How can I make reports and hide columns at run time with my aspnet app?

Hello. I did a report that has many many columns. I should give the user the
possibility to choose which columns to use with my asp.net program. Is that
possible to do? The only columns that must be shows are the ones that the
user has choosed.

Is that possible. ! !Please help me with links, code, books anythin
neccesary.You can parameterize the report and set the visibilty property on the column to be dependent on the parameter value. If you want to hide mlutiple columns, you will need multiple parmeters or, in SQL 2005, you can have a multivalued parameted. The only downside to this approach is that the body will not shrink with the hidden columns. This can cause problems when printing / exporting the report.
