Retrieving last 30 days in report viewer

Question

0.00/5 (No votes)

I have a report view in my asp.net C# web page that displays results from a table (table1) in SQL Server 2012. The table gets an entry (new row) everyday. I want to display only the last 30 days from that table in the report viewer. I am using Visual Studio Community 2015 and I tried selecting the (row) in design mode and from the Tablix Properties I went to the "Filter" option and was trying to sort by (coloumn1) for the last 30 days to be displayed. I get it manually by selecting >= 12-26-17 but putting a formula in lieu of a date does not work.
Please advise. Thank you.

What I have tried:

Under Talbix Properties I have selected to sort by two dates:

=Fields!CNBDATE.Value
Between

12/26/2016 00:00:00
01/26/2017 00:00:00

I have also tried the following code (but it did not work)
DATEADD(DAY, -30, GETDATE())

Thanks, I did this before but thought I would be able to run the sql command on the web side rather than create another view. I appreciate the feedback.

Add the filter to your query, rather than the report:

SQL

SELECT
    CNBDATE,
    ...
FROM
    YourTable
WHERE
    CNBDATE >= DateAdd(day, -30, Convert(date, GetDate()))
;
