It is displaying empty in gridview, I think problem is in Business Object. Please help me. I am fed up,Ii am trying from last night.

In BO.cs:

ASP.NET

namespace Business_Object
{
    public class company:Icompany
    {
        int _empid=0 ;

        public int empid
        {
            set
            {
                if (value != _empid)
                    _empid = value;
                
            }
            get
            {
                return _empid;
            }
          
        }

        string _empname ;

        public string empname
        {
            get
            {
                  return _empname;
            }
            set
            {
                value = _empname;
            }
        }

        int _jobid ;

        public int? jobid
        {
            get
            {
                return _jobid;
            }
            set
            {
                value = _jobid;
            }
        }

        DateTime _hiredate;
        public DateTime? hiredate
        {
            get
            {
                return _hiredate;
            }
            set
            {

Your accessors are back to front.

E.G. You have written

C#

DateTime _hiredate;

public DateTime? hiredate
{
    get
    {
        return _hiredate;
    }
    set
    {
        value = _hiredate; // back to front
    }
}

But what you should have is

C#

DateTime? _hiredate;

public DateTime? hiredate
{
    get
    {
        return _hiredate;
    }
    set
    {
        _hiredate = value;
    }
}

N.B. Notice that I have also had to make the member variable a nullable type too - this is required by the set accessor as you may be passing in a null value
