Grouping and Selection doesn't work with jquery 1.8.1 or later

Hi all

I have working the Kendo grid with jquery 1.7.2, but I upgraded it to 1.8.1 and grouping and selection features stopped working.

I would know if next version of Kendo will be compatible with these version of jquery and when will be available for download?

Thanks

Esteban.-

Adding custom class to numerictextbox

I seem to be having an issue where the numerictextbox widget does not pull the custom class assigned to the original input field.

The combobox and other widgets seem to do as expected, and add the original class to span.k-widget, however it doesn't seem to be happening ok span.k-widget.k-numerictextbox

Any ideas? Is this a bug, or is this expected behavior? If it is expected, how does one go about adding a custom class (or id) to span.k-widget.k-numerictextbox?

Thanks in advance for your help.

Here's a js fiddle to show you what's happening: http://jsfiddle.net/MCCPs/4/

How do you filter based on Blank/Empty field values?

I have implemented the KenoUI javascript Grid within an application. I have the filtering all working correctly, except it seems the KendoUI Grid doesn't support the ability to filter blank/emtpy field values.

Basically, in the filter dropdowns, I need there to be a "Blank" option that allows for only items where that field is either null or an empty string. How do you add this option to the dropdown?

I need an example of saving MVVM model with view controller

I am fairly new to MVC
I have tried all day to use the MVVM Remote Binding example to update the model using form post instead of json to post to a controller action and it won't map the post data to the IEnumerable<ProductViewModel> products argument of my controller action. I have inspected the post parameters and this is what I see:

models[0][Discontinued]	`false`
models[0][ProductID]	`3`
models[0][ProductName]	`Aniseed Syrup`
models[0][UnitPrice]	`12`
models[0][UnitsInStock]	`13`
models[0][UnitsOnOrder]	`0`

In the working example for Kendo Grid Editing Custom, I noticed that the post parameters should be more like this:

models[0].Discontinued	`false`
models[0].ProductID	`3`
models[0].ProductName	`Aniseed Syrup`
models[0].UnitPrice	`12`
models[0].UnitsInStock	`13`
models[0].UnitsOnOrder	`0`

Notice how the properties are not indexed. I am guessing that this is why it doesn't work.

Does anyone have a working example (with controller source) of Kendo MVVM being used to update the model?

View 'beforeShow' event example

Hello,

First off, thanks for putting together a great suite of controls. You've made my life as a mobile environment developer much easier! I do have a question though. I see in the release notes and in the documentation that the mobile View supports an event called "beforeShow". Is there an example somewhere that utilizes that event? I'm trying to wire up some logic around the browser's back button and I'd like to use that event to determine if the user is logged in before displaying the requested view. When I try to attach a handler to the event like so:

<div data-role="view" id="someView" data-show="showSomeView" data-beforeShow="viewBeforeShow">

/* div content here */

</div>

The viewBeforeShow method never fires. The showSomeView event works as expected, but the user is able to navigate back to that view even though they are no longer logged in to the app (exactly the case I'm trying to prevent).

Here is the code for viewBeforeShow:

function viewBeforeShow(view) {

if(loggedOut == true) { // loggedOut is just a global variable for now

window.kendoMobileApplication.navigate('#loginView'); // loginView is the login mobile view

}

I don't know if this is the correct way to handle this scenario, but I can figure that out once I start handing the event.

I should mention I'm using the trial version 2012.2.710 (just downloaded it today). I will eventually translate this to the licensed version for my employer, but I was trying a proof of concept before I worried about that.

Is this the right way to configure the handler for this event? Any help would be greatly appreciated.

Thanks again for the great work!

How to add rows using MVC model

I have a models
Route:
int RouteID;
String RouteName;
IEnumerable<RouteCustomer> Customers;

RouteCustomer:
int RouteID;
int CustomerID;
int Sun;
int Mon;
int Tue;
int Wed;
int Thue;
int Fri;
int Sat;

Customer:
int CustomerID;
String Name;

I have created an edit form that allows changes (route name) and a grid for the customer information. What is happening now is that I am not getting the events I need when adding a new row to the grid:

Here is the grid code:

@(Html.Kendo().Grid<LightRouteDB.RouteCustomer>()

.Name("CustomerGrid")

.Columns(cols =>

{

cols.Bound(r => r.CustomerID);

