  • C# function called after dependency property have been set

    - by mizipzor
    My code currently looks like this: private Foo myFoo; public Foo CurrentFoo { get { return myFoo; } set { SetFoo(value); } } private void SetFoo(Foo newFoo) { // Do stuff // Here be dragons myFoo = newFoo; } To be able to bind it in XAML/WPF I need to turn Foo into a dependency property: public static DependencyProperty CurrentFooProperty = DependencyProperty.Register("CurrentFoo", typeof(Foo), typeof(FooHandler), new PropertyMetadata(false)); public Foo CurrentFoo { get { return (Foo)GetValue(CurrentFooProperty); } set { SetValue(CurrentFooProperty, value); } } Ive heard that you shouldnt do magic inside the actual C# property set {}, since it might not be called but the value is written directly to the dependency property. If this is false, let me know, it seems like the most obvious and simple route to take. I know I can add a validation function to the dependency property but I assume that it shouldnt be used for this? I need to communicate the change to legacy systems that cannot yet be bound in XAML. Whats the best way to approach this problem?

  • Use AttachedProperty in Style in ControlTemplate

    - by Andrey
    Here is my simple app: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:app="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Window.Resources> <Style x:Key="Test"> <Setter Property="Button.Template"> <Setter.Value> <ControlTemplate> <Border BorderBrush="Blue" BorderThickness="3" Background="Black" CornerRadius="{Binding app:Extras.CornerRadius}" > </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <Grid> <Button Height="23" HorizontalAlignment="Left" Margin="29,26,0,0" Name="button1" VerticalAlignment="Top" Width="75" app:Extras.CornerRadius="10" Style="{StaticResource Test}" >Button</Button> </Grid> </Window> Here is my AttachedPropery: namespace WpfApplication1 { public class Extras { public static readonly DependencyProperty CornerRadiusProperty = DependencyProperty.RegisterAttached( "CornerRadius", typeof(double), typeof(Button), new FrameworkPropertyMetadata(1.0d, FrameworkPropertyMetadataOptions.AffectsRender) ); public static void SetCornerRadius(UIElement element, double value) { element.SetValue(CornerRadiusProperty, value); } public static double GetCornerRadius(UIElement element) { return (double)element.GetValue(CornerRadiusProperty); } } } CornerRadius="{Binding app:Extras.CornerRadius}" this of course doesn't work. so how can I get value from here app:Extras.CornerRadius="10" thanks in advance!

  • WPF binding problem

    - by Lolo
    I've got problem with binding in XAML/WPF. I created Action class witch extends FrameworkElement. Each Action has list of ActionItem. The problem is that the Data/DataContext properties of ActionItem are not set, so they are always null. XAML: <my:Action DataContext="{Binding}"> <my:Action.Items> <my:ActionItem DataContext="{Binding}" Data="{Binding}" /> </my:Action.Items> </my:Action> C#: public class Action : FrameworkElement { public static readonly DependencyProperty ItemsProperty = DependencyProperty.Register("Items", typeof(IList), typeof(Action), new PropertyMetadata(null, null), null); public Action() { this.Items = new ArrayList(); this.DataContextChanged += (s, e) => MessageBox.Show("Action.DataContext"); } public IList Items { get { return (IList)this.GetValue(ItemsProperty); } set { this.SetValue(ItemsProperty, value); } } } public class ActionItem : FrameworkElement { public static readonly DependencyProperty DataProperty = DependencyProperty.Register("Data", typeof(object), typeof(ActionItem), new PropertyMetadata( null, null, (d, v) => { if (v != null) MessageBox.Show("ActionItem.Data is not null"); return v; } ), null ); public object Data { get { return this.GetValue(DataProperty); } set { this.SetValue(DataProperty, value); } } public ActionItem() { this.DataContextChanged += (s, e) => MessageBox.Show("ActionItem.DataContext"); } } Any ideas?

