Hi there

here is what I would like to do. I get a List of objects from a database and bind this list to a ListBox Control. The ListBoxItems consist of a textbox and a button. Here is what I came up with. Up to this point it works as intended. The object has a number of Properties like ID, Name. If I click on the button in the ListBoxItem the Item should be erased from the ListBox and also from the database...

<ListBox x:Name="taglistBox">    
                        <ListBox.ItemContainerStyle>
                            <Style TargetType="{x:Type ListBoxItem}">
                                <Setter Property="HorizontalAlignment" Value="Stretch"/>
                                <Setter Property="Template">
                                    <Setter.Value>
                                        <ControlTemplate TargetType="ListBoxItem">
                                            <ContentPresenter HorizontalAlignment="Stretch"/>
                                        </ControlTemplate>
                                    </Setter.Value>
                                </Setter>
                                <Setter Property="Tag" Value="{Binding TagSelf}"></Setter>
                            </Style>
                        </ListBox.ItemContainerStyle>
                        <ListBox.ItemTemplate>
                            <DataTemplate>
                                <Grid HorizontalAlignment="Stretch">
                                    <Grid.ColumnDefinitions>
                                        <ColumnDefinition Width="Auto"/>
                                        <ColumnDefinition/>
                                    </Grid.ColumnDefinitions>
                                    <Button Grid.Column="0" Name="btTag"  VerticalAlignment="Center"  Click="btTag_Click" HorizontalAlignment="Left">
                                        <Image Width="16" Height="16" Source="/WpfApplication1;component/Resources/104.png"/>
                                    </Button>
                                    <TextBlock Name="tbtagBoxTagItem" Margin="5" Grid.Column="1" Text="{Binding Name}" VerticalAlignment="Center" />                                        
                                 </Grid>
                            </DataTemplate>
                        </ListBox.ItemTemplate>
                    </ListBox>

The Textblock.Text is bound to object.Name and the ListBoxItem.Tag to object.TagSelf (which is just a copy of the object itself).

Now my questions

1. If I click the button in the listboxItem how do I get the listboxitem and the object bound to it back. In order to delete the object from the database I have to retrieve it somehow. I tried something like

   ListBoxItem lbi1 =
   (ListBoxItem)(taglistBox.ItemContainerGenerator.ContainerFromItem(taglistBox.Items.CurrentItem)); ObjectInQuestion t = (ObjectInQuestion) lbi1.Tag;

2. Is there a way to automatically update the contents of the ListBox if the Itemssource changes? Right now I'm achieving that by

   taglistBox.ItemsSource = null;
   taglistBox.ItemsSource = ObjectInQuestion;

I'd appreciate any help you can give :D Thanks in advance
