New item not returned by read() using Internet Explorer

I've noticed that while adding an item to the data source then calling sync() creates the item and read() successfully returns the expected rows in Chrome and Firefox, this doesn't appear to be the case in Internet Explorer. I can see the POST is successful and returns the new item via JSON. The item appears in the grid briefly, until read() is called. The GET caused by the read() method doesn't include the newly added item in the response. When I refresh the page, the new item is there.

I originally had the same problem as noted in this thread, but I've since set cache to false in the read function but still have the issue of new items not appearing in the results only when using IE.

Underscore breaks JSON data

I created a remote data source with underscores in the fields and the underscore character seems to be breaking the data source. Copied the data as a static JSON file and removed the underscore and it proved the issue.

Tips anyone on how to get Kendo to play nice with my data?

Don't care for query string...

I'm trying to create an autocomplete box. My web service uses MS Web API and I'd prefer to pass the value of autocomplete input field to the URL like this:
.../getProducts/sku=VALUE FROM FIELD

How would I go about this? If not, is one able to form a proper query string that won't need additional parsing to get a the value out? I've noticed the query string does not contain traditonal key/values.

I've also noticed the query string is chock full of crap despite me not specify paging, filtering, etc. I will be handling all this on the server and don't need to specify these items. Is it possible to remove this too?

Editing in grid using JSON web service

Hi,

I am trying to implement grid editing. Grid is using JSON web service as data source. Getting data works great, but when I try to save changes I get an error "The incoming message has an unexpected message format 'Raw'. The expected message formats for the operation are 'Xml'; 'Json'. "

var dataSource = new kendo.data.DataSource({

severFiltering: false,

serverPaging: true,

pageSize: 15,

batch: false,

transport: {

read: {

url: crudServiceBaseUrl,

dataType: "json"

},

update: {

url: crudServiceBaseUrl,

type: 'PUT',

dataType: "json"

}

},

schema: {

data: "Data",

total: "Count",

model: {

id: "ID",

fields: {

ID: { editable: false, nullable: false },

Name: { type: "string" },

Unit: { type: "string" }

}

});

$("#grid").kendoGrid({

theme: "metro",

dataSource: dataSource,

scrollable: false,

pageable: true,

height: 400,

toolbar: ["save", "cancel"],

columns: ["ID", "Name", "Unit"],

editable: true

});

What should I do to enable updates using JSON web service?

Thanks,

Igor

Performing multiple data store filter requests

Hi,

We have a server side filtering component to our data store. When we issue multiple requests before the server can respond:

dataStore.filter({ user_id: 1 });

dataStore.filter({ user_id: 2 });

The "user_id = 1" request may end up coming after the second request, which means the displayed data is not what the user requested.

Is there a way that this can be fixed? It seems like we can only listen to onChange events in the dataSource, which unfortunately don't tell us which request this response data is for. Thanks!

Sync method not called on DataSource

I have a very basic ASP.NET MVC app that has a kendoGrid and DataSource defined on a page. The read method works fine and populates the grid as expected, but I'm having issues with the create method. I've set the datasource's schema model to a model I defined and I've inspected and confirmed the model shows the new item after calling the add method on the datasource. Additionally, the new item also appears in the grid. For some reason, though, it seems when I call sync() the MVC controller method isn't called. Then when read() is called on the datasource the new item is cleared since it wasn't persisted.

Hopefully I've just missed something very simple, but I'm pretty confused why the create method doesn't seem to be called when the datasource is synced.

Any ideas?

dataSource observability documentation semantics

It would be helpful to differentiate between one time (once only), one way (source to target) and two way (bi-directional) concepts when discussing observability.
