Help me, please!
This could be achieved by setting the SummaryFooterCaptionVisible property to false and then adding a summary for an additional column that you would not need summary initially. This summary would be used to display the “Total” text on the same row by setting its DisplayFormat property to the text you would like to display.
I am sending a small sample that demonstrates what I have explained above, please test it on your side and let me know if you have any questions.
