Grouping by column with (string [] )

[MAE]

I have column "Groups" with type (string[] ) and converter from (string[] to string).

Sample Rows 

1.  Admin, User
2.  Admin
3.  User

After i try to group by column "Groups", i get  next groups rows column "Groups", i get  next groups rows

1.  Admin, User ( - 1 rows)
2.  Admin (1 rows)
3.  User (1 rows)

But i want to get groups

1. Admin ( 2 rows)
2. User (1 rows )

How i can set group separator or other.
Thank!

Hi,

When the user applies a Grouping, then we build a LINQ query to be executed against the source collection. We group the data by the property you have bound the column to (through DataMemberBinding), considering the format you have applied. You can also check our online demo illustrating the same.

In case, you would like to have a different result, you can define and add a generic GroupDescriptor to group the data as you wish.
