  • Cannot create instance of 'Ribbon'

    - by user354433
    I'm having trouble using the Ribbon control from the Office 2007 RibbonControlsLibrary.dll. It works for most people but not for me. The fault I get is: Cannot create instance of 'Ribbon' defined in assembly 'RibbonControlsLibrary, Version=3.5.31016.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Exception has been thrown by the target of an invocation The problem is probably not with the code since it works for other people. Its the Ribbon class thats causing the problem. If I remove any references to the Ribbon class but keep the references to RibbonWindow I don't get any exceptions. Any help appreciated

  • Why is the binding icon not visible in blend?

    - by Ankit Rathod
    Hello, Why is the binding icon (a small gray icon) not visible in blend for some properties even though they are DependencyProperties? For eg. I dragged a button on my page and dragged a textbox. I want to bind button's content property to textbox's text property. But i can't find the Binding icon in Blend. I know if i type the binding syntax in code it will work just fine. But why is that icon missing? Thanks in advance :)

  • MediaElement not showing in custom 3D class

    - by user3271180
    I'm trying to display a videostream in a Viewport3d. When I add the MediaElement via xaml, the video plays without a problem; even when I add the video as ModelVisual3D in the code-behind, the video works. When I abstract the video into a class, however, the video stops appearing. This happens with both web and local video files. I tried compiling with both x86 and 64 bit. Any way to fix this behaviour? Why is this happening? I have the following viewport: <Viewport3D> <!-- Camera --> <Viewport3D.Camera> <PerspectiveCamera Position="0,0,100" LookDirection="0,0,-1" UpDirection="0,1,0" /> </Viewport3D.Camera> <!-- Light --> <ModelVisual3D> <ModelVisual3D.Content> <AmbientLight Color="White" /> </ModelVisual3D.Content> </ModelVisual3D> <!-- this doesn't work --> <mediaElementTest:VideoControl /> <!-- but this does? --> <!--<ModelVisual3D> <ModelVisual3D.Content> <GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="-100,-100,0 100,-100,0 100,100,0 -100,100,0" TextureCoordinates="0,1 1,1 1,0 0,0" TriangleIndices="0 1 2 0 2 3" /> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <VisualBrush> <VisualBrush.Visual> <MediaElement Source="http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4" /> </VisualBrush.Visual> </VisualBrush> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> </GeometryModel3D> </ModelVisual3D.Content> </ModelVisual3D>--> </Viewport3D> VideoControl.xaml <UIElement3D x:Class="MediaElementTest.VideoControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"/> VideoControl.xaml.cs public partial class VideoControl { public VideoControl() { InitializeComponent(); Visual3DModel = CreateModel(); } private GeometryModel3D CreateModel() { return new GeometryModel3D { Geometry = new MeshGeometry3D { Positions = new Point3DCollection { new Point3D(-100, -100, 0), new Point3D(100, -100, 0), new Point3D(100, 100, 0), new Point3D(-100, 100, 0) }, TextureCoordinates = new PointCollection { new Point(0, 1), new Point(1, 1), new Point(1, 0), new Point(0, 0) }, TriangleIndices = new Int32Collection { 0, 1, 2, 0, 2, 3 } }, Material = new DiffuseMaterial(new VisualBrush(new MediaElement { Source = new Uri("http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4", UriKind.RelativeOrAbsolute) })) }; } }

  • How to best propagate changes upwards a hierarchical structure for binding?

