Export Name

Accessible in templates as #kendoGridInstance="kendoGrid"

Inputs

Name	Type	Default	Description
autoSize	`boolean`	`false`	Indicates whether the Grid columns will be resized during initialization so that they fit their headers and row content. Columns with `autoSize` set to `false` are excluded. To dynamically update the column width to match the new content, refer to this example.
cellSelected	`CellSelectedFn`		Defines a function that determines the selected state of a data cell. Returns an object with `selected` and `item` properties. The cell is marked as selected only if the `selected` property equals `true`. The function is executed for each data cell and may be called more than once as part of a change detection cycle. (see example)
columnMenu	`boolean \| ColumnMenuSettings`	`false`	Specifies if the column menu of the columns will be displayed (see example).
data	`any[] \| GridDataResult`		Sets the data of the Grid. If an array is provided, the Grid automatically gets the total count (more information and example).
detailRowHeight	`number`		Represent the actual height of each Grid detail row (`tr`) element in the DOM. Required by the virtual scrolling functionality. Set the `detailRowHeight` option to the exact pixels as the height of the detail Grid `tr` element appears in the DOM.
filter	`CompositeFilterDescriptor`		The descriptor by which the data will be filtered (see examples).
filterable	`FilterableSettings`	`false`	Enables the filtering of the Grid columns that have their `field` option set.
group	`GroupDescriptor[]`		The descriptors by which the data will be grouped (see example).
groupable	`boolean \| GroupableSettings`	`false`	If set to `true`, the user can group the Grid by dragging the column header cells (see example).
height	`number`		Defines the height (in pixels) that is used when the `scrollable` option of the Grid is set. To set the height of the Grid, you can also use `style.height`. The `style.height` option supports units such as `px`, `%`, `em`, `rem`, and others.
hideHeader	`boolean`	`false`	Specifies if the header of the grid will be hidden. The header is visible by default. The header includes column headers and the filter row.
isDetailExpanded	`(args: RowArgs) => boolean`		A function which determines if a specific row is expanded.
isGroupExpanded	`(args: GroupRowArgs) => boolean`		A function which determines if a specific group row is expanded.
loading	`boolean`	`false`	Specifies if the loading indicator of the Grid will be displayed (see example).
navigable	`GridNavigableSettings`		If set to `true`, the user can use dedicated shortcuts to interact with the Grid. By default, navigation is disabled and the Grid content is accessible in the normal tab sequence. To enable navigation through separate Grid sections only, provide a `GridNavigableSection` array.
pageable	`boolean \| PagerSettings`	`false`	Configures the pager of the Grid (see example).
pageSize	`number`		Defines the page size used by the Grid pager. Required by the paging functionality.
reorderable	`boolean`	`false`	If set to `true`, the user can reorder columns by dragging their header cells (see example).
resizable	`boolean`	`false`	If set to `true`, the user can resize columns by dragging the edges (resize handles) of their header cells (see example).
rowClass	`RowClassFn`		Defines a function that is executed for every data row in the component (see example).
rowHeight	`number`		Represent the actual height of each Grid row (`tr`) element in the DOM. Required by the virtual scrolling functionality. Set the `rowHeight` option to the exact pixels as the height of the `tr` element appears in the DOM.
rowReorderable	`boolean`	`false`	Enables the row reordering of the Grid.
rowSelected	`RowSelectedFn`		Defines a Boolean function that is executed for each data row in the component (see example). Determines whether the row will be selected.
rowSticky	`RowStickyFn`		Defines a function that is executed for every data row in the component, and determines whether the row will be sticky, i.e. always visible after scrolling.
scrollable	`ScrollMode`	`'scrollable'`	Defines the scroll mode used by the Grid.
selectable	`boolean \| SelectableSettings`	`false`	Enables the single-row selection of the Grid.
size	`GridSize`	`'medium'`	Specifies the sizing of various Grid building blocks (e.g. tables, buttons, inputs, dropdowns, etc.)
skip	`number`		Defines the number of records to be skipped by the pager. Required by the paging functionality.
sort	`SortDescriptor[]`		The descriptors by which the data will be sorted (see example).
sortable	`SortSettings`	`false`	Enables the sorting of the Grid columns that have their `field` option set.
trackBy	`TrackByFunction<GridItem>`		A function that defines how to track changes for the data rows. By default, the Grid tracks changes by the index of the data item. Edited rows are tracked by reference. See example
virtualColumns	`boolean`	`false`	If set to `true`, the grid will render only the columns in the current viewport.

