Datagridview doesnt show data in rows - vb.net

Question

I am currently working on project in which i have to display IP Configuration to user in VB.Net Application.
I am using DataGridView to display IP Config to user.
But problem is Datagridview doesnt display anything in its row at all.
Image for proof
Here is the code
Public Sub MT_Validate_Msg(ByRef lbData() As Byte)
Dim lsAddr(3) As String
Dim lsMAC(5) As String
Dim lstConfig As TCP_SER_Config
If lbData.Length >= 256 Then
'Check Header Footer and Response Size
If lbData(0) = Asc("$") And lbData(1) = Asc("#") _
And lbData(254) = Asc("<") And lbData(255) = Asc(">") _
And lbData(2) = UDP_RESPONSE_SIZE And lbData(3) = 0 Then
gnDevice_Search_Count += 1
'MsgBox("Response Received")
lsAddr(0) = lbData(7).ToString
lsAddr(1) = lbData(9).ToString
lsAddr(2) = lbData(11).ToString
lsAddr(3) = lbData(13).ToString
lstConfig.IP = String.Join(".", lsAddr)
lsAddr(0) = lbData(15).ToString
lsAddr(1) = lbData(17).ToString
lsAddr(2) = lbData(19).ToString
lsAddr(3) = lbData(21).ToString
lstConfig.Subnet = String.Join(".", lsAddr)
lsAddr(0) = lbData(23).ToString
lsAddr(1) = lbData(25).ToString
lsAddr(2) = lbData(27).ToString
lsAddr(3) = lbData(29).ToString
lstConfig.Gateway = String.Join(".", lsAddr)
lstConfig.Alive_Time = lbData(31)
lsMAC(0) = Hex(lbData(33)).ToString
lsMAC(1) = Hex(lbData(34)).ToString
lsMAC(2) = Hex(lbData(35)).ToString
lsMAC(3) = Hex(lbData(36)).ToString
lsMAC(4) = Hex(lbData(37)).ToString
lsMAC(5) = Hex(lbData(38)).ToString
lstConfig.MAC = String.Join("-", lsMAC)
MT_FillGrid(lstConfig)
End If
End If
End Sub
Public Sub MT_FillGrid(ByRef lstTCPConfig As TCP_SER_Config)
Dim row As String() = New String() {gnDevice_Search_Count.ToString, lstTCPConfig.IP, lstTCPConfig.Subnet, _
lstTCPConfig.Gateway, lstTCPConfig.Alive_Time.ToString, lstTCPConfig.MAC}
GridDev_List.Rows.Add(row)
row = New String() {"1", "192.168.0.100", "255.255.255.0", "255.255.255.255", "60", "22-0B-3C-2D-00-01"}
GridDev_List.Rows.Add(row)
End Sub
Expecting a result like this, Where i am going wrong in code ?
