    Hi :)
    Just need assistance..

    ^I created a function for 'Cancel All' <- once the user hit this button all checkbox must have value false to uncheck it.. I created a script for this trigger (code below)

    this.returnedSamplesData.filter = (item) => { return item.scope = false };

    however, it seems like its not working properly . coz once i trigger the cancell button all records will display none.

    To de-select all the selected rows on click of a button you may iterate over each row and set the isSelected property to false and refresh the collectionView to update the checkboxes state. Please refer to the code snippet below demonstrating the same:

    .html file code:
     <button class="btn btn-primary" (click)="removeSelectionAll(flex,$event)">
    Cancel all

    .ts file code
      removeSelectionAll(grid, e) {
    grid.rows.forEach((row) => {
    row.isSelected = false;
