Firstly, many thanks for your reply! 1. I can get all security channels that belong to users currently logged into system..... 2. I can make a Layer including all channels and get individaul channels by queryFeatures() method......and then highlight them......I have tried that method.....but, I want to only display those channels belong to user and hide other channels. Is there any way to do that? 3. let's do it by the other way. as we known, we can do some operation on Feature Layer, such as updating, deleting, adding.........and next, we query some channels belong to user by Feature Layer and draw them into Graphic Layer....If we do this, it is sure to display individual channels,, but we can't do these operation on Graphic Layer, like hightlight() and get form by FeatureForm()?
