Build Hierarchical grid when using Enity Framework

[Subin]

 

Hi ,

Can you help let me know on building hierarchical grid when data is nested within lists. when i use EF, data will be nested list and i need to call new action method to pull hierarchical data.

Can you help me on this ?

Below is sample class structure.

Class Building

{

    int buildingId

  List < location> loc

}

class Location

{

  int buildingId

  int locationID

List<sublocation>

}

Class Sublocation

{ 

 int id

  string name

}

Hello Subin,

Please refer to the following online demo for hierarchical Grid:

• http://demos.telerik.com/aspnet-mvc/grid/hierarchy

As you will notice, the nested Grid will have its own Read action methods, where an identifying key from the parent is passed to the action.

Hi Konstantin,

Thanks for your reply.

But my nested grid data will be with parent list. I no need to call action separately to to display nested grid.

Below is ex: For building id :1 corresponding nested grid data will be in loc as shown in below.

Can this be achived. Please let me know.

Ex :
Class Building
{
    int buildingId
  List < location> loc
}

Regards,

Kiran

Hi Subin,

You can handle the DetailInit event of the parent Grid and use the approach suggested in the following forum thread:

Hope this helps.
