Hi all,

I'm populating a listview based on selected records in a datagridview. I want to sort the listview items (ascending) but somehow I keep getting 1,10,4,5 instead of 1,4,5,10. I am using CInt to convert the items to integer but this doesn't help.

Can anyone point me in the right direction?
Many thanks,
Eric

VB

Dim selectedRowCount As Integer = frmData.DataGridView1.Rows.GetRowCount(DataGridViewElementStates.Selected)

        If selectedRowCount > 0 Then
            Dim i As Integer
            For i = 0 To selectedRowCount - 1
                ListView1.Items.Add(CInt(frmData.DataGridView1.SelectedRows(i).Cells(0).Value))
            Next i

            ListView1.Sorting = SortOrder.Ascending
        End If

If u want something different then the default order routine.
U can implement an own sorting routine by implementing IComparer which u next supply to the list (u can pass it as an extra parameter in the Sort routine).

If u get the listviewitem in a local array, then remove them from the listview, the sort them your way in a list, then readd them to the listview, well then it' sorted your way. U need to disable sorting on the listview for this.

Solution 1

See here[^]; the default is alphabetical order, so 10 comes before 4.
