  • Thread Locking CollectionViewSource

    - by Robert
    I added an event handler to my code and it broke all access to the CollectionViewSources in the SystemHTA class saying "The calling thread cannot access this object because a different thread owns it". My class was working when "this.systemHTA = new SystemHTA();" was placed outside of the DeviceManager_StateChanged() function. public partial class MainWindow : Window { private DeviceManager DeviceManager = DeviceManager.Instance; public SystemHTA systemHTA; public MainWindow() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { DeviceManager.StateChanged += new EventHandler<DeviceManagerStateChangedEventArgs>(DeviceManager_StateChanged); DeviceManager.Initialize(); } void DeviceManager_StateChanged(object sender, DeviceManagerStateChangedEventArgs e) { if (e.State == DeviceManagerState.Operational) { this.systemHTA = new SystemHTA(); } } private void button1_Click(object sender, RoutedEventArgs e) { this.systemHTA.GetViewSourceTest(); } } public class SystemHTA { private CollectionViewSource _deviceTestSource; public SystemHTA() { _deviceTestSource = new CollectionViewSource(); _deviceTestSource.Source = CreateLoadData<HWController>.ControllerCollection; } public void GetViewSourceTest() { ListCollectionView view = (ListCollectionView)_deviceTestSource.View; //This creates an error saying a thread already owns _deviceTestSource } }

  • DataTriggered animation is triggered only in the first time

    - by Pavel
    I just wanted to create very simple example of DataTriggers and animation. Two checkboxes and Rectangle. Checking the first cb makes the rectangle fade away. (CodeBehind var is true) Checking the second cb makes the rectangle come back. (var is false) App is loading - the rectangle is showing (true) Firs cb is checked by default. I'm checking second cb - rect is dissapearing. It's OK. But when I then check the first cb rect isn't showing up. But checking the second cb still makes rect show up and fade away. here's my xaml and code behind: <StackPanel> <RadioButton IsChecked="True" Checked="RadioButton_Checked"></RadioButton> <RadioButton Checked="RadioButton_Checked_1"></RadioButton> <Rectangle Name="r1" Width="100" Height="300" Fill="Green"> <Rectangle.Style> <Style TargetType="Rectangle"> <Style.Triggers> <DataTrigger Binding="{Binding Active}" Value="True"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:1" /> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> <DataTrigger Binding="{Binding Active}" Value="False"> <DataTrigger.EnterActions> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0" Duration="0:0:1" /> </Storyboard> </BeginStoryboard> </DataTrigger.EnterActions> </DataTrigger> </Style.Triggers> </Style> </Rectangle.Style> </Rectangle> </StackPanel> public bool Active { get { return (bool) GetValue(ActiveProperty); } set { SetValue(ActiveProperty, value); } } public static readonly DependencyProperty ActiveProperty = DependencyProperty.Register("Active", typeof(bool), typeof(MainWindow), new UIPropertyMetadata(false)); private void RadioButton_Checked(object sender, RoutedEventArgs e) { Active = true; } private void RadioButton_Checked_1(object sender, RoutedEventArgs e) { Active = false; }

  • Style Data in a gridview which dynamically generates the columns

    - by Coesy
    I have built a dynamic gridview using the following code grdVariants.Columns.Clear(); int i = 0; foreach (DataColumn column in options.Columns) { grdVariants.Columns.Add(new GridViewColumn { Header = column.ColumnName, DisplayMemberBinding = new Binding(string.Format("[{0}]", i++)) }); } This will dynamically generate my columns at runtime, I then bind the data using lstVariantsGrid.DataContext = options; lstVariantsGrid.Items.Refresh(); This all works great and shows the data in the correct columns etc, the only issue i have is that I can't style the rows like I would in xaml as it is all an unknown quantity until runtime. Can anyone offer some advice on how I might go about doing this? One of the biggest problems I have is that one of the columns needs to display the image rather than just the path which it currently shows, as well as fiddling with fonts and colors etc. Thanks for your time.

  • Scroll a ListBox's VirtualizingStackPanel with buttons

    - by Cen
    I have a Listbox displaying 5 items at a time, horizontally. I want to implement a 'Previous' and 'Next' button that when clicked, will display the previous set of 5, or next set of 5 items. I am not displaying the horizontal scroll bar, as I don't want a user to navigate with that. Is there already some functionality implemented so I can do this, or do I need to write code to calculate what items I'm displaying, etc, in the button's click events? Thanks in advance!

