  protected void maintaintimetablegrid_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
        {
            if (e.Item is GridEditFormItem && e.Item is GridEditableItem && e.Item.IsInEditMode)
            {
                RadComboBox formRadclass = e.Item.FindControl("formRadclass") as RadComboBox;
                if (formRadclass != null)
                {
                    formRadclass.AutoPostBack = true;
                    formRadclass.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(formRadclass_SelectedIndexChanged);
                }
                RadComboBox formRadSubject = e.Item.FindControl("formRadSubject") as RadComboBox;
                if (formRadSubject != null)
                {
                    formRadSubject.AutoPostBack = true;
                    formRadSubject.SelectedIndexChanged += new RadComboBoxSelectedIndexChangedEventHandler(formRadSubject_SelectedIndexChanged);
                }

            }

        }
        void formRadclass_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            //first reference the edited grid item through the NamingContainer attribute
            GridEditableItem editedItem = (sender as RadComboBox).NamingContainer as GridEditableItem;
            RadComboBox formRadroom = editedItem.FindControl("formRadroom") as RadComboBox;
            if (formRadroom != null)
            {
                formRadroom.Items.Clear();
                RadComboBoxItem item1 = new RadComboBoxItem();
                item1.Text = "Select Room";
                formRadroom.Items.Add(item1);
                formRadroom.DataSource = Calendermanager.sch_view_class_default_room((editedItem.FindControl("formRadclass") as RadComboBox).SelectedValue.GetInteger());
               formRadroom.DataBind();
            }
            RadComboBox formRadSubject = editedItem.FindControl("formRadSubject") as RadComboBox;
            if (formRadSubject != null)
            {
                formRadSubject.Items.Clear();
                RadComboBoxItem item2 = new RadComboBoxItem();
                item2.Text = "Select Subject";
                formRadSubject.Items.Add(item2);
                int? faciltyid = LogonDetails.Instance.sys_lclvar_default_facility_id;
                formRadSubject.DataSource = classmarksheetmanager.sch_view_class_subject_lookup((editedItem.FindControl("formRadclass") as RadComboBox).SelectedValue.GetInteger(), faciltyid);
                formRadSubject.DataBind();
            }

        }
        void formRadSubject_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
        {
            //first reference the edited grid item through the NamingContainer attribute
            GridEditableItem editedItem = (sender as RadComboBox).NamingContainer as GridEditableItem;
            RadComboBox formRadTeacher = editedItem.FindControl("formRadTeacher") as RadComboBox;
            if (formRadTeacher != null)
            {
                formRadTeacher.Items.Clear();
                RadComboBoxItem item1 = new RadComboBoxItem();
                item1.Text = "Select Teacher";
                formRadTeacher.Items.Add(item1);
                formRadTeacher.DataSource = Calendermanager.sch_view_class_subject_teacher_lookup((editedItem.FindControl("formRadclass") as RadComboBox).SelectedValue.GetInteger(), (editedItem.FindControl("formRadSubject") as RadComboBox).SelectedValue.GetInteger());
                formRadTeacher.DataBind();
            }
