Hi,

In my application, I've an Listview:

<ContentControl Margin="5,0,5,5" Grid.Row="1" x:Name="MasterPane" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" RenderTransformOrigin="0.5,0.5" Template="{DynamicResource PanelTemplate}">

<ListView x:Name="MasterList" SelectionMode="Single" SelectionChanged="ChangeListViewSelectedItem" Width="Auto" Height="Auto" RenderTransformOrigin="0.5,0.5" ItemsSource="{Binding Mode=Default}" SelectedIndex="-1" Background="{x:Null}" BorderBrush="{x:Null}" Foreground="#FFFFFFFF" IsSynchronizedWithCurrentItem="True">

<ListView.View>

<GridView AllowsColumnReorder="True">

<GridView.ColumnHeaderContainerStyle>

<Style>

<Setter Property="GridViewColumnHeader.Template">

<Setter.Value>

<ControlTemplate TargetType="{x:Type GridViewColumnHeader}">

<Border Style="{StaticResource ListviewHeaderStyle}">

<Button Name="ColumnHeaderSortAndGroupButton" Click="ColumnHeaderSortAndGroupButton_Click" Content="{TemplateBinding GridViewColumnHeader.Content}" VerticalAlignment="Center" HorizontalAlignment="Center" VerticalContentAlignment="Center" Background="Transparent" BorderBrush="Transparent" BorderThickness="0" Foreground="White" />

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

</GridView.ColumnHeaderContainerStyle>

<GridViewColumn Header="Produit" DisplayMemberBinding="{Binding ProductName}" Width="140" />

<GridViewColumn Header="Taille" CellTemplate="{StaticResource ListViewSizeColumn}" Width="50" />

<GridViewColumn x:Name="ImageColumn" Header="Media" CellTemplate="{StaticResource ListViewCheckBoxColumn}" Width="50" />

</GridView>

</ListView.View>

<ListView.GroupStyle>

<GroupStyle HeaderTemplate="{StaticResource GroupHeaderTemplate}" HidesIfEmpty="True" />

</ListView.GroupStyle>

</ListView>

</ContentControl>

With the DataTemplate shown below:

<DataTemplate x:Key="ListViewCheckBoxColumn">

<CheckBox Name="chkOffline" HorizontalAlignment="Center" />

</DataTemplate>

Using VisualTreeHelper on a item of my Listview, I know how I can get the checkbox for this specific item.

But in m case, I would like to get all the item. Indeed, my goal is to implement a "Check All/UnCheck All" part but I don't know how I can change the IsChecked property for each checkbox in my template....

Any ideas ?

Thanks

This blog entry shows how to solve a similar problem: http://www.infusionblogs.com/blogs/jsmith/archive/2006/08/13/720.aspx Specifically, check out the GetCheckBoxFromListBoxItem method.

HTH

Yes, I've already seen that post.

But this is in the case when you want to find the CheckBox in a particular ListView/ListBox item.

In my case, I want to find the CheckBox for all the item so unless doind a boucle (but I hope it will not bad for my application performance), I don't know how I can do.....
