Migrating from 2.9 to 3.0: FeatueLayer.RemoveAllDefinitionFilters() replaced by FeatureLayer.RemoveAllDefinitionQueries()?

[Amadeus111]

I am updating my AddIns and switching to SDK 3.0/.Net 6 

FeatueLayer.RemoveAllDefinitionFilters() is not resolved the closest function I found is FeatureLayer.RemoveAllDefinitionQueries().  The same issue exists also with FeatureLayer.DefinitionFilter but there is FeatureLayer.DefinitionQuery. I still have many errors I can't run my AddIn. Is there anyone who knows my assumption is right?

that is correct. RemoveAllDefinitionQueries() will do the same thing

Hi,

At 3.0, BasicFeatureLayer definition queries have changed.  The ProConcepts: 3.0 Migration Guide covers this topic.  There are also various code snippets that can help you in this wiki.

 var us_states = MapView.Active.Map.GetLayersAsFlattenedList()
                     .OfType<FeatureLayer>().First(lyr => lyr.Name == "US States");

 QueuedTask.Run(() => {
    us_states.SetDefinitionQuery("STATE_NAME = 'Iowa'");
    //equivalent to...
    var def_query = new DefinitionQuery() {
      Name = "A Name that is Unique",
      WhereClause = "STATE_NAME = 'Iowa'"
   };
   us_states.InsertDefinitionQuery(def_query, true);

   var active_def_query = us_states.ActiveDefinitionQuery;
   string where_clause = us_states.DefinitionQuery;//just the where clause string
   
  //remove the active query
  us_states.RemoveActiveDefinitionQuery();

  //remove using name
  us_states.RemoveDefinitionQueries(new List<string> { def_query.Name });

  //use LINQ to get just a specific query
  var def_query = us_states.DefinitionQueries.FirstOrDefault(
                                         dq => dq.Name == "Query def name");
