How to set StyleClass for MenuItem from AppShell programmatically - c#

I want so create my own MenuItems in the AppShell, this is working for me, but now I want to add StyleClass to this MenuItems. I have a StylClass Resource for MenuItems in the AppShell. If I add a MenuItem in AppShell.xaml I can use it without any problem, but my question is, how to that for my on created MenuItems in the code bind.
AppShell.xaml
<Shell.Resources>
<ResourceDictionary>
<Style Class="MenuItemLayoutStyle" TargetType="Layout" ApplyToDerivedTypes="True">
<Setter Property="VisualStateManager.VisualStateGroups">
<VisualStateGroupList>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal">
<VisualState.Setters>
<Setter TargetName="FlyoutItemLabel" Property="Label.TextColor" Value="{StaticResource Primary}" />
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
</VisualStateGroupList>
</Setter>
</Style>
</ResourceDictionary>
</Shell.Resources>
AppShell.xaml.cs
private static MenuItem CreateMenuItem(string title, ICommand cmd)
{
var menuItem = new MenuItem
{
Text = title,
Command = cmd,
//Set StyleClass here
};
return menuItem;
}
How can I use the StyleClass from the Sheel.Resources in the code behind?
Thanks for you help

Firstly, define one style for Menuitem, like this:
<Style Class="menuitemstyle" TargetType="Label">
<Setter Property="TextColor" Value="Red" />
<Setter Property="HeightRequest" Value="100" />
</Style>
Then add one MenuItem by code behind in AppShell.cs and use style from Shell.Resources.
public AppShell()
{
InitializeComponent();
Items.Add(new MenuItem() { Text="test 1",StyleClass=new[] { "menuitemstyle" } });
}
Finally, you can get the screenshot:

Unhandled exception `The parameter is incorrect` in NotifyCollectionChangedEvent handler

I have a very simple ListView whose ItemsSource is a ObservableCollection. Better show it with code:
MainPage.xaml:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Windows.UI.Xaml.Shapes"
x:Class="Test.MainPage" Background="Black" >
<Grid x:Name="Board" Background="Transparent" >
<ListView ItemsSource="{x:Bind LineList}">
<ListView.ItemTemplate>
<DataTemplate x:DataType="local:Line">
<StackPanel Orientation="Horizontal" Spacing="5">
<TextBlock Foreground="White" Text="{x:Bind Name}"/>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
Mainpage.xaml.cs:
public sealed partial class MainPage : Page
{
public ObservableCollection<Line> LineList = new ObservableCollection<Line>();
public MainPage()
{
InitializeComponent();
LineList.CollectionChanged += List_CollectionChanged;
LineList.Add(new Line { Name = "Line1" });
LineList.Add(new Line { Name = "Line2" });
}
private void List_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
if(e.Action == NotifyCollectionChangedAction.Add)
{
Board.Children.Add(e.NewItems[0] as Line);//if I comment out this line, no exception
}
}
}
What I actually want is that, when I add a Line on the ListView to show it's Name, it be also added in the Grid as an actual Shape. Note that, I am using the ListView only to show the Names of those Lines, and in the Grid I want an actual Line Shape
I don't know what I've done wrong, but the above attempt gives the stated Exception.
If these informations help:
No Exception occurs if I don't add the Line in the Grid
No Exception if : Board.Children.Add(new Line { Name = "Line2" });
I've been fiddling around with your code and I was able to track down what is wrong with your code. However I'm not really sure why it's happening.
The reason why you're getting errors is because you're trying to use same instance of an UIElement (i.e. Line) that you're binding to your ListView.ItemsSource. Why it's failing, is a bit of mystery to me. I suspect that it's forbidden to Bind and add the same UIElement to XAML, as it might create binding loops!? That's just a wild guess though. Anyways...
You shouldn't be using UIElement as the binding context - I can't think of any scenario that you would do such thing. You will be better off by creating a separate model, as per my previous answer (e.g. LineViewModel), and using that as your BindingContext. Your MainPage.xaml.cs code could look like this:
public sealed partial class MainPage : Page
{
public ObservableCollection<LineViewModel> Lines = new ObservableCollection<LineViewModel>();
public MainPage()
{
InitializeComponent();
Lines.CollectionChanged += LinesOnCollectionChanged;
Lines.Add(new LineViewModel { Name = "Line1" });
Lines.Add(new LineViewModel { Name = "Line2" });
}
private void LinesOnCollectionChanged(object sender, NotifyCollectionChangedEventArgs e)
{
if (e.Action == NotifyCollectionChangedAction.Add)
{
MainGrid.Children.Add(new Line()
{
Name = (e.NewItems[0] as LineViewModel)?.Name ?? string.Empty,
Stroke = new SolidColorBrush(Colors.Black),
StrokeThickness = 12,
X1 = 0,
X2 = 10000
});
}
}
}
public class LineViewModel
{
public string Name { get; set; }
}
The MainPage.xaml will stay the same, as per my previous answer
I'm not sure if this is what you're after but here it goes

