[Solved] Gat Parent and Children checked

[jose]

I am working in the RadTreeView control with each element as Checkbox. Each element has children, too type checkebox. When I select a parent who is not expanded, I can not see the children that this has. The selection of the parent automatically generates the selection of the children. Each control element is the type RadTreeview RadTreeViewItems.

What I can do to see the children of each element if like to know what each child belongs to father, I mean the node of each element?

Hi jose,

First of all, it is important whether your treeview is bound to collection of objects or it is declaratively populated (from xaml). When the tree is not bound, you can get the currently selected item`s children like so:

(this.treeView.SelectedItem as RadTreeViewItem).Items

which is equivalent to

this.treeView.SelectedContainer.Items

When your treeView is bound to collection of objects you can access the currently selected business object  children collection with:

(this.treeView.SelectedItem as BusinessItem).Children as ObservableCollection<Businessitem>

(Supposing that your business object`s class is named Businessitem and it exposes a collection of Businessitems named Children and you bind your tree with ObservableCollection).
However, if this is not what you had in mind, could you please send us a runnable sample showing the issue and we could investigate in depth and advice you better.
