How to bound a Button placed on Telerik's RowDetailsTemplate to a ICommand in view's ViewModel

[Michael]

Considering this code: 

<telerik:RadGridView ItemsSource="{Binding SearchResults}" RowDetailsVisibilityMode="VisibleWhenSelected">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn Header="First Name" DataMemberBinding="{Binding FirstName}"  />
        <telerik:GridViewDataColumn Header="Last Name" DataMemberBinding="{Binding LastName}"  />
    </telerik:RadGridView.Columns>
    <telerik:RadGridView.RowDetailsTemplate>
        <DataTemplate>
            <Button Command="{Binding OpenView1Command}">Open View 1</Button> <!-- This does not work -->
        </DataTemplate>
    </telerik:RadGridView.RowDetailsTemplate>
</telerik:RadGridView>

The OpenView1Command is defined in my ViewModel. How do I make the binding work?

Hi Michael,

Since the DataContext of the RowDetails is not the one of the whole grid, but rather the corresponding item, the command from the view model cannot be found. What you can try is to expose your ViewModel as a resource and use it a Source of the binding of the command:

<Button Command="{Binding OpenView1Command, Source="{StaticResource MyViewModel}"}">Open View 1</Button>

Thanks for your reply.
Can you give me a sample on how to "expose your ViewModel as a resource"?

But if I don't use MyViewModel as xaml resoulre, how I can do it?.
I am using "datacontext = ViewModel" in code.
I can use ButtonName.DataContext = VM in code, because Button insite DataTemplate, and I can't get it by Name.
