How to add Node at run time from SymbolPalette?

How to add SymbolPalette Symbols  to exsisting Nodecollection /Nodes  which are in different Layers once the symbol is dropped on the Diagram in DragEnter Event?

[Shyam G]

Hi Mounika, 

By default, when we drag a node from the symbol palette and drop it onto the diagram, it will be automatically added into the nodes collection. We need not use any event to update the nodes collection. We have created a sample in which we have rendered the symbol palette and the diagram control. We have added a button to know the nodes count in the diagram. Please refer to a sample below.
