Is multi filter supported for treelist columns or is there another way to do this?

Filterable(f => f.Multi(true)) 

Hi guys,

I've been struggling with this for several hours with no luck. I have this grid with batch editing enabled and I have two buttons that need to be hidden conditionally depending on the value of a property in my ViewModel. I'm using the dataBound event to hide the buttons and everything works fine until I edit one of the cells in the grid. As soon as I change the value on a cell and exit the edit mode the button that was hidden appears again. How can I solve this?

Thanks in advance.

When setting a value to an object in the model, the following error appears:

            Uncaught TypeError: Cannot read property 'open' of null

The stack trace finishes with this line:

            Widget.extend._createContentElement @ kendo.web.js:67057

that on the kendo.web.js translates to the following: 

             doc.open();

The stack trace starts with this line:

              vm.homework.set("timetableId", -1);​

The vm object is the "virtual model" it is an instance of the kendo.observable model, homework is an object of the model, it is check if it's initialize before setting it like this:

 if (vm.homework !== undefined) {
            vm.homework.set("id", -1);
            vm.homework.set("timetableId", -1);

            vm.homework.set("title", "");

What is weird is that the "vm.homework.set("id",-1)" doesn't throw the exception.

I tried changing the set to "vm.homework.timetable=-1" it does not throw the error, but the error persist on the next "set" line.

I'll attach a screen shot of the hole stack trace.

The kendo.observable is set like this:

models = (function (models) {
    models.homeworkModel = kendo.observable({
        homework: {
            id: -1,
            timetableId: -1,
            title: "",
            details: "",
            availableTime: new Date(),
            dueDate: new Date(),
            lessonGroupId: null,
            isLessonAssign: true,
            links: [],
            homeworkStudents: [],
            homeworkResources: []
        },

        lesson: -1,

        //Behaviour
        init: init,
    });

    var vm = models.homeworkModel;

    return models;

function init(lessonId) {
        $.blockUI();
        resetVm();
        vm.homework.set("timetableId", lessonId);
        vm.set("lesson", lessonId);
    }

function resetVm() {
        if (vm.homework !== undefined) {
            vm.homework.set("id", -1);
            vm.homework.set("timetableId", -1);
            vm.homework.set("title", "");
            vm.homework.set("details", "");
            vm.homework.set("availableTime", new Date());
            vm.homework.set("dueDate", new Date());
            vm.homework.set("isLessonAssign", true);
            vm.homework.set("lessonGroupId", null);
            vm.homework.set("links", []);
            vm.homework.set("homeworkStudents", []);
            vm.homework.set("homeworkResources", []);
        }
    }

})(typeof models != "undefined" ? models : {});​

Hi there,

I have a scheduler enabled in week and day view.  Each 1hr period per day has 1 item returned which is a template to encapsulate the items for that date (we couldn't use it out of the box before of our peculiar client requirements which require it to be very dynamic) - which works fine, but the result is that a lot of markup is returned via JSON from my controller.  It all works fine in day view, but in week view after adding more than a few days' worth of items the .read() method from javascript I call after an item is removed or added stops working - the spinner fires and the controller method is hit correctly, but it never re-renders the scheduler with the updated data.

I suspect it's a limit being hit somewhere - is there such a thing for the scheduler, as I can't find one anywhere?

Or do you have any advice for a better way to achieve this scenario?  I could return more raw data rather than HTML from the controller, but I'd essentially need to loop through multiple items inside an individual scheduler item and apply a template for each, which I don't think is possible?

Thanks,

Mark

I'd like to use the spreadsheet widget, but via angular. I tried something like this:

    <div class="container-fluid" ng-controller="planner.PlanEditorController as shot_planner">

        <H1>Planner</H1>

        <kendo-spreadsheet style="height:580px;" options="planner.spreadsheetOptions"></kendo-spreadsheet>

    </div>

 but it doesn't seem to be working (the directive is not recognized).

 Any ideas?

Thanks,

John

Details about my grid:

Kendo version 2014.2.716

Grid has the following features:Configured by Razor GridBuilder, loaded via ajax, no page size (grid scrolls internally), grouped, each row has an expandable detail row, and 6 monetary columns are aggregated, with aggregates shown in both the group footer and grid footer.

Problem: We want aggregates to update whenever you change a value in the grid.

Solution #1: Consensus seems to be to call e.sender.dataSource.fetch();  That worked, but had the following consequences:

(1) Clears dirty indicators in cells, (2) Clears any open detail rows, (3) Opens any collapsed groups.

We can solve all three of those problems manually, but it's getting to the point where I wonder if just manually updating the aggregates, for finding another way other than re-fetching would be a better solution than hacking the grid back to its pre-fetch state.  What made it extra difficult is the rows and cells are all re-created, so it's not as easy as just tracking a list of dirty cells, and marking them dirty again; you'd have to track the rowid/cellindex pair, and find the equivalent new cells.

Does anyone have any suggestions?

Is it possible to use the DataSourceRequest object as an action method parameter? What I've got currently is a grid that loads data, but then won't filter or sort. The paging seems to work.

I'm using Kendo UI verison 2015.3.930.

Thanks!

Hello,

Thanks,
