I believe reportdatasource(_rdc) expects IEnumerable Collection, while you are passing DataTable, which is not an IEnumerable Collection. So it throws the error.

Employees.EmployeesDataTable _emp;
_emp=_emp_adapter.Get_Employees_By_Dept(deptid);
DataTable dt = _emp.Table;
_rdc.SetDataSource(dt);

if(!Page.IsPostBack)
   {
    //BindGridViewData. 
   }

How do am I get selected row's data (Like ID)?

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
   {
       int  ID= Int32.Parse(GridView1.Rows[GridView1.SelectedIndex].Cells[0].Text);
   }
