sort on subgrid/GridDetailsRow

Hi All

Fairly new to typescript/react

I am trying to set the sort properties for a sub grid in a GridDetailsRow component (class DetailComponent extends GridDetailRow )

I have no issue with sort setting on the parent/master grid using the state, ie:

this.state = {
      data: productsInit,
      gridDataState: {
        sort: [{ field: "lineitemnumber", dir: "asc" }],
        page: { skip: 0, take: 100 }
      }

}

But how do I use the global state to set a different sort on subgrids?

Any help would be great, thanks
