using either checkbox or textbox for an enum type

if I have this structure:



public class Parent
{
public string Name{get; set;}
public List<Child> Childs {get; set;}
}

public class Child
{
public string Name{get; set;}
public string Value{get; set;}
public enum ValueType {get; set;}
}

public enum ValueType
{
Int,
Boolean,
String
};

public class ParentFactory
{
public List<Parent> Parents {get; set;}

public ParentFactory()
{
Child child1 = new Child() {Name="Filter1", Value="1", ValueType=ValueType.String};
Child child2 = new Child() {Name="isExecuted", Value="true", ValueType=ValueType.Boolean};
Child child3 = new Child() {Name="Width", Value="10", ValueType=ValueType.Int};

Parent parent1 = new Parent(){Name="Adam", Childs = new List<Child>(){child1, child2}};
Parent parent2 = new Parent(){Name="Kevin", Childs = new List<Child>(){child3}};

Parents = new List<Parent>(){parent1, parent2};
}
}


I want to bind the object: ParentFactory parentFactory = new ParentFactory(); to ItemsControl:



<DockPanel>
<ItemsControl ItemsSource="{Binding Parents}">
</ItemsControl>
</DockPanel>

<Window.Resources>
<DataTemplate DataType="{x:Type Parent}">
<StackPanel Margin="2,2,2,1">
<Expander Header="{Binding Name}">
<ItemsControl ItemsSource="{Binding Childs}" />
</Expander>
</StackPanel>
</DataTemplate>
<DataTemplate DataType="{x:Type Child}">
<StackPanel>
<TextBox Grid.Column="0" Text="{Binding Name}" />
<TextBox Grid.Column="1" Text="{Binding Value}"/>
<TextBox Grid.Column="2" Text="{Binding ValueType}"/>
</StackPanel>
</DataTemplate>
</Window.Resources>


In the Stackpanel, there are one control: TextBox. However, I want it to be more dynamic: if the ValueType is a Boolean then use a Checkbox and else use a Textbox for the: .



Would it be possible? and if yes, how can I achieve them. could you please provide some code samples?
