MVVM Light-如何向网格添加（动态）用户控件？

Question

I'm trying to figure out how to add UserControl to the Grid depending on the user's choice.

Short description:

I have ComboBox:

• ItemSource binded to ObservableCollection<Products> ,
• SelectedItem binded to Product .
• Inside the MainPage.xaml I have <Grid>

I have products like: Doors , Lamps , Chairs etc... All of them inherit from Product class.

Looking for a hints/solutions:

I have many UserControls with ViewModels for Products : One for Doors , one for Lamps , one for Chairs .

Depending on user choice I would like to add selected product UserControl to the <Grid>

Example:

• User selects "Chairs" from the Combobox, another ChairsUserControl.xaml will be added to the <Grid>
• User selects "Doors" from the Combobox, another DoorsUserControl.xaml will be added to the <Grid>

and so on... Grid may have many same UserControls (they can repeat).

many thanks for any hints!
