Question

So I create plop two gridviews onto page, define BOTH their datasources in code behind :

 protected void Page_Load(object sender, EventArgs e)
        {
            DataTable dt = Common_Users.GetUsersDataTable();
            gvMaster.DataSource = dt;
            gvMaster.DataBind();
            gvDetail.DataSource = dt;
            gvDetail.DataBind();
        }

Then tell the Master gv to use a details row and I open the detailsRow template and (as devexpress says to do) I put the DETAIL gv inside that template.

However, NOW my page_load can no longer fine gvDetail … How do I continue to call gvDetail NOW that its inside of gvMaster?

It is necessary to provide data for detail ASPxGridView by handling its BeforePerformDataSelect event. Check the http://www.devexpress.com/Support/Center/e/E257.aspx example to see this approach in action.
