MemoryDataSet.RefreshFeaturePresentation Method
Informs the dataset and the containing layer that the feature has been modified and any cached presentation needs to be updated.
RefreshFeaturePresentation(Feature feature, System.Boolean moveOnly)
Informs the dataset and the containing layer that the feature has been modified and any cached presentation needs to be updated.Syntax
public void RefreshFeaturePresentation (
Feature feature,
System.Boolean moveOnly
)Parameters
The feature which has been modified.
Indicates if the feature has only been moved, or if it has been modified in a way that changes the presentation.
Remarks
You must use the Guard class to lock the dataset before you call this method.
Calling this method is required if the dataset is used in an OrdinaryLayer using Dynamic or DynamicAsync caching. If a feature is modified and this method is not called, the layer may reuse its previously cached information, and the changes will not be reflected in the view.
If a point feature has been moved, but no other changes have been made that would change its presentation, you should pass True to the moveOnly parameter. This allows the layer to simply offset any cached presentation for the feature, without re-reading the feature and processing it in the operator chain. But if for instance an attribute that affects the presentation is changed, you need to set moveOnly to False. For all other types of features but points, and in 3D, the moveOnly flag has no effect.
