You can use datagrid template as:

XML

<DataGridTemplateColumn Header="Command">
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <Button Name="cmdCommand" Click="{Binding Command}"
                    Content="Command"/>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn
