我有一个网格视图
<asp:BoundField DataField="UnusedTicketAmount" HeaderText="UnusedTicketAmount" />
<asp:BoundField DataField="ddlUnusedAmount" HeaderText="ddlUnusedAmount" />
<asp:BoundField DataField="AirlinePenality" HeaderText="AirlinePenality" />
<asp:BoundField DataField="ddlAirlinePenality" HeaderText="ddlAirlinePenality" />
<asp:BoundField DataField="NetRefundProcess" HeaderText="NetRefundProcess" />
<asp:BoundField DataField="ddlNetRefundProcess" HeaderText="ddlNetRefundProcess" />
<asp:BoundField DataField="RefundableCommission" HeaderText="RefundableCommission" />
<asp:BoundField DataField="ddlRefundableCommission" HeaderText="ddlRefundableCommission" />
<asp:BoundField DataField="CouponRefunded" HeaderText="CouponRefunded" />
<asp:BoundField DataField="RefundType" HeaderText="RefundType" />
在这个gridview中,我想将airlinepenality和ddlairlinepanelity添加到一列中,我该如何做到这一点提前谢谢
