectedItem as MyInfo;
        if (info == null)
            return;
        /* your code here */
        }
        e.Handled = true;
    }

Answer 3

<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 found this on Microsoft Dev Center. It works correctly and ignores double-clicking in wrong places. As you see, the point is that an item gets selected before double-click event is triggered.

private void listView1_DoubleClick(object sender, EventArgs e)
{
    // user clicked an item of listview control
    if (listView1.SelectedItems.Count == 1)
    {
        //do what you need to do here            
    }
}

I don't yet have a large enough reputation score to add a comment where it would be most helpful, but this is in relation to those asking about a .Net 4.5 solution.

You can use the mouse X and Y co-ordinates and the ListView method GetItemAt to find the item which has been clicked on.

private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    ListViewItem item = myListView.GetItemAt(e.X, e.Y)
    // Do something here
}

for me, I do double click of ListView in this code section .

    this.listView.Activation = ItemActivation.TwoClick;

    this.listView.ItemActivate += ListView1_ItemActivate;

ItemActivate specify how user activate with items

When user do double click, ListView1_ItemActivate will be trigger. Property of ListView ItemActivate refers to access the collection of items selected.

    private void ListView1_ItemActivate(Object sender, EventArgs e)
    {

        foreach (ListViewItem item in listView.SelectedItems)
           //do something

    }

it works for me.
