RadGridView SelectionMode Binding Does Not Work

[Stephen]

I have a SelectionMode Type Property in my ViewModel.  I have that bound to the SelectionMode of a GridView.  I am using INotify, but it doesn't appear that the GridView has any connection to that Property.  I don't get any errors, it just doesn't work.  I have lots of bindings to other things in the XAML that all work fine, so is there a problem trying to bind that particular property?

Hello,

Generally the reason why the Binding does not work would be that that the Source of it cannot be resolved. You can try defining the ViewModel as a StaticResource and then set it as a Source for the Binding of child RadGridView. You can also check the Binding.Source Property as a reference.

Let me know if this works fine.

I have several other bindings for that grid, in the same view model as the one I am trying to use for SelectionMode and they all work fine.

Hello,

It should also work fine even when the Source is not explicitly set. I attached a demo project for a reference.

I see where you created a binding property, then put that in your xaml, but your triggering event is still the user in the code behind.  I need a way to change that value programmatically from the View Model (no user interaction).  I have events in my code behind right now, which do cause the state to change, but if I try to do it from my view model, nothing happens.

Hello,

May I ask you to try isolating the issue in a demo project illustrating your exact setup and attach it in a new support ticket ? You can also take a look at this blog post for a reference on how to isolate an issue. 

That way I can check it locally and advise further.
