I am experiencing a very weird problem with the WPF Toolkit Charts in a .NET 4 environment.
Basically, I just want to customize the ToolTip template for ColumnDataPoints. To accomplish that, I copied the default style for a ColumnDataPoint from the toolkit source code (generic.xaml) into my control resources and changed the TooltipService part like this:
<UserControl.Resources>
<Style TargetType="charts:ColumnDataPoint" x:Key="CustomDataPointStyle">
<Setter Property="Background" Value="Orange" />
<Setter Property="BorderBrush" Value="Black" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="IsTabStop" Value="False" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="charts:ColumnDataPoint">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Opacity="0" x:Name="Root">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.1" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="MouseOverHighlight" Storyboard.TargetProperty="Opacity" To="0.6" Duration="0" />
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="SelectionStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.1" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Unselected" />
<VisualState x:Name="Selected">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="SelectionHighlight" Storyboard.TargetProperty="Opacity" To="0.6" Duration="0" />
</Storyboard>
</VisualState>
</VisualStateGroup>
<VisualStateGroup x:Name="RevealStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.5" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Shown">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Root" Storyboard.TargetProperty="Opacity" To="1" Duration="0" />
</Storyboard>
</VisualState>
<VisualState x:Name="Hidden">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="Root" Storyboard.TargetProperty="Opacity" To="0" Duration="0" />
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Grid Background="{TemplateBinding Background}">
<Rectangle>
<Rectangle.Fill>
<LinearGradientBrush>
<GradientStop Color="#77ffffff" Offset="0" />
<GradientStop Color="#00ffffff" Offset="1" />
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<Border BorderBrush="#ccffffff" BorderThickness="1">
<Border BorderBrush="#77ffffff" BorderThickness="1" />
</Border>
<Rectangle x:Name="SelectionHighlight" Fill="Red" Opacity="0" />
<Rectangle x:Name="MouseOverHighlight" Fill="White" Opacity="0" />
</Grid>
<ToolTipService.ToolTip>
<StackPanel>
<ContentControl Content="Custom ToolTip" FontWeight="Bold"/>
<ContentControl Content="{TemplateBinding FormattedDependentValue}"/>
</StackPanel>
</ToolTipService.ToolTip>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Now, the problem is that as soon as I apply my CustomDataPointStyle (even if I don't change anything!), the ColumnSeries doesn't show at all in my chart.
<Grid x:Name="ChartGrid" DataContext="{Binding}">
<charts:Chart x:Name="Chart1" Margin="5,0,0,0"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
Title="{Binding Path=Title}">
<charts:Chart.Axes>
<charts:CategoryAxis Orientation="X" Title="{Binding Path=XAxisTitle}" Location="Bottom" />
<charts:CategoryAxis Orientation="Y" Title="{Binding Path=YAxisTitle}" Location="Right" ShowGridLines="True" />
</charts:Chart.Axes>
<charts:ColumnSeries x:Name="ColumnSeries" Title="{Binding Path=SeriesTitle}"
ItemsSource="{Binding Path=Data}" DataPointStyle="{StaticResource CustomDataPointStyle}"
DependentValueBinding="{Binding Path=Value}" IndependentValueBinding="{Binding Path=Key}">
</charts:ColumnSeries>
</charts:Chart>
results in this:
I guess that I am missing a VisualState or something that actually renders the chart but how can that be, given that I copied(!) the original style? The Toolkit is made for .NET 3.5 and I have to use .NET 4 in my application - could that be the reason?
Oh dear, I found the answer: I replaced the System.Windows.DataVisualization.Toolkit.dll for .NET 3.5 with the 4.0 version of this one and now it's working!
You could also try setting Opacity="1" in your Border style block:
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Opacity="1" x:Name="Root">

