页面回传的时候调用checkbox的OnCheckedChanged事件

Question

 protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                this.erdWidget.RetrieveingData += new RetrieveingGridDataEvent(erdWidget_RetrieveingData);
                erdWidget.BindGrid();
                BindDataToCheckBox(State.MaintainFavWidget.FavWidgetListResultUpdate);
            }
            
        }

 

页面回传的时候

 #region refresh the grid
        protected void radAjaxManageOne_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if (e.Argument == "Rebind")
            {
                erdWidget.MasterTableView.SortExpressions.Clear();
                erdWidget.MasterTableView.GroupByExpressions.Clear();
                erdWidget.RetrieveingData += new RetrieveingGridDataEvent(erdWidget_RetrieveingDataTwo);
                erdWidget.BindGrid();
            }
            else if (e.Argument == "RebindAndNavigate")
            {
                erdWidget.MasterTableView.SortExpressions.Clear();
                erdWidget.MasterTableView.GroupByExpressions.Clear();
                erdWidget.MasterTableView.CurrentPageIndex = erdWidget.MasterTableView.PageCount - 1;
                erdWidget.Rebind();
            }
        }
        #endregion
        #region bind data to grid after update op
        protected IEnumerable erdWidget_RetrieveingDataTwo(object source, Framework.Controls.ExtendedRadGridRetrieveingDataArgs args)
        {
            BindDataToCheckBox(State.MaintainFavWidget.FavWidgetListResultUpdate);
            return State.MaintainFavWidget.FavWidgetListResultUpdate;
        }
        #endregion

checkbox数据绑定和onchanged事件

    #region  bind data to checkbox
        protected  void BindDataToCheckBox(IEnumerable<WidgetEntity> widgetEt)
        {
            int i = 0;
            foreach (GridDataItem dataItem in erdWidget.MasterTableView.Items)
            {
                if(widgetEt.Count()>0)
                {
                    (dataItem.FindControl("cbFavWidget") as CheckBox).Checked = widgetEt.ToList()[i].FavWidget;
                }
                ++i;
            }
        }

        protected void WidgetRowSelection(object sender, EventArgs e)
        {
            ((sender as CheckBox).NamingContainer as GridItem).Selected = (sender as CheckBox).Checked;
        }
        #endregion

 

 

 

现在时页面回传的时候  protected  void BindDataToCheckBox(IEnumerable<WidgetEntity> widgetEt)这个数据绑定函数要执行。但是不执行OnCheckedChanged事件。在grid控件中得checkbox全部变为false了？？？

这个需要Checkbox的唯一ID，你可以去grid行号来作为checkbox的ID
