WPF dynamically add rows of TextBoxes to Grid layout

I have a window in WPF which contains a Grid. The Grid initially has one row and a TextBox in that row. When the user clicks a Button, I have to add a row to the grid with another TextBox. While this seems doable, I need to the grid to be scrollable when the rows exceed the height of the grid. (this sort of resembles how you add attach开发者_如何学Pythonments to email. You add one, and then say add one more..and the list goes on). Am I going about this the right way or is there a better way to do this?

Can't answer whether you're going about it the right way as you've not supplied any code.

Here's how I'd do it. My view models:

public class AttachmentInfo : ViewModel
{
    public string Path { get/set omitted }
}

public class EmailInfo : ViewModel
{
    public ICollection<AttachmentInfo> Attachments { get omitted }

    public ICommand AddAttachmentCommand { get omitted }

    // logic for adding attachment simply adds another item to Attachments collection
}

In my view, something like this:

<ScrollViewer>
    <ItemsControl ItemsSource="{Binding Attachments}">
        <ItemsControl.ItemTemplate>
            <DataTemplate>
                <TextBox Text="{Binding Path}"/>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</ScrollViewer>
<Button Command="{Binding AddAttachmentCommand}">Add</Button>
