Example

In This Topic
    GetUseSourceMetadata Method (MapMember)
    In This Topic
    Gets whether or not the MapMember stores its own metadata or uses metadata retrieved from its source. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public virtual bool GetUseSourceMetadata()
    Public Overridable Function GetUseSourceMetadata() As Boolean

    Return Value

    True if the MapMember is using source metadata. False if it is using its own metadata
    Exceptions
    ExceptionDescription
    This method or property must be called within the lambda passed to QueuedTask.Run.
    Remarks
    Group layer ignores GetUseSourceMetadata. Sub layer types do not support metadata. They typically have a single source, specified on the parent layer, that controls the metadata.
    Example
    Layer Metadata
    MapMember mapMember = map.GetLayersAsFlattenedList().FirstOrDefault(); //Search for only layers/tables here if needed.
    if (mapMember == null) return;
    
    //Gets whether or not the MapMember stores its own metadata or uses metadata retrieved
    //from its source. This method must be called on the MCT. Use QueuedTask.Run
    bool doesUseSourceMetadata = mapMember.GetUseSourceMetadata();
    
    //Sets whether or not the MapMember will use its own metadata or the metadata from
    //its underyling source (if it has one). This method must be called on the MCT.
    //Use QueuedTask.Run
    mapMember.SetUseSourceMetadata(true);
    
    //Does the MapMember supports metadata
    var supportsMetadata = mapMember.SupportsMetadata;
    
    //Get MapMember metadata
    var metadatstring = mapMember.GetMetadata();
    //TODO:Make edits to metadata using the retrieved mapMetadata string.
    
    //Set the modified metadata back to the mapmember (layer, table..)
    if (mapMember.GetCanEditMetadata())
      mapMember.SetMetadata(metadatstring);
