Dear All,

I am using Ado.net Entiry data model in my asp.net application.

After I drag my Task table from database, it will create query:
this._Tasks = base.CreateQuery<tasks>("[Tasks]");

I want to add condition here to select task by taskID.

Please help/suggest me on this.

No. You need to create new file with new class. F.e. TaskRepository where you'll implement your DAL. Edmx file generated by Entity Framework needs to provide mapping between your DB and yourDBentities class.

Thanks for your reply.
The method which you are telling me is need to write in .svc file..
like

XML

[WebGet]
        public ObjectResult<Tasks> GetTaskById(int TaskID)
        {
            TasksDBEntities entities = new TasksDBEntities();
            return entities.GetTaskById(TaskID);
        }

isn't it ? please reply so that i can proceed.

Solution 1

To get task by id you need to implement it in separate method, f.e. GetTaskById(int taskId). And this line is generated to access to Tasks table by EF

this._Tasks = base.CreateQuery<tasks>("[Tasks]");

So, don't try to change it.

Solution 3

public Task GetTaskById(int taskId)
{
   yourDBEntities db=new yourDBEntities ();
   return db.Tasks.Where(task=>task.TaskId=taskId);
 }
