1.I cant set the visual state of my textbox, with my c# code the text shows up but the animation does not run, any ideas, or corrections on my c# code would be helpful for me to understand
below is my xaml:
<ControlTemplate x:Name="instructions_text2" TargetType="TextBox">
<Grid>
<TextBlock TextWrapping="Wrap" TextAlignment="Center" HorizontalAlignment="Center" VerticalAlignment="Center" Text="Press Start and drag!" Foreground="#FFCB1717" FontSize="30" FontFamily="AR DELANEY" />
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CustomGroups">
<VisualState x:Name="Blue">
<Storyboard x:Name="Storyboard1" RepeatBehavior="Forever">
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" >
<DiscreteObjectKeyFrame KeyTime="0">
<DiscreteObjectKeyFrame.Value>
<Visibility>Collapsed</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
<DiscreteObjectKeyFrame KeyTime="0:0:0.2">
<DiscreteObjectKeyFrame.Value>
<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Opacity" >
<EasingDoubleKeyFrame KeyTime="0" Value="1"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:1" Value="1"/>
<EasingDoubleKeyFrame KeyTime="0:0:2" Value="0"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Grid>
</ControlTemplate>
c# code:
TextBox instructions = new TextBox();
instructions.Template = Resources["instructions_text2"] as ControlTemplate;
instructions.Width = playArea.ActualWidth;
instructions.Height = playArea.ActualHeight;
VisualStateManager.GoToState(instructions, "Blue", true);
playArea.Children.Add(instructions);
You are trying to change the visual state of the TextBox before it's ready. In fact you are trying to change the state before it's been added to the visual tree.
Change your code to be:
TextBox instructions = new TextBox();
instructions.Template = Resources["instructions_text2"] as ControlTemplate;
instructions.Width = playArea.ActualWidth;
instructions.Height = playArea.ActualHeight;
instructions.Loaded += Instructions_Loaded;
playArea.Children.Add(instructions);
Then in the Loaded handler you can go to the state you want.
private void Instructions_Loaded(object sender, RoutedEventArgs e)
{
var result = VisualStateManager.GoToState(sender as FrameworkElement, "Blue", true);
}
NOTE: There are two versions of VisualStateManager. The one I used is in the namespace System.Windows and it's GoToState takes a FrameworkElement as the first argument - this is the one used by traditional desktop applications. There's also a VisualStateManager in Windows.UI.Xaml that takes a Control as the first argument - this is the one used by new Windows App programs.
As TextBox is a type of control:
private void Instructions_Loaded(object sender, RoutedEventArgs e)
{
var result = VisualStateManager.GoToState(sender as Control, "Blue", true);
}
should work.
Also the ControlTemplate needs a Key, not a Name *:
<ControlTemplate x:Key="instructions_text2" TargetType="TextBox">
The resources dictionary uses the Key value as it's key, so at the moment you're not finding the resource at all so instructions.Template is null.
* this may only be true for desktop applications
Not sure if am framing the question right. So please bear with me if I'm expecting something absurd. I am building a C#/XAML win10 UWP application following the MVVM pattern.
I've some visual states defined for handling wider screens and also some for running some animations. The problem am facing is that, when the visual state to run the animation is called using the VisualStateManager's GoToState method, the setters effected by the VisualState containing the adaptive triggers are lost.
Here's the sample code:
//Defining my grid here
<Grid x:Name="gridNewDrawing" Margin="4">
<Button x:Name="Confirm" Click="Button_Confirm_Click" Width="180" MaxWidth="220" Height="36" HorizontalAlignment="Left" Style="StaticResource StyleButtonGeneral}"/>
<Button x:Name="Cancel" Click="Button_Cancel_Click" Width="180" MaxWidth="220" Height="36" HorizontalAlignment="Left" Style="StaticResource StyleButtonGeneral}"/>
</Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup>
<VisualState x:Name="WideLayoutTrigger">
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="640" />
</VisualState.StateTriggers>
<VisualState.Setters>
<Setter Target="gridNewDrawing.Margin" Value="16" />
</VisualState.Setters>
</VisualState>
<VisualState x:Name="AnimationState">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="Cancel" Storyboard.TargetProperty="Visibility" Duration="0">
<DiscreteObjectKeyFrame KeyTime="0" Value="Collapsed" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
When the width is above 640px; the margin on the gridNewDrawing switches to 16; but when I explicitly call the animation using
GoToState("AnimationState")
The margin on the grid defaults to 4 once again. Is there any way I can have the changes made by the adaptivetrigger persist when setting other visual styles?
The margin of the grid changes to default again because your VisualState are in same VisualStateGroup. You can set the AnimationState in another VisualStateGroup to maintain changes made by the AdaptiveTrigger.
See the Remarks of VisualStateGroup class.
The set of visual states within each VisualStateGroup should be mutually exclusive in the group. In other words, the control should be using exactly one of the visual states from each of its defined VisualStateGroup groups at all times. Whenever there's a case where a control is intended to be simultaneously in two states, make sure that the two states are in different groups.
