Hi all,
I have following grid data source:

Field1;Field2
----------------------
Bratislava;NULL          
Bánovce nad Bebravou;NULL        
Bánovce nad Bebravou;1
Bánovce nad Bebravou;NULL

When I perform group by action independently on Field1 or Field2 all works just fine. I get problem when I group by Field1 and then by Field2.
When NULL value is present in Field2, that group gets records from different group by Field1 where Field2 is NULL.
Here is a example what I get in grid (Please see that records in bold and underlined need not to be in the groups):

Field1: Bánovce nad Bebravou
Field2:
               Bánovce nad Bebravou        
               Bánovce nad Bebravou        
               Bratislava   ??
        
Field2: 1
               Bánovce nad Bebravou    1   
   
Field1: Bratislava
Field2:
               Bánovce nad Bebravou     ??  
               Bánovce nad Bebravou 
    ?? 
               Bratislava

Can anyone help me to solve this issue?
Thanks
Regards,
Slavo

Hello Slavomir Cerven,

Unfortunately I have to confirm that this behavior is observed in current official version of the control. I have logged it into our bug-tracking system and it will be resolved in future version of the control. Meanwhile I have updated your telerik points.

Please excuse us for the inconvenience and thank you for notifying us about the problem.

Kind regards,

Hi Vik,

We have to admit you are correct in your observations. Unfortunately the problem appeared to be harder to resolve and at the same keep the current grouping functionality the way it operates currently, but we will once again look into this issue and it will be resolved in future version of the product.

Please, accept our sincere apologies for the caused inconvenience.

Sincerely yours,
