[RESOLVED] Sort Listview by checkbox state

Does anybody know how to sort a Listview by checkbox state, so all checked items are at the top of the list.

I'm targeting Framework 2.0.

Sorting a ListView is the same regardless. In all the examples you will have already found by searching the web, you will have seen that you need to create an object that implements IComparer to compare two ListViewItems. You can compare them any way you want, including by their Checked properties.

Thanks. I didn't know I could use it to compare the Checked property as well.

vb.net Code:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    ListView.ListViewItemSorter = New ListViewCompareChecked(SortOrder.Descending)
    ListView.Sort()
End Sub
 
Public Class ListViewCompareChecked
    Implements IComparer
 
    Private m_SortOrder As SortOrder
 
    Public Sub New(ByVal sort_order As SortOrder)
        m_SortOrder = sort_order
    End Sub
 
    Public Function Compare(ByVal x As Object, ByVal y As Object) _
     As Integer Implements System.Collections.IComparer.Compare
 
        Dim item_x As ListViewItem = DirectCast(x, ListViewItem)
        Dim item_y As ListViewItem = DirectCast(y, ListViewItem)
 
        If m_SortOrder = SortOrder.Ascending Then
            Return item_x.Checked.CompareTo(item_y.Checked)
        Else
            Return -item_x.Checked.CompareTo(item_y.Checked)
        End If
    End Function
End Class
