GridView欄位的跨欄顯示寫法

方式有很多種，我是在GridView的RowDataBound事件處理，處理方式如下範例：

 Private Sub 欄位處理(ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)

        e.Row.Cells.Clear()

        Dim headROW As GridViewRow = New GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal)
        Dim head2Cell As TableCell

        head2Cell = New TableCell()
        With head2Cell
            .Text = "分配方式"
            .HorizontalAlign = HorizontalAlign.Center
            .ColumnSpan = 2    
        End With
        headROW.Cells.Add(head2Cell)

        head2Cell = New TableCell
        With head2Cell
            .Text = "職務名稱"
            .HorizontalAlign = HorizontalAlign.Center
        End With
        headROW.Cells.Add(head2Cell)

        gv.Controls(0).Controls.Add(headROW)

    End Sub

    Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound

        If e.Row.RowType = DataControlRowType.Header Then
            '總共有三個欄位，將第一個和第二個Spain起來
            欄位處理(e)
        End If  

    End Sub
