@Ajanthan I checked the enhancement request :

below is the response from the Engineering team, who closed that request: Refresh section is designated as the way to reset the state of the grid. That is, refresh section will clear the filter /sort orders by design. This feedback FDBK-17427 here is asking for retaining the filter / sort state on refresh section as well. I don’t think we want do this. Restating the problem in a different way, what we are looking for is a declarative mechanism of grid refresh which retains its sort/filter state. That is, add support for ‘Refresh when’ option for Grid (similar to other layouts) with a further configure to determine whether or not Grid retains state. Users can configure a refresh when based on changes to underlying model changes - Example here: Condition D_pyWorklist.pxCreateDateTime changes, refreshes the Worklist grid sourced from this page. This is now linked to a new Enhancment request (US-202287) and this post has been referenced in our enhancement system. Please take this feedack id and bring it to your Account Executive for next steps.

For now, it is standard behaviour that a reload Section is getting triggered, so whenever a Section is reloaded the filters will automatically be removed

The product team have always proposed the suggestions in our articles:
