In two seperate views I have similar code. The guts are the same yet the results of the binding framework differ. Could you please elaborate on the following discrepancy?
The first view is delcared as

<div data-role="view"

data-title="Form Unexpected but nice"

data-init="ns.viewA.init"

data-before-show="ns.viewA.beforeShow"

data-show="ns.viewA.show"

data-model="ns.viewA.viewModel">

...

<select data-bind="source:options,value:selectedOption"

data-text-field="display"

data-value-field="id"></select>

...

</div>

The second as

<div data-role="view"

data-title="Form Expected"

data-init="ns.viewB.init"

data-before-show="ns.viewB.beforeShow"

data-show="ns.viewB.show"

data-model="ns.viewB.viewModel">

...

<form>

...

<select data-bind="source:options,value:selectedOption"

data-text-field="display"

data-value-field="id"></select>

...

</form>

</div>

viewA is a read-only/navigational view for traversing a hierarchy and inspecting details of the current node.
viewB is an edit view for the one such node in viewA.

The discrepancy is that in viewA, when selectedOption changes, the value of selectedOption is the actual object, not the id of the object.
However, in viewB, value of selectedOption is properly set to the ID of the option selected from the drop down.

I've tried changing the markup around each to see if i could get matching behaviors from the two, however, I've not been able to replicate
identical behavior between the them. Any ideas why this occurs?

using Razor & remote links?

Is there a way to use external links, equivalent to using the data-rel="external"?

I have this and I am trying to open the log out link outside my app so the # is not appended.
items.AddLink().Icon("settings").Url("Logout","Account").Text("Settings");

DataSource transport with function

Hi,

According to DataSource Transport API, I am using the following code for my transport:

01.var historyTransport = {

02. read: function (options) {

03. $.ajax({

04. url: "../../AppData/Batch/History.json",

05. dataType: "json",

06. success: function (response) {

07. // notify the data source that the request succeeded

08. console.log('successfully load History.json');

09. var rows = [];

10. $.map(response.rows, function (n,i) {

11. var obj = { status: n.cell[0] };

12. rows.push(obj);

13.

14. });

15. var historyData = {};

16. historyData.rows = rows;

17. options.success(historyData);

18.

19. },

20. error: function (response) {

21. // notify the data source that the request failed

22. console.log('failed to load History.json');

23. }

24. });

25. }

26.}

I am having a very strange problem with this options.success function. my json object from the ajax response looks like this

Object {rows: Array[7675], page: 1, total: 1, records: "1"}

options.success() has no problem to parse it. However, if i want to do some reformatting by creating a separate object historyData, i will have an error from options.success() saying TypeError: Cannot call method 'slice' of undefined, unless i name the array property of historyData - rows.

it almost feels like the DataSource options.success() function is expecting an array called rows. it was pure coincident that my original json contains this rows property.

can anyone help to explain whether my finding is true? and what exactly is this options parameter? there is no document about it.

Thanks
amp

Hi,

The problem here is obvious. The autoScale for value axis is not working for some reason. I can set up min and max value which works but the data comming from server can vary greatly so we really need autoscale option.
here is the code. Any help or point st the right direction would be appreciated. thanks

function createSalesChart() {

return $("#report-sales-chart").height(400).kendoChart({

title: "Sales Report Chart",

dataSource: chart_data,

autoBind: false,

seriesDefaults: { type: "line", stack: false, missingValues: "interpolate" },

series: [

{

field: "Gross_Total",

name: "Gross Total",

groupNameTemplate: "#= group.value # (#= series.name #)",

//name: "#= group.value # (#= series.name #)",

groupName: "#= group.value #",

axis: "currency"

}

],

categoryAxis: {

field: "Date",

baseUnit: "days",

labels: {

format: "MMM",

skip: 4,

step: 4

}

},

valueAxis: {

name: "currency",

/* autoScale: true,

AutoScale: true,

autoscale: true,*/

color: "blue",

labels: { format: currency_prefix+"{0}"+currency_suffix },

//min:0,

//max:1000

},

legend: { position: "bottom" },

tooltip: { visible: true, format: "0" },

Style MVC DropDownListFor Helper to look like Kendo ComboBox

Hi,

I've browsed through the Kendo Styling documentation and found many simple ways to style my regular, hum-drum forms. However, I was wondering if there is a way to apply the ComboBox styles to MVC Helpers like DropDownListFor() and so on? I use MVC Helpers on a lot of my forms and would like to be able to standardize my Text and Dropdown lists to look the same.

I've tried applying the Kendo classes to my DropDownList's directly like this:

@Html.DropDownListFor(model => model.AccountTypeID, new SelectList((System.Collections.IEnumerable)ViewBag.AccountTypesDD, "Key", "Value"),

new { @class = "k-combobox" })

I've attempted to attach classes like "k-combobox, k-dropdown-wrap ect." but nothing styles the DropDownList to mimic the Style of a Kendo ComboBox.

I understand that this is probably because most of the Kendo Styles require layered <span/> tags to apply properly, but was wondering if there is an out-of-the-box way to apply them to MVC Helpers?

Thanks
Landon

Rails deeply nested routes creates a bug in tabstrip

I am developing a test app to try out kendo ui mobile.
The app has 3 main models which are present in the url : Organization, Shop, Category
Everything seems to be alright when I visit appdomain.com/categories or appdomain.com/organizations or even appdoman/organizations/1.
(Although the Home tabstrip button gets activated when I go to appdoman/organizations/1 but it still takes me back to the apps homepage if I click on it. )
The problem comes when I go deeper. Like appdomain.com/organization/1/category/2/shops or appdomain.com/organization/1/category/2/shops/1
When I visit those, TabStrip thinks from that point on that they are the homepage, the root url and messes up my whole nav structure.

What is the proper way to use rails nested routes with Kendo UI mobile so they won't effect the tabstrip nav in a negative way?

UPDATE
It seems that I had to remove the rails route helpers, and construct the urls differently.
So instead of:

<a href="<%= organizations_categories_shops_path(@category) %>">

I use:

<a href="/#/organizations/<%= @organization.id %>/categories/<%= category.id %>/shops">

You surely notice that I had to append /#/ manually at the beginning of these deeply nested urls to make it work. Still need to find out why, and where it is needed exactly.

Display value in grid column based on conditional

I have a hierarchy Grid. The child grid has complex values used to define the columns. I need to do a conditional when defining what to display in the "Value" column. "Value" is of type NotificationEventConditionValueViewModel, which is defined as:

public class NotificationEventConditionValueViewModel
{
public string ValueString { get; set; }
public System.DateTime ValueDate { get; set; }
public bool ValueBoolean { get; set; }
}

In my child grid I am trying to do a conditional based on the type of Value, something like the following:

columns.Bound(e => e.Value).Title("Value").ClientTemplate("\\#if(NotificationEventConditionField.FieldType.Id == 5){\\#=Value.ValueBoolean\\#}else{\\#=Value.ValueString\\#}\\#").Width(80).HeaderHtmlAttributes(new { style = "font-weight: bold;text-decoration: underline;" });

The
"\\#if(NotificationEventConditionField.FieldType.Id == 5) evaluates fine, but the
{\\#=Value.ValueBoolean\\#} does not show the value I want, instead it show the string: #=Value.ValueBoolean.

Can you please help me to determine what I am doing wrong in the syntax. I am attaching some files. In the COnfigure.cshtml look for Grid "UDEGrid_#=Id#" which is the child grid, and Grid "notificationGridUDE" which is the parent grid. A am also attaching the view models.
Thank yoy very much in advance.
