load related tables in one gridview with EF (Without Join)

Question

Hello Friends, I have 3 tables with relation between them.

for example 

pic 1

 

after this i made a EntityDataModel (EDM) for my database ( DBFirst)

 

 

and i want to load all the data in one datagrid view is it possible for this tables ? 

because one my relations is 1:N 

 

 

 how can i load all data in one datagrid view without Join in linq ( Creating ViewModel or AnonymousType)

 

when  i use that line of code for DataSource Property of Datagridview ... my gridview is like this ..

 

notice that again : i dont want to use join is it possible for entity framework to do this ? 

 

 

 

 Thank You ! ;)
