ItemsOptionListType="CheckList" in new version and some others properties...

[Fabiana]

Hello Support! I installed new version Q2 2010, and I am having problems with my RadTreeListView example. How to change my code to work again?? Thanks!!!



My code:



<UserControl x:Class="SilverlightApplication1.MainPage"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SilverlightApplication1"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        xmlns:nav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
             mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             Height="213" Width="660"
             xmlns:my="clr-namespace:SilverlightApplication1">

    <UserControl.Resources>
    
        
        <telerik:CellTemplate x:Key="firstNameTemplate" >
            <TextBlock Foreground="#284869" Text="{Binding FirstName}" VerticalAlignment="Center"  Margin="2"/>
        </telerik:CellTemplate>

        <telerik:CellTemplate x:Key="lastNameTemplate" >
            <TextBlock Foreground="#284869" Text="{Binding LastName}" VerticalAlignment="Center"  Margin="2"/>
        </telerik:CellTemplate>
       
        <DataTemplate x:Key="itemTemplate">
            <Grid />
        </DataTemplate>

    </UserControl.Resources>
    
    

    <nav:RadTreeListView Background="White" x:Name="RadTreeListViewTest" BorderBrush="#a9a9a9" BorderThickness="1" HorizontalContentAlignment="Center" Width="574" Height="170"
                         IsDragDropEnabled="False" IsDragPreviewEnabled="False" IsDragTooltipEnabled="False"
                         IsEditable="True" SelectionMode="Single"
                         ItemTemplate="{StaticResource itemTemplate}"
                                                    IsSingleExpandPath="False"
                                                    IsExpandOnSingleClickEnabled="True"
                                                    IsLineEnabled="True" IsOptionElementsEnabled="True" ItemsOptionListType="CheckList">

        <nav:RadTreeListView.Columns>

            <nav:RadColumn Header="First Name" PropertyName="FirstName" Width="150" IsEditable="True" CellTemplate="{StaticResource firstNameTemplate}" />

            <nav:RadColumn Header="Last Name" PropertyName="LastName" Width="150" IsEditable="False" CellTemplate="{StaticResource lastNameTemplate}" />

            
        </nav:RadTreeListView.Columns>


    </nav:RadTreeListView>

</UserControl>

Hi Fabiana,

You can check the difference in the two online examples: old one, new one. As a general note you should updated your columns to use GridViewDataColumns instead and also define the hierarchy using table definitions as illustrated in the online example.
