Topic: Dynamic Grouping possible ? Posted: 16 Jun 2009 at 7:32am
I have 3 columns in my table. I want the report to group by any one of the 3 columns and the user should be able to decide that at run time.
So in my winforms code i have a combo box that lets them select one of the three options and then i am hoping i can set the group by criteria at run time.

create a formula like:
if {?parameter} = "x" then
{table.field1}
else
if {?parameter} = "y" then
{table.field2} etc
Then for set the group to the formula. Brian covers this in his book...main reason that I watch this site and not other. This one concept has made my reports so much more than they were.

Hmmm....I think that there some confusion. Since I am using CRXI in a VS2005 environment....but this is really a bit of a red herring.
Create the formula. Now create a group or change an existing group, in the upper drop down, just scroll down until you see your formula, select it and you're done.

next thing that I would try, would be to drop the formula on the report and see if it displays as expected. I've never used the group expert, but having just played with it, if the the formula is empty or doesn't contain a field, then it doesn't appear. I put a field in it, saved and there it was.
