Use For Each Loop Instead of For Loop
See below modified code :

VB

For Each _mRow As DataRow In DataSetName.Tables(0).Rows
     Dim ls As New ListViewItem
     ls.Text = DataSetName.Tables(0).Rows(ct).Item(0)
     If ls.SubItems.Add(_mRow.Item(2)) <= ls.SubItems.Add(_mRow.Item(2)) Then
           ls.BackColor = Color.Yellow
           lvpoapproveitem.Items.Add(ls)
     End If
Next

Also check 3rd column exist or not in your DataSet Table because you are referring Index (2)

VB

.Tables(0).Rows(ct).Item(2)

I hope this will help you. :)

Perhaps, what you meant to do was have the Next at the bottom of the code, rather than at the top...
That way, ct would change for each row, rather than just being set to the number of rows before you actually use it?

VB

Dim ct As Integer
For ct = 0 To .Tables(0).Rows.Count - 1
    Dim ls As New ListViewItem
    ls.Text = .Tables(0).Rows(ct).Item(0)
    If ls.SubItems.Add(.Tables(0).Rows(ct).Item(2)) <= ls.SubItems.Add(.Tables(0).Rows(ct).Item(2)) Then
        ls.BackColor = Color.Yellow
        lvpoapproveitem.Items.Add(ls)

    End If
Next
