[DevExpress Support Team: CLONED FROM T501533: GridView - How to hide the detail view's tab header, group panel and column headers]
My table is a self referencing table so columns of all levels are the same.
I dont need the headers to repeat has you showed. That's fine.
But I need all columns of all levels to aligned as in an XtraTreeView.
I need the XTraView and not an XTraTree because I need footer and sums and I have hudred of hours of coding arrounf the DXGridView.

To align the detail view's columns under the master view's columns, I suggest using the approach demonstrated in the How to keep master and detail view column widths synchronized example.
Please try this approach and let me know if you have additional questions.
