Hello friends
I would like to disable the checkbox in my radtreeview, but currently I do not find any property for this.
If I am wrong please name the property.
If not then please suggest a wayto do it or any alternative options.
I want to disable checkbox on click on a button and then enable them on click of another button.
Thank you!

Hi Abhishek,
There is no straightforward approach to this scenario. You will have to find the CheckBox in the visual tree of the TreeViewItem and disable/enable it. I've prepared a simple solution demonstrating one possible solution to this scenario. Have a look at it and let me know if it helps.
On a side note, I'd like to inform you that we've just released an online tool that allows you to reduce the size of your Silverlight applications. For more information, please visit http://blogs.telerik.com/blogs/posts/10-06-10/telerik_assembly_minifier.aspx

Hi David Cardona,
You could provide a runnable sample and we will try to investigate your issue in depth. Is your tree bound to a collection of objects ? Can you make sure that you are trying to work with a RadTreeViewItem that is already generated ( usually it happens when it is loaded in the tree root level collection or one of its parent item has been expanded so that the needed item becomes visible. You can find more info on this topic here. Thank you for your cooperation in advance.
All the best,
