CustomDataSetContext.RefreshFeaturePresentation Method
Indicates that a feature in a custom dataset has changed, and its presentation needs to be updated.
RefreshFeaturePresentation(Feature feature, System.Boolean moveOnly)
Indicates that a feature in a custom dataset has changed, and its 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
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.
To support dynamic caching, your dataset must also implement the ISupportsDynamicCaching marker interface, to signal to the CustomDataSetProxy that it does. Otherwise the proxy will throw an exception if used in a cached layer.