    - by H.B.
    If i have a folder-like structure that uses the composite design pattern and i bind the root folder to a TreeView. It would be quite useful if i can display certain properties that are being accumulated from the folder's contents. The question is, how do i best inform the folder that changes occurred in a child-element so that the accumulative properties get updated? The context in which i need this is a small RSS-FeedReader i am trying to make. This are the most important objects and aspects of my model: Composite interface: public interface IFeedComposite : INotifyPropertyChanged { string Title { get; set; } int UnreadFeedItemsCount { get; } ObservableCollection<FeedItem> FeedItems { get; } } FeedComposite (aka Folder) public class FeedComposite : BindableObject, IFeedComposite { private string title = ""; public string Title { get { return title; } set { title = value; NotifyPropertyChanged("Title"); } } private ObservableCollection<IFeedComposite> children = new ObservableCollection<IFeedComposite>(); public ObservableCollection<IFeedComposite> Children { get { return children; } set { children.Clear(); foreach (IFeedComposite item in value) { children.Add(item); } NotifyPropertyChanged("Children"); } } public FeedComposite() { } public FeedComposite(string title) { Title = title; } public ObservableCollection<FeedItem> FeedItems { get { ObservableCollection<FeedItem> feedItems = new ObservableCollection<FeedItem>(); foreach (IFeedComposite child in Children) { foreach (FeedItem item in child.FeedItems) { feedItems.Add(item); } } return feedItems; } } public int UnreadFeedItemsCount { get { return (from i in FeedItems where i.IsUnread select i).Count(); } } Feed: public class Feed : BindableObject, IFeedComposite { private string url = ""; public string Url { get { return url; } set { url = value; NotifyPropertyChanged("Url"); } } ... private ObservableCollection<FeedItem> feedItems = new ObservableCollection<FeedItem>(); public ObservableCollection<FeedItem> FeedItems { get { return feedItems; } set { feedItems.Clear(); foreach (FeedItem item in value) { AddFeedItem(item); } NotifyPropertyChanged("Items"); } } public int UnreadFeedItemsCount { get { return (from i in FeedItems where i.IsUnread select i).Count(); } } public Feed() { } public Feed(string url) { Url = url; } Ok, so here's the thing, if i bind a TextBlock.Text to the UnreadFeedItemsCount there won't be simple notifications when an item is marked unread, so one of my approaches has been to handle the PropertyChanged event of every FeedItem and if the IsUnread-Property is changed i have my Feed make a notification that the property UnreadFeedItemsCount has been changed. With this approach i also need to handle all PropertyChanged events of all Feeds and FeedComposites in Children of FeedComposite, from the sound of it, it should be obvious that this is not such a very good idea, you need to be very careful that items never get added or removed to any collection without having attached the PropertyChanged event handler first and things like that. Also: What do i do with the CollectionChanged-Events which necessarily also cause a change in the sum of the unread items count? Sounds like more event handling fun. It is such a mess, it would be great if anyone has an elegant solution to this since i don't want the feed-reader to end up as awful as my first attempt years ago when i didn't even know about DataBinding...

  • ContentPresenter within ControlTemplate cannot change attached dependency property

    - by happyclicker
    Why does the following simplified code not set the font-size of the TextBlock to 50? <Window.Resources> <ControlTemplate TargetType="ContentControl" x:Key="Test"> <ContentPresenter TextBlock.FontSize="50" /> </ControlTemplate> </Window.Resources> <Grid> <ContentControl Template="{StaticResource Test}"> <TextBlock>Test should be rendered big</TextBlock> </ContentControl> </Grid> If I change the value of the FontSize property, visual studio shows me the text in the size I want. After compiling or executing the app, the size of the textblock is always reset to its default size. I have also tested various versions with styles and embedded resources but I end always in the situation that I cannot set attached dp's from within a ControlTemplate that contains a ContentPresenter. Is this by design?

  • '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?

