Delete last row from gridview

if everytime there is an extra row is displaying in gridview , it may be you have checked enable Adding or you have enabled adding from grid please uncheck that or disable that and try

You can use -

GridView.DeleteRow Method

But I seriousely feel you would be bindng data from a source and you may need to change your approach in that case.

 

Check and let me know if it doesn't help.
