I'm using MVVM to data bind the items of a RadTreeListView to an observable collection.

When the value of the DataMemberBinding is updated in the View-Model, the value is correctly reflected in the RadTreeListView GridViewCell.   But, cells where the value was updated are highlighted, as shown in the attached screenshot.   I would prefer the updated cells not be highlighted.

Hello Keith,

Thank you for the provided image.

This is an interesting behavior. Looking at the image it seems that the cells are selected when its value is updated. May I ask you to share how the value is updated on your side. I have tried to isolate this behavior in a standalone project but to no avail. You can find the project attached to this reply. Can you take a look at this project and let me know what I need to modify, set, add to reproduce it.

I am looking forward to your reply.

Regards,
Dinko

This is not a big deal, so no action necessary, but I wonder if this may be a side effect of having mixed the RadTreeListView with the MVVMLight library which uses a call to RaisePropertyChanged() to notify the view of an updated value?

Hi Keith,

I am not sure what is the exact reason behind this. Looking at the picture in your first post it seems that when the value is updating the cell is selected. Are you using multiple selections? I don't think that this behavior is related to MVVMLight but if you can isolate it in a standalone project I could further investigate it.
