Hierarchy Child Template Expansion issue

[Rohan]

I am implementing a grid hierarchy view on my UI. I have used hierarchy child template for this and it has 3 levels layer A, layer B and layer C. Now when I click to expand layer A, it ends up expanding layer B as well.

Is there any way to stop this? I do not want to expand layer B by default. Please suggest few ideas.

Hi Rohan,

In general RadGridView will not automatically expand all of your sub-hierarchies. For a more practical example I attached an updated version of the project from the Three level hierarchy support forum thread. 

A possible way to automatically expand / collapse all of the sub-hierarchies is to invoked the ExpandAllHierarchyItems() / CollapseAllHierarchyItems() methods somewhere in your code or have some other customization. In order to determine what exactly is causing this behavior, could you please provide us with code-snippets of all definitions both in XAML and code-behind connected to RadGridView?

Hi,

Thanks for the reply. I have found out my mistake. I was trying to bind DataLoaded event of second layer with a method which was not working.

I have changed the logic and it is working now.
