Thank you for the quick reply. I tried this solution and although I didn't receive any errors I was not able to get it to work for me. I'm still only able to get it to auto scroll to the row of the parent grid. I've copied and pasted the excerpt of my code below along with the definition of the variables used.
Telerik Grid: dgv_edi_apps
file_row_index = the row number of the parent grid
ea_child_rec_id = the row number of the hierarchical grid
dgv_edi_apps.TableElement.ScrollToRow(file_row_index);
dgv_edi_apps.Rows[file_row_index].IsExpanded = true;
dgv_edi_apps.TableElement.ScrollToRow(dgv_edi_apps.MasterTemplate.Templates[0].Rows[ea_child_rec_id]);
dgv_edi_apps.MasterTemplate.Templates[0].Rows[ea_child_rec_id].IsSelected = true;
