How to make (vector) paths selectable in Silverlight, while using MVVM? - c#

I am designing an application in Silverlight with C# and MVVM. On one of the pages I have an image (as in a visual, not the type Image) which is composed of several Path's. In this case they form a face and I would like the user to be able to select several parts (eyes, nose, ears...). Each of these is a separate Path.
The idea is that the user can select one of these vectors and work with it. I'd like the selected one to change color.
I can write a converted of bool to the selected color, that's not a problem. The problem is adding selection logic.
My idea was wrapping it in a ListBox, editing the ItemTemplate to include the Path but this position edthe paths incorrectly. Even after applying margins and the like I couldn't get it properly.
Does anyone have any experience or guidance on this?
Thanks in advance!
ANSWER:
1) Change the ItemsPanel template to your container:
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<Canvas Width="208"
Height="391" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
2) Set the ItemsSource:
The trick here is that positioning/attached attributes only work on the direct children of the ListBox. In this case I am using Canvas.Top and Canvas.Left. The solution is to wrap each Item in an additional ListBoxItem and apply those attributes on the ListBoxItem. (This will happen by default if you dont anyway).
<ListBox>
<ListBoxItem Canvas.Left="10" Canvas.Top="5">
<Path Data="..." Height="200" Width="200" Fill="Black" />
</ListBoxItem>
</ListBox>

Try setting a MouseLeftButtonDown event handler on the Path's that binds to an command on the ViewModel. Should be able to use the sender parameter in the handler to determine which Path to modify.
For the ListBox approach, did you try modifying the ItemsPanel and using a Canvas?

If I understand correctly you could add a VisualStateGroup for FocusStates with a VisualStateManager like you would see on a standard button to apply a different Fill or Border to the path selected. Essentially you'd be making each path behave as a button control would showing a different visual state based on its focus.
(Changed this example to default checkbox template as an example) I can make an example if you need one.
<Style TargetType="CheckBox" x:Key="DefaultCheckBoxStyle">

<TreeViewItem Tag="" Header="Customers" Template="{StaticResource MenuItemNormal}" />
<TreeViewItem Tag="" Header="Setup" Template="{StaticResource MenuItemNormal}" />
</TreeView>
The problem is that now I realize I should have probably overridden the data
template of the tree view item because I want to bind the tree view to a property on my view model. I cannot figure out if I use data template how do I remove the default ugly expander icon that comes with tree view items
Specifically I have 3 questions
Is overriding control template the right way to achieve what I am
trying to do?
How do I bind my tree view to a view model property
instead of hard coding the items?
How do I track the selected item in my view model?
Thank you in advance!

How to change the border around a LoopingSelector

I've been messing around trying to change this red border around the LoopingSelector in code, and in Blend. I just can't figure out how to do it. Here's a picture so you have an idea of what I'm talking about.
<Grid Grid.Row="1" Margin="12,0,12,0" toolkit:TurnstileFeatherEffect.FeatheringIndex="1">
<Grid.Resources>
<DataTemplate x:Key="KiloTemplate">
<Grid Background="DarkBlue">
<TextBlock Text="{Binding}" FontSize="54" FontFamily="{StaticResource PhoneFontFamilySemiBold}" HorizontalAlignment="Center" VerticalAlignment="Center" />
<TextBlock Text="kg" FontSize="24" HorizontalAlignment="Right" VerticalAlignment="Bottom" />
</Grid>
</DataTemplate>
</Grid.Resources>
<toolkitPrimitives:LoopingSelector x:Name="loopingSelectorStarost" Margin="12" Width="128" ItemSize="128,128" ItemTemplate="{StaticResource StarostTemplate}" ManipulationStarted="loopingSelector_ManipulationStarted">
<toolkitPrimitives:LoopingSelector.DataSource>
<local:NumberDataSource Privzeti="18" Minimum="13" Maximum="99" />
</toolkitPrimitives:LoopingSelector.DataSource>
</toolkitPrimitives:LoopingSelector>
</Grid>
EDIT: Here's the soulution, thanks to Chris. W. I copied the style from the Generic.xaml file in the Phone Toolkit samples. I changed the <DiscreteObjectKeyFrame KeyTime="0" Value="Transparent" /> in the Selected Visual State. Here's the code:
<Style TargetType="toolkitPrimitives:LoopingSelectorItem">

Start by finding the template for it, a quick solution search for TargetType="primitives:LoopingSelectorItem" should expose it pretty quick or you could likely get to it in Blend.
Once you have the template you'll just locate the Border or Rectangle object in the template that's causing that border.
However that may not even be necessary if the property is bound to the template already. Can you set something like BorderBrush directly to it? I'd have to load something up to look so I'm just guessing at this point.
Hope this helps.

