The Definition Expression determines what's obtained from the data source, so if you change that it will make a new request (hence the delay). Display Filters just work with the data in hand. Sounds like you want to use a <A href="https://developers.arcgis.com/net/api-reference/api/netwin/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Mapping.ManualDisplayFilterDefinition.html" target="_blank"><STRONG>ManualDisplayFilterDefinition</STRONG></A>.</P> Mon, 11 Apr 2022 16:00:16 GMT https://community.esri.com/t5/net-maps-sdk-questions/definitionexpression-features-hide-show-speed/m-p/1163089#M10892 Nicholas-Furness 2022-04-11T16:00:16Z