  • Silverlight with using of DependencyProperty and ControlTemplate

    - by Taras
    Hello everyone, I'm starting to study Silverlight 3 and Visual Studio 2008. I've been trying to create Windows sidebar gadget with button controls that look like circles (I have couple of "roundish" png images). The behavior, I want, is the following: when the mouse hovers over the image it gets larger a bit. When we click on it, then it goes down and up. When we leave the button's image it becomes normal sized again. Cause I'm going to have couple of such controls I decided to implement custom control: like a button but with image and no content text. My problem is that I'm not able to set my custom properties in my template and style. What am I doing wrong? My teamplate control with three additional properties: namespace SilverlightGadgetDocked { public class ActionButton : Button { /// <summary> /// Gets or sets the image source of the button. /// </summary> public String ImageSource { get { return (String)GetValue(ImageSourceProperty); } set { SetValue(ImageSourceProperty, value); } } /// <summary> /// Gets or sets the ratio that is applied to the button's size /// when the mouse control is over the control. /// </summary> public Double ActiveRatio { get { return (Double)GetValue(ActiveRatioProperty); } set { SetValue(ActiveRatioProperty, value); } } /// <summary> /// Gets or sets the offset - the amount of pixels the button /// is shifted when the the mouse control is over the control. /// </summary> public Double ActiveOffset { get { return (Double)GetValue(ActiveOffsetProperty); } set { SetValue(ActiveOffsetProperty, value); } } public static readonly DependencyProperty ImageSourceProperty = DependencyProperty.Register("ImageSource", typeof(String), typeof(ActionButton), new PropertyMetadata(String.Empty)); public static readonly DependencyProperty ActiveRatioProperty = DependencyProperty.Register("ActiveRatio", typeof(Double), typeof(ActionButton), new PropertyMetadata(1.0)); public static readonly DependencyProperty ActiveOffsetProperty = DependencyProperty.Register("ActiveOffset", typeof(Double), typeof(ActionButton), new PropertyMetadata(0)); public ActionButton() { this.DefaultStyleKey = typeof(ActionButton); } } } And XAML with styles: <UserControl x:Class="SilverlightGadgetDocked.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:SilverlightGadgetDocked="clr-namespace:SilverlightGadgetDocked" Width="130" Height="150" SizeChanged="UserControl_SizeChanged" MouseEnter="UserControl_MouseEnter" MouseLeave="UserControl_MouseLeave"> <Canvas> <Canvas.Resources> <Style x:Name="ActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="SilverlightGadgetDocked:ActionButton"> <Grid> <Image Source="{TemplateBinding ImageSource}" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style x:Key="DockedActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource ActionButtonStyle}"> <Setter Property="Canvas.ZIndex" Value="2"/> <Setter Property="Canvas.Top" Value="10"/> <Setter Property="Width" Value="30"/> <Setter Property="Height" Value="30"/> <Setter Property="ActiveRatio" Value="1.15"/> <Setter Property="ActiveOffset" Value="5"/> </Style> <Style x:Key="InfoActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_info.png"/> </Style> <Style x:Key="ReadActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_read.png"/> </Style> <Style x:Key="WriteActionButtonStyle" TargetType="SilverlightGadgetDocked:ActionButton" BasedOn="{StaticResource DockedActionButtonStyle}"> <Setter Property="ImageSource" Value="images/action_button_write.png"/> </Style> </Canvas.Resources> <StackPanel> <Image Source="images/background_docked.png" Stretch="None"/> <TextBlock Foreground="White" MaxWidth="130" HorizontalAlignment="Right" VerticalAlignment="Top" Padding="0,0,5,0" Text="Name" FontSize="13"/> </StackPanel> <SilverlightGadgetDocked:ActionButton Canvas.Left="15" Style="{StaticResource InfoActionButtonStyle}" MouseLeftButtonDown="imgActionInfo_MouseLeftButtonDown"/> <SilverlightGadgetDocked:ActionButton Canvas.Left="45" Style="{StaticResource ReadActionButtonStyle}" MouseLeftButtonDown="imgActionRead_MouseLeftButtonDown"/> <SilverlightGadgetDocked:ActionButton Canvas.Left="75" Style="{StaticResource WriteAtionButtonStyle}" MouseLeftButtonDown="imgActionWrite_MouseLeftButtonDown"/> </Canvas> </UserControl> And Visual Studio reports that "Invalid attribute value ActiveRatio for property Property" in line 27 <Setter Property="ActiveRatio" Value="1.15"/> VERY BIG THANKS!!!

