Selector
kendo-treelist
Export Name
Accessible in templates as #kendoTreeListInstance="kendoTreeList"
Inputs
aria-label string
An optional accessible description of the component.
autoSize boolean
Indicates whether the TreeList columns will be resized during initialization so that
they fit their headers and row content. Defaults to false.
Columns with autoSize set to false are excluded.
To dynamically update the column width to match the new content,
refer to this example.
columnMenu boolean | ColumnMenuSettings (default: false)
Specifies if the column menu of the columns will be displayed (see example).
filter CompositeFilterDescriptor
The descriptor by which the data will be filtered (see examples).
filterable FilterableSettings
Enables the filtering of the TreeList columns that have their field option set.
height number
Defines the height (in pixels) that is used when the scrollable option of the TreeList is set.
To set the height of the TreeList, you can also use style.height. The style.height
option supports units such as px, %, em, rem, and others.
hideHeader boolean
Specifies if the header of the treelist will be hidden. The header is visible by default.
The header includes column headers and the filter row.
loading boolean (default: false)
Specifies if the loading indicator of the TreeList will be displayed (see example).
navigable boolean
If set to true, the user can use dedicated shortcuts to interact with the TreeList.
By default, navigation is disabled and the TreeList content is accessible in the normal tab sequence.
pageSize number (default: 10)
Defines the page size used by the TreeList when paging is enabled.
pageable PagerSettings | boolean
Configures the pager of the TreeList (see example).
The available options are:
-
buttonCount: Number—Sets the maximum numeric buttons count before the buttons are collapsed. -
info: Boolean—Toggles the information about the current page and the total number of records. -
type: PagerType—Accepts thenumeric(buttons with numbers) andinput(input for typing the page number) values. -
pageSizes: BooleanorArray<number>—Shows a menu for selecting the page size. -
previousNext: Boolean—Toggles the Previous and Next buttons.
reorderable boolean (default: false)
If set to true, the user can reorder columns by dragging their header cells
(see example).
resizable boolean (default: false)
If set to true, the user can resize columns by dragging the edges (resize handles) of their header cells
(see example).
rowHeight number
Defines the row height that is used when the scrollable option of the TreeList is set to virtual.
Required by the virtual scrolling functionality.
scrollable ScrollMode
Defines the scroll mode used by the TreeList.
The available options are:
-
none—Renders no scrollbar. -
scrollable—The default scroll mode. It requires the setting of theheightoption.
sortable SortSettings
Enables the sorting of the TreeList columns that have their field option set.
trackBy TrackByFunction<TreeListItem>
A function that defines how to track changes for the data rows.
By default, the TreeList tracks changes by the index of the data item.
Edited rows are tracked by reference.
In some cases, you might need to override the default behavior,
for example, when you implement editing with immutable data items.
The following example demonstrates how to track items only by index.
import { Component } from '@angular/core';
import { TreeListItem } from '@progress/kendo-angular-treelist';
@Component({
selector: 'my-app',
template: `
<kendo-treelist [data]="treelistData" [trackBy]="trackBy">
</kendo-treelist>
`
})
class AppComponent {
public treelistData: any[] = products;
public trackBy(index: number, item: TreeListItem): any {
console.log(item);
return index;
}
}
const products = [{
"ProductID": 1,
"ProductName": "Chai",
"UnitPrice": 18.0000,
"Discontinued": true
}, {
"ProductID": 2,
"ProductName": "Chang",
"UnitPrice": 19.0000,
"Discontinued": false
}
];virtualColumns boolean
If set to true, the treelist will render only the columns in the current viewport.
data Array<any> | TreeListDataResult | Observable<any>
Sets the data of the TreeList. If an array is provided, the TreeList automatically gets the total count
(more information and example).
fetchChildren (node: any) => Observable<any[]> | any[]
Gets or sets the callback function that retrieves the child nodes for a particular node.
