Hi. I wrote this code:

C#

string selectedName = dpdCourse.SelectedItem.Value;
      var crs = DB.Courses.Where(c => c.Name == selectedName).First();
      IEnumerable< GaduatedStudent> gaduatedStd = DB.Users.OfType<GaduatedStudent>().Where(gdt => gdt.Id == crs.GdtStdUN);
      GridGaduated.DataSource = gaduatedStd;
      GridGaduated.DataBind();

But I get this error on the last line:

Constructor on type 'System.Data.Linq.Provider.DataBindingList`1[[User, App_Code.x9wmex0v, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]]' not found.

Where exactly are you getting the issue while fetching the data or while binding to the grid.

Hi, While binding to the grid. it sets gaduatedStd as Grid DataSource but when it run (GridGaduated.DataBind();) it throws that error.
