How to bind a button's normal and pressed background image?

How to bind a button's normal and pressed background image? - c#

I've managed to save the button style into my AppSetting class based on this code here Cannot correctly populate ListPicker control with Image and Name
Then I want to bind the button's normal and pressed background images (I've several button styles which the user can select in the settings page).

</Grid>
</ControlTemplate>

</Style>
In particular I would like to bind the following items to their respective uri sources but can't perform 'live' binding.
<Image x:Name="NormalBackground" Source="{Binding ButtonUpSetting, Source={StaticResource AppSettings}}" Stretch="Uniform"/>
<Image x:Name="PressedBackground" Source="{Binding ButtonDownSetting, Source={StaticResource AppSettings}}" Stretch="Uniform"/>
I've also implemented INotifyPropertyChangedin my AppSetting class but the button style is not updated when I returned to the button page.
Update:
The button is only updated when I close and reopen the app. So it can read the values from the settings. But it isn't updated right after I change the setting.
The structure of the pages is like the following:
ButtonPage <> SettingPage <> AppSetting Class
So how do I make sure the ButtonPage "re-read" the settings in AppSetting class after I change them in the SettingPage? I am not sure the INotifyPropertyChanged notifies the ButtonPage because it's in the backstack while I make the changes on the SettingPage.
Setting the DataContext = AppSetting inside ButtonPage OnNavigatedTo event does not make any different.

I've figured it out.
Only define the Datacontext in the code not in XAML so
<Image x:Name="NormalBackground" Source="{Binding ButtonUpSetting}" Stretch="Uniform"/>
<Image x:Name="PressedBackground" Source="{Binding ButtonDownSetting}" Stretch="Uniform"/>
Then
protected override void OnNavigatedTo(NavigationEventArgs e)
{
base.OnNavigatedTo(e);
//Rebind all bindings to update button background images
if (e.NavigationMode == NavigationMode.Back)
{
this.DataContext = null;
this.DataContext = settings;
}

From code: Change ScrollViewer's scrollbars'-style to touch

Touch:
Mouse:
How do I tell the ScrollViewer to start using the touch-style scrollbar from code?
Here's an example:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<ScrollViewer Name="scrollViewer1" HorizontalScrollBarVisibility="Visible" >
<Image Stretch="UniformToFill">
<Image.Source>
<BitmapImage x:Name="bitmapImage1" UriSource="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png"></BitmapImage>
</Image.Source>
</Image>
</ScrollViewer>
</Grid>
And:
public sealed partial class MainPage : Page
{
DispatcherTimer dispatcherTimer1 = new DispatcherTimer { Interval = TimeSpan.FromSeconds(5) };
bool SE;
public MainPage()
{
this.InitializeComponent();
dispatcherTimer1.Tick += DispatcherTimer1_Tick;
dispatcherTimer1.Start();
}
private void DispatcherTimer1_Tick(object sender, object e)
{
if (SE = !SE) bitmapImage1.UriSource = new Uri("https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/se/se-icon.png");
else bitmapImage1.UriSource = new Uri("https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png");
scrollViewer1.ChangeView(SE ? 1 : 0, SE ? 1 : 0, null);
}
}
If you run this (at least on a touch enabled PC) the scrollbars will initially be touch. And if you then move the cursor over it with the mouse, it will change to mouse. and if you then touch it (after the scrollbars have been hidden) it will return to touch.
I want to tell it programmatically to change from one to the other. How can that be done? If the only way is by editing the template - how can that be done without hard coding the template ? Just fixing the detail that needs fixing. To be clear: I want to be able to call a method that will change from one to the other: void ChangeTo(bool mouse) { ... }. (Though, failing that, just forcing the ScrollViewer to always be in one mode, would be somewhat of a workaround.)

