Private Sub GridWithLoop()

    Dim sum As Integer = 0
    Dim sum2 As Integer = 0
    Dim allrow As DataGridViewRow
    Dim band As DataGridViewBand

    For i As Integer = 0 To DataGridView2.Rows.Count() - 1 Step +1
        'sum = sum + DataGridView2.Rows(i).Cells(1).Value'
        allrow = DataGridView2.Rows(i)

        If allrow.Cells(1).Value.ToString = TextBox1.Text Then
            'Nothing happen'
        Else
            band = DataGridView2.Rows(i)
            band.Visible = False
        End If
    Next
End Sub

Does your DataGridView allow insertion of rows? You can not hide the line that is pending for new data entry. Test the allrow.IsNewRow property to avoid this. I do not understand why you are using the DataGridViewBand object for this purpose? Try this:

Private Sub GridWithLoop()

    Dim sum As Integer = 0
    Dim sum2 As Integer = 0
    Dim allrow As DataGridViewRow
    Dim band As DataGridViewBand

    For i As Integer = 0 To DataGridView2.Rows.Count() - 1 Step +1
        'sum = sum + DataGridView2.Rows(i).Cells(1).Value'
        allrow = DataGridView2.Rows(i)

        If allrow.Cells(1).Value.ToString = TextBox1.Text Then
            'Nothing happen'
        ElseIf Not allrow.IsNewRow Then
            allrow.Visible = False
        End If
    Next
End Sub
