Reporting Services--Stuck with Matrix column

[Payal_e_m]

Hi, I am woking with SSRS Matrix Control. I have the column header -- year, Row--Programme and Data -- No of Students. YEAR ---------------- PROGRAMME | NO OF STUDENTS The Matrix will display all the years as columns which i have in the dataset. I have tried hiding the colums by giving a condition in the Hidden property. It does work leaving blank spaces between the columns. Can anyone tell me How to getrid of the blank spaces between the colums or how to delete the colums of a Matix based on a condition Please? Thanks & regards, Payal