  • XAML get new width and height for Canvas

    - by Jack Navarro
    I have searched through many times but have not seen this before. Probably really simple question but can't wrap my head around it. Wrote a VSTO add-in for Excel that draws a Grid dynamically. Then launches a new window and replaces the contents of the Canvas with the generated Grid. The problem is with printing. When I call the print procedure the canvas.height and canvas.width returned is the old value prior to replacing it with the grid. Sample: string="<Grid Name=\"CanvasGrid\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\">..Lots of stuff..</Grid>"; // Launch new window and replace the Canvas element WpfUserControl newWindow = new WpfUserControl(); newWindow.Show(); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 StringReader stringReader = new StringReader(LssAllcChrt); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas myCanvas = newWindow.FindName("GrphCnvs") as Canvas; myCanvas.Children.Clear(); myCanvas.Children.Add((UIElement)XamlReader.Load(xmlReader)); //To test MessageBox.Show(myCanvas.ActualWidth.ToString()); //return 894 but should be much larger the Grid spans all three of my screens Grid testGrid = myCanvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens //Run code from WpfUserControl.cs after it loads from button click Grid testGrid = canvas.FindName("CanvasGrid") as Grid; MessageBox.Show("Grid " + testGrid.ActualWidth.ToString()); //return 234 but should be much larger the Grid spans all three of my screens So basically I have no way of telling what my new width and height are.

  • Problem showing selected value of combobox when it is bind to a List<T> using Linq to Entities

    I have a combobox which is has itemtemplate applied on it and is bind to a List of entity return using linq. i m using mvvm. It is bind to it successfully but when i set the selected value of it from code at runtime to show the selected value coming from db it doesn't select it. For reference here is my combobox xaml.

  • How can my controls size be NaN when it is actually shown?

    - by Stian Karlsen
    I have a Grid which contains an Image in one of its columns. The image itself does not have any Width or Height set, but its size is correctly controlled through the ColumnDefinition set. From this I would assume that the image controller actually has a Width and Height set, but when I try to bind another element to its Width and Height it doesn't work. When debugging it turns out that the value of Image.Height and Image.Width are NaN. Why? <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="350"></ColumnDefinition> <ColumnDefinition Width="*"></ColumnDefinition> <ColumnDefinition Width="10"></ColumnDefinition> <ColumnDefinition Width="*"></ColumnDefinition> </Grid.ColumnDefinitions> <Grid Grid.Column="0" Margin="5"> <Image x:Name="_image" Source="image.jpg"></Image> </Grid> </Grid>

  • drag-drop and data binding in MVVM

    - by Benny
    My ViewModel: class ViewModel { public string FileName {get;set;} } and in my View I bind a label's content to ViewModel's FileName. now When I do drag-drop a file to my View, How can I update the label's Content property, so that the ViewMode's FileName also get updated via binding? Directly set the label's Content property won't work, it just simply clear the binding.

  • What should go in each MVVM triad?

    - by Harry
    OK, let's say I am creating a program that will list users contacts in a ListBox on the left side of the screen. When a user clicks on the contact, a bunch of messages or whatever appears in the main part of the window. Now my question is: how should the MVVM triads look? I have two models: Contact, and Message. The Contact model contains a list of Message models. Each ViewModel object will contain a single corresponding Model, right? And what about the Views? I have a "MainView" that is the main window, that will have things like the menu, toolbar etc. Do I put the ListBox in the MainView? My confusion is with what to put where; for example, what should the ContactView contain? Just a single instance of a contact? So the DataTemplate, ControlTemplate, context menus, styles etc for that single contact, and then just have a ListBox of them in the MainView...? Thanks.

  • Row Prefix - ItemsControl with UniformGrid

    - by tenfour
    I am using an ItemsControl to display a List<byte> in hex. The ItemsPanelTemplate is a UniformGrid with a fixed number of columns: <ItemsControl HorizontalAlignment="Left" VerticalAlignment="Top" ItemsSource="{Binding}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <UniformGrid Columns="16"/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding StringFormat='\{0:X2\}'}" Margin="5,5,5,0"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> I'd like to prefix each row with an 'Address' column, just like you'd see with the Notepad++ 'HEX-Editor' plugin. That is, since I have 16 columns, each row should be prefixed something like this: 0000 [00 01 02 .... 0F] 0010 [10 11 12 .... 1F] 0020 [20 21 22 .... 2F] ... Any suggestions?

  • With MVVM, does each UI window have its own ViewModel?

