Feature Data Form

This sample demonstrates editing the attribute data of an ArcGISLocalFeatureLayer using an ESRI.ArcGIS.Client.Toolkit FeatureDataForm.

To use the sample, click on a feature in the map to view the attributes in the data form. Edit values in the data form and click ok to save to the database.
