Selection in Vue TreeGrid component

24 May 2022 / 6 minutes to read

Selection provides an option to highlight a row or cell. Selection can be done through simple Mouse down or Arrow keys. To disable selection in the TreeGrid, set the allowSelection to false.

The treegrid supports two types of selection that can be set by using the selectionSettings.type.They are:

Single - The Single value is set by default. Allows you to select only a single row or cell.
Multiple - Allows you to select multiple rows or cells. To perform the multi-selection, press and hold CTRL key and click the desired rows or cells. To select range of rows or cells, press and hold the SHIFT key and click the rows or cells.

TreeGrid supports three types of selection mode which can be set by using selectionSettings.mode. They are:

Row - The row value is set by default. Allows you to select rows only.
Cell - Allows you to select cells only.
Both - Allows you to select rows and cells at the same time.

Cell Selection

Cell Selection can be done through simple Mouse down or Arrow keys(up, down, left and right).

TreeGrid supports two types of cell selection mode which can be set by using selectionSettings.cellSelectionMode. They are:

Flow - The Flow value is set by default. Select range of cells between the start index and end index which includes in between cells of rows.
Box - Select range of cells within the start and end column indexes which includes in between cells of rows within the range.

Cell Selection requires the selectionSettings.mode to be Cell or Both and type should be Multiple.

To render checkbox in each treegrid row, you need to use checkbox column with type as CheckBox using column type property.

By default selection is allowed by clicking a treegrid row or checkbox in that row. To allow Selection only through checkbox, you can set selectionSettings.checkboxOnly property to true. Selection can be persisted on all the operations using selectionSettings.persistSelection property. For persisting selection on the TreeGrid, any one of the column should be defined as a primary key using columns.isPrimaryKey property.

Checkbox selection Mode

In checkbox selection, selection can also be done by clicking on rows. This selection provides two types of Checkbox Selection mode which can be set by using the following API, selectionSettings.checkboxMode. The modes are;

Default: This is the default value of the checkboxMode. In this mode, user can select multiple rows by clicking rows one by one.
ResetOnRowClick: In ResetOnRowClick mode, when user clicks on a row it will reset previously selected row. Also you can perform multiple-selection in this mode by press and hold CTRL key and click the desired rows. To select range of rows, press and hold the SHIFT key and click the rows.
