I am experiencing this as well, this is not happening on previous version (pre 0.9.9 ). I manage to enlarge it by setting minWidth and minHeight

    <TextBlock Text="Module Penambahan Produk" FontSize="25" FontStyle="Normal" TextAlignment="Center" ></TextBlock>
  </StackPanel>

  <StackPanel Grid.Row="5" Grid.Column="1" Orientation="Horizontal" Spacing="4" Margin="4, 20,4,4">
    <Button Width="100" Command="{Binding Add}">Simpan</Button>
    <Button Width="100" x:Name="btnCancel" Command="{Binding Cancel}">Batal</Button>

  </StackPanel>

</Grid>

</UserControl> `

below when i fill with control, it behaved like wrapping the content instead obeying designWidth and designHeight

*pardon for my engrish.

I also have the same problem. The preview is too small or too big when using a DataGrid.
