UpdateView()
Updates the View that is displayed by the MapControl.Syntax
public void UpdateView ()Remarks
This method should be called each time the presentation in a map should be updated, for instance after the geographic area of the connected View has been changed.
This is an asynchronous operation which means that the update may not have been performed yet when returning from the call to the method.
When a view is connected to a map control, updates will be managed by an internal update scheduler. The scheduler will take into account the current update mode and timer settings, other map controls, as well as explicit update calls from the application, through this method and calls to View.Update. It will also make sure that some extra time is reserved for the application to handle other GUI input events.
The effect of this is that even if you call this method, the actual update may not take place immediately, but might happen after some delay. The method will return immediately and not wait for the update to take place.
The UpdateView overload of this method can be used instead if you want to specify when you want the update to happen.
UpdateView(ViewUpdateKind kind)
Updates the View that is displayed by the MapControl.Syntax
public void UpdateView (
ViewUpdateKind kind
)Parameters
Indicates when the actual update should be carried out.
Remarks
This method should be called each time the presentation in a map should be updated, for instance after the geographic area in the connected View has been changed.
This is usually an asynchronous operation which means that the update may not have been performed yet when returning from the call to the method.
When a view is connected to a map control, updates will be managed by an internal update scheduler. The scheduler will take into account the current update mode and timer settings, other map controls, as well as explicit update calls from the application, through this method and direct calls to View.Update. It will also make sure that some extra time is reserved for the application to handle other GUI input events.
The effect of this is that even if you call this method, the actual update may not take place immediately, but might happen after some delay. The method will return without waiting for the update to take place.
The kind parameter can be used to modify this behavior, and specify when you wish the update to take place. See ViewUpdateKind for more information.
