Hello Ayyappan,

Since currently this is not built-in feature for our XamDataGrid control, adding drag fill functionality has been determined to be a new product idea.  I have sent your product idea directly to our product management team.  Our product team chooses new product ideas for development based on popular feedback from our customer base.  Infragistics continues to monitor application development for all of our products, so as trends appear in requested features, we can plan accordingly.

If your feature is chosen for development, you will be notified at that time. 

Your reference number for this product idea is PI12040081.