  • lighten background color on button click per binding

    - by one of two
    I want to lighten a buttons background on click. So I did the following: <converter:ColorLightConverter x:Key="colorLightConverter" /> ... <Style BasedOn="{StaticResource default}" TargetType="{x:Type controls:Button}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type controls:Button}"> <ControlTemplate.Triggers> <Trigger Property="IsPressed" Value="True"> <Setter Property="Background"> <Setter.Value> <SolidColorBrush Color="{Binding Path=Background.Color, RelativeSource={RelativeSource TemplatedParent}, Converter={StaticResource colorLightConverter}}" /> </Setter.Value> </Setter> </Trigger> </ControlTemplate.Triggers> <Border Background="{TemplateBinding Background}" BorderBrush="Transparent" BorderThickness="0"> ... </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> The converter: class ColorLightConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { Color color = (Color)value; System.Drawing.Color lightColor = ControlPaint.Light(System.Drawing.Color.FromArgb(color.A, color.R, color.G, color.B)); return Color.FromArgb(lightColor.A, lightColor.R, lightColor.G, lightColor.B); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { throw new NotImplementedException(); } } But the converter isn't called when I click the button. I think there is anything wrong with the binding, but I can't see the error... Can you help me? Maybe I'm completely wrong. What I basically want to do: When clicking the button, take the current background color and lighten it. Not more...

  • 'Auto' option missing for TreeView subclass

    - by Jared
    I've created a custom control that subclasses TreeView. Right now it's completely empty, doesn't override anything. However when I place an instance in the designer the 'Auto' value for the Width and Height fields is no longer available as it is with the default TreeView. What am I missing?

  • Silverlight 3 ArcSegment to always draw circle's

    - by kapaboo
    Hi everyone, Ok, my arcSegment must always draw Circle's. For this reason I calculate the Arc's Width with the following formula: arcXRadius = (4 * Math.Pow(height, 2) + Math.Pow(distanceArcPoints, 2)) / (8 * height); so Arcs.Size = (arcXRadius,height) But seems that the height is scaled down when drawn. I want to add a small Circle to the Arc's middle (highest point) so when you drag it it changes the arc Height but also changes the Width so it will remain a circle. Here's how I calculate the Circle's (highest) point: Point middlePoint = GetMiddlePoint(arcPointA,arcPointB); double arcYRadius = arcSegment.Size.Height; if (arcYRadius <= 0) return middlePoint; double angle = arcSegment.RotationAngle; Point ellinewPoint = new Point(); ellinewPoint.X = Math.Cos((angle + 90) * Math.PI / 180) * arcYRadius + middlePoint.X; ellinewPoint.Y = Math.Sin((angle + 90) * Math.PI / 180) * arcYRadius + middlePoint.Y; Until Arc's.Size.Height Property gets Closer to the Width my Circle is not at the right Point. So maybe someone can give me a hint or tell me what am I doing wrong. Cheers, kapaboo

  • Puzzle - Dynamically change data template control from another data template

    - by Burt
    I have a DataTemplate that contains an Expander with a border in the header. I want the header border to have round corners when collapsed and straight bottom corners when expanded. What would best practice be for achieving this (bonus points for code samples as I am new to XAML)? This is the template that holds the expander: <DataTemplate x:Key="A"> <StackPanel> <Expander Name="ProjectExpander" Header="{Binding .}" HeaderTemplate="{StaticResource B}" > <StackPanel> <Border CornerRadius="0,0,2,2"> This is the expander datatemplate: <DataTemplate x:Key="B"> <Border x:Name="ProjectExpanderHeader" CornerRadius="{Binding local:ItemUserControl.ProjectHeaderBorderRadius, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContentPresenter}}}" Background="{StaticResource ItemGradient}" HorizontalAlignment="{Binding HorizontalAlignment, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ContentPresenter}}, Mode=OneWayToSource}"> <local:ItemContentsUserControl Height="30"/> </Border> </DataTemplate>

  • How to define 'Attached property' as 'SelectedValuePath' in ComboBox?