Within default template there are 3 VisualStates defined:
NoIndicator,
TouchIndicator and
MouseIndicator
Style of scroller thumb looks different depending on which state is currently set.
To change controls state you can call
VisualStateManager.GoToState(scrollViewer1, "TouchIndicator");
but you would need to manually take care of all events and actions when this state may change.
But if you want to have always TouchIndicator visible then better solution in my opinion would be to implement CustomVisualStateManager, for example:
public class MyVisualStateManager : VisualStateManager
{
protected override bool GoToStateCore(Control control, FrameworkElement templateRoot,
System.String stateName, VisualStateGroup group, VisualState state, System.Boolean useTransitions)
{
switch (stateName)
{
case "NoIndicator":
case "TouchIndicator":
case "MouseIndicator":
base.GoToStateCore(control, templateRoot, "TouchIndicator", group, state, useTransitions);
break;
}
return true;
}
}
Then you need to copy the template from MSDN, set it to your ScrollViewer and put MyVisualStateManager within it:
<Style TargetType="ScrollViewer" x:Key="ScrollStyle">
<Setter Property="HorizontalScrollMode" Value="Auto" />
<Setter Property="VerticalScrollMode" Value="Auto" />
<Setter Property="IsHorizontalRailEnabled" Value="True" />
<Setter Property="IsVerticalRailEnabled" Value="True" />
<Setter Property="IsTabStop" Value="False" />
<Setter Property="ZoomMode" Value="Disabled" />
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="VerticalScrollBarVisibility" Value="Visible" />
<Setter Property="Padding" Value="0" />
<Setter Property="BorderThickness" Value="0" />
<Setter Property="BorderBrush" Value="Transparent" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ScrollViewer">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}">
<VisualStateManager.CustomVisualStateManager>
<local:MyVisualStateManager/>
</VisualStateManager.CustomVisualStateManager>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="ScrollingIndicatorStates">
<VisualStateGroup.Transitions>
<VisualTransition From="MouseIndicator" To="NoIndicator">
<Storyboard>
(... blabla ...)
</Style>
style set:
<ScrollViewer Name="scrollViewer1" Style="{StaticResource ScrollStyle}" HorizontalScrollBarVisibility="Visible">
Now whenever your ScrollViewer state needs to be changed, you are ignoring what exact state it wants, setting TouchIndicator instead.

Windows has two scroller visualizations, which are based on the user's input mode: scroll indicators when using touch or gamepad; and interactive scroll bars for other input devices including mouse, keyboard, and pen.
And in Guidelines for panning, it is declared that
There are two panning display modes based on the input device detected:
Panning indicators for touch.
Scroll bars for other input devices, including mouse, touchpad, keyboard, and stylus.
Note Panning indicators are only visible when the touch contact is within the pannable region. Similarly, the scroll bar is only visible when the mouse cursor, pen/stylus cursor, or keyboard focus is within the scrollable region.
Panning indicators Panning indicators are similar to the scroll box in a scroll bar. They indicate the proportion of displayed content to total pannable area and the relative position of the displayed content in the pannable area.
Note Unlike standard scroll bars, panning indicators are purely informative. They are not exposed to input devices and cannot be manipulated in any way.
So the display mode is based on user's input mode, we can't programmatically change it from one to the other. What we can do is editing ScrollViewer's template so that ScrollViewer will only use one visualization UI.
In the default style, we can find ScrollViewer has three VisualStates: NoIndicator, TouchIndicator and MouseIndicator, which are used to control the display mode. We can change TouchIndicator or MouseIndicator visual state to make the ScrollViewer always in one display mode.
For example, we can replace the Storyboard under "TouchIndicator" VisualState with the Storyboard under "MouseIndicator" VisualState to make the ScrollViewer always in scroll bar mode like:

Once we have these two templates, we can use ScrollViewer.Template property to change the display mode from one to the other like following ( "MouseIndicatorTemplate" and "TouchIndicatorTemplate" are placed in Page.Resources):
void ChangeTo(bool mouse)
{
if (mouse)
{
scrollViewer1.Template = (ControlTemplate)Resources["MouseIndicatorTemplate"];
}
else
{
scrollViewer1.Template = (ControlTemplate)Resources["TouchIndicatorTemplate"];
}
}

I was looking to restore the simple scrollbar behavior one might expect from a WPF app (removing the touch indicator altogether). The example given by #Jay Zuo didn't work, so I created my own. The templates can be viewed at the following repository:

How to change image of listbox item on selection change Wp8

I have to show a listbox which have UI similar as below:
On selection change of list box item I can change the background and foreground of list box item. But i need to change the image also. On selection change the image should change and when i select other item the previous item image should get reset and next selected item image should get change.
Is it possible?
How can I do this?
EDIT 1: the data template I am using for

My problem is strange behavior of my template in my project.
In VS2012 in xaml designer TabControl looks normal. But it's completely opposite in compiled application.
The selection state don't work correctly. In fact it presents only normal vsm state.
I can switch between TabItems content but Selection and Hover (mouseOver) state on tab strip are not changing background and border colors. As I said only normal state of VisualStateManager is working in executed app.
Since we cant debug wpf vsm I cant figured out what causes that problem.
I think it is a problem with VisualSateManager.
For test i used single windows with simple tab control posted below
<TabControl>
<TabItem Header="A">content A</TabItem>
<TabItem Header="B">content B</TabItem>
<TabItem Header="C">content C</TabItem>
</TabControl>
If you know what causes a problem with my app, or you have met with similar situation with controls in wpf pleas help me.

