How to deselect single row from mat-table

Question

I'm using the Selection Data table

to deselect all the rows we use:

this.selection.clear();

where selection is an object of SelectionModel class. Now what if I want to remove the selection of specific row from code behind "component typescript code", is there any helpful "angular" statement just like clear() method?

Answer 1

You can use

this.selection.deselect(row)

this.selection.select(row)

Sample to deselect 5th row with mat-table

function to do select or deselect specific row.

Example: If you want to deselect 3rd row you can do following.

this.selection.deselect(this.dataSource.data[2])

This the SelectionModel class code