    - by SpudCZ
    Hi, I have a problem with binding in ComboBox. I'd like to bind ComboBox items to ListView columns and as a selected value return value of attached property defined on the selected column. In example bellow you can see working sample that displays width of selected column. If you try to change SelectedValuePath in ComboBox into (loc:SampleBehavior.SampleValue) you get binding error: BindingExpression path error: '(u:SearchableListView.SearchMemberPath)' property not found on 'object' ''GridViewColumn' <Window x:Class="Problem_Sample1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:loc="clr-namespace:Problem_Sample1" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <DockPanel> <ComboBox DockPanel.Dock="Top" x:Name="combobox" ItemsSource="{Binding Path=View.Columns, ElementName=listview}" DisplayMemberPath="Header" SelectedValuePath="Width"> </ComboBox> <StatusBar DockPanel.Dock="Bottom"> <TextBlock> <TextBlock Text="Selected column (value): " /> <TextBlock Text="{Binding Path=SelectedValue, ElementName=combobox}" /> </TextBlock> </StatusBar> <ListView x:Name="listview"> <ListView.View> <GridView> <GridViewColumn Header="Name" Width="101" loc:SampleBehavior.SampleValue="201" /> <GridViewColumn Header="Surname" Width="102" loc:SampleBehavior.SampleValue="202" /> </GridView> </ListView.View> </ListView> </DockPanel> </Window>   SampleBehavior.cs using System.Windows; using System.Windows.Controls; namespace Problem_Sample1 { public static class SampleBehavior { public static readonly DependencyProperty SampleValueProperty = DependencyProperty.RegisterAttached( "SampleValue", typeof (int), typeof (SampleBehavior)); [AttachedPropertyBrowsableForType(typeof(GridViewColumn))] public static int GetSampleValue(GridViewColumn column) { return (int)column.GetValue(SampleValueProperty); } [AttachedPropertyBrowsableForType(typeof(GridViewColumn))] public static void SetSampleValue(GridViewColumn column, int value) { column.SetValue(SampleValueProperty, value); } } }   Thanks for any help or suggestion.

  • Best method for Binding ComboBox

    - by LnDCobra
    I am going to be developing a large project which will include a large number of ComboBoxes. Most of these combo boxes will be bound to a database field which is a related to another daataset/table. For instance. I have the following 2 tables: Company {CompanyID, CompanyName, MainContact} Contacts {ContactID, ContactName} And when the user clicks to edit a company, A TextBox will be there to edit a company name, but also a ComboBox will be there. The way I am currently doing it is binding the ComboBox to the Contacts dataset, and manually updating the Company MainContact field in code behind. Is there anyway for me to bind the selected item to the Company MainContact field in XAML and the items to the ContactName and eliminate the code behind? Reason for this is when you start making 100's combo boxes all over the application it gets long winded each time creating code behind to do the update.

  • Changing BeginTime stops animation

    - by SaphuA
    Hi, I have a storyboard as a resource in a rectangle with a simple doubleAnimation. <Storyboard x:Name="EffectStoryboard"> <DoubleAnimation From="0" To="500" Storyboard.TargetName="WaveEffect" Storyboard.TargetProperty="Val0" RepeatBehavior="Forever" Duration="01:00:00" /> </Storyboard> I start the storyboard in the loaded event of the rectangle: private void Rectangle_Loaded(object sender, RoutedEventArgs e) { Rectangle rectangle = sender as Rectangle; if (rectangle != null) { Storyboard storyboard = rectangle.Resources["EffectStoryboard"] as Storyboard; //DoubleAnimation doubleAnimation = storyboard.Children[0] as DoubleAnimation; //if (doubleAnimation != null) //{ // doubleAnimation.BeginTime = new TimeSpan(0, random.Next(0, 60), random.Next(0, 60)); //} storyboard.Begin(); } } The problem is that when I uncomment the commented code, the animation won't start anymore. Even when I use non-random values in the timespan. Why?

  • Dynamcally resising an open Accordion

    - by alavers
    I have an Accordion and the height of its content can be dynamically resized. I would like to see the Accordion dynamically respond to the child item's height, but I'm having trouble doing this. <lt:Accordion Name="MyAccordion" SelectionMode="ZeroOrOne" HorizontalAlignment="Stretch"> <lt:AccordionItem Name="MyAccordionItem" Header="MyAccordion" IsSelected="True" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch"> <StackPanel> <Button Content="Grow" Click="Grow"/> <Button Content="Shrink" Click="Shrink"/> <TextBox Name="GrowTextBox" Text="GrowTextBox" Height="400" Background="Green" SizeChanged="GrowTextBox_SizeChanged"/> </StackPanel> </lt:AccordionItem> </lt:Accordion> private void Grow(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height += 100; } private void Shrink(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height -= 100; } private void GrowTextBox_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e) { MyAccordion.UpdateLayout(); MyAccordionItem.UpdateLayout(); } Mind you, if I collapse and then re-open the accordion, it takes shape just the way I want, but I'd like this resizing to occur immediately when the child resizes. I feebly attempted to fix this by adding a SizeChanged event handler that calls UpdateLayout() on the Accordion and AccordionItem, but this doesn't have any visual effect. I can't figure out where proper resizing takes place inside the Accordion control. Does anyone have an idea?

  • Multiple exports with MEF does some really heinous stuff -- why, and why is it allowed?

