Error: More than one sibling has the same key value


I am getting the following error, when I try to upload a list of values to a ListBox:

I am not getting the same error when I assign the very same data to a CheckBoxList

It also working on at least Radzen.Blazor Version-"3.3.0", but are getting the error with the latest "3.5.2"

Kind Regards

Hi @Riaan_Havenga,

Indeed the ListBox component will set @key because of the virtualization feature. We will check if we can workaround this.

Hi @enchev

Thanks for your usual prompt reply. I realise that listbox values should normally be unique.
Don't worry, I have managed to do make workaround in my app.