  • Adding data (not only text) to a multi column ListView (WPF)

    - by user811804
    I am working on a WPF application in C# (.NET 4.0) where I have a ListView with a GridView that has two columns. I dynamically want to add rows (in code). My dilemma is that only the first column will have regular text added to it. The second column will have an object that includes a multi column Grid with TextBlocks. (see link http://imageshack.us/photo/my-images/803/listview.png/) If I do what you would normally do when you want to enter text in all columns (ie. DisplayMemberBinding) all I get in the second column is the text "System.Windows.Grid", which obviously isn't what I want. For reference if I just try to add the Grid object (with the TextBlocks) with the code listView1.Items.Add(grid1) (not using DisplayMemberBinding) the object gets added to the second column only (with the first column being blank) and not how it normally works with text where the same text ends up in all columns. I hope my question is detailed enough and any help with this would be much appreciated. EDIT: I have tried the following code, howeever every time I click the button to add a new row every single row gets updated with the same datatemplate. (ie. the second column always shows the same data on every row.) xaml: <Window x:Class="TEST.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="AAA" Title="MainWindow" Height="350" Width="525" Loaded="Window_Loaded"> <Grid Name="grid1"> <Grid.ColumnDefinitions> <ColumnDefinition Width="374*" /> <ColumnDefinition Width="129*" /> </Grid.ColumnDefinitions> <Button Content="Button" Height="23" HorizontalAlignment="Left" Margin="21,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Grid.Column="1" Click="button1_Click" /> </Grid> code: public partial class MainWindow : Window { ListView listView1 = new ListView(); GridViewColumn viewCol2 = new GridViewColumn(); public MainWindow() { InitializeComponent(); Style style = new Style(typeof(ListViewItem)); style.Setters.Add(new Setter(ListViewItem.HorizontalContentAlignmentProperty, HorizontalAlignment.Stretch)); listView1.ItemContainerStyle = style; GridView gridView1 = new GridView(); listView1.View = gridView1; GridViewColumn viewCol1 = new GridViewColumn(); viewCol1.Header = "Option"; gridView1.Columns.Add(viewCol1); viewCol2.Header = "Value"; gridView1.Columns.Add(viewCol2); grid1.Children.Add(listView1); viewCol1.DisplayMemberBinding = new Binding("Option"); } private void Window_Loaded(object sender, RoutedEventArgs e) { } private void button1_Click(object sender, RoutedEventArgs e) { DataTemplate dataTemplate = new DataTemplate(); FrameworkElementFactory spFactory = new FrameworkElementFactory(typeof(Grid)); Random random = new Random(); int cols = random.Next(1, 6); int full = 100; for (int i = 0; i < cols; i++) { FrameworkElementFactory col1 = new FrameworkElementFactory(typeof(ColumnDefinition)); int partWidth = random.Next(0, full); full -= partWidth; col1.SetValue(ColumnDefinition.WidthProperty, new GridLength(partWidth, GridUnitType.Star)); spFactory.AppendChild(col1); } if (full > 0) { FrameworkElementFactory col1 = new FrameworkElementFactory(typeof(ColumnDefinition)); col1.SetValue(ColumnDefinition.WidthProperty, new GridLength(full, GridUnitType.Star)); spFactory.AppendChild(col1); } for (int i = 0; i < cols; i++) { FrameworkElementFactory text1 = new FrameworkElementFactory(typeof(TextBlock)); SolidColorBrush sb1 = new SolidColorBrush(); switch (i) { case 0: sb1.Color = Colors.Blue; break; case 1: sb1.Color = Colors.Red; break; case 2: sb1.Color = Colors.Yellow; break; case 3: sb1.Color = Colors.Green; break; case 4: sb1.Color = Colors.Purple; break; case 5: sb1.Color = Colors.Pink; break; case 6: sb1.Color = Colors.Brown; break; } text1.SetValue(TextBlock.BackgroundProperty, sb1); text1.SetValue(Grid.ColumnProperty, i); spFactory.AppendChild(text1); } if (full > 0) { FrameworkElementFactory text1 = new FrameworkElementFactory(typeof(TextBlock)); SolidColorBrush sb1 = new SolidColorBrush(Colors.Black); text1.SetValue(TextBlock.BackgroundProperty, sb1); text1.SetValue(Grid.ColumnProperty, cols); spFactory.AppendChild(text1); } dataTemplate.VisualTree = spFactory; viewCol2.CellTemplate = dataTemplate; int rows = listView1.Items.Count + 1; listView1.Items.Add(new { Option = "Row " + rows }); } }

