ReplaceDatasource Method (Map)

ArcGIS.Desktop.Mapping Namespace > Map Class : ReplaceDatasource Method
A Datastore that you want to find and be replaced with the replaceDatabaseStore parameter depending on the value of the validate parameter.
A Datastore that you want to replace to.
(Optional) -true- the workspace will only be updated if the replaceDatabaseStore value is a valid workspace. If it is not valid, the workspace will not be replaced.
-false- the method will set the workspace to match the replaceDatabaseStore, regardless of a valid match. In this case, if a match does not exist, then layers and standalone tables would appear broken.