    - by Dave
    I have an interesting situation where I need to do something like this: [Export[typeof(ICandy1)] [Export[typeof(ICandy2)] public class Candy : ICandy2 { ... } where public interface ICandy1 { ... } public interface ICandy2 : ICandy1 { ... } I couldn't find any posts anywhere regarding using multiple [Export] attributes, so I figured, what the hell, might as well try it. At first glance, it actually seemed to work. I have a couple of methods that call into both interfaces of a Candy instance, and it was fine. However, as I started to test the app, I saw that the behavior wasn't right, and when looking at the Output window, I saw that I was getting tons of COMExceptions. I couldn't track down where they were all coming from, but they always occurred when a worker thread was sleeping. I figured that it had to be from the main thread, then, but didn't know how to debug this at all. Nothing should have been going on in the GUI, and I disabled my DispatchTimers just in case -- same thing. Even more strange than the COMExceptions was the really, really erratic behavior when stepping through code. About 30% of the time, when I single stepped, it would pop out of the method, or it would single step over two lines of code! Totally weird stuff that I am not used to seeing. The only thing that changed between working and non-working code was the introduction of MEF through my plugin loading code. So as a test, I changed my plugin assembly to only export one interface, and I hardcoded everything in the app that relied on the other (now not-implemented) interface. And now the COMExceptions are gone, and the weird debugging behavior is gone. Is this something people here have seen before? If MEF is not expected to allow a class to Export multiple interfaces, then shouldn't a CompositionException get raised when composing the parts? Can anyone explain why MEF would cause these weird problems???

  • How do I determine inactivity in a MVVM application?

    - by Jordan
    I have an MVVM kiosk application that I need to restart when it has been inactive for a set amount of time. I'm using Prism and Unity to facilitate the MVVM pattern. I've got the restarting down and I even know how to handle the timer. What I want to know is how to know when activity, that is any mouse event, has taken occurred. The only way I know how to do that is by subscribing to the preview mouse events of the main window. That breaks MVVM thought, doesn't it? I've thought about exposing my window as an interface that exposes those events to my application, but that would require that the window implement that interface which also seems to break MVVM.

  • Closing a window when it's "no longer needed".

    - by Mason Blier
    This is kind of a hard question to describe, and I've searched for about an hour now to no avail. Essentially, picture a small 'flyout' window like the Windows 7 Wireless Control or the Volume Slider from the system tray(notification area). When you click on the icon, the application pops up with focus, and if you click off of it, the window destroys itself. I thought it woudl be easily solved by simply having my window destroy it self when it loses focus (I've been listening for WM_KILLFOCUS), but the problem is, if the icon is clicked, my window does not always get focus. Since this isn't the case, if the user clicks my icon, and then clicks away because it was a mistake (on the desktop say), then how can I set my app to close? I've tried messing with SPY++ but checking the volume control / wireless control apps are proving difficult as they disappear when I try to get their window/process handles. Thanks!

  • association of more than one model to a listview

    - by Veer
    I have 3 Tables in my database. Each table has 3 fields each, excluding the ID field. out of which 2 fields are of type nvarchar. None of the tables are related. My ListView in the application helps the user to search my database, the search being incremental. The search includes the nvarchar fields of the 3 tables ie, 6 fields in total. Eg: PhoneBook: Name, PhoneNo Notes: Title, Content Bookmarks: Name, url I've the models generated for the 3 tables. Now the ListBox should display the Ph.Name, Title and the Bo.Name fields. ie, It should be bound to them. But they are from different models. I also should be able to perform CRUD operation on the item searched. How would i do that? P.S: Separate ViewModels are created for each Model which are used for their respective views for handling those tables individually. But this is an integrated view where the user should be able to search everything. Also please somebody suggest me a better Title for this question:)

