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

    private void positionsListView_DoubleClick(object sender, EventArgs e)
    {
        if (positionsListView.SelectedItems.Count == 1)
        {
            ListView.SelectedListViewItemCollection items = positionsListView.SelectedItems;

            ListViewItem lvItem = items[0];
            string what = lvItem.Text;

        }
    }

Answer 2

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

http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.activation.aspx

I think this delegate is for that.

Answer 3

The sender is of type ListView not ListViewItem.

    private void listViewTriggers_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        ListView triggerView = sender as ListView;
        if (triggerView != null)
        {
            btnEditTrigger_Click(null, null);
        }
    }

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 5

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 6

Use the ListView.HitTest method

    private void listView_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        var senderList  = (ListView) sender;
        var clickedItem = senderList.HitTest(e.Location).Item;
        if (clickedItem != null)
        {
            //do something
        }            
    }

Or the old way

    private void listView_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        var senderList  = (ListView) sender;                        
        if (senderList.SelectedItems.Count == 1 && IsInBound(e.Location, senderList.SelectedItems[0].Bounds))
        {
            //Do something
        }
    }

    public  bool IsInBound(Point location, Rectangle bound)
    {
        return (bound.Y <= location.Y && 
                bound.Y + bound.Height >= location.Y &&
                bound.X <= location.X && 
                bound.X + bound.Width >= location.X);
    }
