Hello Telerik,

I am using RadPanelBar in one of my application, Now i need to expand one of the panelbaritems from one of my function in the code-behind.

for example i need to expand the third item in panel bar when i click on a button.

Consider I am binding a list of "Car" objects to a panelbar, now when i am looping through the items of panelbar i am getting each car item.. 

In this case how to i expand the "n-th" item of panelbar..
expecting a solution asap...

thanks,
- Kranthi

Hello Kranthi,

Every ItemsControl has ItemContainerGenerator. An ItemContainerGenerator is responsible for generating the user interface (UI) for its data item. Therefore if you want to expand a certain item from a RadPanelBar, you can do the following:

private void Button_Click(object sender, RoutedEventArgs e) 
    RadPanelBarItem container = panelBar1.ItemContainerGenerator.ContainerFromItem(panelBar1.Items[2]) as RadPanelBarItem; 
    container.IsExpanded = true

I am attaching a sample project for further reference. Give it a try and let me know how it works for you.
