LocationBox question

[Sam]

I am trying to bind the location box in the RADMAP demo to a web service call, I'm getting this error "A value of type 'Location' cannot be added to a collection or dictionary of type 'UIElementCollection'."

Here is the XAML, I get a blue squiggly line under it and it fails when I run it.

<ListBox x:Name="LocationBox" SelectionChanged="LocationBox_SelectionChanged" ItemContainerStyle="{StaticResource lv-ListBoxItem}" Background="Transparent" BorderBrush="Transparent">

                <ListBox.ItemTemplate>
                    <DataTemplate>

                       <StackPanel Orientation="Vertical">


                            <mapNamespace:Location Description="{Binding RepName}"  Latitude="{Binding Latitude}" Longitude="{Binding Longitude}"/>


                        </StackPanel>

                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>

Hi Sam,

You cannot use the Location class inside a DataTemplate as it is not a visual UIElement (as the error correctly suggests). You can set a collection of Location objects as ItemsSource but then you need to either set the ListBox.DisplayMemberPath property or you need to specify a valid DataTemplate (one that contains UIElements).

Also, for general Silverlight questions that are not related to the RadControls suite, you can try the official MS Silverlight forums as well.