I have a basic CollectionView:
<CollectionView x:Name="ItemsList" SelectionMode="Single">
<CollectionView.ItemTemplate>
<DataTemplate>
<Grid HeightRequest="80">
<Label Text="Hello world" VerticalOptions="Center"/>
</Grid>
</DataTemplate>
</CollectionView.ItemTemplate>
</CollectionView>
public MainPage()
{
InitializeComponent();
ItemsList.ItemsSource = new List<string>() { "1", "2", "3", "4" };
}
On Android, when the item is tapped you will get a simple tap effect:
I want to keep this effect. But if I change the background color according to the documentation:
<ContentPage.Resources>
<Style TargetType="Grid">
<Setter Property="VisualStateManager.VisualStateGroups">
<VisualStateGroupList>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="Selected">
<VisualState.Setters>
<Setter Property="BackgroundColor"
Value="LightSkyBlue" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
</VisualStateGroupList>
</Setter>
</Style>
</ContentPage.Resources>
The tap effect disappears. Is there some other way to do this?
You can use the Background instead of using the BackgroundColor and the effect will back.
<Setter Property="Background" Value="LightSkyBlue"/>
I'm using the Windows Phone 8.1 DatePicker
It's displaying the date as month/day/year by default and I can't see any way to change this to the 'correct' way of day/month/year.
This is how I declare the DatePicker
<DatePicker Name="datePicker" HorizontalAlignment="Center" MonthFormat="{}{month.full}"/>
displaying it as
I can see in the linked msdn article that I can use a DateTimeFormatter in conjunction with ComboBox selectors but that's not an option for me.
Is it possible?
To Edit the Template
In Xaml every control has a style which you can manipulate, to change it's look and feel. Controls also inherit from one another, for example a date picker is made up of a button and a content container. And a button is made up of a border and a content container.
To Update the date pickers style.. Right click on the date picker control in visual studio from the Menu click edit template then click edit a copy. For this example you want to edit the style of the button template with in the date picker Template...
You will also need to create a Converter class to used in the template
This answer worked for me

The End Result is ...
I needed to show Date as 'Month Year', I tried some solutions I thought about but they didn't work , searched a little and finally found this question and the answer by StuartSmith.
Based on his answer I came up with similar solution that works around localization issue mentioned in comment by Kubaskista
#StuartSmith It will not work for German localization and probably some other regions due to different data format. btw: any idea why "value" in converter is not possible to convert into DateTime?
1- Define Date Picker in xaml, give it name "FirstDatePicker" and then from Designer edit template then choose edit a copy.
<DatePicker x:Name="FirstDatePicker" VerticalAlignment="Top" Grid.Row="1" Margin="0,12,0,0" CalendarIdentifier="GregorianCalendar" DayVisible="False" Padding="0" Style="{StaticResource DatePickerStyle}" RequestedTheme="Light"/>
2- Right Click on FlyoutButton -> Additional Templates -> Edit Generated Content -> Edit a copy.
3- Inside content template, We will bind directly to Date property of FirstDatePicker and by using of StringFormatConverter you can format the date as you wish and override culture also.
<DataTemplate x:Key="DateFormatTemplate">
<Grid>
<TextBlock x:Name="textBlock" HorizontalAlignment="Left" TextWrapping="Wrap" Text="{Binding Date, ConverterParameter=MMMM yyyy, Converter={StaticResource DateFormatConverter}, ElementName=FirstDatePicker, Mode=OneWay}" VerticalAlignment="Top"/>
</Grid>
</DataTemplate>
4- Add StringFormatConverter to solution, Don't forget to add it to resources section of page.
public class DateFormatConverter : IValueConverter
{
#region IValueConverter Members
public object Convert ( object value, Type targetType, object parameter, string language )
{
if(!(value is DateTime || value is DateTimeOffset) || parameter == null) return value;
if(value is DateTime)
{
var date = (DateTime)value;
return date.ToString(parameter.ToString(), CultureInfo.CurrentCulture);
}
else
{
var date = (DateTimeOffset)value;
return date.ToString(parameter.ToString(), CultureInfo.CurrentCulture);
}
}
public object ConvertBack ( object value, Type targetType, object parameter, string language )
{
throw new NotImplementedException();
}
#endregion
}
Note:You can change 'CultureInfo.CurrentCulture' to new Culture("ar-EG") as example or use language passed in converter.
Finally, Here is what i have in resources section of page
<converters:DateFormatConverter x:Key="DateFormatConverter"/>
<x:Double x:Key="ContentControlFontSize">20.26</x:Double>
<FontWeight x:Key="PhoneButtonFontWeight2">Semibold</FontWeight>
<DataTemplate x:Key="DateFormatTemplate">

Is it possible to hide the data points in the chart control from the WinRT XAML Toolkit from CodePlex? I'm using a LineSeries and only want a line without the dots.
This seems to work. Though I am not yet sure why it makes my lines orange...

