How to set Child GridView DataContext to underlying VM, not the selected item of the parent GridView?

[Dean]

By default the DataContext of a child GridView is the selected item of the parent GridView. How would I change this so that the DataContext of the child GridView is the ViewModel of the containing UserControl which is also the DataContext of the parent GridView?

It is important to note that this VM is dynamically instantiated in code and not in XAML of the UserControl because this UserControl is one of several UserContorls which are used as dynamic Content of an area of a parent Window.

Hi,

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.

No, I clearly stated that the VM is instantiated dynamically and explained why it must be instantiated that way.

Hello,

I apologize for this. You can do the same in code. The point is that you need to specify a valid Source for the Binding.

If this does not help, may I ask you to open a new support ticket and attach a demo project to illustrate your implementation there? That way I will be able to advise further.
