Hi,
I have an issue, when the Child node is Collapsed and you are checking the Parent node then it keeps only Parent node data (including the child node), but when the Child node is expanded, and you are checking all elements of the expanded child node then it keeps child node elements and parent node (included child node) together, so it happens duplicated values. Could you, please, advise?
Thanks,
Elena
Can you provide more details on how to replicate this. You can post a code example using the code of some of our demos.
Hi!
Sorry for disturbing you.

I’ve seen today already exact the same code posted by some other user, are you using two accounts for our forum? I would like to kindly note that this violates our forum rules - if you don’t respect them we will discontinue your account. Try to attach Radzen.Blazor source code to your project to debug your case - if you believe that you’ve found something wrong you can submit pull request with a fix - we are open source after all.
Hi!
He is my teammate and we are working on the same project. That's why we have trouble with this issue.
Thanks,
Elena