    - by j0rd4n
    When I'm designing multiple views under the MVVM pattern, does each view get its own ViewModel or do they all share the same one? I understand that this is ultimately a flexible decision, but what is the best practice? My gut tells me to have a ViewModel for each view (i.e. each separate UI window). All of the blog examples of MVVM show a single view but not much beyond that.

  • User Control - dependency property to Change Image Issues

    - by mflair2000
    i'm having issues setting the Image from a dependency property. It seems like the trigger doesnt fire. I just want hide/show and image, or set the source if possible. public static readonly DependencyProperty HasSingleValueProperty = DependencyProperty.Register("HasSingleValue", typeof(bool), typeof(LevelControl), new FrameworkPropertyMetadata(false,FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public bool HasSingleValue { get { return (bool)GetValue(HasSingleValueProperty); } set { SetValue(HasSingleValueProperty, value); } } public LevelControl() { this.InitializeComponent(); //this.DataContext = this; LayoutRoot.DataContext = this; } //Control Markup <Grid x:Name="LayoutRoot"> <Image x:Name="xGreenBarClientTX" HorizontalAlignment="Stretch" Height="13" Margin="7,8.5,7,0" Stretch="Fill" VerticalAlignment="Top" Width="47" Canvas.Left="181.67" d:LayoutOverrides="Height" > <Image.Style> <Style TargetType="{x:Type Image}"> <Style.Triggers> <DataTrigger Binding="{Binding HasSingleValue}" Value="True"> <Setter Property="Opacity" Value="100"/> </DataTrigger> <DataTrigger Binding="{Binding HasSingleValue}" Value="False"> <Setter Property="Opacity" Value="0"/> </DataTrigger> </Style.Triggers> </Style> </Image.Style> </Image>

  • Programmatically Binding to a Property

    - by M312V
    I know it's a generic title, but my question is specific. I think it will boil down to a question of practice. So, I have the following code: public class Component : UIElement { public Component() { this.InputBindings.Add(new MouseBinding(SomeCommandProperty, new MouseGesture(MouseAction.LeftClick))); } } I could easily aggregate the ViewModel that owns SomeCommandProperty into the Component class, but I'm currently waiving that option assuming there is another way. Component is a child of ComponentCollection which is child of a Grid which DataContext is the ViewModel. ComponentCollection as the name suggests contains a collection of Components. <Grid Name="myGrid"> <someNamespace:ComponentCollection x:Name="componentCollection"/> </Grid> It's the same scenario as the XAML below, but with TextBlock. I guess I'm trying to replicate what's being done in the XAML below programatically. Again, Component's top most ancestor's DataContext is set to ViewModel. <Grid Name="myGrid"> <TextBlock Text="SomeText"> <TextBlock.InputBindings> <MouseBinding Command="{Binding SomeCommandProperty}" MouseAction="LeftClick" /> </TextBlock.InputBindings> </TextBlock> </Grid> Update 1 Sorry, I'm unable to comment because I lack the reputation points. Basically, I have a custom control which inherit from a Panel which children are a collection of Component. It's not a hack, like I've mentioned, I could directly have access to SomeCommandProperty If I aggregate the ViewModel into Component. Doing so, however, feels icky. That is, having direct access to ViewModel from a Model. I guess the question I'm asking is. Given the situation that Component's parent UIElement's DataContext is set to ViewModel, is it possible to access SomeCommandProperty without Component owning a reference to the ViewModel that owns SomeCommandProperty? Programatically, that is. Using ItemsControl doesn't change the fact that I still need to bind SomeCommandProperty to each Items.

  • Force redraw before long running operations

    - by Joshua
    When you have a button, and do something like: Private Function Button_OnClick Button.Enabled = False [LONG OPERATION] End Function Then the button will not be grayed, because the long operation prevents the UI thread from repainting the control. I know the right design is to start a background thread / dispatcher, but sometimes that's too much hassle for a simple operation. So how do I force the button to redraw in disabled state? I tried .UpdateLayout() on the Button, but it didn't have any effects. I also tried System.Windows.Forms.DoEvents() which normally works when using WinForms, but it also had no effect.

