FieldColumn | API Reference | ArcGIS Maps SDK for JavaScript 4.33

The FieldColumn class works with the FeatureTable and provides the underlying logic for column behavior.

This class should be used for observing potential changes. Any configuration and changes to the field columns should be done handled via the TableTemplate and the FieldColumnTemplate class.

Property Details

alias Property alias String |null |undefinedreadonly

The display name for the field.

autoWidth Inherited Property autoWidth Boolean Inherited from Column

Indicates if the column width will automatically adjust to account for large content. The column ignores the current width property when autoWidth is true.

Default Value:false

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

The name of the class. The declared class name is formatted as esri.folder.className.

defaultValue Property defaultValue Number |String |null |undefinedreadonly

The default value set for the field.

description Inherited Property description String |null |undefined Inherited from Column

Contains information describing the purpose of each column.

direction Inherited Property direction String |null |undefined Inherited from Column

Controls the sort order of the column. This property will only be honored on one column in the FeatureTable widget. If direction is specified on more than one column in the same FeatureTable, it will only be honored on the column with the highest index.

This is used in combination with the initialSortPriority and FeatureTable.multiSortEnabled properties to set sorting functionality for multiple columns.

Possible Value	Description
asc	Sorts the column in ascending order.
desc	Sorts the column in descending order.
null	No sort is applied to the column.

Possible Values:"asc" |"desc"

editable Property editable Boolean

Indicates whether the field is editable. Editing permissions can be broken down with the following levels of priority:

Field - This is derived from the FeatureLayer or SceneLayer. It takes what is set in the Field.editable property. This must always be true for editing to be enabled. This can be overridden using a field column template.
Template - The editable permissions on a field can be configured by setting the editable property of the FieldColumnTemplate.
FeatureTable - The editingEnabled property must be set on the table in order for any type of editing to be enabled.

For example, if table editing is disabled in the widget, i.e. enableEditing is not set, it is still possible to enable editing for a specific column by setting the editable property. Vice versa is also true, if table editing is enabled, a field template can be used to disable editing for a specific column.

Ultimately, if the service's field is not editable, it is not possible to override its permissions using one of the options above.

FieldColumnTemplate.editable

effectiveDescription Property effectiveDescription String |null |undefinedreadonly Since: ArcGIS Maps SDK for JavaScript 4.31 FieldColumn since 4.16, effectiveDescription added at 4.31.

The sanitized description, describing the purpose of each column. This takes into account the optional values of both the columns's template description and the value of the field's description. The template description takes precedence over the field's description as to allow for customizing the column's description.

See also

effectiveLabel Inherited Property effectiveLabel String Inherited from Column

The sanitized label string safe for display in the header cell. Defaults to using fieldName if a label is not defined on the column.

field Property field Fieldautocast

The Field associated with this column.

The unique field name as defined by the data source.

flexGrow Inherited Property flexGrow Number Inherited from Column

Controls the flex-grow property for the column. When set to 0, cell width is fixed.

Default Value:1

formatFunction Property formatFunction FieldValueFormatFunction |null |undefined

Custom function for rendering cell content that is called when the column is rendered in the table. The function should return the formatted content to display within a table's cell. This can be a string, number, an HTML element, or equivalent node type (e.g. a Calcite component). If the content is an HTML element, it is appended to the root element. If the content is a string or number, it is set as the innerHTML of the root element. If the content is null, the root element is cleared. If the content is undefined, the root element is not modified. This property is useful when you want to customize the cell content. For example, you can use this property to create a custom cell renderer that displays a progress bar in the cell. The progress bar can be used to show the progress of a task.

Indicates if the the column is frozen in place at the beginning of the table. Column must be first in the FeatureTable's column's, or next to other frozen columns.

Default Value:false

const handle = reactiveUtils.when(
  () => !view.updating,
  () => {
    wkidSelect.disabled = false;
  },
  { once: true }
);

this.addHandles(handle);

// Destroy the object
this.destroy();

Parameters

handleOrHandles WatchHandle|WatchHandle []

Handles marked for removal once the object is destroyed.

groupKey *

Returns

Type	Description
Boolean	Returns `true` if a named group of handles exist.

Example

// Remove a named group of handles if they exist.
if (obj.hasHandles("watch-view-updates")) {
  obj.removeHandles("watch-view-updates");
}

openMenu Inherited Method openMenu() Inherited from Column

Convenience method for opening the column menu. This has no effect if the menu is not visible or has no menu items. It follows the direction pattern of ascending, to descending, then no sort order.

Type Definitions

FieldValueFormatFunction Type Definition FieldValueFormatFunction(params){String |Number |HTMLElement |null |undefined}

Custom function for rendering cell content. Accepts a string, number, an HTML element or equivalent node type (e.g. a Calcite component).

Parameters

Specification

params Object

An object containing information about the associated row and feature.

Specification

attachments AttachmentInfo []

(Since 4.31) A reference to attachments for the associated feature.

column Column

A reference to this specific Column.

feature Graphic

A reference to the feature represented by the associated row.

index Number

Index of the associated row being rendered.

relatedRecords RelatedRecordInfo []

(Since 4.31) A reference to related records for the associated feature.

virtualIndex Number

(Since 4.31) Virtual index of the associated row being rendered. Unlike index, a row's virtualIndex changes as the table scrolls. The first row in the DOM has a virtualIndex of 0. As rows are added/removed from the DOM, the virtual index adjusts before it renders. This can help with performance when rendering large datasets.

value String|Number|null|undefined

Current projected value of the cell.

field Field|null|undefined

The field associated with the column.

Returns

Type	Description
String \| Number \| HTMLElement \| null \| undefined	Formatted content to be displayed in the cell.
