Cell Configuration

This guide details the various aspects and features of data grid cells, covering essential properties like the DOM element reference, editor types, and essential attributes, including read-only status and custom render functions. It further delves into methods for interacting with and tailoring cell functionality to meet specific needs.

Documentation Overview

Methods for Cell Interaction

This section outlines methods to facilitate interaction with cells and their attributes within the data grid.

Method Description
getCell Retrieves the DOM element of a cell by its grid reference (e.g., A1, B3).
getCell(cellName: String) => Object
getCellFromCoords Obtains the DOM element of a cell using its grid coordinates, with (0,0) corresponding to A1.
getCellFromCoords(x: Number, y: Number) => Object
isAttached Checks if a cell element is currently part of the DOM tree.
isAttached(x: Number, y: Number) => Boolean
getProperty Fetches the properties of a specified cell.
getProperty(column: Number, row: Number) => Object
setProperty Sets or updates properties for a given cell.
setProperty(column: Number, row: Number, properties: Object) => void

Internal methods

Method Description
getCells Get the configuration of a cell including type, masks and other attributes.
getCells(cellName: String) => Object

Alternative: getProperty()
setCells Set the configuration for a cell or multiple cells without events or history or DOM updates.
setCells(cellNames: String|Object, attributes?: Object) => void

Alternative: setProperty()
updateCell Update the cell value without events or history.
updateCell(x: Number, y: Number, value: String, force: Boolean) => []

Alternative: setValue()

Events

Property Description
oncreatecell This method will be called when a cell is created.
oncreatecell(worksheet: Object, cell: DOMElement, x: Number, y: Number, value: Value) => void
