Asked On September 12, 2009 05:11 AM UTC

I'm trying to create a selection tree. Whenever a button in a parent node is clicked, the children nodes should all be selected.
My problem is i can't find the containers of the children nodes (TreeViewItemAdv collection) from a parent TreeViewItemAdv

I can manually get a container by calling
ParentNode.ItemContainerGenerator.GetContainerFromItem(childData)

But there's another problem, if the ParentNode is collapsed, the child containers haven't been instantiated. Setting ParentNode.IsExpanded = true does not synchronously generate the item containers as I expected.

How do I solve this problem?
Thank you

Thank you for your interest in Syncfusion products.

We have a method named as AddNodeToSelectedItems() for selecting one or more nodes from the Treeview children collection. We have created a simple sample with all your requirement. Please find the sample from the link given below.
