Thank you for your help, Gintautas. I tried another way to settle the problem. I set "MapView.Active.DrawingPaused = true; "before running GP and  "MapView.Active.DrawingPaused = false;" after. That will cause the map rendering suspended and avoid refreshing many times. I think that's an proper way considering current situation. There are still many inconvenience for those who are familiar with ArcObjects but try to use Pro SDK. Sorry for the delay! Dominic ... View more

Hi Gintautas, Thank you for your help. I tried your code but the program get stuck when I run Task.Run() function. I have to make it asynchronous (adding async, await keyword), which again causes the refresh. Since this refresh after join also occurs in ArcPro, I think it must be related to multithread in ArcGIS Pro. ... View more

Thanks, Gintautas. My code is listed as follows: public static async Task < bool > JoinTable ( string sLayerName , string sInField , string sJoinTable , string sJoinField , bool bKeepAll ) {     return await QueuedTask . Run ( async ( ) = >     {         try         {             string sJoinType = "KEEP_COMMON" ;             if ( bKeepAll ) sJoinType = "KEEP_ALL" ;             var parameters = Geoprocessing . MakeValueArray             ( sLayerName , sInField , sJoinTable , sJoinField , sJoinType ) ;             var cts = new CancellationTokenSource ( ) ;             var results = await Geoprocessing . ExecuteToolAsync ( "management.AddJoin" , parameters , null , cts . Token ,                 ( eventName , o ) = >                 {                 //Debug.WriteLine($@"GP event: {eventName}");             } , GPExecuteToolFlags . None ) ;             return ( ! results . IsFailed ) ;         }         catch ( Exception ex )         {             //MessageBox.Show(ex.ToString());             return false ;         }     } ) ; } ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ When I run the Geoprocessing.ExecuteToolAsync() function, all the layers are forced to refresh even if I set GPExecuteToolFlags to None. I can't find a way to avoid that. Thank you very much. ... View more

I'm sorry but that issue still exists. It seems that all GP Tools have this problem even if you set the  GPExecuteToolFlags param. If you run multiple GP Tools at one function, you have to refresh the map again and again even though it's not necessary to  update the map (like the join action). Is there any alternative solution? Thank you very much. ... View more

Thanks, Gintautas. I changed the GP flag to  GPExecuteToolFlags . None and it doesn't flash. Thanks for your help! ... View more

Hi Uma, Thanks for your reply. I can use this method to construct a simple marker with specific style. But I need to get the style property later on -- after I create the symbol object. Currently I cannot find the corresponding property from CIMPointSymbol or CIMVectorMarker. Can you give me ideas? Thank you very much. Best, Dominic ... View more
