Dashboard GridView renaming with code

Hi all
I have a customised dashboard with 5 gridviews based on days of the week- see attached photo
How can I change the title of each gridview based on the day of the week (Monday - Friday) i.e how can I reference this field within the c# code??

Each tab is a listviewpanel from a dashboard with a myGrid underneath.

All help appreciated!
Thanks
AW
