mtx-grid: keep rows checkbox selection in case of pagination data from remote #226

Closed SYS64738 closed 10 months ago

Hi, there's a way to preserve rows checkbox selection when data comes from remote (http) after page navigation ? I cannot find a way to check programmatically a row.

Thank you for your support.

There are two ways to achieve

  1. use the rowSelected prop

    <mtx-grid [rowSelected]="rowSelected"></mtx-grid>
    rowSelected = EXAMPLE_DATA.slice(2, 3);

  2. use the CDK SelectionModel

@ViewChild('grid') grid: MtxGrid;
this.grid.rowSelection.select(...);
this.grid.rowSelection.deselect(...);
this.grid.rowSelection.clear();
this.grid.rowSelection.toggle(...);
