AspxGridView自定义列CustomColumnDisplayText事件与GridView中的rowdatabound事件一样

 protected void ASPxGridView1_CustomColumnDisplayText(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewColumnDisplayTextEventArgs e)
    {
        if (e.Column.VisibleIndex == 8)
        {
            string users= e.GetFieldValue ("account").ToString();
            string str_right = "select product_right from tbl_admin where account='"+users +"'";
            SqlDataReader dr = co.storereadershop(str_right );
            if (dr.Read())
            {
                e.DisplayText = dr[0].ToString();
            }
            
        }

    }

AspxGridView中根据判断隐藏某个值的事件
OnCustomColumnDisplayText="Grid_CustomColumnDisplayText"
中放一列普通列
  <dxgw:GridViewDataTextColumn Caption="操作" VisibleIndex="7" Width="28px" HeaderStyle-HorizontalAlign="Center">                    
 </dxgw:GridViewDataTextColumn> 
----------------------------------------- 
方法
 protected void Grid_CustomColumnDisplayText(object sender, ASPxGridViewColumnDisplayTextEventArgs e)
    {
        if (e.Column.VisibleIndex == 7)
        {
//如果ItemType等于1显示超链接，不等于1不显示
            if (e.GetFieldValue("ItemType").ToString().Equals("1"))
            {
                e.DisplayText = "<a href=\"javascript:void(0);\" onclick=\"OnSetRuleClick(this,'" + e.GetFieldValue("ItemID") + "')\">设置规则</a>";
            }
            else
            {
                e.DisplayText = "";
            }
        }
    }

超链列
 <dxwgv:GridViewDataColumn Caption="标题" VisibleIndex="1" HeaderStyle-HorizontalAlign="Center"
                    Width="50%">
                    <Settings AllowSort="False" />
                    <EditFormSettings Visible="False"  />
                    <DataItemTemplate>
                        <a href="javascript:void(0);" onclick="OnMoreInfoClick(this,'<%# Container.KeyValue %>')">
                            <%#Eval("Title")%></a>
                    </DataItemTemplate>
                    <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                </dxwgv:GridViewDataColumn>