Note, that instead of using Line I used Border. Also, I needed to override base ListViewItemContainerStyle to set HorizontalContentAlignment and VerticalContentAlignment to Stretch, so that the DataTemplate elements can take up the entire space of the item
The result:

KeyDown Event is triggered twice

I have a style which includes two TextBoxes in order to create a PlaceHolder / Watermark, so far is working fine.The only exception is that the events are triggered twice, the first one comes from the CustomTextBox I have in the Style, and the second one from the CustomTextBox I have in XAML.Is there any way to prevent this behaviour? I have already tried to set IsEnable="False" and ReadOnly="True" but doesn't seems to work.Here the style I use to simulate the Watermark:
<Style x:Key="CustomTextBoxStyle"

<Setter Property="FontFamily"

</utils:CustomTextBox>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Any help would be appreciated. Thanks in advance.
EDIT 1: Code on the CustomTextBox Class for the Event handling
protected override void OnKeyDown(KeyEventArgs e)
{
//Filtering "solution"
if (e.Source is CustomTextBox sourceTextBox && sourceTextBox.Name.Equals("textSource"))
{
return;
}
base.OnKeyDown(e);
if (e.Key == Key.Enter && EnterKeyCommand != null)
{
if (EnterKeyCommand.CanExecute(null))
{
EnterKeyCommand.Execute(null);
}
}
}
EDIT 2:
Use of the CustomTextBox on my UserControl:
<Utils:CustomTextBox Grid.Row="0"
Margin="0,10"
KeyboardViewModel="{Binding Path=MainWindowViewModel.KeyboardViewModel}"
HintText="Patient"
x:Name="Patient"/>
Based on your comment, first it comes from the "test source" and then goes to CustomTextBox means that the KeyDown event is received on first user control and then passed to the second user control.
Can you make sure that you put e.Handled = true in the "test source" to notify that it is handled on the first user control?
"Fixed" filtering the e.Source as sugesstion from #Amol Bavannavar on the comments:
protected override void OnKeyDown(KeyEventArgs e)
{
if (e.Source is CustomTextBox sourceTextBox && sourceTextBox.Name.Equals("textSource"))
{
return;
}
base.OnKeyDown(e);
if (e.Key == Key.Enter && EnterKeyCommand != null)
{
if (EnterKeyCommand.CanExecute(null))
{
EnterKeyCommand.Execute(null);
}
}
}