I think that your problem may lie in the VisualStateManager class. Had you looked through this page, then you would have seen the VisualStateManager.GoToState Method. This is the method that you should call to change the current visual state... you didn't show this in any of your code, so I can only assume that you have not called this. From the linked page on MSDN, this method:
Transitions the control between two states. Use this method to transition states on control that has a ControlTemplate.
Additionally, you can find an in-depth description of the VisualStateManager class in the answer to the VisualStateManager — showing mouseover state when control is focused

How to remove highlight of button onclick

When a button is clicked, for a fraction of second it gets highlighted in the theme color set by user for the windwos phone device.What method should be called to over ride this behaviour.I tried using MouseEnter and setting the background as white, but it doesnt work,
System.Windows.Media.SolidColorBrush whiteBrush = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 255, 255));

Add it to page and let me know :)

You have to use Styles. This allows you to use the VisualStateManager and control what your control looks like during any point of display (Normal, Hovered, Pressed, Focused). This article is pretty verbose on the topic.

Do not use click event just use MouseLeftButtonUp and MouseLeftButtonDown event.
when you press button at that time MouseLeftButtonDown event is fire so in this method you an change color of button using
System.Windows.Media.SolidColorBrush whiteBrush = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 255, 255));
signIn.Background = whiteBrush;
And in MouseLeftButtonUp event you can set your normal button color
Hope it will work for you.

Resolve textbox background focus issue

I have a simple problem, but I'm new to Silverlight.
I have a textbox, transparent, but when I got focus, textfield background will come white.
How to solve?

You just need to either edit the "FocusedState" in the VisualStateManager for the Default control template, or provide your own like the one provided below in either a Resource Dictionary or in your UserControl.Resources etc.
Here's how you would apply the Style Template Below to your TextBox Instance
<TextBox Style="{StaticResource YourCustomTextBoxStyle}/>
Here's a Default WP7 TextBox Style Template with the proper place Adjusted...
<Style x:Key="YourCustomTextBoxStyle" TargetType="TextBox">
<Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilyNormal}"/>
<Setter Property="FontSize" Value="{StaticResource PhoneFontSizeMediumLarge}"/>
<Setter Property="Background" Value="{StaticResource PhoneTextBoxBrush}"/>
<Setter Property="Foreground" Value="{StaticResource PhoneTextBoxForegroundBrush}"/>
<Setter Property="BorderBrush" Value="{StaticResource PhoneTextBoxBrush}"/>
<Setter Property="SelectionBackground" Value="{StaticResource PhoneAccentBrush}"/>
<Setter Property="SelectionForeground" Value="{StaticResource PhoneTextBoxSelectionForegroundBrush}"/>
<Setter Property="BorderThickness" Value="{StaticResource PhoneBorderThickness}"/>
<Setter Property="Padding" Value="2"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="TextBox">
<Grid Background="Transparent">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Disabled">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" Storyboard.TargetName="EnabledBorder">

<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility" Storyboard.TargetName="DisabledOrReadonlyBorder">

</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Focused"/> <!-- *** Right here is your culprit, I just ripped out the FocusedState Storyboard so it doesnt do anything when focused. *** -->
<VisualState x:Name="Unfocused"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="EnabledBorder" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Margin="{StaticResource PhoneTouchTargetOverhang}">
<ContentControl x:Name="ContentElement" BorderThickness="0" HorizontalContentAlignment="Stretch" Margin="{StaticResource PhoneTextBoxInnerMargin}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="Stretch"/>
</Border>

</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You can also apply this same template to all your TextBox controls by default utilizing BasedOn Values.
There's other ways of doing this with less but this is a good place to begin learning the fundamentals. Hope it helps.

It was more easily!
private void TextBox1_GotFocus(object sender, RoutedEventArgs e)
{
TextBox tb = (TextBox)sender;
tb.Background = new SolidColorBrush(Colors.Transparent);
tb.BorderBrush = new SolidColorBrush(Colors.Transparent);
tb.SelectionBackground = new SolidColorBrush(Colors.Transparent);
}
private void TextBox1_LostFocus(object sender, RoutedEventArgs e)
{
TextBox tb = (TextBox)sender;
tb.Background = new SolidColorBrush(Colors.Transparent);
tb.BorderBrush = new SolidColorBrush(Colors.Transparent);
tb.SelectionBackground = new SolidColorBrush(Colors.Transparent);
}
and it works wery well!!

What you are describing is a Visual State.
When the Textbox gets focus, it internally triggers a visual state change, which in this case includes a white background.
It looks like you are working in WP7, so there are a couple of places you can start learning about Control Templates, Styles and how to change them.
First have a look at this article about Control Templates.
You will find that anything Silverlight 4 related is relevant.
Second get a copy of Expression Blend for Windows Phone. Start a new WP7 project, drag a TextBox onto your design surface, right click the TextBox and selected Edit Template. Then you will start to see how easy it can be to change said visual states.

Looks like you want a click to edit style. There is a silverlight example with xaml code in the Click-to-edit control - how to do it? post.
