I have a custom control whose Animation I want to control. I attempt to update this using VisualStateManager.GoToState but it always returns false in Silverlight and the animation never starts. This works perfectly in WPF though with the same XAML.
The Silverlight code
//to start
retval = ExtendedVisualStateManager.GoToElementState(this.canvasParent, "WorkingState", true);
The WPF code
retval = VisualStateManager.GoToElementState(this.canvasParent, "WorkingState", true);
XAML (common):
<Style TargetType="local:WaitSpinner">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:WaitSpinner">
<Viewbox Visibility="{TemplateBinding Visibility}">
<Canvas RenderTransformOrigin="0.5,0.5" x:Name="CanvasParent" Width="120" Height="120">
<!-- other awesomeness -->
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="Working">
<VisualState x:Name="WorkingState">
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="SpinnerRotate"
Storyboard.TargetProperty="Angle"
From="0" To="360" Duration="0:0:01.3"
RepeatBehavior="Forever" />
</Storyboard>
</VisualState>
<VisualState x:Name="Stop"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Canvas>
</Viewbox>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Put <VisualStateManager.VisualStateGroups> on the first ControlTemplate child :
<Style TargetType="local:WaitSpinner">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="local:WaitSpinner">
<Viewbox Visibility="{TemplateBinding Visibility}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="Working">
<VisualState x:Name="WorkingState">
<Storyboard>
<DoubleAnimation
Storyboard.TargetName="SpinnerRotate"
Storyboard.TargetProperty="Angle"
From="0" To="360" Duration="0:0:01.3"
RepeatBehavior="Forever" />
</Storyboard>
</VisualState>
<VisualState x:Name="Stop"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<!-- ................. -->
Edit : (I full response with your comment) Use VisualStateManager GotoState method with this :
VisualStateManager.GoToState(this, "WorkingState", true);

I have the following ListBox, in a Windows Store App project

That uses this style

The ListBox has a biding to
private ObservableCollection<object> indicators = new ObservableCollection<object>();
and this is the type of items the collection contains
public class Indicator
{
public string Image { get; set; }
public Indicator(string image)
{
Image = image;
}
}
what i want is to change the Image field inside the selected item in the ListBox
how can i get this done?
This is what my ListBox Shows, what i want is to have that Green icon, depending on what item is selected
if i clicked item 4 , that item would pass to Green color
wich would mean that the Image field in my Indicator Object that is inside the ListBox at that Index would be updated
I'm using a thumb control in a windows store app to represent a draggable image. However whenever I hover over it it changes into a grey box, and when I drag it it turns into a darker grey box. When release it reverts to the image I gave it as a background. Is there any way to turn off or customize away the highlight/focus and dragging appearances?
EDIT:
Here is my XAML for the control. I have it inside a grid but don't do anything with that.
<Canvas x:Name="PART_background" Background="White" Height="140" Width="20">
<Thumb x:Name="PART_drag" Canvas.Left="0" Width="20" Height="50">
<Thumb.BorderBrush>
<SolidColorBrush Color="Black" Opacity="0"></SolidColorBrush>
</Thumb.BorderBrush>
<Thumb.Background>
<ImageBrush x:Name="PART_image" Stretch="None" AlignmentX="Center" />
</Thumb.Background>
</Thumb>
</Canvas>
You need to edit the template - it works best in Blend, then change the visual state animations. The default template has a few Border elements and for various visual states (PointerPressed, PointerOver) - it animates Opacity of these borders. Here's the extracted template. You can simply remove the Storyboards to get rid of the visual feedback.

