On my igx-grid, how do I filter one of the columns by default to only values which are true? I see there's an IgxBooleanFilteringOperand class but I can't figure out how to use it. My grid column is defined like so:
<igx-column field="active" header="Active" [editable]="true" [dataType]="'boolean'"></igx-column>
There are two ways you can achieve that:
1. Use the grid filter method.
This is the simples and fastest Pass your column with the filter term and the condition. In your case that would be:
this.grid.filter('active', null, IgxBooleanFilteringOperand.instance().condition('true'));
2. Build a filtering expression tree and pass it to the grid. This is a bit more complicated but you can apply multiple filters and filtering logic at once.
