See argument "data" in "data : function(data){ " by Firebug,
data is string object.
When first loading, the data is json object.
Server responses same text data, first loading and update's post method.
dataSource: { transport: { read: { url:"getList.asp", dataType: "json" , data : { 'entity': 'XXX' } }, update: { url: "update.asp", type : 'POST', data : { entity : 'XXX' } } }, schema : { data : function(data){ var new_data = []; /* make data for grid from remote data */ return new_data; }, model: { id: "id", fields: { amp_name: { editable: false }, termStart: { editable: false }, volume: { type: "number", validation: { max : { value : 1000, message : "XXX"} } } } },

I have set my culture to use EN-GB format
I have a change event that updates a hidden field. Visually I can see the calendar selecting the right format however the hidden field is always using the US format.
Do I need to something different to get this to work or is there a bug with the control?
$("#datePicker").kendoDatePicker( { change: function () { $("#CampaignModel_RequiredSendDate").val(kendo.toString(this.value(), 'd')); } });I have a change event that updates a hidden field.

Does the Grid widget store an entire cell value, with the option to show a certain number of decimal points?
In other words, if a value in the database was 53.858708069844, would that entire value be in memory, and then I can choose to display it as 53.86 or 53.9 or even 54? I ask this for exporting purposes; I would need to export the entire values to a spreadsheet, even though the website itself would only show the number of decimal points the user selected. I would imagine it pretty easy to store the actual value as an attribute in the <td> tag.

I am attempting to use the kendoui window in an mvc3 project I am working on.
Scenario is I am wanting to use the window as nice way to insert data and validate the data clientside before sending back to the server.
The window contains it's own form and I am trying to post the data back to the server via ajax.
The form isn't anything special standard asp.net mvc stuff
I have tried added reference to the validation scripts
However......everytime I try submit the form validation is always telling me its valid even tho I know its not.
Is there something special I need to do so I can enable clientside validation in the window?

I have a chart that is using a datasource which queries a web service based on a time range selected by the user. The web service is set to limit the results to a maximum of 800 values. In IE9 it is no problem and the request duration for a query takes 203ms with a content length of 100264. The same query in IE8 results in a a script error on the page "A script on this page is causing Internet Explorer to run slowly". Is there any guidance on datasource response size limitations with IE8?

Hi,
I am evaluating Kendo ui by building a prototype in work. I am running into an issue where I can't seem to reuse datasources in global scope. I was hoping to define my datasources once and instantiate 1 remote datasource for each data model the app needs. My content loads and unloads (via ajax) inside a div and widgets (mostly grids) are swapped in and out and bind to whatever datasources they need. I expected the instances of these widgets would be cleaned up as the content pane is being destroyed and re-created. It seems that even though the DOM elements are being removed the grid instances are remaining. So every time the same content pane is loaded in the same session, a new instance of the grid is created and never goes away. When the user visits the same content pane over and over he creates more and more invisible grid instances. I proved this by putting break points in the refresh function of the grid. Grids that are no longer visible are still listening for data updates and drawing on every datasource change event. These objects don't go away until I refresh the page or close it. It would seem that datasources hold references to the widget objects they are bound to and prevent them from getting picked up by the garbage collector (I tested several browsers all with the same results).
The only way I can seem to fix this is to take the datasources out of the global space. If I put the creation of the datasource in the content pages with the widgets then the datasources and widgets are cleaned up the next time the user loads the content pane. But the problem is now I have to rewrite the datasource signature for every content page that looks at the same data.
I guess my first question is: Is there some trick I'm missing for using global datasources? Is there some kind of resource flush that I didn't see in the documentation?
If not is there a best practice for sharing datasources with widgets that care created and destroyed on the same page? (single page application)
Thanks

Hello Kendo,
I was really excited about trying the Kendo mobile UI demos, but why do the demos display the virutal mobile device, even on my iPhone? Can I see how the mobile UI renders the controls natively on my iPhone without the virtual mobile device?
Thank you.

Hi,
I am playing with the grid to consume data from a webservice. The webservice accepts only json object. So I try the params "take=5&skip=0&page=1&pageSize=5" to convert to a json string with parameterMap, but this dosn't work. Are there any emxamples?
Cheers,
George

Hopefully this is a simple question. I have multiple places on my page which correspond to different items on the page for which a user can attach a file. I want to have one file upload element on the page and just be able to call it from other elements.
How do I call the click on the element? I don't see any information in your documentation telling me how to accomplish this.

Can you please give me some example code examples for customising the Filter pop up on a grid.
For example we would like to remove the 'Ends With' option from the first drop down and also is it possible remove the second part of filter argument e.g - remove the AND and second drop down on some of columns. Obviously some colums will be different.
