Hi,
I want create and binding xamTreeMap at code.
In XAML page I created xamTreeMap:

<ig:XamTreemap x:Name="XamTreeMap_1" LayoutType="Squarified" LayoutOrientation="Horizontal" />

In code I do this:

List

<Prekess> pr1 = new List<Prekess>();
pr1.Add(new Prekess { name = "Preke 1", kaina = 10000 });
pr1.Add(new Prekess { name = "Preke 2", kaina = 1000 });
pr1.Add(new Prekess { name = "Preke 3", kaina = 20000 });
pr1.Add(new Prekess { name = "Preke 4", kaina = 7000 });
pr1.Add(new Prekess { name = "Preke 5", kaina = 15000 });

List<Prekess> pr2 = new List<Prekess>();
pr1.Add(new Prekess { name = "Preke 6", kaina = 10000 });
pr1.Add(new Prekess { name = "Preke 7", kaina = 1000 });
pr1.Add(new Prekess { name = "Preke 8", kaina = 20000 });
pr1.Add(new Prekess { name = "Preke 9", kaina = 7000 });
pr1.Add(new Prekess { name = "Preke 10", kaina = 15000 });

List<Pelnass> p = new List<Pelnass>();
p.Add(new Pelnass { id = "Vienas", Prekess = pr1 });
p.Add(new Pelnass { id = "Du", Prekess = pr2 });

XamTreeMap_1.ItemsSource = p;

new Infragistics.Controls.Charts.NodeBinder
{
TargetTypeName = "Pelnass",
TextPath = "id",
ItemsSourcePath = "Prekess"
});

new Infragistics.Controls.Charts.NodeBinder
{
TargetTypeName = "Prekes",
TextPath = "kaina",
ItemsSourcePath = "name"
});

But it not working.
I see this message:
There are not anyvalid treemap nodes. Please check the items source and the data binders.

Can anyone help me?

Thanks,