So apply the following code should get what you want:
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="WindowStates">
<VisualState x:Name="WideLayoutTrigger">
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="640" />
</VisualState.StateTriggers>
<VisualState.Setters>
<Setter Target="gridNewDrawing.Margin" Value="16" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="OtherStates">
<VisualState x:Name="AnimationState">
<Storyboard>
<ObjectAnimationUsingKeyFrames Duration="0" Storyboard.TargetName="Cancel" Storyboard.TargetProperty="Visibility">
<DiscreteObjectKeyFrame KeyTime="0" Value="Collapsed" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
I try to display a button that shows some text. Every X seconds the button must slide to the left and reappear with a new text inside.
Due to the other object on my page I can't use a popup.
Any ideas on how to do this ?
I already try with a grid, except that I don't find how to slide it.
XAML
<Grid x:Name="PropoCloud" VerticalAlignment="Bottom">
<tut:TutorialAwareButton Name="PropoButton"
Style="{StaticResource tplButtonCloud}"
Command="{Binding CmdCreated}"
BorderThickness="0" VerticalAlignment="Bottom"
HorizontalAlignment="Left" Width="410" Height="200">
<tut:TutorialAwareButton.CommandParameter>
<cmd:NavigationCommandParameter TargetName="QuestionCreatingView"></cmd:NavigationCommandParameter>
</tut:TutorialAwareButton.CommandParameter>
</tut:TutorialAwareButton>
</Grid>
C#
private void SuggestionCycling()
{
if (PropoCloud.Visibility == Visibility.Visible)
{
PropoCloud.Visibility = Visibility.Collapsed;
}
else
{
PropoCloud.Visibility = Visibility.Visible;
}
}
Code that you have posted will only hide and show the control back again, you need to have animation to fly it out and bring it in ... have a look at this Link to understand how animation can do that...
The provided link is not for you to copy, make changes to suit your needs and understand the concept.
This is a functionnal solution :
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="FadeStates">
<VisualState x:Name="FadeOut">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="PropoCloud" Storyboard.TargetProperty="PropoCloud.Opacity" From="1" To="0" Duration="0:0:1"/>
</Storyboard>
</VisualState>
<VisualState x:Name="FadeIn">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="PropoCloud" Storyboard.TargetProperty="PropoCloud.Opacity" From="0" To="1" Duration="0:0:2"/>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
Just add the FadeOut.Storyboard.Begin();and FadeIn.Storyboard.Begin();In your timer cycle.
I am developing a Windows Store app, and I hit a problem with scaling to different screen sizes - namely, 140 and 180%. Everything works perfectly on my computer, which is scaled to 100%, but when I test it on the Surface Pro and on the different simulator options that are not scaled to 100%, it starts acting up. I am pretty sure the problem is with the <VisualStateManager> but that is about as far as I can tell.
The problem only appears in the Snapped state, and what happens is in Landscape mode at 140%, the title sometimes appears and sometimes stays blank. Sometimes, clicking the title works to bring up the menu - even if it is blank, while other times nothing happens. The curious part about it is that somehow whether or not it works depends on the data loaded in the DataFrame frame, so if I change the content of those pages to the same content as a working page, it works. The shorter pages appear to have more problems, but that is the only pattern I can find.
When the screen is scaled to 140% portrait mode, none of the text is visible, but some is still clickable.
When the screen is scaled to 180%, the text is not visible, not is it clickable.

I searched the internet for other people having this problem and found these MSDN pages:
Scaling to Pixel Density
Resizing to Narrow Layouts
Support Multiple Screen Sizes
I have already made all of these changes to the best of my knowledge.
My simplified program is available in files here
My images are available here
I don't think you can have bindings in animations. I'd try two separate TextBlocks that bind to different values and alternate Visibility of these in visual state storyboards if different text is how you want to differentiate between views.
OK, this is absolutely crazy. I solved my problem by removing the margin of -2 on the page:
<Page
x:Name="mainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
x:Class="LearnOneNote.MainPage"
mc:Ignorable="d"
Margin="-2">
becomes:
<Page
x:Name="mainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Everything started working immediately in all scale sizes, although I have a thin white line around my page. Any information on why this did this and how to remove that white line is welcome.
I looked on the internet but I can find this nowhere : I would like to disable the TimeHint popup that shows the current time when entering focus on a TimeUpDown control. Something like : <12:42AM>
There is no TimeHintEnabled property, nor any kind of member that seems to control this. There is a TimeHintContent property, but it is readonly and seems empty at first.
My code is really simple :
<Grid x:Name="LayoutRoot" Background="Transparent">
<toolkit:TimeUpDown Name="timeUpDown1"
Background="White"
Height="22"
MinWidth="55"
HorizontalAlignment="Left"
VerticalAlignment="Top" />
</Grid>
Maybe playing with the Template can do the trick, but I don't know how to do it...
Alright, thanks to Blend I found what I was looking for.
The Template can be easily modified by Blend, this part of the template is needed inside the xaml to hide the TimeHintPopup :
<Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="TimeHintStates">
<VisualState x:Name="TimeHintOpenedUp">
<Storyboard>
<ObjectAnimationUsingKeyFrames BeginTime="00:00:00"
Storyboard.TargetProperty="Visibility"
Storyboard.TargetName="TimeHintVisualElement">
<DiscreteObjectKeyFrame KeyTime="00:00:00" Value="Collapsed"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Grid>
And your TimeUpDown should refer to this template :
<toolkit:TimeUpDown Name="timeUpDown1" Background="White" Height="22" MinWidth="55" HorizontalAlignment="Left" VerticalAlignment="Top" Style="{StaticResource TimeUpDownStyle1}" />
