[2005] Listview Group header click event?

[campster]

I have a listview that is displayed in details views. I want to be able to select all items in a group if the group header is clicked/double-clicked but I can't figure out how to deterimine that a heasder has been clicked. Any ideas?

BTW, I want the group header not the column header.

There is an example at http://msdn2.microsoft.com/en-us/lib...ps(vs.80).aspx which demonstrates something a bit different, but it does show how to deal with groups in events. Hope this might help.

Thanks Bullbog

I actually used that example to make a sortable listview and was trying to increase the functionality to include the header selection. I'll look into it a litle further if I get a chance.

I did it the lazy way: using a contextmenu. This allows me to select any item in the group or the group header.

Private Sub SelectGroupToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SelectGroupToolStripMenuItem.Click
        For Each item As ListViewItem In ListViewFiles.Items
            If item.Group.Header = ListViewFiles.FocusedItem.Group.Header Then
                item.Checked = True
            End If
        Next
    End Sub

I had to add this code to handle the case when more than one group exists.

Private Sub ListViewFiles_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListViewFiles.MouseDown
        Dim inc As Integer = 0
        Dim selection As ListViewItem = Nothing
 
        While selection Is Nothing
            selection = ListViewFiles.GetItemAt(e.X, e.Y + inc)
            inc += 1
        End While
        selection.Focused = True
    End Sub
