It fully supports CRUD Create, Read, Update, Destroy data operations and provides both client-side and server-side support for sorting, paging, filtering, grouping, and aggregates.
When you bind the DataSource to remote data, the component requires information about the web service URLs, the request type, the response data type, and the structure schema of the response if it is more complex than a plain array of objects.
You can also provide custom parameters which will be submitted during the data request. All data operations have to occur either on the server or on the client. While you can still determine that part of the data operations will be held on the server and part on the client, using the DataSource in its mixed data-operation mode leads to undesired side effects. For example, if serverPaging is enabled and serverFiltering is disabled, the DataSource will filter only the data from the current page and the user will see less results than expected.
In other scenarios, the DataSource might make more requests than necessary for the data operations to execute. Kendo UI widgets support data binding and use the DataSource component as a binding source for both local and remote data.
The following example demonstrates how to create a DataSource inline with the other Kendo UI widget settings. The following example demonstrates how to create a shared DataSource and allow multiple Kendo UI widgets to bind to the same data collection. Using a shared DataSource decreases the data requests, improves the performance, and provides automatic synchronized refreshing of all the bound widgets when the data changes. All Rights Reserved.

There have been a few changes to the markup, as you can see from the output. I've also adjusted the table slightly and added a "remove" button below it, to allow us to remove items that are already done.
Handling the addition of a "to do" item is done with a jQuery selector and a DOM "click" event for the "add" button. When we receive that event, we read the "to do" description from the input box.
Then we build an object literal that contains all of the fields we need: an id, a "done" status and the description we entered. Adding a "to do" item to the DataSource is very simple, as you can see.
You only need to call the add method on the dataSource instance, and pass in the object to be added. To create the "to do" items with a unique ID, I've added a "currentId" variable to this code. This is used as a simple counter to give me an incremental ID to attach to new "to do" items, which is used to determine the item that is being marked as done see the previous post for more information on that when clicking a "done" checkbox.
The currentId variable increments prior to every use, ensuring that we have a unique ID for each item we add. I'm also clearing out the description input box after the item has been added and then re-focusing the browser that input box. This allows me to add a number of "to do" items faster as it reduces the number of clicks needed to create one and re-focus on the text input field.
Clearing the items that are already "done" takes a little more work than adding an item.A complete jQuery UI component library that allows to quickly build stunning and high-performance responsive web applications.

DropDownList in two different contexts, but must update one attribute [. Name "DisbursedTo" ]. It worked, except that each ddl widget required a unique '. Name', so my updates to the model attribute were off. Using one ddl, I'm trying to dynamically change the ddl properties. By default I load the ddl with 'Locations' data this works fine.
I'm getting the following error on the 'ddl. The provided code suggests that you are initializing new DropDownList widgets from the same HTML element every time, and also that new DataSources are created every time.
You can create the two different DataSources outside of the functions, and then in the functions bodies use the DropDownList setDataSource method to switch between the two dataSources, and the setOptions method to change the other options like dataTextField and dataValueField, e.

A bar chart may display the budget for each task. My problem is that the DataSource seems not to fit this requirement, because a grouping and aggregation for the pie chart seems not to be possible. Is the DataSource designed to be shared among different modules? Posted 11 Sep Link to this post.
Indeed, it is possible to bind multiple widgets to a single DataSource instance. However, the DataSource component does not support multiple views. This means that once a grouping or sorting, or filtering are applied, the data will be shaped the same way for all of the bound widgets.
