Calcuate maximum number of rows in a given category

Hi,

I have a dataset in SSRS report. The dataset has two columns Category and Product.

(Note: DataSet is not attached to a table/matrix)

Requirement: I need to calcuate the number of rows in each category and then findout the maximum number among the row count for each category.

For Ex:

No. of rows in Category 1: 3

No. of rows in Category2: 2

No. of rows in Category3: 2

Maximum number among (3,2,2): 3

Thanks

NC
