Use the LinkTo property to connect a node with multiple nodes. By default, the LinkTo property is empty. The LinkTo property indicates a list of keys separated by comma, that links to the current node. For instance, if the LinkTo property is "Key1,Key2", the current node draws a link to the nodes with the following keys: Key1 and Key2. Use the Key property to assign a key to a node. The PenWidthLinkTo property specifies the thickness of the lines between nodes. Use the PenLinkTo property to specify the type of the pen used to paint the lines between nodes. The LinkToColor property specifies the color of the links between nodes. The ShowLinks property doesn't affect the links added with the LinkTo property. The LinkToCaption property specifies the HTML caption being shown on the links between nodes. The ShowLinksDir property specifies whether the links between nodes show their directions.
