Radtreeview not updating

By setting the Check Mode property to Three State, every check box can display one of these three states: Unchecked, Indeterminate and Checked. ; // Use this method to update the state for all child nodes of this node Update Child(node); // Use this method to update the state for all parent nodes of this node Update Parent(node); // Resume the calling of Before Check and After Check events suspend Call Back = ' Use this method to update the state for all child nodes of this node Update Child(node) ' Use this method to update the state for all parent nodes of this node Update Parent(node) ' Resume the calling of Before Check and After Check events suspend Call Back = ' Use this method to change the Check State of the child Node, ' without triggerring the Before Check and After Check events ' View1. Check State = state ' Repeat the whole cycle for other child nodes Update Child(child Node) ' Use this method to change the Check State of the node, ' without triggerring the Before Check and After Check events ' View1.

However, the check box value is not automatically updated for any child or parent node. Change Check State(parent Node, state); parent Node.

This is what causes the second person (Jane Doe) to be initially selected and expanded, as shown on the screenshot.

The most interesting part happens when I set the Is Expanded and Is Selected properties on the object.

Add(new Person() { Name = "Jenny Moe", Age = 17 }); Person person3 = new Person() { Name = "Becky Toe", Age = 25 }; persons. I add the persons to a list, which I assign as the Items Source of the Tree View, which, with a bit of help from the defined template, renders them the way they are shown on the screenshot.
