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???
