Displaying different types of items in the ListBox in WPF

Question

Is it possible to use different templates for items in the ListBox in WPF basing on type of item?

Say, we have base class:

class BaseItem
{
}

And then two more:

class IntItem : BaseItem
{
     public int I { get; set; }
}

class StringItem : BaseItem
{
     public string S { get; set; }
}

Then, I may build an ObservableCollection of BaseItems and attach to the ListBox. I would like to display the text as a textbox and the integer as a tracker, for instance. Is it possible? If so, how can I do it?

Answer 1

Of course this is possible.

Just define a DataTemplate for each Type in your ListBox Resources:

<DataTemplate DataType="{x:Type IntItem}">
    ....
</DataTemplate>
<DataTemplate DataType="{x:Type StringItem}">
    ....
</DataTemplate>
