Binding to list of objects containing 2 lists

[Richard]

Hello all,

Scenario:
I am using the latest Radcontrols for Winforms (2011.3.11.1116) and I have a list of classes(categories) comprised of the following:
Name (string)
SubCats (List of objects(1) - each with props (Name, list of Reports))
Reports (List of objects(1) - each with props (list of Reports)) 

Reports is made up of Name and ID

Is it possible to use something like:
.Displaymember = "Name\Name\Name\Name"
.ChildMemeber = "categories\Reports\SubCats\Reports

or am I forced to loop through my class and populate the nodes manually?

Any help is appreciated.

[Richard]

Update: 

I finally just looped through the lists and programmatically built the node list for the tree. 

I'm still looking forward to hearing if there is another approach to binding to this type of data source.

Thanks in advance.

Hello Richard,

You can not present the desired structure using object-relational binding mode. The issue is that the Reports object from the second level does not contain SubCats in its properties. You can present the structure with SubCats at the second level following your description of objects:

.DisplayMember = "Name\Name\Name"
.ChildMember = "categories\SubCats\Reports"

The solution in your case is to loop through the lists and programmatically build the nodes.

I hoe this helps. Let me know if you need further assistance.

Kind regards,
