I wanna have my Group Header Row with aggregates in columns, like happens with PivotGrid.
I've done a Style like this:
<Setter Property="ShowGroupHeaderColumnAggregates" Value="True" />
<Setter Property="ShowHeaderAggregates" Value="False" />
But the result is double lines: one for group title and another to aggregates.
I wanna aggregates in same line that group title but in collumns.
