        protected void callbackPanel_Callback(object sender, DevExpress.Web.ASPxClasses.CallbackEventArgsBase e)

        {

            strGroupID = e.Parameter.ToString();

            DataBindInfo();// 初始化页面信息

            SelectUser();// 查找组里面的所有用户

            DataCheck();

 

        }

获取行展开改变事件 DetailRowExpandedChanged

        protected void gvGroup_DetailRowExpandedChanged(object sender, ASPxGridViewDetailRowEventArgs e)

        {

 

            SYSolution_WebUI.ServiceReference.GroupInfo groupInfoModel = (SYSolution_WebUI.ServiceReference.GroupInfo)((ASPxGridView)sender).GetRow(e.VisibleIndex);// 获取选中行实体

            ASPxGridView gv = (ASPxGridView)gvGroup.FindDetailRowTemplateControl(e.VisibleIndex, "gvGroupName");   // 获取模板内aspxgridView ID名称

            SYSolution_WebUI.ServiceReference.GroupInfo[] model = client.GroupSelUserList("GroupId='" + groupInfoModel.GroupId + "'");// 通过组ID值获取实体对象

            if (model[0].UserInfoList != null && gv != null)// 当用用户列表值与子aspxgridView不为空

            {

                gv.DataSource = model[0].UserInfoList;      // 子aspxgridView绑定数据源

                gv.DataBind();

            }

            if (model[0].UserInfoList[0].Name == "")       // 如果子aspxgridView中的用户列表为空时不显示 不展开

            {

                gvGroup.SettingsDetail.AllowOnlyOneMasterRowExpanded = false;

            }

        }

排序事件中重新绑定数据 BeforeColumnSortingGrouping

       protected void gvGroup_BeforeColumnSortingGrouping(object sender, ASPxGridViewBeforeColumnGroupingSortingEventArgs e)

        {

            gvGroup.DetailRows.CollapseAllRows();// 关闭所有DetailoRow

 

            gvGroup.DetailRows.ExpandRow(3);

        }

重绑定数据使用时先选中行，再查看 FocusedRowChanged

Protected void aspxGridView_FocusedRowChanged(object sender,EventArgs e){}

行列绑定数据事件CustomUnboundColumnData

Protected void aspxGridView_CustomUnboundColumnData(object sender,EventArgs e){}

 

.隐藏编辑列，在DataBound事件中
protected void ASPxGridView1_DataBound(object sender, EventArgs e)
    {
        if(ASPxGridView1.VisibleRowCount>0)
        {
            //ASPxGridView1.Columns[命令列索引]
            (ASPxGridView1.Columns[4] as GridViewCommandColumn).NewButton.Visible = false;
        }
    }
