Question

I'm trying to get the listpicker to show a property that is in an iList. When i run the app, what comes up instead is the binding info.. not that property..

Here is the xaml

 <phone:PhoneApplicationPage.Resources>
    <DataTemplate x:Name="lpkItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
    <DataTemplate x:Name="lpkFullItemTemplate">
        <TextBlock Text="{Binding Operation}" />
    </DataTemplate>
</phone:PhoneApplicationPage.Resources>
 <toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="0" 
                        FullModeItemTemplate="{Binding lpkFullItemTemplate}"
             ItemTemplate="{Binding lpkItemTemplate}"
                        Grid.Row="5" 
                        >

and the code behind

        Dim Os As List(Of wsOperation.Operation) = e.Result
    Me.lbOperation.ItemsSource = Os

i'm thinking it is a template error because the number of rows in the list is the number that comes up when i click on the listpicker.. but the property i've asked ("Operation") is not displaying the data. Instead i get ~10 rows of wsOperation.Operation showing up.

thanks shannon

~~~~~~~~~ maybe a little more info will help with a possible solution Here is what the listpicker shows when i run this page

ProcWP.wsOperation.Operation

when i click on the above line.. this is what the listpicker shows 

ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
ProcWP.wsOperation.Operation
Was it helpful?

Solution

the answer to this problem was in the toolkit:ListPicker. I needed to change the {Binding lpkFullItemTemplate} to {StaticResource lpkFullItemTemplate} and same with itemTemplate

so it looks like this now

<toolkit:ListPicker x:Name="lbOperation" Header="Operations"  SelectedIndex="1" 
                        FullModeItemTemplate="{StaticResource lpkFullItemTemplate}"
             ItemTemplate="{StaticResource lpkItemTemplate}"
                        Grid.Row="5" 
                        >
