Dim oCtl As Control
Dim iX As Integer

For Each oCtl In GroupBox3.Controls
If TypeName(oCtl) = "CheckBox" And oCtl.Enabled = True Then iX = iX + 1

If iX > 0 Then
CheckBox1.Checked = True

ElseIf CheckBox19.Checked = False And CheckBox20.Checked = False And CheckBox21.Checked = False And CheckBox22.Checked = False And CheckBox23.Checked = False Then

CheckBox1.Checked = False
Exit For
End If
End Sub

Here, Checkbox1 to Checkbox5 is the assumed named of the Checkboxes inside Purchase Requisition group box.

chkPurchaseRequisition is also the Checkbox for your Purchase Requistion checkbox

Try this one:

 Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
CheckBox1.CheckedChanged, CheckBox2.CheckedChanged, CheckBox3.CheckedChanged, CheckBox4.CheckedChanged, CheckBox5.CheckedChanged
    If sender.Checked = True Then
        chkPurchaseRequisition.Checked = True
        Dim AllUnchecked As Boolean = True
        For Each c As Control In grpboxPurchaseRequisition.Controls.OfType(Of CheckBox)()
            If DirectCast(c, CheckBox).Checked = True Then
                AllUnchecked = False
                Exit For
            End If
        If AllUnchecked = True Then
            chkPurchaseRequisition.Checked = False
        End If
    End If

End Sub
