Databind collections of disparate types

[MartinM]

Hi,
I am able to successfully bind hierarchical data with two levels (for example, "Categories\Products"), but I would like to databind 3 different collections of different types, the result being something like:

+Categories
    CategoryA
    CategoryB
+Products
    Product1
    Product2
+Location
    LocationX
    LocationY

where

public IList<Category> Categories { get; set; }
public IList<Product> Products  { get; set; }
public IList<Location> Locations  { get; set; }


Similar to this question: http://www.telerik.com/forums/treeview-binding-to-multiple-object-types-in-mvvm

Aside from 'selecting' each item into a new common type, is there a better way to do this?

Thanks for your input,

Hi Martin,

Thank you for writing.

In this case you cannot directly bind the treeview to the datasource object. However you can use the load on demand feature and manually populate the nodes. The attached project contains sample implementation of this approach. 

I hope this will be useful.
