[Solved] Ordering with localized data entities

Hello everyone, I'm trying to populate a grid with localized data.
My codefirst entity framework database look like this:

public class Prod

{

public int ProdId { get; set; }

public int Quantity { get; set; }

//Other Properties & Navigation Properties

public ICollection<ProdLang> ProdLangs { get; set; }

}

public class ProdLang

{

public int ProdLangId { get; set; }

public int LangId { get; set; }

public string Name { get; set; }

public string Description { get; set; }

//Other Properties

public int ProdId { get; set; }

public Prod Prod { get; set; }

}

I want to show in my kendo grid Collection of Product with ProdLang properties for current user language (eg. Name, Description)
For doing that i buil a flattened class, like this:

public class ProdView

{

public int ProdId { get; set; }

public int Quantity { get; set; }

public string Name

{

get

{

return ProdLangs.Single(pl => pl.LangId == langId).Name;

}

public string Description

{

get

{

return ProdLangs.Single(pl => pl.LangId == langId).Description;

}

//Other Properties & Navigation Properties

public ICollection<ProdLang> ProdLangs { get; set; }

}

My problem is that I want to let user to order & paging data, but I don't want to load entire collection everytime I have to display grid and pass it to "ToDataSourceResult" method.

There is a way for loading from the DB only the desired data?

Thanks

Adding generated HTML to DOM to create Drawer

I am trying to create a dynamic drawer widget on initialization of a view, since there is not programmatic way to create a drawer widget I build the drawer HTML like so:

<div data-role="drawer" id="my-drawer" style="width: 270px"

<ul id="nav" data-role="listview" data-type="group"

<li

>Navigation

<ul

<li data-icon=home><a href=views/index.html data-transition="none">Menu A</a></li> </ul

<ul

<li data-icon=search><a href=views/weather.html data-transition="none">Menu B</a></li> </ul

<ul

<li data-icon=compose><a href=views/location.html data-transition="none">Menu C</a></li> </ul

</li

<li

>Account

<ul

<li data-icon="settings">Settings</li

<li data-icon="off">Log Out</li

</ul

</li

</ul

</div>

I then append this generated HTML to the DOM but it is not "kendorized" so it doesn't act as the drawer widget would. When I click to open the drawer I get the following error message: Uncaught TypeError: Cannot call method 'openFor' of undefined

I need help getting this to work properly. Thanks

Getting ValueAxis Properties

Is there a way to get (not set) the valueAxis' min/max/majorunit values? I only seem to be able to access those properties if I actually set them first.

I want to be able to know what the values have been automatically set to by Kendo and determine if I need to fine tune the scaling.

Thanks.

Endless-scrolling fast on iPhone but slow on Android and Windows Phone

Hi,

I've added native scrolling to all mi views on my app and the performance is awesome, just like a native app.

But if we combine a ListView with "pull to refresh" or "endless-scrolling" and native-scrolling does not work. Any way to fix it? Why in Chrome for Windows Desktop this feature is supported and work? what about mobile browsers?

please

Lining Up Category Axes On A Multi-Axis Chart

I have a chart that has two category axes defined so I can display the category labels at the bottom of the chart when there are negative values. I am also setting min and max values for the second axis to avoid labels that show up as 0.25, 0.5, etc. when the series has small values like 1.

I would like to know if there is a simple way to line up the category axes of different series. If you see the attached image, you can see how the first series has a negative value and the second series starts below it.

Thanks.

Filtering inside dataBound event goes into recursion

Hi,
I'm trying to filter data inside dataBound event function, but it creates recursive calls to itself.
Could you tell me if this is a bug or am I doing something wrong?

Example: http://trykendoui.telerik.com/onAj
This is Event example from grid demos with modification inside "function onDataBound(arg)".

function onDataBound(arg) {
                    kendoConsole.log("Grid data bound");
                     var l_Data = this.dataSource;
                    l_Data.filter( {
                       field: "UnitsInStock",
                       operator: "eq",
                       value: 39
                       } );
                }

[Solved] Data-reload and tabstrip issue

Hi, I have a problem with navigating between two remote views, where one view has the data-reload=true attribute.

I have a remote view which show details of a message, you can then post this message on twitter. If the user didn't authorize twitter before, they get a message with that they have to do that. The user then has two options: authorize twitter or go back to the message. If back to the message is selected, the tabstrip in the data-reload view dissappears and reappears immediatly.

This problem wont happen when data-reload is set to false. But if i set it to false the data in the remote view wont update. when another message is selected.

How can I make sure the tabstrip doesn't flicker when navigating back to the remote view with the data-reload true attribute.

-EDIT:
When i go to the remote view with data-reload=true for the first time no flicker appears only for second time and the times after that.

Distinguish operations in change event.

Hi.

How can I distinguish operations in change event? I mean, how to recognize whether current operation is select (add new item) or delete (cross clicked)?
I know about select event, but I'm interested in change event only? Should I use external counter?

Thanks in advance.
