Updating grid data

Actual editing, including various built-in options for CRUD operations will be introduced in Q2. With regard to updating the record, note that set At does not insert a new item but replaces the old one, therefore you can use it for updating.

control can display a user interface (UI) to enable users to edit the contents of individual rows.

Hello Chris, Depending on your requirements, you have two options.

The first one is to simply reassign the data property of the Rad Grid data Source.

Typically, an editable grid contains a column with a button or link in it that users can click to put the row into edit mode.

(By default, the button caption is "Edit.") When users save a change, the dictionary contains the names and values of fields that uniquely identify the record to update or delete, and always contains the original values of the key fields.

Method 3 - Delta Row Data The final method is using the row data method above but having the property .

When delta Row Data Mode is on, the grid will compare the new row data with the current row data and create a transaction object for you.

The grid will then be aware of the change and also update the relevant parts of the UI.

If you are using an immutable data store, as is usual in a React application, then you will be interested in the section below Bulk Method 3 - Delta Row Data.

Microsoft is conducting an online survey to understand your opinion of the Msdn Web site.

If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site.

You can also use this technique in a non-Redux or immutable store based application (which is the case in the examples on this page).
