Answer 1

您可以在 CellFormatting 活动中尝试...

Private Sub DataGridView1_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles DataGridView1.CellFormatting
    Dim sHeader As String = DataGridView1.Columns(e.ColumnIndex).Name

    If ucase(sHeader) = "QUARTER" Then '-------> change this with yours
        If e IsNot Nothing Then
            If e.Value IsNot Nothing Then
                Try
                    Select case e.Value
                        Case 1 : e.Value = "Q1"
                        Case 2 : e.Value = "Mid Year"
                        Case 3 : e.Value = "Q2"
                        Case 4 : e.Value = "End Year"
                    End Select
                    e.FormattingApplied = True
                Catch ex As FormatException
                    e.Value = ""
                End Try
            End If
        End If
    End If

End Sub

Answer 2

dataGridView.Rows[0].Cells[0].Value = desiredValue
dataGridView.Rows[1].Cells[0].Value = desiredValue
dataGridView.Rows[2].Cells[0].Value = desiredValue
dataGridView.Rows[3].Cells[0].Value = desiredValue

或者你可以遍历它们。您可以像这样访问gridView的数据的个人和平nameOfGridView.Rows[desiredRow].Cells[desiredColumn].Value

谢谢大家，但我能够使用它来获得它：

    protected string QuarterConvert(object strValue)
    {
        string retString = "";

        switch (Convert.ToString(strValue))
        {
            case "1":
                retString = "Q1";
                break;
            case "2":
                retString = "Mid-Year";
                break;
            case "3":
                retString = "Q3";
                break;
            case "4":
                retString = "Year-End";
                break;
            default:
                break;

        }
        return retString;
    }
