Implementing NGX Datatable filtering on all columns

Question

I\'ve been trying to get this working with no luck. I\'ve been referencing these resources for help: http://swimlane.github.io/ngx-datatable/#filter

Answer 1

here is an example of your code with multiple columns filtering:

updateFilter(filter: string): void {

  const val = filter.trim().toLowerCase();

  this.filteredList = this.items.slice().filter((item: any) => {
    let searchStr = '';
    for (let i = 0; i < this.gridProperties.FilteredColumns.length; i++) {
      searchStr += (item[this.gridProperties.FilteredColumns[i]]).toString().toLowerCase();
    }
    return searchStr.indexOf(val) !== -1 || !val;
  });
}

If I did not made any errors, it should work correctly.
