Question
I have a table widget in reporting services where I group rows on a given id.
For each group, I display the number of rows per group, using countrows().
How can I display the average number of rows per group at the end of my report ?
What I am missing is : how to count the number of groups?
Solution
This is from memory - not sure if this expression is correct:
= Count(Fields!ID.Value) / CountDistinct(Fields!ID.Value)
Assuming that the "ID" you're grouping by is a single field, that sort of expression should get you what you want.
