Datagridview coloring cell

I'm experiencing a problem with the datagridview. I'm trying to create a program that allows me to run certain tests. I want to list them in a datagridview. Then with a counter I want the program to go through the active serverprocesses and run them. In the overview I want to visualize whether a process is active by coloring a cell that i add. I've done this before and used the same code but this time it doesn't seem to work. You can find my code for the load event of the form here. Can anyone tell me what I'm doing wrong?

 Private Sub frmServerProcesses_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Dim strSQL As String
    Dim oDR As SqlClient.SqlDataReader = Nothing

    'bij het opstarten moet de stopknop disabled zijn
    btnServerStop.Enabled = False
    btnServerStart.Enabled = True

    statServerProcesseslbl.Text = "Server ready"

    'opvragen van de processen
    strSQL = " SELECT * FROM SERVERPROCESSES"

    Dim connection As New SqlConnection(SQLConnectstring)
    Dim dataadapter As New SqlDataAdapter(strSQL, connection)
    Dim ds As New DataSet()
    connection.Open()
    dataadapter.Fill(ds, "SERVERPROCESSES")
    connection.Close()

    dgvServerProcesses.DataSource = ds
    dgvServerProcesses.DataMember = "SERVERPROCESSES"
    dgvServerProcesses.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells
    dgvServerProcesses.Columns("LASTRUNDATE").AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill
    'lege row die normaal wordt toegevoegd verwijderen
    dgvServerProcesses.AllowUserToAddRows = False

    'extra kolom toevoegen voor kleuren van actief of niet
    dgvServerProcesses.Columns.Add("TEST", "TEST")

    For i As Integer = 1 To dgvServerProcesses.Rows.Count - 1
        If dgvServerProcesses.Rows(i).Cells(2).Value = "True" Then

            dgvServerProcesses.Rows(i).Cells(2).Style.BackColor = Color.Black
        End If
    Next

    'lege row die normaal wordt toegevoegd verwijderen
    dgvServerProcesses.AllowUserToAddRows = False

End Sub

I've just tried to put both things in separate subs. So filling up the grid and marking the active ones are separate now. Both subs are called by the load sub. But still the colors don't work. But if I call the checkprocess with a button it does work. But what is also very strange is that the columncount is different. If I call it with a button he starts counting on 1 in the other case on 0. Can someone explain that to me? My new code to check the active boolean is shown here

Public Sub CheckProcessActive()
    For i As Integer = 0 To dgvServerProcesses.Rows.Count - 1
        If dgvServerProcesses.Rows(i).Cells(2).Value = "True" Then
            dgvServerProcesses.Rows(i).Cells("ACTIVE").Style.BackColor = Color.Green
        Else
            dgvServerProcesses.Rows(i).Cells("ACTIVE").Style.BackColor = Color.Red
        End If
    Next
End Sub
