在 WinForms 中更改 DataGridView 特定单元格的样式

Question

我在我的 Windows 应用程序中将 DataGridView 与 DataTable 绑定。在 DataGridView 的 RowsAdded 事件中，我正在编写代码以更改特定单元格的样式。

我已经尝试了以下代码，但它不起作用

Private Sub grdView_RowsAdded(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowsAddedEventArgs) Handles grdView.RowsAdded

        Dim f = New Font("Times New Roman", 10, FontStyle.Bold)
        For index As Integer = e.RowIndex To e.RowIndex + e.RowCount - 1
            Dim row As DataGridViewRow = grdView.Rows(index)
            If Decimal.Parse(row.Cells("Variance Up").Value.ToString) >= Decimal.Parse(txtRise1.Text) Then
                row.Cells("Variance Up").Style.ForeColor = Color.Red
                row.Cells("Variance Up").Style.Font = f
            ElseIf Decimal.Parse(row.Cells("Variance Up").Value.ToString) >= Decimal.Parse(txtRise2.Text) Then
                row.Cells("Variance Up").Style.ForeColor = Color.Red
                row.Cells("Variance Up").Style.Font = f
            End If
        Next
    End Sub

我想做的如下：

这个问题已经在 cmets 中得到解答：

@FarhanMukadam that's partly why RowsAdded is not suitable. Of course when you bind your grid, it will add rows for you (instead of doing manually) and the RowsAdded will be fired. – King King

@KingKing So whats the solution? Which event should i use? – Farhan Mukadam

@FarhanMukadam maybe RowPosPaint or CellValueChanged – King King

@KingKing RowPostPaint works. Thank You. – Farhan Mukadam
