If you fetch data from the server, some operations with data can be executed remotely, while others - locally.If you perform basic operations (sorting, filtering, and paging) remotely and advanced operations (grouping and summary calculation) locally, certain user actions will force Data Grid to query the server for data repeatedly despite caching being enabled.In the following code, the customize Export Data function replaces empty values with the import React from 'react'; import 'devextreme/dist/css/dx.common.css'; import 'devextreme/dist/css/dx.light.css'; import Custom Store from 'devextreme/data/custom_store'; import from 'devextreme-aspnet-data-nojquery'; import Data Grid from 'devextreme-react/data-grid'; const service Url = "https://url/to/my/service"; const store = create Store(); class App extends React.
One of the other capabilities allows you to control the sorting of column values using the allow Sorting and sort Order options, apply a filter to grid records using the allow Filtering and filter Operations options, and group grid records using the allow Grouping and group Index options.
For this, set the column Fixing.enabled option to true.
When you enable column fixing, command columns become fixed automatically.
The Row Updating event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
