If you are using the data binding, then get the values from the source object.

Or try this:

Dim values As Object() = DataGridView1.Rows(0).Cells.Cast(Of DataGridViewCell).Select(Function(c) c.Value).ToArray

This example gets the first row. Use another index or adjust it for your needs.

Thank you Viorel that done it for me.

Dim values As Object() = PersonDataGridView.Rows(PersonDataGridView.CurrentRow.Index).Cells.Cast(Of DataGridViewCell).Select(Function(c) c.Value).ToArray
        Dim msg As String = String.Empty
        For i = 0 To values.Count - 1
            msg &= vbCrLf & values.GetValue(i).ToString
        Next
        MsgBox(msg)

How would I do the same thing for column values. I've tried altering the code but can not solve it.

I found some code and edited to the follow, however your code for the rows in neater.

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Dim array As String() = New String(PersonDataGridView.Rows.Count - 1) {}
        Dim msg As String = String.Empty

        Dim j As Integer = PersonDataGridView.CurrentCell.ColumnIndex
        For i As Integer = 0 To PersonDataGridView.Rows.Count - 1
            array(i) = PersonDataGridView.Rows(i).Cells(j).Value
            msg &= array(i) & vbCrLf
        Next
        MsgBox(msg)
    End Sub

In case of columns, for example:

Dim column_index = 0
Dim values As Object() = PersonDataGridView.Rows.Cast(Of DataGridViewRow).Select(Function(r) r.Cells(column_index).Value).ToArray

or

Dim msg As String = String.Join(vbCrLf, PersonDataGridView.Rows.Cast(Of DataGridViewRow).Select(Function(r) r.Cells(column_index).Value))

 'Current Column Values
    Private Sub btnCurrentColumnValues_Click(sender As Object, e As EventArgs) Handles btnCurrentColumnValues.Click
        Dim column_index As Integer = PersonDataGridView.CurrentCell.ColumnIndex
        Dim msg As String = String.Join(vbCrLf, PersonDataGridView.Rows.Cast(Of DataGridViewRow).Select(Function(r) r.Cells(column_index).Value))
        MsgBox(msg, vbOKOnly, "Column Values")
    End Sub
    'Current Column Values (2)
    Private Sub CurrentColumsValue2_Click(sender As Object, e As EventArgs) Handles CurrentColumsValue2.Click
        Dim column_index As Integer = PersonDataGridView.CurrentCell.ColumnIndex
        Dim values As Object() = PersonDataGridView.Rows.Cast(Of DataGridViewRow).Select(Function(r) r.Cells(column_index).Value).ToArray
        Dim msg As String = String.Empty
        For i = 0 To values.Count - 1
            msg &= values.GetValue(i).ToString & vbCrLf
        Next
