Hello Selva,
I am just checking your progress on the issue. If you require any further assistance please do not hesitate to ask.
Thank you for your post. I have been looking into it and have created a small sample for you. You can create two separate context menus – one for the HeaderLabelArea and one for the DataRecords, displayed in the grid. Please find the attached sample and do not hesitate to contact us if you have any further questions.
