[Solved] How to access specific data in series when sending grouped data to a view [MVC]

Hey guys. I'm new to Kendo UI and basically to MVC framework but that is the tool I have to use so... :)

In the example below IEnumerable is used to simply enumerate over entire data stored in Close.
But if I send data as a List

@model List<Kendo.Mvc.Examples.Models.StockDataPoint>

and later would like to access specific data(not all data like hereseries.Column(model => model.Close) ) how could I do that exactly ?

http://demos.kendoui.com/dataviz/bar-charts/grouped-data.html

@model IEnumerable<Kendo.Mvc.Examples.Models.StockDataPoint>

<div class="chart-wrapper">

@(Html.Kendo().Chart(Model)

.Name("chart")

.Title("Stock Prices")

.DataSource(dataSource => dataSource

.Read(read => read.Action("_StockData", "Scatter_Charts"))

.Group(group => group.Add(model => model.Symbol))

.Sort(sort => sort.Add(model => model.Date).Ascending())

)

.Series(series => {

series.Column(model => model.Close)

.Name("#= group.value # (close)");

})

.Legend(legend => legend

.Position(ChartLegendPosition.Bottom)

)

.ValueAxis(axis => axis.Numeric()

.Labels(labels => labels

.Format("${0}")

.Skip(2)

.Step(2)

)

.CategoryAxis(axis => axis

.Categories(model => model.Date)

.Labels(labels => labels.Format("MMM"))

)

</div>

Date validation not working. Anyone have any ideas...

Here is my page with the code and the script, basically the validator does not validate the date. I don't know how to make the control get validated by the custom rule. You can do control F $("#service").kendoValidator to see the where the validation is called and configured.

Router routeMissing problem

Hello,

In my SPA (not mobile) application i'm using the Kendo Router for navigation within the application.
The Router works perfect except for 1 problem i'm running into.
When someone navigates to an invalid route it's caught through the routeMissing method to prevent navigating to invalid routes.
So navigating from http://mysite/#/myView to http://mysite/#/myViewtest results in the routeMissing being called and the navigation is prevented.
However, the browsers address bar shows the address which was navigated to (http://mysite/#/myViewtest).
If the user hits the browsers refresh button after that the application starts again and tries to navigate to the wrong address, which now results in a blank page.
Trying to navigate back to the old route in the routeMissing method doesn't work, since it didn't acually change for the router (defaultPrevented).

Is there any way to navigate to the old route or update the address bar with the old route ?

Thanks in advance.

How and when globalize.js can be used by Kendo UI?

I include globalize.js and globalize.culture.xx-XX.js befor Kendo UI scripts. Then I try execute "Globalize.culture("xx-XX")" and "kendo.culture("xx-XX")" in all possible combinations. From http://docs.kendoui.com/getting-started/framework/globalization/overview: "When globalize.js is registered before Kendo scripts, then Kendo will use globalize.js features instead of Kendo Globalization."

What does it mean? Does it mean for example that I can miss kendo.culture.xx-XX.js and DatePicker will still show localized months and week days? I try - it does not. So when, where and how Kendo UI uses globalize.js?

KendoUI with Parse.com

Hi,

I created an Icenium mobile app that utilizes Kendo UI and Parse.com. I have already developed a Facebook Login function for the app. Now i Need the following additional functions:

- post a message ("Event") with some additional fields and select a Location via Google Maps
- search for events at a specific Location or at the current Location, result should be Shown either as a list or in map
- when launching the app, it Show automatically all Events near the current Position in a map
- when selecting an Event, it should Show up in a Detail view

Is there anybody out there who could accomplish this? (paid of course)

Best Regards
Jörg

[Solved] Inline header filter row with groupable and pageable grid

I've extended a suggestion to my purposes from this post:
http://www.kendoui.com/forums/kendo-ui-web/grid/grid-header-filtering-row-that-contains-1-element-for-each-column-in-grid-with-the-same-width.aspx

I've gotten it to work very well with my grid implementation. The only problem I've run into that I'm not sure how to solve so far is that when a column is dragged to the group header it aligns the headers with my filter row just fine, but if you then go to page 2, the headers are suddenly misaligned though the filter row stays in place.

You can see what I mean in this jsfiddle. It seems the <th> element that's added to the header row to indent the rows and align the grid is being removed somehow

Any suggestions about how to correct this behavior would be greatly helpful.

Edit: Actually, paging doesn't seem to matter. Just whenever the grid repaints as it also happens when filtering after grouping or grouping a second column.

Multiple kendo.mobile.Application instances

Working on a Single App-page designed for tablets/desktops so we want to have a mobile look and feel.
Right now i am looking at 3 kendo.mobile.Application instances.
-one for the main page(2 views: 'main_page' and 'details_page'), also we have 2 way drawer planned for it.
-one app for the right drawer(a filters list(main view) and a new view for each filter 'edit mode')
-one app for the left drawer(a hierarchical list)
Working on this, but i have doubts.
Let me know if this should work(theoretically).

Thanks
