Matrix: Hide null value row

The matrix that i have contains null values and is creating empty rows. I tried grouping the row and then setting the visible property, but that just hides the entire rows. Is there an expression that i would need to ensure that only the null rows are not visible on the matrix?

Thanks for taking the time to read.

The database tables looks like:

Month Sales Product

- - --

August 2007 700.00 Apples

August 2007 400.00 Oranges
September 2007 380.00 Apples
October 2007 1200.00 Oranges
November 2007 NULL NULL
December 2007 NULL NULL
Jan 2008 400.00 Grapefruit

The matrix looks like:

August 2007 Sept 2007 Oct 2007 Nov 2007 Dec 2007 Jan 2008

Apples 700.00 380.00

Oranges 400.00 1200.00

Grapfruit 400.00

Try filtering these records. You can use the filter within the Matrix properties to filter all records where Product Names are NULL

I actually tried filtering in the edit group searching for nulls but it didn't work.

I did a bit of searching and found that i needing to use this: =IsNothing(Fields!productname.Value) in the filter expression for the group.

Thanks for your help.sql
