Hierarchical Data Binding

[Brian]

Hi,
I have a fairly simple object model:

public class Location

{

           public string Name { get; set; }

        readonly List<Location> _locations = new List<Location>();

        public List<Location> Locations

        {

            get { return _locations; }

        }

 

        readonly List<Printer> _printers = new List<Printer>();

        public List<Printer> Printers

        {

            get { return _printers; }

        }

}

 

public class Printer

{

        public string Name { get; set; }

        public string Mapping { get; set; }

        public string AdditionalInfo { get; set; }

        public string Guid { get; set; }

}

So a location can have any number of sub-locations,  and each location can have any number of printers.

I'd like to bind this to a RadTreeView, such that the 'Name' property of the location/printer is shown 

e.g
   Location#1
   Location#2
       Location#3
            Location#4
                 Printer#1
                 Printer#2
            Location#5
                 Printer#3

etc.

The object model is loaded from xml at the moment,  a sample of which can be seen here:

Can this be done with RadTreeView ???

Thanks.

Hi Brian,

The RadTreeView binding functionality does not support this scenario. You can use load-on-demand Nodes loading and Tag property to implement this case. More information about load-on-demand loading you can find in our online documentation.

I hope this information is useful. Let me know if you need further assistance.