  • WPF Binding to change fill color of ellipse

    - by user294382
    Probably a simple question but: How do I programmatically change the color of an ellipse that is defined in XAML based on a variable? Everything I've read on binding is based on collections and lists -can't I set it simply (and literally) based on the value of a string variable? string color = "red" color = "#FF0000"

  • WPF: TextBox expanding with surrounding Grid but not with text

    - by haagel
    I have a problem with a TextBox in an application... A window has a Grid with two columns. The left column contains a control with a constant width but with a height that adapts. The right column contains a TextBox that takes up all remaining space in the Grid (and thereby in the Window). The Grid is given a minimal width and height and is wrapped within a ScrollViewer. If the user resizes the window to be smaller than the minimal widht/height of the Grid, scrollbars are displayed. This is exactly how I want it to be. However, a problem occurs when the user starts typing text. If the text is to long to fit in one line in the TextBox, I want the text to wrap. Therefore I set TextWrapping="Wrap" on the TextBox. But since the TextBox has an automatic width and is wrapped in a ScrollViewer (its actually the whole Grid that is wrapped), the TextBox just keeps expanding to the right. I do want the TextBox to expand if the window is expanded, but I don't want the TextBox to expand by the text. Rather the text should wrap inside the available TextBox. If the text don't fit within the TextBox height, a scrollbar should be displayed within the TextBox. Is there a way to accomplish this? Below is some code that shows my problem. <Window x:Class="AdaptingTextBoxes.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="400" Background="DarkCyan"> <Grid Margin="10" Name="LayoutRoot"> <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto"> <Grid MinWidth="300" MinHeight="200"> <Grid.ColumnDefinitions> <ColumnDefinition Width="auto" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Button Grid.Column="0" Margin="0,0,10,0" Content="Button" Width="100" /> <TextBox Grid.Column="1" AcceptsReturn="True" TextWrapping="Wrap" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Auto" /> </Grid> </ScrollViewer> </Grid> </Window>

  • Nested AccordionItem. Inner AccordionItem do not expand.

    - by Ali
    In Silverlight an AccordionItem is inside another one . When the inner one is selected, it can not expand its parent more which is already expanded to show its own content. I tried to get around it by templating but I was unlucky.

  • WPF TextBox SpellChecking Problem

    - by Alex
    How can I change the spellchecking language of a WPF textbox to french using XAML? I tried this but it doesn't work. <TextBox AcceptsReturn="true" SpellCheck.IsEnabled="true" FontSize="12" BorderBrush="Blue" Height="100" Language="fr-fr" /> French is supposed to be one of the 4 supported languages for spellchecking in WPF so I don't understand why it doesn't work. I also tried fr-CA but it still won't work.

