Hi, We are using Telerik 2017.1.228.45 RadTree controls. We have implemented RadTree contract inside a usercontrol and it's getting called through a master page. all Radtree nodes has a customUrl field populated,so when they are clicked on the same page, a user control appears and when some changes are made to that user control and is closed, RadTree loses its expanded state.

 

Is there a way to persist RadTree in that expanded state please? if yes, then how?

 

Thank you

Hello Vivek,

You can try using the persistence framework to achieve this requirement:

https://demos.telerik.com/aspnet-ajax/persistence-framework/examples/overview/defaultcs.aspx

I hope this will prove helpful.
