Reload/refresh treview

[Fredrik]

Can I manually refresh or update a TreeView from my ViewModel?

I have a TreeView whitch is connected to a multiple level Dictionary.

Each branch in the TreeView has a number on it. The number represents the number of notes added to the branch combined with the number of notes on the branches below.

When I remove or add a note on a branch the number on the branch is updated.

How ever the number on the branches above it are not updated, even though I refreshed the whole dictionary (all the parents and children).

Thanks in advance!

Hello Fredrik,

For the rows of the RadTreeView to respond to changes, the bound data items need to implement the INotifyPropertyChanged interface. If that is the case, when you update the value of a child branch, you need to also ensure that you invoke a property changed notification for its parents as well.

If you would kindly provide a small sample project which demonstrates your setup and the issue you observe, I'd be more than happy to suggest a possible solution. Would you find this possible?

Thank you for the reply. I realized it was a caching issue.
