Hi Ashish,
Thanks for contacting Syncfusion Support.
We have achieved your requirement “Need to set label to the Dropped shape”. When a Node is dragged and dropped from SymbolPalette, DiagramView’s NodeDrop event will be fired. Similarly for LineConnector, ConnectorDrop event will be fired. We have provided sample to represent this. Please refer to the sample from the following link.

We have incremented the label value, if same shape is dropped from the SymbolPalette to the Diagram. We have provided screenshot to represent this. Please refer to the below screenshot.
