RadzenTree's selected node don't clear properly

Hello !

After several tests, the RadzenTree's selected node don't clear properly. My package version is 3.1.10.

Here's my tree :

For reproduce the bug, with a item with a property "Expanded" for expand the node by click on the item instead of the arrow :

  • Click on node 1 and extend it
  • Reset the selected node elsewhere, use a button or something.
  • Click on node 1 again (not the arrow, the arrow works properly) => It select it but don't call the callback for change value

What I do : When I set "SelectedNode" to "null" in a callback of a checkbox, it reset the visual of the tree, the Expanded property works properly.
But when I click again on the same node, it's do not call the callback "OnChangeTree". If I click on an other node, it calls the callback properly.
Try to call "StateHasChanged()" doesn't work either.

Hello again !

Actually, there's no need of a model with an Expanded value or something like that.
The bind-Value set to "null" in the code-behind update UI but not "intern store".

You can reproduce the bug like that :

1- Click on a element of the tree view
2- With an other element of your UI (a button for example), set the bind-Value to "null" in the code behind. => The UI deselect the element
3- Click on the same element of the tree view => The callback "Change" is not called

Hi @Zethzer,

We were able to reproduce the issue based on the instructions from your second post. We will investigate and include a fix in one of the next releases.
