GridView Data Virtualization

[Xavier]

Hi,

  I need to use the data virtualization in the gridview component. My source is a IQueryable and after enumerating i need sometimes to do another projection and create a dynamic property. My user case is the following:
 
There's 3 tables with the following relationships:
A---B---C---D
1---n----m---m

My query gets the following hierarchical object: 
A
   |
   ---B
        |
        C--D

My GUI has 3 GridView Components, with the following binding each:
Grid 1: {Binding A}
Grid 2: {Binding A/B}
Grid3: {Binding A/B/C.D} //Error

Grid 3 has an binding error because The Current B item has multiple C items and it cannot do a C.Select(s=>s.D) automatically.


How can i using data virtualization do this binding?



Thanks

Hi,

May I ask you to share more information on what is the exact error do you get? I am not sure that I correctly understand those lines: Grid 2: {Binding A/B}. Would you please clarify this code in more details?
