aspxgridview 增加行号

近日，是项目中要用到 DEVEXPRESS的ASPxGridView控件，要求能自动显示行号，现将代码共享一下。

aspx页面：===========================================

 <dx:ASPxGridView ID="ASPxGridView1" runat="server" AutoGenerateColumns="False" KeyFieldName="Id"  Width="100%"
    oncustomunboundcolumndata="ASPxGridView1_CustomUnboundColumnData"
                            ClientIDMode="AutoID">
                            <Columns>
                                <dx:GridViewDataTextColumn Caption="序号" FieldName="hh" UnboundType="Integer">
                                </dx:GridViewDataTextColumn>
                                <dx:GridViewDataColumn Caption="工作类型" FieldName="TaskType">
                                <DataItemTemplate>
                                <%#GetProjectNodeName((int)Eval("TaskType"))%>
                                </DataItemTemplate>                      
                                </dx:GridViewDataColumn>

</Columns>
                        </dx:ASPxGridView>

cs代码部分：=========================================

        /// <summary>
        /// 显示行号
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        protected void ASPxGridView1_CustomUnboundColumnData(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewColumnDataEventArgs e)
        {
            if (e.Column.Caption == "序号" && e.IsGetData)
                e.Value = (e.ListSourceRowIndex + 1).ToString();
        }
