DataTable.Casesenstive=False is not working

DataTable.Casesenstive=False is not working
Could you please help

@MariaJosephina Can you tell us what task do you actually want to perform in a bit more detail ?

@MariaJosephina, checkout this example on the DataTable.CaseSensitive property:

I want to compare the data in a dataTable irrespective of the cases(uppercase/lowercase) of the data.

I have used the same DataTable.Casesenstive and I mentioned that, it is not working

which approach for filtering the data was used?