hasChildren (node: any) => boolean
Gets or sets the callback function that indicates if a particular node has child nodes.
idField string (default: "id")
The name of the field which contains the unique identifier of the node.
isExpanded (node: any) => boolean
Sets the callback function that indicates if a particular item is expanded.
isSelected IsSelectedFn
Provides a callback that determines if the given row / cell is selected.
rowClass RowClassFn
Defines a function that is executed for every data row in the component.
import { Component, ViewEncapsulation } from '@angular/core';
import { RowClassArgs } from '@progress/kendo-angular-treelist';
@Component({
selector: 'my-app',

Methods
addRow
Creates a new row editor (see example).
Parameters
group any
The FormGroup that describes
the edit form. If called with a data item, it will build the FormGroup from the data item fields.
parent? any
autoFitColumn
Applies the minimum possible width for the specified column,
so that the whole text fits without wrapping. This method expects the TreeList
to be resizable (set resizable to true).
Makes sense to execute this method only
after the TreeList is already populated with data.

];Parameters
columns Array<ColumnBase> | QueryList<ColumnBase>
cancelCell
Closes the current cell in edit mode.
closeCell
Closes the current cell in edit mode and fires
the cellClose event.
Returns
boolean Indicates whether the edited cell was closed.
A false value indicates that the
cellClose event was prevented.
closeRow
Closes the editor for a given row (see example).
Parameters
item any
isNew boolean
collapse
Collapses the row for the specified dataItem.
Parameters
dataItem any
drawPDF
Exports the TreeList element to a Drawing Group by using the kendo-treelist-pdf component options.
(see example).
Returns
Promise<any> - A promise that will be resolved with the Drawing Group.
editCell
Puts the cell that is specified by the table row and column in edit mode.
Parameters
dataItem any
column number | string | any
The leaf column index, or the field name or the column instance that should be edited.
group? any
The FormGroup
that describes the edit form.
editRow
Switches the specified table row in the edit mode (see example).
Parameters
item any
group? any
The FormGroup
that describes the edit form.
options? {[skipFocus: string]: boolean}
Additional options. Use skipFocus to determine if the row's edit element should be focused. Defaults to false.
expand
Expands the row for the specified dataItem.
Parameters
dataItem any
focus
Focuses the last active or the first cell of the TreeList.
Returns
NavigationCell The focused cell.
focusCell
Focuses the cell with the specified row and column index.
The row index is based on the logical structure of the TreeList and does not correspond to the data item index:
- Header rows are included, starting at index 0.
- The row indexing is absolute and does not change with paging.
If the TreeList is configured for scrolling, including virtual scrolling, the scroll position will be updated.
If the row is not present on the current page, the method will have no effect.
Parameters
rowIndex number
The logical row index to focus. The top header row has an index 0.
colIndex number
The column index to focus.
Returns
NavigationCell The focused cell.
focusNextCell
Focuses the next cell, optionally wrapping to the next row.
Parameters
wrap boolean
A Boolean value which indicates if the focus will move to the next row. Defaults to true.
Returns
NavigationCell The focused cell. If the focus is already on the last cell, returns null.
focusPrevCell
Focuses the previous cell. Optionally wraps to the previous row.
Parameters
wrap boolean
A Boolean value which indicates if the focus will move to the next row. Defaults to true.
Returns
NavigationCell The focused cell. If the focus is already on the first cell, returns null.
isEditing
Returns a flag which indicates if a row or a cell is currently edited.
Returns
boolean A flag which indicates if a row or a cell is currently edited.
isEditingCell
Returns a flag which indicates if a cell is currently edited.
Returns
boolean A flag which indicates if a cell is currently being edited.
reload
Clears the already loaded children for the dataItem so that the TreeList will fetch them again the next time it is rendered.
Parameters
dataItem any
reloadChildren? boolean
reorderColumn
Changes the position of the specified column.
The reordering of columns operates only on the level
