Format entire row if a particular cell in the row is not empty

Question

I want to format the whole row depending on if a particular cell in that is empty or not. I want conditional formatting to go through all rows and say add a background color if column C in that row is not empty.

How do I fix this?

Answer 1

For illustration assuming "whole row" is ColumnsA:Z inclusive, please try Format - Conditional formatting..., Custom formula is:

=$C1<>""   

with formatting of your choice and Range: A:Z.
