You need to use the ribbon on dashboard view?
If not, it will work with Table Calcutation and Parameter Action.
Create a parameter which have members 'asc' and 'desc', and create field calculating rank of 'C Data'.
Set order of rank with using the parameter.
In both sheets, put rank field on Rows and hide header.
And create sheet that show choices 'asc' and 'desc'. (I use custom shape but it's not necessary.)
Then, you set the sheet on dashboard, make Parameter Action.
Please check attached workbook for detail.