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.

Applies the minimum possible width for the specified column, so that the whole text fits without wrapping. This method expects the Grid to be resizable. The method must be executed after the Grid is already populated with data. See example

Parameters
column	`ColumnBase`

autoFitColumns

Adjusts the width of the specified columns to fit the entire content, including headers, without wrapping. If no columns are specified, autoFitColumns is applied to all columns.The method must be executed after the Grid is already populated with data. See example

Parameters
columns	`ColumnBase[] \| QueryList<[ColumnBase]({% slug api_grid_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
index?	`number`	The row index that will be switched out of the edit mode. If no index is provided, it is assumed that the new item editor will be closed.

collapseGroup

Collapses a group header item for the given index. For example, 0_1 collapses the second inner group of the first master group.

This method is provided only for backwards-compatibility with legacy versions. These versions tracked the expanded group state internally using the hierarchical group index.

The collapseGroup method is not supported when you use the kendoGridGroupBinding directive.

When a Grid is pageable, the indexes of the groups are offset by the current Grid skip.

Parameters
index	`string`	The underscore separated hierarchical index of the group.

collapseRow

Collapses the specified master row (see example).

This method is provided only for backwards-compatibility with legacy versions. These versions tracked the expanded state internally using the data row index.

For new development, use the kendoGridDetailsExpandBy directive or provide an isDetailExpanded callback. See Controlling the Expanded State for examples on how to control the expanded state.

Parameters
index	`number`	The data row index of the master row.

drawPDF

Exports the Grid element to a Drawing Group by using the 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 (see example).

Parameters
rowIndex	`number`	The data row index that will be switched in the edit mode.
column	`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
rowIndex	`number`	The data row index that will be switched in the edit mode.
group?	`FormGroup`	The FormGroup that describes the edit form.
options?	`EditRowOptions`	Additional options configuring the focus target once the editor opens.

expandGroup

Expands a group header item for the given index. For example, 0_1 expands the second inner group of the first master group.

This method is provided only for backwards-compatibility with legacy versions. These versions tracked the expanded group state internally using the hierarchical group index.

The expandGroup method is not supported when you use the kendoGridGroupBinding directive.

When a Grid is pageable, the indexes of the groups are offset by the current Grid skip.

Parameters
index	`string`	The underscore separated hierarchical index of the group.

expandRow

Expands the specified master row (see example).

This method is provided only for backwards-compatibility with legacy versions. These versions tracked the expanded state internally using the data row index.

For new development, use the kendoGridDetailsExpandBy directive or provide an isDetailExpanded callback. See Controlling the Expanded State for examples on how to control the expanded state.

Parameters
index	`number`	The data row index of the master row.

focus

Focuses the last active or the first cell of the Grid.

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 Grid and does not correspond to the data item index. Header rows are included, starting at index 0. Group headers and footers are included. The row indexing is absolute and does not change with paging.

If the Grid 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.

reorderColumn

Changes the position of the specified column. The reordering of columns operates only on the level which is inferred by the source column. For the reorderColumn method to work properly, the source column has to be visible.

Parameters
source	`ColumnBase`	The column whose position will be changed.
destIndex	`number`	The new position of the column.
options	`ColumnReorderConfig`	Additional options.

saveAsExcel
Initiates the Excel export (see example).

saveAsPDF
Initiates the PDF export (see example).
