Assign command to a set of buttons in grid through style

Is it possible in silverlight to assign a same command to a set of buttons in a grid through style? or assign it at a common place instead of repeating?

I mean something like using this - 

<Style TargetType="Button">
   <Setter Property="Command" Value="{Binding Command1}"/>
</Style>

instead of -

<Button Command="{Binding Command1}"/> 
<Button Command="{Binding Command1}"/> 
<Button Command="{Binding Command1}"/> 
           ...
<Button Command="{Binding Command1}"/>

What you are looking for is the ItemsControl.

<ItemsControl x:Name="MyItemsControl" ItemsSource="{Binding MyButtonItems}">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <Button Command="{Binding Command1}"/>
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

The Binding will be evaluated against each item, therefore you have several ways of providing the command instance:

  • you could place the same command instance as a public property in each itemInstance
  • you could set a source or relativeSource for the Binding to have it evaluated against the DataContext of the ItemsControl instead of against each item: {Binding Path=DataContext.Command1, ElementName=MyItemsControl}

It is possible. In a simple way you can add a Style to the Resources and use it as a StaticResource. Assuming that Command1 belongs to the ViewModel you are binding to the Window. If not, provide proper path to the Command1 to bind it properly. 

<Window.Resources>
  <Style x:Key="buttonCommandStyle" TargetType="Button">
    <Setter Property="Command" Value="{Binding Path=DataContext.Command1}" />
  </Style>
</Window.Resources>

Then use it as the Style for your Button

<Button Style="{StaticResource buttonCommandStyle}" />