c# uwp templatebinding and dependency property

In UWP I am trying to change default template of tooltip.
I have managed it, but now I need to set tooltip arrow to point out to the control it belongs to.
My style is defined as this:
<Style TargetType="ToolTip">
<Setter Property="Foreground" Value="White" />
<Setter Property="Background" Value="{ThemeResource SystemControlBackgroundChromeMediumLowBrush}" />
<Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundChromeHighBrush}" />
<Setter Property="BorderThickness" Value="{ThemeResource ToolTipBorderThemeThickness}" />
<Setter Property="FontFamily" Value="Roboto" />
<Setter Property="FontSize" Value="{ThemeResource ToolTipContentThemeFontSize}" />
<Setter Property="Padding" Value="40,40,40,35"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ToolTip">
<Grid Background="Transparent">
<Grid
MinWidth="100"
MinHeight="90"
Height="{TemplateBinding Height}"
Width="{TemplateBinding Width}"
Padding="15"
Background="Transparent">
And so on and on...
But now I am trying to make UserControl bind with TemplateBinding property.
I have created UserControl that have some dependecncy property.
Like this:
public PlacementMode TooltipPlacement
{
get { return (PlacementMode)GetValue(TooltipPlacementProperty); }
set { SetValue(TooltipPlacementProperty, value); CalculateArrowVisibility(); }
}
public static readonly DependencyProperty TooltipPlacementProperty =
DependencyProperty.Register("TooltipPlacement", typeof(PlacementMode), typeof(ArrowDown), null);
CalculateArrowVisibility() is a method that will calculate the arrow location depending on TooltipPlacement.
And that control is in style defined as this:
<local:ArrowDown x:Name="arrow" TooltipPlacement="{TemplateBinding Placement}"/>
But it is not bound, I have tried other TemplateProperties but no luck also.
Where is the problem here?
You are very close excpet the way you delcare the dependency property is wrong.
You should never modify its getter and setter. Instead, call your CalculateArrowVisibility method inside its property changed callback like this -
public PlacementMode TooltipPlacement
{
get => (PlacementMode)GetValue(TooltipPlacementProperty);
set => SetValue(TooltipPlacementProperty, value);
}
public static readonly DependencyProperty TooltipPlacementProperty =
DependencyProperty.Register("TooltipPlacement", typeof(PlacementMode), typeof(ArrowDown),
new PropertyMetadata(null, TooltipPlacementChangedCallback));
private static void TooltipPlacementChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
{
var self = (ArrowDown)d;
self.CalculateArrowVisibility();
}

How to add a background to a textbox cue banner

This question showed me how to add a watermark text to my TextBox. I've tried to implement it in my project, but it replaces the background of my TextBox.
Because my panel has a different color, that panel color is shown through the textbox. How can I set this correctly?
I've tried to set the Background of the Label to white, but that doesn't work because it isn't stretched.
<TextBox>
<TextBox.Style>
<Style TargetType="TextBox" xmlns:sys="clr-namespace:System;assembly=mscorlib">
<Style.Resources>
<VisualBrush x:Key="CueBannerBrush" AlignmentX="Left" AlignmentY="Center" Stretch="Uniform">
<VisualBrush.Visual>
<!-- set the background to white -->
<Label Content="Search" Foreground="LightGray" Background="White"/>
</VisualBrush.Visual>
</VisualBrush>
</Style.Resources>
<Style.Triggers>
<Trigger Property="Text" Value="{x:Static sys:String.Empty}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="Text" Value="{x:Null}">
<Setter Property="Background" Value="{StaticResource CueBannerBrush}" />
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter Property="Background" Value="White" />
</Trigger>
</Style.Triggers>
</Style>
</TextBox.Style>
</TextBox>
This gives the following:
But setting Stretch to Fill gives this result with stretched text:
This might not be the best solution, but if my controls are supposed to behave differently from what they are ment to, I like to create them myself. That way I got full control and know exactly what happens when i do this and that.
class TextBoxWaterMark : TextBox
{
#region Datafields
private string pm_WaterMark = "";
#endregion
#region Constructor
public TextBoxWaterMark()
{
}
#endregion
#region Control events
protected override void OnGotFocus(RoutedEventArgs e)
{
base.OnGotFocus(e);
if ((string)this.Tag != "")
{
this.Foreground = new SolidColorBrush(Colors.Black);
this.Text = "";
}
}
protected override void OnLostFocus(RoutedEventArgs e)
{
base.OnLostFocus(e);
if ((string)this.Tag != "")
{
if (this.Text == "")
{
this.Text = pm_WaterMark;
this.Foreground = new SolidColorBrush(Colors.Gray);
}
}
}
#endregion
#region Public get and set methods
public string WaterMark
{
get { return pm_WaterMark; }
set
{
pm_WaterMark = value;
this.Text = pm_WaterMark;
this.Foreground = new SolidColorBrush(Colors.Gray);
}
}
#endregion
and then in my XAML code i simply add it whereever i want like this.
<Form:TextBoxWaterMark WaterMark="Insert watermark text here" />
Hope this is what you are looking for :P
You can add something behind your textbox :
<StackPanel background="white">
<textbox>
</textbox>
</StackPanel>
I think that the right part of your text box is transparent, am I right ?
I also think that there are better component than a StackPanel to do this.

