Using jquery to add to model

Not sure this is the right forum for this but here goes. I have a mobile app that gets an image via the camera. It puts the contents of the image into the variable 'imageData' I then use jquery:

$('#smallImage').attr('src', "data:image/jpeg;base64," + imageData);

into the image:

<img id="smallImage" width="100%" data-bind="attr: { src: Robot.Picture }">

that works fine as far as display goes. It does not however add it to "Robot"

I am using jaydata to save the data to a local database and the model has a lot of fields (all text inputs) and they all data-bind fine.

Any ideas?

Column Series - how to set CategoryMemberName using MVC helper

Hi
I'm trying to set the CategoryMemberName in MVC using the chart builder - ChartSeriesFactory. I see in the API docs there is an overload of column that is supposed to take 4 string arguments, yet I am getting compilation errors that no overload of column takes 4 strings. How can I set the CategoryField on my series to a string using MVC helper?

from the api docs

Column(System.String,System.String,System.String,System.String)
Defines bound bar series.
Parameters
valueMemberName System.String The name of the value member.
colorMemberName System.String The name of the color member.
categoryMemberName System.String The name of the category member.
noteTextMemberName System.String The name of the note text memberFrom <http://docs.kendoui.com/api/wrappers/aspnet-mvc/Kendo.Mvc.UI.Fluent/ChartSeriesFactory>

Custom Editor, NOT CHANGE THE MODEL

My Exemple: http://jsfiddle.net/rhvieira/FkP8z/

To show the error you need follow steps.
1- Click in Edit button
2 - click in the pencil in the first column
3 - type a value into html control and close the window.
4 - click in update button

Now occurs the error, in this step I try update the model, but when i did it the visual has been changed but the internal data is not marked as changed, then when
I send all informations to the server the record is not updated.

When I do the same steps in new record all works are done or when change the first and other column and save this work too.

Best Regards,
Vieira

Issue in display a date from JSON data, need to format inside kendo template with dynamic values

I am using dataSource and kendo template to populate a list of details from a api. Below code explain the view and viewmodel to display the data.
View:

<div data-role="view" id="myProjectView" data-title="Products List" data-init="myProjectListViewTemplatesInit">

<header data-role="header">

<div data-role="navbar">

<span data-role="view-title"></span>

<a data-align="right" data-role="button" class="nav-button" href="#index">Index</a>

</div>

</header>

<ul id="myProjectCustomListView"></ul>

</div>

<script id="myProjectCustomListViewTemplate" type="text/x-kendo-template">

<h3 class="item-title">Project Name: ${ProjectName}</h3>

<p class="item-info">Created Date: ${CreateDate}</p>

</script>

<script src="scripts/jquery.min.js"></script>

<script src="scripts/kendo.mobile.min.js"></script>

<script src="scripts/viewModel/myProjectsViewModel.js"></script>

<script>var app = new kendo.mobile.Application(document.body);</script>

viewModel - myProjectsViewModel.js

function myProjectListViewTemplatesInit(){

var dataSource = new kendo.data.DataSource({

transport: {

read: {

url: "http://127.0.0.1/api/getProjectList",

dataType: "json",

}

},

});

$("#myProjectCustomListView").kendoMobileListView({

dataSource: dataSource,

template: $("#myProjectCustomListViewTemplate").html(),

});

};

The above api will return JSON data like below

[{"ProjectId":2,"ProjectCode":"TestProject","ProjectName":"TestProject","Description":"","CreateDate":"2013-09-13T00:00:00","Owner":"TestProject","StartDate":"2013-09-13T00:00:00","EndDate":"2013-09-13T00:00:00","StatusId":4,"IsActive":true,"ERPCompany":"","TemplateId":0,"DocumentTemplateID":0,"DocMetadataID":null,"IsDeleted":"","ERPCurrency":"$","ProjectMode":"L","DocumentListID":"","RowNum":3,"pagecount-1":null},{"ProjectId":1,"ProjectCode":"TemplateProject","ProjectName":"TemplateProject","Description":"","CreateDate":"2013-09-13T00:00:00","Owner":"Aurigo","StartDate":"2013-09-13T00:00:00","EndDate":"2013-09-13T00:00:00","StatusId":4,"IsActive":true,"ERPCompany":"","TemplateId":0,"DocumentTemplateID":0,"DocMetadataID":null,"IsDeleted":"","ERPCurrency":"$","ProjectMode":"L","DocumentListID":"","RowNum":4,"pagecount-1":null}]

I want to format the date column(CreateDate: 2013-09-13T00:00:00) like 13/09/2013. Help me in this.

Changing Tab's Content

Hello,
i'm using a TabStrip in which every Tab contains an iframe with a web page with JSON data loaded via AJAX. Inside of the frame i do include plenty of JS and CSS files.

I would like to dinamically change the content of the tab, but i would like to know if it's safe to simply use the remove() call on the Tab or if i need some special actions to make sure to clean everything?

Thanks in advantage.

Server Error when displaying charts

Hello,

Have done an install of the kendoui.aspnetmvc.2013.2.918.trial.msi package.

Getting a YSOD on any chart with a MajorGridLines(lines => lines.Visible(false)) in it, running the supplied demo app causes issue also, all other dataviz control work fine.

Have reinstalled and also restarted machine, no luck.

Running Windows 8.0, VS 2012.

Is this an issue with the trial distribution?

Many Thanks

Show loading image on chart before load

I'm trying to show the "kendo.ui.progress" or just an image over the div before the chart loads the data. I have up too 10 charts on my dashboard at one time so there is a lag between each of them loading and it looks werid with just a blank graph. I'm getting the data from a webservice and I've tried adding an loading-image class to the charts div but nothing I have tried has worked. Can anyone help me out.

this is an example of one of my charts:

var dsOrderHis = null;

$(document).ready(function()

{

args.startDate = startDate;

args.endDate = endDate;

args.filterBy = filterBy;

args.userIds = userIds;

dsOrderHis = new kendo.data.DataSource(

{ transport: { read: { cache: false,

url: appUrl + "/Services/ArgosyDashBoardService.svc/orderHistory",

dataType: "json", contentType: "application/json; charset=utf-8", type: "POST" },

parameterMap: function(options, operation) { return JSON.stringify(args) } },

schema: { data: "OrderHistoryResult" },

change: function() {

var dataCount = $("#LoadOrderHistoryDiv").data("kendoChart").dataSource.view().length;

if (dataCount <= 0) { setTimeout("LoadOrderHistoryHideSvg();", 400) }

else

$("#LoadOrderHistoryDiv svg").each(function() { $(this).fadeIn() });

setTimeout("LoadOrderHistoryAddIcon();", 100) } }

});

$('#LoadOrderHistoryDiv').kendoChart({

theme: currentTheme,

title: { text: 'Order: History' },

dataSource: dsOrderHis, legend: { position: "bottom" },

series: [{ type: "line", field: "YAxis"}],

categoryAxis: { field: "XAxisLabel", labels: { rotation: 42} },

tooltip: { visible: true, template: " #= value # orders placed in #= category # .", padding: 9 },

legend: { visible: false} })

});

//used for data changes

function LoadOrderHistory()

{

var chart = $("#LoadOrderHistoryDiv").data("kendoChart");

args.startDate = startDate;

args.endDate = endDate;

args.filterBy = filterBy;

args.userIds = userIds;

kendo.ui.progress($("#LoadOrderHistoryDiv"), true);

chart.dataSource.read()

}
