GroupColumn | API Reference | ArcGIS Maps SDK for JavaScript 4.30

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

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

Property Details

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

columns Property columns Column[]readonly

An array of columns to display as grouped which represent an ordered list of FeatureTable columns.

declaredClass Inherited Property declaredClass Stringreadonly Inherited from Accessor

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

direction Inherited Property direction String |null 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"

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.

fieldName Inherited Property fieldName Stringreadonly Inherited from 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 Inherited Property formatFunction FormatFunctionreadonly Inherited from Column

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.

Example

// The following example demonstrates how to use the formatFunction 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.
column.formatFunction = (column, feature, index, value )=> {
  const progress = document.createElement("progress");
  progress.max = 100;
  progress.value = value;
  return progress;
};

frozen Inherited Property frozen Booleanreadonly Inherited from Column

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

frozenToEnd Inherited Property frozenToEnd Booleanreadonly Inherited from Column

Indicates if the column is frozen in place at the end of the table. Column must be last in the FeatureTable's column's, or next to other columns with frozenToEnd set to true.

Default Value:false

icon Inherited Property icon String Inherited from Column

The string value indicating the icon displayed in the header cell of the column.

Aligns the columns cell content horizontally.

Possible Values:"start" |"center" |"end"

Default Value:"start"

textWrap Inherited Property textWrap Boolean Inherited from Column

Indicates cell content should be wrapped and displayed on multiple lines within the cell. Warning: this causes rows to expand when tall content is visible in the viewport. Scrolling tall cells into the viewport may cause the table to visually jump depending on the height of the expanding rows.

Default Value:false

timeZone Inherited Property timeZone Stringreadonly Inherited from Column

The storage IANA time zone of the column.

See also

visibleElements Inherited Property visibleElements VisibleElements Inherited from Column

The visible elements of the column's associated FeatureTable.

width Inherited Property width Number |String Inherited from Column

Width of the column in pixels. If providing value as a string, the string must include "px" suffix. This value is only honored when there are enough columns to fill the viewport, or flexGrow has been set to 0.

Default Value:200

Method Details

addHandles Inherited Method addHandles(handleOrHandles, groupKey) Inherited from Accessor Since: ArcGIS Maps SDK for JavaScript 4.25 Accessor since 4.0, addHandles added at 4.25.

Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.

// Manually manage handles
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 *

optional

Key identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.

closeMenu Inherited Method closeMenu() Inherited from Column

Convenience method for closing the column menu.

A group key.

Returns

Object

Returns an event handler with a remove() method that should be called to stop listening for the event(s).
