Hi Diego,
Greetings from
Syncfusion support.
Based on your query,
you are having a grid with initial filtering using observable data , when
you perform any other actions, the filter is
cleared. Unfortunately the issue is not replicated in the sample below.
Sample: https://stackblitz.com/edit/angular-ws2fqv-u4dgsq?file=app.component.ts,order.service.ts
If you still face
the issue, share a simple sample to reproduce the issue or try to reproduce the
issue in the sample provided.
Regards,
Joseph I.