    I have a DrawingBrush as a resource like this: <DrawingBrush x:Key="Calendar" Stretch="Uniform"> <DrawingBrush.Drawing> <DrawingGroup> <DrawingGroup.Children> <GeometryDrawing Geometry="F1 M 28.0917,2.13333C 42.4005,2.13333 54,13.7329 54,28.0417C 54,42.3504 42.4004,53.95 28.0917,53.95C 13.7829,53.95 2.18334,42.3504 2.18334,28.0417C 2.18334,13.7329 13.7829,2.13333 28.0917,2.13333 Z "> <GeometryDrawing.Pen> <Pen Thickness="4" LineJoin="Round" Brush="#FF000000"/> </GeometryDrawing.Pen> </GeometryDrawing> <GeometryDrawing Geometry="F1 M 16.9667,16.7083L 39.7167,16.7083L 39.7167,41.625L 16.9667,41.625L 16.9667,16.7083 Z "> <GeometryDrawing.Pen> <Pen Thickness="2.66667" StartLineCap="Square" EndLineCap="Square" MiterLimit="2.75" Brush="#FF000000"/> </GeometryDrawing.Pen> </GeometryDrawing> <GeometryDrawing Brush="#FF000000" Geometry="F1 M 15.6333,15.9583L 40.7167,15.9583L 40.7167,25.2917L 15.6333,25.2917L 15.6333,15.9583 Z "/> <GeometryDrawing Brush="#FFFFFFFF" Geometry="F1 M 18.2167,11.9583L 22.9667,11.9583L 22.9667,20.875L 18.2167,20.875L 18.2167,11.9583 Z "> <GeometryDrawing.Pen> <Pen Thickness="1.33333" StartLineCap="Square" EndLineCap="Square" MiterLimit="2.75" Brush="#FF000000"/> </GeometryDrawing.Pen> </GeometryDrawing> <GeometryDrawing Brush="#FFFFFFFF" Geometry="F1 M 33.7167,11.925L 38.4667,11.925L 38.4667,20.8417L 33.7167,20.8417L 33.7167,11.925 Z "> <GeometryDrawing.Pen> <Pen Thickness="1.33333" StartLineCap="Square" EndLineCap="Square" MiterLimit="2.75" Brush="#FF000000"/> </GeometryDrawing.Pen> </GeometryDrawing> <GeometryDrawing Brush="#FF000000" Geometry="F1 M 28.0154,36.2658L 28.0154,37.4894L 21.6254,37.4894C 21.6169,37.1934 21.6615,36.908 21.7592,36.6333C 21.915,36.1815 22.165,35.7425 22.5091,35.3162C 22.8533,34.8899 23.3617,34.4091 24.0344,33.8738C 25.0782,32.983 25.776,32.295 26.1279,31.81C 26.4799,31.3249 26.6558,30.8551 26.6558,30.4005C 26.6558,29.9473 26.4894,29.5653 26.1566,29.2544C 25.8238,28.9435 25.3904,28.7881 24.8565,28.7881C 24.2915,28.7881 23.8393,28.9442 23.5001,29.2565C 23.161,29.5688 22.9892,30.0018 22.985,30.5556L 21.7614,30.4196C 21.8449,29.5345 22.1576,28.86 22.6993,28.3962C 23.241,27.9323 23.9686,27.7004 24.882,27.7004C 25.8054,27.7004 26.5358,27.9596 27.0733,28.4779C 27.6107,28.9963 27.8795,29.6385 27.8795,30.4047C 27.8795,30.7942 27.8065,31.1769 27.6607,31.5529C 27.5148,31.9289 27.2726,32.3251 26.9341,32.7415C 26.5957,33.1579 26.0115,33.7215 25.1816,34.4325C 24.4692,35.0216 24.0008,35.4214 23.7763,35.6317C 23.5518,35.842 23.3667,36.0533 23.2208,36.2658L 28.0154,36.2658 Z "/> <GeometryDrawing Brush="#FF000000" Geometry="F1 M 33.3178,37.4894L 33.3178,35.1781L 28.9671,35.1781L 28.9671,33.9545L 33.5897,27.8364L 34.5414,27.8364L 34.5414,33.9545L 35.765,33.9545L 35.765,35.1781L 34.5414,35.1781L 34.5414,37.4894L 33.3178,37.4894 Z M 33.3178,33.9545L 33.3178,30.1774L 30.4648,33.9545L 33.3178,33.9545 Z "/> </DrawingGroup.Children> </DrawingGroup> </DrawingBrush.Drawing> </DrawingBrush> And I can use it like this: <Rectangle Fill="{DynamicResource Calender}" /> Now, my question is: how can I create an attached-property to change all brushes on my resource? e.g. I be able to create this: <Rectangle Fill="{DynamicResource Calendar}" attached:IconHelper.Foreground="Blue" /> on my Rectangle and in my resource, I can get: <DrawingBrush x:Key="Calendar" Stretch="Uniform"> <DrawingBrush.Drawing> <DrawingGroup> <DrawingGroup.Children> <GeometryDrawing Geometry="blah blah"> <GeometryDrawing.Pen> <Pen Brush={attached:ReadItFromAboveRectangle}/> </GeometryDrawing.Pen> </GeometryDrawing> <GeometryDrawing Geometry="blah blah"> <GeometryDrawing.Pen> <Pen Brush={attached:ReadItFromAboveRectangle}/> </GeometryDrawing.Pen> <!-- etc... --> Is there any way to read an attached-property on Rectangle in Calendar resource? Or is there any other way to do this? Thanks in advance.
