Aggregates, display all groups

[invivo]

Hello,

I would like to know if there is any way to show empty groups in the gridview when aggregates functions are used ?

For exemple :
I have these datas :
groupA sample
groupA sample2
groupB sample3

Actually, I see this :
groupA Count : 2
groupB Count : 1

And now I want to see this :
groupA Count : 2
groupB Count : 1
groupC Count : 0

It is possible to have this ?
Can we defined groups for the aggregates and so see also empty groups ?


Thanks !

Hi,

That is not possible. You can't display something which does not exist in the actual data.

Try doing LINQ GroupBy over a set of data. It cannot return groups which do not exist in the data.

Hi,

Actually, I will try to explain this in another way. For example you want to see groupC with count 0.

Why not groupX or groupY ot groupSomething else. In other words the set of possible zero=-count groups is the infinite set.

No one knows what can exist if it does not actually exist.

Yes, I understand what you explain, and I knew that.

But my question was, if there any way to give "groups" to the aggregate function (so, not dynamicaly with datas) and thereby display all groups ?
