Binding a command in a datagrid - wpf

Question

I am trying to bind a button withing datagrid to a custom command.
But for some reason, the command dont get executed.
This is the XAML:
<Grid Name="LayoutRoot">
<ListView Name="ListView1"
ItemsSource="{Binding}"
IsSynchronizedWithCurrentItem="True">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.View>
<GridView>
<GridViewColumn Header="ID" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=id,Mode=OneWay}"
Margin="-6,0,-6,0" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Name" Width="100">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=name,Mode=OneWay}"
Margin="-6,0,-6,0" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Path" Width="50">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBox Text="{Binding Path=path,Mode=OneWay}"
Margin="-6,0,-6,0" />
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Update" Width="50">
<GridViewColumn.CellTemplate>
<DataTemplate>
<Button CommandParameter="{Binding id}" Command="{Binding ???????????}" Content="Edit"/>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</Grid>
</Window>
What should I write instead of the ?????????? in order to show a message with the ID.

Answer 1

I think problem is in Cells DataContext. Within DataTemplate it does not see parent context. Try to add your command to Resources and do something like:
<DataTemplate>
<Button CommandParameter="{Binding id}" Command="{StaticResource yourCommand}" Content="Edit"/>
</DataTemplate>

Create a command Inherit from ICommand interface.
public class ShowMessageWithIdCommand : ICommand
{
// Implement it members
}
in your viewmodel:
public ICommand ShowMessageWithIdCommand
{
get{return new ShowMessageWithIdCommand(...);}
}
Then your ????? will be: ShowMessageWithIdCommand
