Grouped Data & Multi-axis chart (ASP.NET MVC)

Hi,

Is it possible to have a multi axis chart using grouped data?

Country Project Product Date

Philippines Project1 Product A 1-May-13

Philippines Project1 Product B 1-May-13

Philippines Project1 Product C 1-May-13

Japan Project2 Product D 3-Jun-13

Japan Project2 Product E 3-Jun-13

I have the above data and I need to show a line chart of the number of distinct Projects per country per month in the firs axes and on the 2nd I want to show the number of Products per country per month in a column chart.

On the CategoryAxis is the date field and I've set the ChartAxisBaseUnit to Months.

The line chart seem to be working fine but he column chart isn't displaying as expected.

I could use some help.

Thanks,
Ronald

Grid sort no longer working in version 2013.2.716, sort is undefined

Hi

I have upgraded Kendo UI for ASP.NET MVC to version 2013.2.716 from 2013.1.319 (to fix grouping issue in IE8, which it has) but now the grid sort functionality is no longer working. In Fiddler I can see the sort value is 'undefined-asc' so the sort column is not getting set.

Is this an issue you are aware of and can help fix?

Kind regards
David

Culture file kendo.culture.fr-CA.min.js and calendar

How I can use it correctly. All accent are broken when I use this culture with calendar. A got wierd caracter instead. I try to open the file directly from the browser, same thing. But file open with "normal" text editor are OK. Do I need to set the charset in the js file? I try to set it to UTF8 in the <script> definition without success.

Prevent elastic scrolling

Hi,
I am evaluating Kendo UI framework to build cross device app!

I've put together a few Views and it looks good so far.
As I am trying it out on iPad, I noticed that the elastic scrolling behavior gives the app non-native like behavior!

If the web app is flicked past the bottom or top of the page, the page would elastically get tugged away from
the header or footer bar (essentially bottom/top of the screen).

How do I prevent the elastic scrolling in views so that the app behaves like native app (without elastic scrolling)?

I've tried setting the view scroller elatic property false on the view's data-init function and that didn't help.
Here is the two lines I've put in data-init function:
var scroller = e.view.scroller;
scroller.setOptions({ elastic: false });

(Found a few suggestions on the internet like blocking touch move on body, setting overflow to hidden on body
and none of them helped!).

Please let me know how to prevent elastic scrolling.
Thanks.

CustomTemplate not displaying in toolbar for internal build kendoui.aspnetmvc.hotfix.2013.2.813.commercial

I have just had to upgrade to kendoui.aspnetmvc.hotfix.2013.2.813.commercial to fix some other issues with this control. However it now appears that the CustomTemplate is not displaying in the toolbar. I did note that in this package the dll is still version 2013.2.729.340, however it did fix my bug from the original 2013.2.729 major build.

Are you able to have a look at this and tell me if there is a quick fix

@(Html.Kendo().Editor()

.Name("sectionBlockEditor")

.HtmlAttributes(new { style = "width: 900px;height:530px" })

.Tools(tools => tools

.Clear()

.Formatting()

.CustomTemplate(ct => ct.Template("<label for='templateTool' style='vertical-align:middle;'>Background:</label> <select id='templateTool'><option value=''>none</option><option value='\\#ff9'>yellow</option><option value='\\#dfd'>green</option></select>"))

)

That didnt work although it should.

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?