<Setter

<Setter

<Setter

</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</charting:LineSeries.DataPointStyle>
</charting:LineSeries>
</charting:Chart>
#Filip Skakun thanks for the very accurate answer, and about your issue regarding Orange Lines try adding this property and change the color to whatever color you want.
<Charting:LineSeries.DataPointStyle>
<Style TargetType="Charting:LineDataPoint">
<Setter Property="Background" Value="Red" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Charting:LineDataPoint">
<Grid x:Name="Root" Opacity="0" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Charting:LineSeries.DataPointStyle>
it happens mainly because Chart's are capable of displaying multiple data series on single chart. and for Series[0] the default color is set to Orange.
Although the comment of the AppBarButtonStyle of the StandardStyles.xaml-ResourceDictionary states, that it can be used for Buttons and ToggleButtons, it does not behave reliable for ToggleButton controls.
Applied to a ToggleButton, the Outline is missing, and in some occasions, the Unchecked-state will be rendered as Checked. Moreover, the style references an Element named "BackgroundCheckedGlyph" which is not defined and leads to debug-errors when used in an AppBar.
Has someone already found or built a working Style for Buttons and ToggleButtons?
There are clearly some issues with StandardStyles.xaml and ToggleButtons in RTM.
While HCL's attempt to fix this is a good start, there are still some issues, by HCL's own admission.
Until this is fixed by MS, I think it's best to use an entirely separate style for ToggleButtons. There is a working Style at this MS forum page which I've reproduced below - so far, it seems to function perfectly.

I've found that if I set the VisualState of the ToggleButton manually then the style works just fine (after adding the missing TextBlock). Not sure why this works (or why it's not working to begin with...)
See this post for more information.
Here the result of my own trials to fix the Style. It seems to work (I have looked at it in the "Light"-theme and in the "HighContrast"- Theme. I have found some minor drawbacks, but it seems to me better than the original.
If I invest more time in this, I will post the improved Version. If you use this Style and improve it yourself, feel free to Change my Version.

I just want to ask for your opinion on how to achieve the 'Slide to Unlock' feature from iPhone using Windows Presentation Foundation.
I already came across to this article: iPhone slide to unlock progress bar (part 1), and wondering if you can give me some other resources for a good head start. Thank you.
I would retemplate a Slider, as this is the closest control, functionality-wise.
You should catch the event of Value_Changed, and if Value == Maximum then the slider is "opened".
Retemplating the control would make it look like your "unlock control" with ease. I'll paste later an example.
-- EDIT --
Have free time at work, so I started it for you.
The usage is as follows:
<Grid x:Name="LayoutRoot">
<Slider Margin="185,193,145,199" Style="{DynamicResource SliderStyle1}"/>
</Grid>

Note that this is a very good start, but it's not everything.
I would also define a custom control that derives from slider and that uses this style automatically. Also I would expose a SlideUnlocked event when the user slides all the way right.
To finish it all i would also add an animation that moves the Thumb back left in case the user has dragged it right, but not all the way (to imitate iPhone's UX exactly.)
Good luck, and ask away if you don't know how to implement any of the stages i suggested.
WPF slider has got one "-" and it is value ,
always when you move it, value is for example in decimal 1,122213174 so one "-".
But another way to create slider is in Windows forms.
Create trackBar1 ,and maximum = 100 points.
This is for Windows forms application:
On trackBar1_mouse_up:
if(trackBar1.Value < 100)
{
//Animation - slide back dynamicaly.
for(int i=0;i<=trackBar1.Value;i++){
int secondVal=trackBar1.Value-i;
trackBar1.Value=secondVal;
System.Threading.Thread.Sleep(15);
}
}
if(trackBar1.Value==100)
{
//sets enabled to false, then after load cannot move it.
trackBar1.Enabled=false;
MessageBox.Show("Done!");
}
And this for WPF Slider: (on PreviewMouseUp)
if (Convert.ToInt16(slider1.Value) < 99)
{
//Animation - slide back dynamicaly.
for (int i = 0; i < Convert.ToInt16(slider1.Value); i++)
{
int secondVal = Convert.ToInt32(slider1.Value) - i;
slider1.Value = secondVal;
System.Threading.Thread.Sleep(10);
if (secondVal < 2)
{
slider1.Value = 0;
}
}
}
if (Convert.ToInt16(slider1.Value) > 99)
{
//sets enabled to false, then after load cannot move it.
slider1.IsEnabled = false;
slider1.Value = 100;
MessageBox.Show("Done!");
}
Good luck! I hope it helps, try it with slider, but I think application will crash.
