I'm grouping the data like the documentation says:
<Syncfusion:GroupColumnDescription ColumnName="MyRowId" />
It's working fine but it's not completely what I'm looking for.
This piece of code makes the view of the datagrid richer with an expandable row which can be clicked to show the grouped data (or AutoExpandGroups on control).
Is there a way to hide the expandable group row? So it is always automatically expanded and that this expandable row is not visible?
