向固定列中添加行号

向固定列中添加行号，比如Microsoft Excel，请使用OwnerDrawCell 时间来在固定列中画出数字并左对齐。

1.     添加下面的代码到Form_Load 事件中，触发OwnerDrawCell 事件：

•    Visual Basic

Me.C1FlexGrid1.DrawMode = C1.Win.C1FlexGrid.DrawModeEnum.OwnerDraw

     

•    C#

this.c1FlexGrid1.DrawMode = C1.Win.C1FlexGrid.DrawModeEnum.OwnerDraw;

 

2.     添加OwnerDrawCell 事件：

•    Visual Basic

Private Sub C1FlexGrid1_OwnerDrawCell(ByVal sender As Object, ByVal e

As C1.Win.C1FlexGrid.OwnerDrawCellEventArgs) Handles C1FlexGrid1.OwnerDrawCell

If e.Row >= Me.C1FlexGrid1.Rows.Fixed And e.Col = Me.C1FlexGrid1.Cols.Fixed - 1 Then

Dim rowNumber As Integer = e.Row - Me.C1FlexGrid1.Rows.Fixed + 1

e.Text = rowNumber.ToString()

End If

End Sub

 

•    C#

private void c1FlexGrid1_OwnerDrawCell(object sender,

C1.Win.C1FlexGrid.OwnerDrawCellEventArgs e)

{

if ((e.Row >= this.c1FlexGrid1.Rows.Fixed) & (e.Col ==

(this.c1FlexGrid1.Cols.Fixed - 1)))

{

e.Text = ((e.Row - this.c1FlexGrid1.Rows.Fixed) + 1).ToString();

}

}

本主题演示如下：

行号出现在第一列，它是固定的并左对齐，就像Microsoft Excel一样。