    - by Jobi Joy
    The default DataBinding on TextBox is TwoWay and it commits the text to the Property only when TextBox lost its focus. Is there any easy XAML way exists to make the DataBinding Happens when I press Enter Key on the TextBox?. I know it is pretty easy to do in the code behind, but imagine if this textBox is inside some complex DataTemplate.

  • Preventing a WPF Expander from expanding when header is clicked

    - by emddudley
    How can I prevent a WPF Expander from expanding when its header is clicked? I would like my Expander to expand or collapse only when the expand button itself is clicked. I imagine the answer has something to do with canceling a bubbled event. If possible I would like to implement the solution in XAML while avoiding retemplating the entire Expander.

  • How to animate CornerRadius property with four distinct values - "0,0,0,0" to "0,0,10,10" ?

    - by banzai
    Hi all I have to transition the CornerRadius property of a Border from value "0,0,0,0" to value "0,0,10,10" via an animation. This must be done directly in the XAML file w/o using code behind other than a ValueConverter or similar. I think CornerRadius is animatable using an ObjectAnimationUsingKeyFrames - but how to animate just two of the four values of the CornerRadius structure ? Thanks in advance !

  • How are DynamicResources built and their use in contextmenus.

    - by miguel
    Are dynamic resources truly dynamic? If I define a DynamicResource, I realise that an expression is created (where?) that is not translated into a resource until runtime, however, What I do not understans is whether this dynamicresouce, once built, is now "Static" For instance, if I create a context menu via a dynamicresource, are the menuitems which are created at runtime on access then static, even if they are bound? If so, how can i create a dynamic context menu in XAML?

  • Two way binding settings problem.

    - by Jamie
    Hi, I am having a problem using two way binding with a listpicker. I am able to set the value using c# but not in the SelectedItem=".." in xaml. The binding is returning the correct value (and is a value in the listpicker) as i have texted it by assigning the text to a textblock. When the page loads, the binding used on the listpicker causes a System.ArgumentOutOfRangeException The code i am using to set it is: // Update a setting value. If the setting does not exist, add the setting. public bool AddOrUpdateValue(string key, Object value) { bool valueChanged = false; try { // If new value is different, set the new value if (settingsStorage[key] != value) { settingsStorage[key] = value; valueChanged = true; } } catch (KeyNotFoundException) { settingsStorage.Add(key, value); valueChanged = true; } catch (ArgumentException) { settingsStorage.Add(key, value); valueChanged = true; } catch (Exception e) { Console.WriteLine("Exception occured whilst using IsolatedStorageSettings: " + e.ToString()); } return valueChanged; } // Get the current value of the setting, if not found, set the setting to default value. public valueType GetValueOrDefault<valueType>(string key, valueType defaultValue) { valueType value; try { value = (valueType)settingsStorage[key]; } catch (KeyNotFoundException) { value = defaultValue; } catch (ArgumentException) { value = defaultValue; } return value; } public string WeekBeginsSetting { get { return GetValueOrDefault<string>(WeekBeginsSettingKeyName, WeekBeginsSettingDefault); } set { AddOrUpdateValue(WeekBeginsSettingKeyName, value); Save(); } } And in the xaml: <toolkit:ListPicker x:Name="WeekStartDay" Header="Week begins on" SelectedItem="{Binding Source={StaticResource AppSettings}, Path=WeekBeginsSetting, Mode=TwoWay}"> <sys:String>monday</sys:String> <sys:String>sunday</sys:String> </toolkit:ListPicker> The StaticResource AppSettings is a resource from a seperate .cs file. <phone:PhoneApplicationPage.Resources> <local:ApplicationSettings x:Key="AppSettings"></local:ApplicationSettings> </phone:PhoneApplicationPage.Resources> Thanks in advance

