SilverLight TreeView Databinding

SouthSpawn posted on Sunday, August 09, 2009

I am using a TreeView Control from the SilverLight toolkit.
I have a object that has a child ReadOnlyList property.

Can someone can me some example syntax on how I can bind the parent and child objects to the TreeView.

I tried googling this, but the examples just seem to be over my head at this point.
I am pretty new to XAML.

Any help would be awesome!!!

Hi

Code sample

    xmlns:kitctrls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

....

                <kitctrls:TreeView x:Name="xTreeView"
                    ItemsSource="{Binding Path=Model.VisibleChildren, Source={StaticResource ViewModel}}"
                    Height="Auto" Width="Auto" VerticalAlignment="Stretch" Loaded="xTreeView_Loaded" >

                    <kitctrls:TreeView.ItemTemplate>
                        <kitcmmn:HierarchicalDataTemplate x:Name="TreeViewTemplate" ItemsSource="{Binding Path=VisibleChildren}">
                            <StackPanel Orientation="Horizontal" >
                                <CheckBox IsChecked="{Binding Mode=TwoWay, Path=IsSelected}" Checked="CheckBox_Checked"
                                    Unchecked="CheckBox_Checked" Loaded="Node_Loaded" />
                                <TextBlock Text="{Binding Path=Name}" Margin="5,0" />
                            </StackPanel>
                        </kitcmmn:HierarchicalDataTemplate>
                    </kitctrls:TreeView.ItemTemplate>
                </kitctrls:TreeView>

May I see what's your data model look like?

my BO look like this

factory(ReadOnlyBase) -> contacts(ReadOnlyListBase)

->property1(string) |_ contact1(ReadOnlyBase)

->property2(string) |_contact2(ReadOnlyBase)

-> Products(ReadOnlyListBase)

|_product1(ReadOnlyBase)

|_product2(ReadOnlyBase)

How doI show them on the TreeView control ?
