Hi Krzysztof,
You seem to use the correct approach for grouping using code. In this case the only problem I can suspect is that in your case "Grupa" does not refer to any grid columns' UniqueName. Note that RadGrid uses UniqueName property of its columns in the group by, filer or sort expressions.
You may have confused it with the FieldName property. Generally UiqueName is autogenerated baaed on FieldName, but i some cases these two properties can have different values. For example in the case when you have two columns bound to the same data-field.
Another "gotcha" is that RadGridView would not show any error if you try to group by non existing columns, because this feature is designed to work in late-binding scenarios. For example you can add group-by expression first, then grid columns, then data - and this actually happens when you design the grid in Visual Studio. I hope this information was useful and will help you resolve this issue.
Let me know if the problem persists.
