    MVC GridPanelFor example with batch update


    does anybody have an example of using batch update with GridPanelFor.

    I've followed this example: Grid with batch saving

    But don't know how to get the store of the GridPanel.

    I've tried the following without success as panel.GetStore() returns null:

            public ActionResult HandleItemChanges(StoreDataHandler handler)
                var panel = (this.GetCmp<GridPanel>("PricePanel"));
                var store = panel.GetStore();
                foreach (SubscriptionItem created in items.Created)
                    var record = store.GetByInternalId(created.PhantomId);
                    record.CreateVariable = true;
                    created.PhantomId = null;
                foreach (SubscriptionItem deleted in items.Deleted)
                foreach (SubscriptionItem updated in items.Updated)
                    var record = store.GetById(updated.OldItemId);
                return this.Direct();
    Can anyone advise how to commit the changed store records?

    Thanks in advance

    the DataSource of Store is disposed(release),when you databind(),you just can use
    <ext:Parameter Name="rows" Value="Ext.encode(#{GridPanel_File}.getRowsValues())" Mode="Raw"></ext:Parameter>
    to get rows

    Problem is accessing the store of the GridPanel in code behind

    Hi LikeWatchStar,

    thanks for your response.

    We can get the records of the GridPanel without any problem:

                                            .DirectEvents(de =>
                                                de.Click.Url = Url.Action("HandleItemChanges");
                                                de.Click.ExtraParams.Add(new Parameter()
                                                    Name = "__RequestVerificationToken",
                                                    Value = "App.AntiForgery.getValue()",
                                                    Mode = ParameterMode.Raw
                                                de.Click.ExtraParams.Add(new Parameter
                                                    Name = "data",
                                                    Value = "this.up('window').down('component[itemId=PricePanel]').store.getChangedData()",
                                                    Mode = ParameterMode.Raw,
                                                    Encode = true
    The issue we are facing is how to get the store of the gridpanel in the code behind. We need the store to be able to commit the records after the database has been updated.