WP - AutoCompleteBox get list of items with bigger font size

This is my code fo ACB:
<toolkit:AutoCompleteBox x:Name="acbAddress" VerticalAlignment="Top"
ItemsSource="{Binding Source={StaticResource autoCompleteWordList}, Path=ListOfAddresses}"
TextChanged="acbAddress_TextChanged" KeyUp="acbAddress_KeyUp"
Style="{StaticResource AutoCompleteBoxStyle1}"
SelectionChanged="AcbAddress_OnSelectionChanged"/>
And I found this to get Text_OnSelectionChanged working for my cursor to set right position. But now I have popup with very little font size. How can I now set font size for items in popup?

Thanks
You should be able to just give a custom Item style via ItemContainerStyle by targeting the ListBoxItem like;
<Style x:Key="myItemStyle" TargetType="ListBoxItem">
<Setter Property="Background" Value="Khaki" />
<Setter Property="Foreground" Value="DarkSlateGray" />
<Setter Property="Margin" Value="5" />
<Setter Property="FontStyle" Value="Italic" />
<Setter Property="FontSize" Value="14" /><!-- Your Property -->
<Setter Property="BorderBrush" Value="DarkGray" />
</Style>
<toolkit:AutoCompleteBox ItemContainerStyle="{StaticResource myItemStyle}" />
You could also use BasedOn to inherit the rest of the existing style stuff from the default template into your Style so you would only be changing the FontSize
More detailed info found here
Hope this helps.

Change the TextBlock Foreground from ComboBox over Event fire only in a Style.xaml

I have a Style xaml without a .cs File
Below you can find a part of my code. There you can find the TextBlock. I would like to change the fontcolor there when the user takes an action (hover, click, whatever). As you can see there is the VisualStateManager who deals with the events of the Combobox. Is it possible to overwrite the foreground in the Visual state manager (for example: If "click" then red, if "hover" then blue)?
I've spent many time to find a solution for my problem but there is no solution in view...
Can anybody help my? Attention the solution is only in a xaml file implemented that holds all styles from my controls.

WPF: Change background color of border on left mouse button down for mouse click
hei guys.. i could solve it by myself!
the mistake was:
Storyboard.TargetName="Content"... should have been referring to "textBlock" of course....
hope to be helpful for someone else as well...

C# Silverlight - Zoom into Horizontal Listbox Image Items

I have the following listbox below which binds to a database table of image URL's. When the application is running, it is possible to click on each individual image, and witness a light blue selection box appear on the image (you can tell when each individual image is selected as its clicked). What I would like to be able to do is perform a zoom upon clicking each image. Does anyone know of a way in which I could do this by amending the code I am currently using below!? (The reason for this is that I need to display the images in a horizontal listbox, which is what this code does.)
<ListBox x:Name="list1" HorizontalAlignment="Left" RenderTransformOrigin="0.5,0.5" Width="400" d:LayoutOverrides="HorizontalAlignment">

You can access the ListBoxItem control's visualStateManager by overriding the ControlTemplate. In Expression Blend select a ListBoxItem and "Edit a copy" of the Template. This will copy the old ListBoxItem control's style and control template to givey ou a nice starting place to modify what happens on key events that this ListBox control is setup to handle.
After doing this you can apply animations within the visual state manager on a wide variety of events (Hover, Selection, disabled, etc).
If you are data binding your ItemsSource property and don't have literal ListBoxItems to generate a ListBoxItem Style to start from, just create a new ListBox and add a ListBoxItem to it to generate the Style+ControlTemplate from. Once you generate the style, you can change your nice data bound ListBox Item's control template by specifying the newly created resource on your data bound ListBox control's ItemContainerStyle property.
