[Solved] How to call the ActivateItemReorderForItem method

[Sergio]

Hello, I'm working with a DataBoundListBox and I can't find a way to get the right RadDataBoundListBoxItem instance to pass to the ActivateItemReorderForItem method. Here is a part of my code.

This is the DataTemplate for every element inside my ListBox

<Page.Resources>
        <DataTemplate x:Key="ListBoxItemTemplate">
            <ContentControl Holding="ContentControl_Holding">
                <Grid>
                    <Grid.Resources>
                        <converters:FolderContentConverter x:Key="FolderConverter"/>
                    </Grid.Resources>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="0.2*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <Grid Margin="10">
                        <Canvas Background="{StaticResource PhoneAccentBrush}"/>
                        <Image Source="/Assets/MainUI/folder.png"/>
                    </Grid>
                    <StackPanel Grid.Column="1">
                        <TextBlock Text="{Binding Name}"
                            VerticalAlignment="Center"
                            FontSize="25"
                            FontWeight="SemiLight"/>
                        <TextBlock Text="{Binding FolderContent, Converter={StaticResource FolderConverter}}"
                            VerticalAlignment="Center"
                            Foreground="#FFA0A0A0"
                            FontSize="16"
                            FontWeight="SemiLight"/>
                    </StackPanel>
                </Grid>
            </ContentControl>
        </DataTemplate>

And this is my listBox:

<Primitives:RadDataBoundListBox x:Name="listBox"
                  ItemsSource="{Binding Source}"
                  ItemTap="listBox_ItemTap"
                  Tapped="listBox_Tapped"
                  ItemTemplate="{StaticResource ListBoxItemTemplate}"
                  ItemReorderStateChanged="listBox_ItemReorderStateChanged"/>

My source is an ObservableCollection. How can I pick an element from that collection and enable the itemReorderMode for that element?
I need the IsItemReorderEnabled parameter to be set to False, and I just want to enable that mode for a given item programmaticaly.
That method only accepts a RadDataBoundListBoxItem object, and I don't know how to get that from the actual element I pick from my ObservableCollection.

Thanks in advance :)

Hi Sergio,

You can use the GetContainerForItem method of RadDataBoundListBox. It accepts an object parameter -- an element from your observable collection, and returns a RadDataBoundListBoxItem.

Best regards,

Hello, thank you for your answer!
I didn't see those two methods as they returned a RadVirtualizationDataControlItem, I just realized that a RadDataBoundListBox inherits that class, by bad :D
Thank you again for your help!
