Is there anyway of consolidating similar data bindings and/or triggers in XAML?

I have a user control that hosts other controls. The way I implemented this is via data templates that define the control that should be associated with a specific view-model. These view-models have similar properties and interaction triggers. Please see XAML snippet below.

The problem with this approach is that I would have to copy-paste the data bindings if I want to support a new view-model. Is there any way of consolidating all similar data bindings and/or triggers into one template? 开发者_开发知识库I don't want to type/copy-paste the same data binding definitions into each control. (Yes, I know, I'm that lazy.)

<UserControl.Resources>   
    <DataTemplate DataType="{x:Type vm:SomeViewModel1}">
        <TextBlock Canvas.Left="{Binding Left}"
                   Canvas.Top="{Binding Top}"
                   RenderTransform="{Binding Transform}"
                   Height="{Binding Height}"
                   Width="{Binding Width}">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseEnter">
                    <cmd:EventToCommand Command="{Binding MouseEnterCommand}"/>
                </i:EventTrigger>
                <i:EventTrigger EventName="MouseLeave">
                    <cmd:EventToCommand Command="{Binding MouseLeaveCommand}"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
        </TextBlock>
    </DataTemplate>

    <DataTemplate DataType="{x:Type vm:SomeViewModel2}">
        <Rectangle Canvas.Left="{Binding Left}"
                   Canvas.Top="{Binding Top}"
                   RenderTransform="{Binding Transform}"
                   Height="{Binding Height}"
                   Width="{Binding Width}">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseEnter">
                    <cmd:EventToCommand Command="{Binding MouseEnterCommand}"/>
                </i:EventTrigger>
                <i:EventTrigger EventName="MouseLeave">
                    <cmd:EventToCommand Command="{Binding MouseLeaveCommand}"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
        </Rectangle>
    </DataTemplate>

    <DataTemplate DataType="{x:Type vm:SomeViewModel3}">
        <Button Canvas.Left="{Binding Left}"
                Canvas.Top="{Binding Top}"
                RenderTransform="{Binding Transform}"
                Height="{Binding Height}"
                Width="{Binding Width}">
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseEnter">
                    <cmd:EventToCommand Command="{Binding MouseEnterCommand}"/>
                </i:EventTrigger>
                <i:EventTrigger EventName="MouseLeave">
                    <cmd:EventToCommand Command="{Binding MouseLeaveCommand}"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
        </Button>
    </DataTemplate>

    <DataTemplate DataType="{x:Type vm:SomeViewModel4}">
       <!-- Do not want copy-paste code here... -->
    </DataTemplate>
</UserControl.Resources>

You can use common style, and put both your properties and triggers (which are also properties) inside this style, look at this StackOverflow question for more details.

What about putting the triggers into a resource and associating them with your controls. Or use a custom base class for your DataTemplates.
