Hi all,

I selected a table from db and while bind gridview i am getting following error message,

Data binding directly to a store query (DbSet, DbQuery, DbSqlQuery, DbRawSqlQuery) is not supported. Instead populate a DbSet with data, for example by calling Load on the DbSet, and then bind to local data. For WPF bind to DbSet.Local. For WinForms bind to DbSet.Local.ToBindingList(). For ASP.NET WebForms you can bind to the result of calling ToList() on the query or use Model Binding, for more information see http://go.microsoft.com/fwlink/?LinkId=389592.

and my code is,

public void fngetdata()
        {
            using (BASdbContext objFeeSch = new BASdbContext())
            {
                gvFeeSchedule.DataSource = from data in objFeeSch.FEE_SCHEDULE
                                           select data;
                gvFeeSchedule.DataBind();
            }
            
        }

Thanks in Advance :-)

What I have tried:

public void fngetdata()
        {
            using (BASdbContext objFeeSch = new BASdbContext())
            {
                gvFeeSchedule.DataSource = from data in objFeeSch.FEE_SCHEDULE
                                           select data;
                gvFeeSchedule.DataBind();
            }
            
        }

Solution 2

you can use as per documentation and I tested it :)

C#

public void fngetdata()
        {
            using (BASdbContext objFeeSch = new BASdbContext())
            {
                objFeeSch.FEE_SCHEDULE.Load(); // you should add using System.Data.Entity;
                gvFeeSchedule.DataSource = objFeeSch.FEE_SCHEDULE.Local.ToBindingList<FEE_SCHEDULE>();
                gvFeeSchedule.DataBind();
            }
            
        }

Try This...

public void fngetdata()
        {
            using (BASdbContext objFeeSch = new BASdbContext())
            {
                gvFeeSchedule.DataSource = (from data in objFeeSch.FEE_SCHEDULE
                                           select data).ToList();
                gvFeeSchedule.DataBind();
            }
            
        }
