Selection in React Gantt component

Selection provides an option to highlight a row or a cell. It can be done using arrow keys or by scrolling down the mouse. To disable selection in the Gantt component, set the allowSelection to false.

To select data, inject the Selection module into the Gantt control.

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

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

Selection mode

The Gantt component supports three types of selection modes that can be set by using the selectionSettings.mode. They are:

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

Row selection is the default type of Gantt selection mode.

Selecting a row on initial load

You can select a row at the time of loading by setting the index of the row to the selectedRowIndex property. Find the following code example for details.

Customize row selection action

While selecting a row in Gantt, the rowSelecting and rowSelected events will be triggered. The the rowSelecting event will be triggered on initialization of row selection, and you can get the previously selected row and current selecting row’s information, which is used to prevent selection of a particular row. The rowSelected event will be triggered on completion of row selection action, and you can get the current selected row’s information through this event. The following code example demonstrates how to prevent the selection of a row using the rowSelecting event.

In the Gantt component, when you click an already selected row, selection will be cleared. While deselecting a row in Gantt, the rowDeselecting and rowDeselected events will occur. The rowDeselecting event will occur on initialization of deselecting row, and you can get the current deselecting row’s information to prevent the deselection of particular row. The rowDeselected event will occur on completion of row deselection action, and you can get the current deselected row’s information.

Cell selection

You can select a cell in the Gantt component by setting the selectionSettings.mode property to cell. You can get the selected cell information using the getSelectedRowCellIndexes method. This method returns the result as an object collection, which has cellIndexes and rowIndex information of the selected cells.

Find the code example below to enable the cell selection in Gantt.

Selecting multiple cells

You can select multiple cells by setting the selectionSettings.type property to multiple and the selectionSettings.mode property to cell. Multiple cells can be selected by holding the CTRL key and selecting the cells. The following code example demonstrates how to select multiple cells.

Customize cell selection action

While selecting a cell in Gantt, the cellSelecting and cellSelected event will be triggered. The cellSelecting event will be triggered on initialization of cell selection action, and you can get the current selecting cell information to prevent the selection of a particular cell in a particular row. The cellSelected event will be triggered on completion of cell selection action, and you can get the current selected cell’s information. The following code example demonstrates how to prevent the selection of the cell using the cellSelecting event.

Toggle selection

The toggle selection allows you to select and deselect a specific row or cell. To enable toggle selection, set the enableToggle property of the selectionSettings to true. If you click the selected row or cell, then it will be deselected and vice versa. By default, the enableToggle property is set to false.
