I modified the “Detail Grid” which can be found here:
To use this example with a couple of Java actions instead of the RSS feed. However, I'm having problems filtering the detail data because of the fact that I’m omitting the type: "odata" in my HTML.
So, the original Employees data source looked like this:
The original Orders data source looked like this:
The modified Employees data source looks like this:
The modified Orders data source looks like this:
You’ll notice that I had to make the change to: dataType: "json", in order for this example to work.
Also, if you look inside “kendo.all.js”, you’ll notice that “filter: { }” will only work with “odata”.
Now, any ideas how I can get my sample to work with filtering?

Hello,
Filters only works with odata since filter is populated via kendo.data.odata.js .
You will see on source file kendo.data.odata.js that odata Datasource will map your filter request to an string value passed to service.
It also add top, skip & order parameters. In addition, and due to odata specifications, it will add a callback() function to fullfill jsonp needs.
I do not known how your services GetEmployee & GetOrder works.
Does they implements a OData service provider or a JSON/JSONP answer based on some parameters on url ?
Does they return a table like this :
or does they return a direct table of objects ? :
I see 3 possibles solutions :
1. your services implements OData specification and you do not need to worry about json, use odata will feet your needs
2. your services implements a function returning a JSON table, and you have to use "data" to pass your parameters to your services and take care of filtering, sorting, top & skip
http://demos.kendoui.com/web/datasource/remote-data.html
3. advanced : Kendo OData format is only there to wrap filters, top, skip & sort and returns a total & some results to bind on table (a subset of results). If your needs doesn't feet odata specification, you can do your own implementation based on kendo.data.odata.js
If you can post an example of what return your service & also witch parameters your services understand we could made a sample.

Hello,
The demo is using a WCF DataService. A sample project(grid-odata-crud) using a Grid with OData DataSource is available in our GitHub repository on this page.
