如何在VB.Net中删除加载时的空白DataGridView行

Question

我有一个DataGridView，它受VB.net Windows窗体应用程序中的数据源绑定。当我将数据导入DataGrid时，我希望任何空白或空字段都用红色着色，直到用户输入数据。我已经完成了这个，但我有一个小问题。当用户向DataGrid添加一个新的空行并且没有填充任何数据时，加载时新形成的行将完全用红色着色，而我想在加载时删除这个新生成的行。这就是我这样做的方式，但我没有成功。非常感谢您提供的任何帮助或建议。

 Private Sub DataGridView1_CellFormatting(sender As Object, e As DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    'Created a Boolean flag if empty
    Dim empty as Boolean = True

    Dim cellString = DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value

    If cellString Is Nothing OrElse IsDBNull(cellString) OrElse cellString.ToString = String.Empty OrElse String.IsNullOrWhiteSpace(cellString) = True Then
       empty = True
    Else
       empty = False
    End If
    'End If

    'create variable assigned the rowindex of the last row of the DataGridView
    Dim lastRow As String = DataGridView1.Rows(DataGridView1.RowCount - 1).Cells(0).Value        
    If (e.ColumnIndex = 0 OrElse e.ColumnIndex = 1 OrElse e.ColumnIndex = 2) Then
       If empty = False Then
           'If row is not empty then allow the newly generated row on load
           DataGridView1.AllowUserToAddRows = true
       Else               
           If empty = True AndAlso e.RowIndex = lastRow Then
              'If row is empty and it’s the last row then prevent the row from being added to ‘the datagridview                            
              DataGridView1.AllowUserToAddRows = False               
           Else If empty = True AndAlso e.RowIndex <> lastRow Then
              'the row is empty and not the last row then paint the cell red
              DataGridView1.Item(e.ColumnIndex, e.RowIndex).Style.BackColor = Color.Red
           End If
        End If
     End If 
 End Sub