I wrote a style for a button to let it rotate a bit when the mouse is over it. Unfortunately the animation does not start.
I have a created a similar style for another button type in my application which uses the VisualStateManager as well and works perfectly well so I don't think it is a problem with the VSM.
Seems there is a problem with the animation but I can't find the issue.
This is what the style looks like:
<Style x:Key="MyButton" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<ContentPresenter Content="{TemplateBinding Content}">
<ContentPresenter.RenderTransform>
<TransformGroup>
<RotateTransform CenterX="0.5" CenterY="0.5" Angle="0" x:Name="content"/>
</TransformGroup>
</ContentPresenter.RenderTransform>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="MouseOverState">
<Storyboard AutoReverse="True" RepeatBehavior="Forever">
<DoubleAnimation From="0" To="10" Duration="0:0:1"
Storyboard.TargetProperty="Angle"
Storyboard.TargetName="content"/>
<DoubleAnimation From="10" To="0" Duration="0:0:1" BeginTime="0:0:1"
Storyboard.TargetProperty="Angle"
Storyboard.TargetName="content"/>
<DoubleAnimation From="0" To="-10" Duration="0:0:1" BeginTime="0:0:2"
Storyboard.TargetProperty="Angle"
Storyboard.TargetName="content"/>
<DoubleAnimation From="-10" To="0" Duration="0:0:1" BeginTime="0:0:3"
Storyboard.TargetProperty="Angle"
Storyboard.TargetName="content"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I have also tried
Storyboard.TargetProperty="(ContentPresenter.RenderTransform).(RotateTransform.Angle)"
You have a few problems with this template:
The VisualStateManager.VisualStateGroups elements needs to be the child of your first FrameworkElement, which in this case is a Grid
The VisualState "MouseOverState" should be renamed "MouseOver"
Each storyboard can animate each dependency property once. You have 4 double animations all attempting to animate the Angle property. What you need to use here is a DoubleAnimationUsingKeyframes that has either LinearDoubleKeyframes or EasingDoubleKeyframes.
Here is a working version of this template:
<Style TargetType="Button" x:Key="MyButton">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="MouseOver">
<Storyboard AutoReverse="True" RepeatBehavior="Forever">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Angle" Storyboard.TargetName="content">
<EasingDoubleKeyFrame KeyTime="0" Value="0" />
<EasingDoubleKeyFrame KeyTime="0:0:1" Value="10"/>
<EasingDoubleKeyFrame KeyTime="0:0:2" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:3" Value="-10"/>
<EasingDoubleKeyFrame KeyTime="0:0:4" Value="0"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter Content="{TemplateBinding Content}">
<ContentPresenter.RenderTransform>
<TransformGroup>
<RotateTransform CenterX="0.5" CenterY="0.5" Angle="0" x:Name="content"/>
</TransformGroup>
</ContentPresenter.RenderTransform>
</ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I'm creating a button using a spritesheet in xaml by repositioning the translateX and translateY values of the button.
What I would like to do is change the translateX and translateY value on the state change, I'm sure this is possible in xaml but under blend it would allow me to change those x and y values as it says they are computed values (i don't want those values tweening, just changing upon hover)
Here's the example of the current single state button.
<Button Content="test" HorizontalAlignment="Center" Height="57" VerticalAlignment="Center" Width="294" d:LayoutOverrides="VerticalAlignment">
<Button.Resources>
<Style x:Key="ButtonStyle1" TargetType="Button">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Grid>
<Rectangle x:Name="R" Opacity="1" StrokeThickness="0" Visibility="Visible">
<Rectangle.Fill>
<ImageBrush ImageSource="/Project;component/wp7_buttons.png" Stretch="None" AlignmentX="Left" AlignmentY="Top" >
<ImageBrush.Transform>
<CompositeTransform TranslateX="-558" TranslateY="0"/>
</ImageBrush.Transform>
</ImageBrush>
</Rectangle.Fill>
</Rectangle>
<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Resources>
<Button.Style>
<StaticResource ResourceKey="ButtonStyle1"/>
</Button.Style>
</Button>
How do I do this? I need to be able to bind each state to a property which will include the x and y translate values and also the ImageSource.
you have to work with VisualStates like below
in blend you cand edit a button template copy and you will see all its VisualStates.
so you just have to change Storyboard.TargetName and Storyboard.TargetProperty to match with your ImageBrush CompositeTransform :)
<ControlTemplate TargetType="Button">
<Grid x:Name="Root">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.1" />
<VisualTransition To="Pressed" />
<VisualTransition From="Pressed" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<DoubleAnimation Duration="0" Storyboard.TargetName="PressedElement" Storyboard.TargetProperty="(FrameworkElement.Opacity)" To="0" />
<DoubleAnimation Duration="0" Storyboard.TargetName="MouseOverElement" Storyboard.TargetProperty="(FrameworkElement.Opacity)" To="1" />
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<DoubleAnimation Duration="0" Storyboard.TargetName="NormalElement" Storyboard.TargetProperty="(FrameworkElement.Opacity)" To="0.25" />
<DoubleAnimation Duration="0" Storyboard.TargetName="PressedElement" Storyboard.TargetProperty="(FrameworkElement.Opacity)" To="1" />
I have a style defined for listboxitem in a resource dictionary. I want to use this style in a cs file of listbox :
I am doing the below thing but it gives me null ,CustomListBoxItemStyle is a name of a key given to the style.
public class CustomListBox : ListBox
{
public CustomListBox()
{
this.ItemContainerStyle = Application.Current.Resources["CustomListBoxItemStyle"] as Style;
}
}
There is no xaml for this.
How to achieve this?
I have a style defined for listboxitem in a resource dictionary.
but is that resource dictionary merged into the application's resource dictionary. It doesn't happen automatically you need to include it in the App.xaml like this:-
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="MyResourceDictionary.xaml" />
</ResourceDictionary.MergedDictionaries>
<!-- other resource defined directly in app xaml -->
</ResourceDictionary>
</Application.Resources>
Ok i tried almost every thing but there was no way to get rid of getting the this.ItemContainerStyle = null
So i changed the way of doing , Instead setting the ItemContainerStyle in a customlistbox.cs inherited from Listbox..I removed it from there.
Then where I was using mine custom listbox that was a usercontrol, so there was axaml for it :), hence i defined my ItemContainerStyle in the usercontrol.resource as shown below :
<UserControl.Resources>
<Style x:Key="CustomListBoxItemStyle" TargetType="ChargeEntry:CustomListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ChargeEntry:CustomListBoxItem">
<Grid Background="{TemplateBinding Background}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver">
<Storyboard>
<DoubleAnimation Duration="0" To=".35" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="fillColor"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Disabled">
<Storyboard>
<DoubleAnimation Duration="0" To=".55" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="contentPresenter"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselected"/>
<VisualState x:Name="Selected">
<Storyboard>
<DoubleAnimation Duration="0" To=".75" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="fillColor2"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Focused">
<Storyboard>
<ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetProperty="Visibility" Storyboard.TargetName="FocusVisualElement">
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Unfocused"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Grid HorizontalAlignment="Stretch">
<TextBlock x:Name="txtName" />
</Grid>
<Rectangle x:Name="fillColor" Fill="#FFBADDE9" IsHitTestVisible="False" Opacity="0" RadiusY="1" RadiusX="1"/>
<Rectangle x:Name="fillColor2" Fill="#FFBADDE9" IsHitTestVisible="False" Opacity="0" RadiusY="1" RadiusX="1"/>
<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}"/>
<Rectangle x:Name="FocusVisualElement" RadiusY="1" RadiusX="1" Stroke="#FF6DBDD1" StrokeThickness="1" Visibility="Collapsed"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
and then used it to custom listbox defined inside the usercontrol only..
<CustomListBox x:Name="lstComboBoxResult" ItemContainerStyle="{StaticResource CustomListBoxItemStyle}" />