//cols.Bound(r => r.Customer.CustomerName);

cols.Bound(r => r.Sun);

cols.Bound(r => r.Mon);

cols.Bound(r => r.Tue);

cols.Bound(r => r.Wed);

cols.Bound(r => r.Thu);

cols.Bound(r => r.Fri);

cols.Bound(r => r.Sat);

cols.Command(command => { command.Edit(); command.Destroy(); }).Width(200);

})

.ToolBar(toolbar => toolbar.Create())

.Editable(editable => editable.Mode(GridEditMode.InLine))

.Pageable()

.Sortable()

.Scrollable()

.DataSource(ds => ds

.Ajax()

.Events(events => events.Error("error_handler"))

.Model(m => { m.Id(p => p.RouteCustomerID); m.Field(f => f.RouteID).DefaultValue(Model.Route.RouteID); })

.Create(a => a.Action("CreateCustomerRow", "Routes"))

.Read(r => r.Action("ReadCustomerRows", "Routes"))

.Update(u => u.Action("UpdateCustomerRow", "Routes"))

.Destroy(d => d.Action("DestroyCustomerRow", "Routes"))

)

And here is the controller:

public ActionResult ReadCustomerRows(int id, [DataSourceRequest] DataSourceRequest request)

{

return Json(getRouteCustomersFromSession().ToDataSourceResult(request));

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult CreateCustomerRow(int id, [DataSourceRequest] DataSourceRequest request, RouteCustomer customer)

{

if (customer != null && ModelState.IsValid)

{

IList<RouteCustomer> rc = getRouteCustomersFromSession();

rc.Add(customer);

}

return Json(new[] { customer }.ToDataSourceResult(request, ModelState));

}

[AcceptVerbs(HttpVerbs.Post)]

public ActionResult UpdateCustomerRow([DataSourceRequest] DataSourceRequest request, RouteCustomer customer)

{

if (customer != null && ModelState.IsValid)

{

IList<RouteCustomer> rc = getRouteCustomersFromSession();

var target = rc.Where(c => c.RouteCustomerID == customer.CustomerID).First();

if (target != null)

{

target.CustomerID = customer.CustomerID;

saveRouteCustomersToSession(rc);

}

return Json(ModelState.ToDataSourceResult());

}

The events in the controller just don't seem to fire. I thought I copied it from the sample programs, but it doesn't seem to work correctly. Any help would be appreciated.

    $(document).ready(function () {
        $("#editor").kendoEditor({
            tools: [
                "bold",
                "italic",
                "underline",
                "strikethrough",
                "fontName",
                "fontSize",
                "foreColor",
                "backColor",
                "insertHtml",
            ],
            insertHtml: [
                { text: "Request.FirstName", value: "#Request.FirstName#" toolTip: "Inserts users first name" },
                { text: "Request.BirthDay", value: "#Request.BirthDay#" toolTip: "Inserts users date of birth" }
            ]
        });
    });

[Solved] Remove view - parameterized

Edit: I have a typo in the thread title, it should be "Remote view..." not "Remove".

I am writing a mobile web app that leverages the Kendo UI Mobile 'Application' object. In one part of the application I am walking a user through selecting a vehicle (year first, then make, then model, etc). Each of these selections is on it's own page. Each list is retrieved from a back-end service. The 'make' depends on the 'year' selected, and the 'model' depends on 'year' and 'make'. I had built a small utility function that would parameterize the URL I send to the Kendo application's navigate() method and it was working great on version 2012.2.710. However, in another area I ran into this bug (http://www.kendoui.com/forums/framework/mvvm/bug-nested-array---source-binding.aspx) and was forced to upgrade to 2012.2.913. This fixes the bug but now there's some code in the navigate() method that strips of any query parameters from the url.

So, I was doing this:

app.navigate('/Home/SelectMake?year=2012');

and now (version 913) Kendo ends up basically doing this:

app.navigate('/Home/SelectMake');

So my question is this: Is there a recommended way to load remote views with parameters? If not, why was the code added that strips the query parameters when navigating (as this breaks my code now)?

Thanks.

[Solved] Resizing objects in panelbar cause panel height issues

I have found that if you put a paginated grid with auto height in the panelbar, when you change pages and the grid height changes, the panelbar doesn't keep up with the grid size changes. I suppose I could maybe detect when the grid page changes and somehow refresh the panel its in to fit maybe?