Visual States and a custom dependency property (MVVM)

I'm stuck trying to add a dependency property to a button. I have several buttons located in my header view and clicking on them changes the content in the ContentControl between different views. All this works great. I want the button that was clicked have a different forecolor than the others and it looks like I need to add a dependency property. I think I have all the pieces in place but can't figure out how to get them all to work together.
I have a string property named ViewState in my viewmodel which changes based upon the button being clicked. The property is changing and I'm calling RaisePropertyChanged when it happens. What do I need to do to bind the additional dependency property? I'm transitioning from the WinForm world and trying to mentally piece it all together but struggling a bit.
Here's what I have so far:
<Style TargetType="{x:Type Button}" x:Key="LocalButtonTemplate">
<Setter Property="Foreground" Value="White" />
<Setter Property="Background" Value="{x:Null}" />
<Setter Property="FontFamily" Value="Segoe UI" />
<Setter Property="FontSize" Value="18" />
<Setter Property="Cursor" Value="Hand" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="outerBorder" Background="{TemplateBinding Background}" Margin="4">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="ViewState">
<VisualState x:Name="Dashboard">

</Storyboard>
</VisualState>
<VisualState x:Name="Normal">

My buttons:
<dxwuii:SplitPanel Margin="0,10,10,10" HorizontalAlignment="Right" Grid.Column="2" ItemSpacing="0" Orientation="Horizontal" ItemSizeMode="AutoSize" >
<Button Command="{Binding SendViewModelNameCommand, Mode=OneTime}" CommandParameter="AccountTablesViewModel" Style="{StaticResource LocalButtonTemplate}">Express Tables</Button>
<Button Command="{Binding SendViewModelNameCommand, Mode=OneTime}" CommandParameter="MappingViewModel" Style="{StaticResource LocalButtonTemplate}">Item Mapping</Button>
<Button Command="{Binding SendViewModelNameCommand, Mode=OneTime}" CommandParameter="ReportsViewModel" Style="{StaticResource LocalButtonTemplate}">Reports</Button>
<Button Command="{Binding SendViewModelNameCommand, Mode=OneTime}" CommandParameter="PostBalancesViewModel" Style="{StaticResource LocalButtonTemplate}">Post Balances</Button>
</dxwuii:SplitPanel>
Dependency Property Class:
namespace MyAppName.Model
{
public class StateManager : DependencyObject
{
public static string GetVisualStateProperty(DependencyObject obj)
{
return (string)obj.GetValue(VisualStatePropertyProperty);
}
public static void SetVisualStateProperty(DependencyObject obj, string value)
{
obj.SetValue(VisualStatePropertyProperty, value);
}
public static readonly DependencyProperty VisualStatePropertyProperty =
DependencyProperty.RegisterAttached(
"VisualStateProperty",
typeof(string),
typeof(StateManager),
new PropertyMetadata((dependencyObject, args) =>
{
var frameworkElement = dependencyObject as FrameworkElement;
if (frameworkElement == null)
return;
VisualStateManager.GoToState(frameworkElement, (string)args.NewValue, true);
}));
}
}
Set Tag and Attached property on your each button as below. Tag value will be the VisualState value to which button should go on click.
<Button Tag="AcountTables" local:StateManager.VisualStateProperty="{Binding YOURVIEWMODELPROPERTY}" Command="{Binding SendViewModelNameCommand, Mode=OneTime}" CommandParameter="AccountTablesViewModel" Style="{StaticResource LocalButtonTemplate}">Express Tables</Button>
Update your AttachedProperty like:
public static readonly DependencyProperty VisualStatePropertyProperty =
DependencyProperty.RegisterAttached(
"VisualStateProperty",
typeof(string),
typeof(StateManager),
new PropertyMetadata((dependencyObject, args) =>
{
var frameworkElement = dependencyObject as FrameworkElement;
if (frameworkElement == null)
return;
if (args.NewValue == frameworkElement.Tag.ToString())
{
VisualStateManager.GoToState(frameworkElement, (string)args.NewValue, true);
}
else
{
VisualStateManager.GoToState(frameworkElement, "Normal", true);
}
}));