  • Can we manipulate (subtract) the value of a property while template bidning?

    - by Subhen
    Hi, I am currently defining few grids as following: <Grid.RowDefinitions> <RowDefinition Height="{TemplateBinding Height-Height/5}"/> <RowDefinition Height="{TemplateBinding Height/15}"/> <RowDefinition Height="{TemplateBinding Height/20}"/> <RowDefinition Height="{TemplateBinding Height/6}"/> </Grid.RowDefinitions> While the division works fine , the subtraction isn't yielding the output. Ialso tried like following: <RowDefinition Height="{TemplateBinding Height-(Height/5)}"/> Still no result. Any suggestions plz. Thanks, Subhen ** Update ** Now In My XAML I tried implementing the IvalueConverter like : <RowDefinition Height="{TemplateBinding Height, Converter={StaticResource heightConverter}}"/> Added the reference as <local:medieElementHeight x:Key="heightConverter"/> In side generic.cs I have coded as following: public class medieElementHeight : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { //customVideoControl objVdeoCntrl=new customVideoControl(); double custoMediaElementHeight = (double)value;//objVdeoCntrl.customMediaPlayer.Height; double mediaElementHeight = custoMediaElementHeight - (custoMediaElementHeight / 5); return mediaElementHeight; } #region IValueConverter Members object IValueConverter.ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } #endregion } But getting the exception Unknown Element Height in the element RowDefination.

  • How to implement a TypeConverter for a type and property I don't own?

    - by CannibalSmith
    This is annoying: <GeometryDrawing> <GeometryDrawing.Pen> <Pen Brush="Black"/> </GeometryDrawing.Pen> </GeometryDrawing> I want this: <GeometryDrawing Pen="Black"/> So I write a TypeConverter: public class PenConverter : TypeConverter { static readonly BrushConverter brushConverter = new BrushConverter(); public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType) { if (sourceType == typeof(string)) return true; return base.CanConvertFrom(context, sourceType); } public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value) { var s = value as string; if (a != null) { var brush = brushConverter.ConvertFromInvariantString(s) as Brush; return new Pen(brush, 1); } return base.ConvertFrom(context, culture, value); } } Now, how do I link it up with the Pen type? I can't just add a TypeConverterAttribute to it as I don't own it (nor do I own GeometryDrawing.Pen property).

  • C# Dataset Dynamically Add DataColumn

    - by Wesley
    I am trying to add a extra column to a dataset after a query has completed. I have a database relationship of the following: Employees / \ Groups EmployeeGroups Empoyees holds all the data for that individual, I'll name the unique key the UserID. Groups holds all the groups that a employee can be a part of, i.e. Super User, Admin, User; etc. I will name the unique key GroupID EmployeeGroups holds all the associations of which groups each employee belongs too. (UserID | GroupID) What I am trying to accomplish is after querying for a all users I want to loop though each user and add what groups that user is a part of by adding a new column to the dataset named 'Groups' which is a string to insert the values of the next query to get all the groups that user is a part of. Then by user of databinding populate a listview with all employees and their group associations My code is as follows; Position 5 is the new column I am trying to add to the dataset. string theQuery = "select UserID, FirstName, LastName, EmployeeID, Active from Employees"; DataSet theEmployeeSet = itsDatabase.runQuery(theQuery); DataColumn theCol = new DataColumn("Groups", typeof(string)); theEmployeeSet.Tables[0].Columns.Add(theCol); foreach (DataRow theRow in theEmployeeSet.Tables[0].Rows) { theRow.ItemArray[5] = "1234"; } At the moment, the code will create the new column but when i assign the data to that column nothing will be assigned, what am I missing? If there is any further explination or information I can provide, please let me know. Thank you all
