How to find out if row item is blank?

I have 2 columns in a workbook - Ship Date & Delivery Date. I need to filter both the columns together and find out if there are any blank cells in both columns.

How can we achieve this ?

Thanks.

hi @susbasu

check even this if condition string.IsNullOrEmpty(row(“Column Name”).ToString

try if else condition if shipdate==0 or <0