The following XAML code does that: <ListView x:Name="listview"> <ListView.View> <GridView> <GridViewColumn Header="Property" DisplayMemberBinding="{Binding Path=Key}" Width="100"/> <!-- <GridViewColumn Header="Value" DisplayMemberBinding="{Binding Path=Value}" Width="250">--> <GridViewColumn Header="Value" Width="250"> <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Path=Value}" Foreground="CornflowerBlue" AutomationProperties.Name={Binding Path="Key"}/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> The one problem I have is that the AutomationProperties.Name property is not being set. I was checking it with the Coded UI Test Builder and the property is empty. The Text and the Foreground property are being set correctly. Question Does anyone know why AutomationProperties.Name is not being set? Additional information Strangly enough, the following XAML code does set the AutomationProperties.Name <ListView x:Name="listview"> <ListView.Resources> <Style TargetType="TextBlock"> <Setter Property="AutomationProperties.Name" Value="{Binding Key}"/> </Style> </ListView.Resources> <ListView.View> <GridView> <GridViewColumn Header="Property" DisplayMemberBinding="{Binding Path=Key}" Width="100"/> <GridViewColumn Header="Value" DisplayMemberBinding="{Binding Path=Value}" Width="250"/> </GridView> </ListView.View> </ListView> The problem here though is that AutomationProperties.Name is being set on all the columns. But I only want it on the second one because otherwise my Coded UI Test code returns the wrong value (that of the first column, instead of that of the second column which I want).

  • Auto showing tips and closing popup when lost focus

    - by darkwindkey
    I have two elements: a TextBox, and a Popup, where the popup contains a tree view to show some tips according to text of TextBox. When the textBox got the KeyDown Event, the KeyDown directly executes pup.IsOpen=true to show the popup tips. However, I also want to show the popup tips when the mouse on clicking the TextBox, and auto closing the popups when the mouse click on any place (besides the TextBox and the TreeView in Popup). I have tried some cases but do not works fine. Case1: Add pup.IsOpen=true; in TextBox.PreviewMouseUp, the popup will stay opening, even if I click any other place in the window. Case2: Add pup.IsOpen=true in TextBox.PreviewMouseDown, the popup tips only shows on keep clicking the Mouse. Case3: Using CheckBox with Binding IsChecked to Popup.IsOpen works fine. but the tips is listed according to the content of the TextBox, therefore the checkbox is not editable for user... Here is my code now: <Window x:Class="popUpTesting.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBox Name="SearchBox" HorizontalAlignment="Center" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Center" KeyDown="SearchBox_KeyDown" PreviewMouseUp="SearchBox_PreviewMouseUp" /> <Popup Placement="Bottom" AllowsTransparency="True" PopupAnimation="Fade" StaysOpen="false" x:Name="pup" PlacementTarget="{Binding ElementName=SearchBox}" IsOpen="False" > <Grid> <TreeView HorizontalAlignment="Left" Height="200" VerticalAlignment="Top" Width="200"> <TreeViewItem Header="A"> <TreeViewItem Header="A1"/> </TreeViewItem> <TreeViewItem Header="B"></TreeViewItem> <TreeViewItem Header="C"></TreeViewItem> <TreeViewItem Header="D"></TreeViewItem> </TreeView> </Grid> </Popup> </Grid> </Window> and the event functions: private void SearchBox_KeyDown(object sender, KeyEventArgs e) { pup.IsOpen = true; } private void SearchBox_PreviewMouseUp(object sender, MouseButtonEventArgs e) { pup.IsOpen = true; }

  • How do I conditionally format a WPF TextBlock?

    - by Scott Ferguson
    I have a WPF TextBlock bound to a string. If that string is empty, I want the TextBlock to display a warning message in another colour. This is easy to do in code, I was wondering if there was a elegant WPF pure XAML solution for it? I have investigated Style Triggers, but the syntax doesn't come naturally to me. Thanks!
