DataContext inheritance issue

[Seekeer]

I have following code:

    <TabItem Header="Accounts"
                 d:DataContext="{Binding AccountsViewModelAccounts}"
                 >
            <StackPanel>
                <DataGrid AutoGenerateColumns="False" Name="accounts" Grid.Row="1"
                          Items="{Binding CollectionView}" >
                    <DataGrid.Columns>
                        <DataGridTextColumn Binding="{Binding Path=Name}" Header="Name" Width="150" IsReadOnly="True"/>
                    </DataGrid.Columns>
                </DataGrid>
            </StackPanel>
        </TabItem>

And got error. But when I move DataContext to grid I got items from AccountsViewModelAccounts.CollectionView

        <TabItem Header="Accounts"
                 >
            <StackPanel>
                <DataGrid AutoGenerateColumns="False" Name="accounts" Grid.Row="1"
                 d:DataContext="{Binding AccountsViewModelAccounts}"
                          Items="{Binding CollectionView}" >
                    <DataGrid.Columns>
                        <DataGridTextColumn Binding="{Binding Path=Name}" Header="Name" Width="150" IsReadOnly="True"/>
                    </DataGrid.Columns>
                </DataGrid>
            </StackPanel>
        </TabItem>

In WPF both piece of code will lead to the same results.

And got error.

What error?

In WPF both piece of code will lead to the same results.

Just to be clear, it's only a previewer related issue? As you are using design data context. Or the same issue with normal data context usage? Like, settings "DataContext" instead of "d:DataContext".

What error?

DataGrid is trying to bind to TabControl's DataContext.CollectionView not DataContext.AccountsViewModelAccounts.CollectionView

it's only a previewer related issue?

Nope. When I'm replacing it with plain DataContext issue remains the same.

@Seekeer if it's an error, please attach full message and stacktrace. If it's an error in the console log, please attach full error message. Ideally, minimal sample project would help.

Because, normally, this kind of code works just fine.
