Custom aggregate function in crosstab

[armandi]

Hi everybody
I want to apply Crosstab control of stimulsoft
Assume i have a datasource that contains a list of students who attended in a exam plus their marks and etc...
I would like to show them as a Crosstab where a row shows for example age of student and a column shows average of marks.
Every thing is OK and no problem til here.
The problem is that i want to show percentage of passed students out of failed students (for example exam mark is 100 and pass mark is 50) in second column (for example 25% of students of age 25, passed this exam) . it seems an custom aggregate function could solve this problem.
How could i done this work ?
Best regards.
