Work with Selection object

You can manipulate with Grid cells via the API of the selection object. It is possible to get the object of a selected Grid cell or set the selection to a cell. The selection object also allows removing selection from previously selected cells.

Enabling/Disabling Selection object​

Starting from v7.0, you can activate selection of cells via the enable() method of the selection object.

treegrid.selection.enable();

To disable the Selection object, make use of the disable() method of the selection object:

treegrid.selection.disable();

Setting selection to a cell​

To set selection to a particular cell, make use of the setCell() method of the selection object. The method takes the following parameters:

row(object) an object with a cell to be selected
column(object) the config of a column

const row = treegrid.data.getItem(treegrid.data.getId(0));
const column = treegrid.getColumn("population");
treegrid.selection.setCell(row, column);

To make the process of selecting a cell more flexible, you can apply the related events of the selection object:

Removing selection​

Starting from v7.0, you can remove selection from a selected cell/row or from highlighted cells/rows using the removeCell() method of the selection object. The method takes two parameters:

rowId(string|number) optional, the id of a row
colId(string|number) optional, the id of a column

// unselects all previously selected cells
treegrid.selection.removeCell();
 
// unselects all previously selected cells of the specified row
treegrid.selection.removeCell(rowId);
 
// removes selection from the specified cell
treegrid.selection.removeCell(rowId, colId);

To make the process of unselecting cells more flexible, you can apply the related events of the selection object:

Getting object of a selected cell​

To get the object of a selected TreeGrid cell, use the getCell() method of the selection object:

const selectedCell = treegrid.selection.getCell();
// -> {row: {…}, column: {…}}
