I created a simple point feature class in default gdb in ArcGIS Pro and published it as a web layer with enabling edit and sync data to ArcGIS online. Other staff edited this web layer and I can see his edit in ArcGIS pro after refreshing web layers. However my original gdb is still in-tact and I wonder how I can bring the changes into gdb not just on published web layer in ArcGIS online. ... View more

I just noticed that I need to install ArcGIS Image Server on separate machine from ArcGIS Server instance for 10.6 version. We store raw Ortho photo imagery(1.75TB), Lidar data(554GB), Cached basemap(21GB) images on the other machine(enterprise Geodatabase machine(SDE)) and plan to create a VM to install image server. I'd like to know the minimum server specs for image server. Do you think that dual core CPU/8GB RAM/200GB Hard drive is good enough? Thanks, ... View more

I created a button to select a graphic(points) with polygon extent. What I'd like to do is when it selects points, its attributes are populated in datagrid and highlight corresponding graphic when mouse over on an each item in datagrid.

I'd like to populate more fields in datagrid in 'select graphic within extent' sample code(http://resources.esri.com/help/9.3/arcgisserver/apis/flex/samples/index.html).
