Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
This layer is backed by memory and is typically used for temporary features.
InMemoryFeatureLayer(IEnumerable<FeatureSourceColumn>,IEnumerable<Feature>)
InMemoryFeatureLayer(IEnumerable<FeatureSourceColumn>,IEnumerable<BaseShape>)
DrawException(GeoCanvas,Exception)
DrawExceptionCore(GeoCanvas,Exception)
OnDrawingProgressChanged(DrawingProgressChangedEventArgs)
You should set the column names for the data that the InternalFeatures will hold. For example, if you have some features that represent road signs, then one column you may want to add is “Sign Type”. Then, for every Feature you add to the layer, you need to add the “Sign Type” and a value to the InternalFeatures' ColumnValues dictionary. If you provide this information, then you can use things like ValueStyles, Labeling, etc. based on the columns you have defined.
This property gets the dictionary that holds your InternalFeatures.
The dictionary is a quick way to access your InternalFeatures. You can easily add, remove or edit features in this dictionary and they instantly take effect in the layer. You can always use the EditTools to do the same thing, but this is a shortcut, as the data is backed in memory so it is very pliable.
This property checks to see if a Layer has a BoundingBox or not. If it has no BoundingBox, it will throw an exception when you call the GetBoundingBox() and GetFullExtent() APIs. In InMemoryFeatureLayer, we override this API and mark it as true.
The default implementation in the base class returns false.
