how to combine the result from differentviews to IQueryable<T> - wpf

Question

i have a list of PlanItems bind to telerik RadGrid and have two views retrieves the result.Each view get different data so how can i get that data into IQueryable
public class PlanItems
{
public int Id{get; set;}
public string Name { get; set; }
public string HV { get; set; }
public string StNumber { get; set; }
public string LDNumber { get; set; }
public string MSId { get; set; }
public string CreatedBy { get; set; }
public string Type { get; set; }
}
I have 2 different views vw_Boys ,vw_Girls and Student Entity
first i got boys_Id and Girls_Id from student Entity
public IQuerable<PlanItems> GetAllStudents()
{
var Id = from v in context.Student
.Include("SBoy")
.Include("SGirl")
where v.CreatedBy_Id == user.Id
select v;
var temp = unp.Select(a=>a.SBoy.boys_Id).Distinct();
var temp1 = unp.Select(a => a.SGirl.girls_Id).Distinct();
var vwboys = from nv in context.vw_boys
where(temp.Contains(nv.SId))
select nv;
var vwgirls= from nv in context.vw_girls
where (temp1.Contains(nv.GId))
select nv;
var Boysresult = from n in vwboys
select new PlanItems
{
Id = n.SId,
Name = n.Name,
HV = n.HV,
StNumber = n.SNumber,
LDNumber = n.LineNumber,
MSId = n.MasterId,
CreatedBy = n.USerName,
Type = n.SubjectType
};
var GirlsResult = from n in vwgirls
select new UnplannedItems
{
Id = n.GiId,
Name = n.Name,
HV = n.GV,
StNumber = n.SujNumber,
LDNumber = n.Lid,
MSId = n.MasterId,
CreatedBy = n.USerName,
Type = n.SubjectType
};
}
my telerikGrid sample
<telerik:GridViewDataColumn Header="StudentID" IsReadOnly="True" DataMemberBinding="{Binding ID, Mdde=OneWay}" />
how can i return the result from above method..how can i combine the result to one.

Answer 1

I would do it something like this.
Add a new property to you class like this. Because you might have to seperate the boys from the girls in a other case:
public class PlanItems
{
public int Id{get; set;}
public string Name { get; set; }
public string HV { get; set; }
public string StNumber { get; set; }
public string LDNumber { get; set; }
public string MSId { get; set; }
public string CreatedBy { get; set; }
public string Type { get; set; }
//new property
public bool IsUnplanned { get; set; }
}
The use a concat between them like this:
var result= (
from n in vwboys
select new PlanItems
{
Id = n.SId,
Name = n.Name,
HV = n.HV,
StNumber = n.SNumber,
LDNumber = n.LineNumber,
MSId = n.MasterId,
CreatedBy = n.USerName,
Type = n.SubjectType,
IsUnplanned=false
}
).Concat
(
from n in vwgirls
select new PlanItems
{
Id = n.GiId,
Name = n.Name,
HV = n.GV,
StNumber = n.SujNumber,
LDNumber = n.Lid,
MSId = n.MasterId,
CreatedBy = n.USerName,
Type = n.SubjectType,
IsUnplanned=true
}
);
Hope this helps

Answer 2

You can union 2 different IQueryable using union extension method :
here's an example

Answer 3

I am not an expert in wpf, but looking at the solution I think you can use a parent class for both Boys and Girls and then add to a list of that class.
lets say both Boy and Girl classes are inherited from Person class, then create
List<Person> personList = new List<Person>()
and add Boys and Girls into this list.
I am not sure whether this is the solution you need
