Question

I keep getting this error with my below LINQ statement, and I can’t figure out why.

The text data type cannot be selected as DISTINCT because it is not comparable.

var reportLoad = from dash in
                 (from rl in QVuser.QlikViewPermissions
                  join d in QVuser.QlikViewDashboards on rl.DashboardId equals d.DashboardId
                   where rl.UserId == user && rl.Active == true
                   group rl by new { DashName = d.DashboardName, DashProdLink = d.ProductionLink, DashTestLink = d.TestLink } into g
                   select new { DashName = g.Key.DashName, DashProdLink = g.Key.DashProdLink, DashTestLink = g.Key.DashTestLink })
                       select new
                       {
                            DashName = dash.DashName,
                            DashLink = (whichServer.UseProductionServer ? dash.DashProdLink : dash.DashTestLink)
                       };

this.DataList1.DataSource = reportLoad;
this.DataList1.DataBind();

I figured it out.

var reportLoad =    from d in QVuser.QlikViewDashboards
                    orderby d.DashboardName
                    select new
                    {
                    DashName = d.DashboardName,
                    DashLink =
                             from dd in QVuser.QlikViewDashboards
                              join p in QVuser.QlikViewPermissions on d.DashboardId equals p.DashboardId
                              where p.UserId == user && p.Active == true
                              group dd by dd.DashboardName into g
                              select (whichServer.UseProductionServer ? d.ProductionLink : d.TestLink)
                    };
