I'm having some issues with grabbing a list of type "RhsTruck" through Linq and getting them to display.
RhsTruck just has properites Make, Model, Serial etc... RhsCustomer has properties CustomerName, CustomerAddress, etc...
I keep getting the error "Sequence contains more than one element". Any ideas? Am I approaching this the wrong way?
public RhsCustomer GetCustomer(string customerNumber)
{
using( RhsEbsDataContext context = new RhsEbsDataContext() )
{
RhsCustomer rc = (from x in context.custmasts
where x.kcustnum == customerNumber
select new RhsCustomer()
{
CustomerName = x.custname,
CustomerAddress = x.custadd + ", " + x.custcity
CustomerPhone = x.custphone,
CustomerFax = x.custfax
}).SingleOrDefault();
return rc;
}
}
public List<RhsTruck> GetEquipmentOwned(RhsCustomer cust)
{
using (RhsEbsDataContext context = new RhsEbsDataContext())
{
var trucks = (from m in context.mkpops
join c in context.custmasts on m.kcustnum equals c.kcustnum
where m.kcustnum == cust.CustomerNumber
select new RhsTruck
{
Make = m.kmfg,
Model = m.kmodel,
Serial = m.kserialnum,
EquipID = m.kserialno1,
IsRental = false
}).ToList();
return trucks;
}
}
protected void Page_Load(object sender, EventArgs e)
{
string testCustNum = Page.Request.QueryString["custnum"].ToString();
RhsCustomerRepository rcrep = new RhsCustomerRepository();
RhsCustomer rc = rcrep.GetCustomer(testCustNum);
List<RhsTruck> trucks = rcrep.GetEquipmentOwned(rc);
//I want to display the List into a Gridview w/auto-generated columns
GridViewTrucks.DataSource = trucks;
GridViewTrucks.DataBind();
}
