Quickest way to get Row from OID

Question

I am trying to move some of my code from inspector to Row for the purposes of saving in RowCreate and Change Events. Is there a quick way to get a Row from an OID. I think I am missing something. For instance below, I want the first selected item from the selection set, but I get an OID and need to quickly get the ROW for it. I know I can do the lookup and get the row cursor, but is there an easier way than this to get a Row for a OID than GetRowForOID like I have below? Much like the Inspector does? //I need to get what the user, if multiple, i need to get the first public static Task<Row> GetFirstSelectedRow() { return QueuedTask.Run(() => { try { Row selectedRow = null; // get the currently selected features in the map var selectedFeatures = MapView.Active.Map.GetSelection(); if (selectedFeatures.Count > 0) { // get the first layer and its corresponding selected feature OIDs var firstSelectionSet = selectedFeatures.First(); // load the selected features into the inspector using a list of object IDs if (firstSelectionSet.Value.Count > 0) { selectedRow = GetRowForOID(firstSelectionSet.Key as FeatureLayer, firstSelectionSet.Value.First()); } } return selectedRow; } catch (Exception e) { LogWriter.LogError("FeatureServiceManagement - getFirstSelectedItem", e); return null; } }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ public static Row GetRowForOID(FeatureLayer inFeatureLayer, long inOID) { try { Row ReturnRow = null; if (inFeatureLayer == null) { return null; } string OidFieldName = inFeatureLayer.GetTable().GetDefinition().GetObjectIDField(); QueryFilter qf = new QueryFilter() { WhereClause = string.Format("{0} = {1}", OidFieldName, inOID) }; // apply the query filter to the feature layer in question RowCursor rowCursorSearch = inFeatureLayer.Search(qf); if (rowCursorSearch != null && rowCursorSearch.MoveNext()) { if (rowCursorSearch.Current != null) { ReturnRow = rowCursorSearch.Current; } } return ReturnRow; } catch (Exception e) { LogWriter.LogError("FeatureServiceManagement - GetRowForOID", e); return null; } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I usually use this snippet of code knowing that through a selection I get a dictionary with the MapMember as key and a list of object ids as the value for each MapMember. I am using a single mapmember and the corresponding objectId list as input for my sample method below (I am using similar code but this snippet is only pseudo code): // this in only pseudo code // call from MCT public RowCursor GetRowCursor(MapMember mapMember, List<long> objectIds) { var basicFeatLayer = mapMember as BasicFeatureLayer; if (basicFeatLayer == null) return null; // Create a query filter to fetch the appropriate rows for this mapmember QueryFilter queryFilter = new QueryFilter() { ObjectIDs = objectIds }; return basicFeatLayer.Search(queryFilter); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

yes, you're quite right. It's (Basic) FeatureLayer.GetSelection() that returns a Selection and not Map.GetSelection().

Did you extend the dictionary or something in order to use .search() on it?  I can't get it to work like you have above?
