• EventTrigger RoutedEvent in wpf xaml

  - by Cinaird

  I have a problem in wpf xaml and i'm pretty new on this so it may be something basic i want to rotate a ellipse 360 degree <Ellipse Name="test" Fill="Black" StrokeThickness="5" Margin="0,0,0,0" Height="66"> <Ellipse.Triggers> <EventTrigger RoutedEvent="Ellipse.Loaded" SourceName="test"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="test" Storyboard.TargetProperty="(Ellipse.RenderTransform).(RotateTransform.Angle)" From="0" To="360" Duration="0:0:0.5" RepeatBehavior="1x" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Ellipse.Triggers> </Ellipse> But nothing happens, what is wrong?

• WPF 3D - Need help writing conversion methods between 2D and 3D (Point3DToPoint and PointAndZToPoint

  - by DanM

  I'm new to WPF 3D, so I may just be missing something obvious, but how do I convert from 3D to 2D and (for a given z location) from 2D to 3D? Specifically, I need two conversion methods: Point3DToPoint - If I have an (x, y, z) coordinate in the 3D world, how do I determine the (x, y) coordinate on the projected 2D surface. Method signature: public Point Point3DToPoint(Point3D point3D) PointAndZToPoint3D - If I have an (x, y) coordinate on the projected 2D surface and a z location in the 3D world, how do I determine the intersecting (x, y, z) coordinate in the 3D world? Method signature: public Point3D PointAndZToPoint3D(Point point, double z) I'd like the 2D coordinate to be the location measured from the upper-left corner of Viewport3D and the 3D coordinate to be the location relative to the origin (0, 0, 0) of the 3D world. Note 1: I found this related question, but it only addresses conversion from 3D to 2D (not the reverse), and I'm not sure if the answers are up-to-date. Note 2: I'm currently using .NET 3.5, but if there are improvements in .NET 4.0 that would help me, please let me know.

• How to Animate a Gradient on a Path to visualize data flow in WPF/WCF app

  - by John

  I have an interesting project where several "nodes" on a cnavas are connected via a Path similiar to a mindmap tree. The path is used to visualize the connection state between two nodes. Red means the nodes are disconnected, green means they're connected. The next step would be to illustrate data flow (from A to B or B to A) using that path and an animation. Basically I would want to start the animation with the data transfer and stop it when the transfer is complete. Does anyone know how this could be done in WPF?

• wpf toolkit (Feb 2010) datagrid with MVVM - style reveals name of view model on 'spare column'

  - by Andy Clarke

  Hi, I've just updated my app with the latest WPF toolkit and I've now got an issue with my styling. When I bind some data with, for example, two columns to the grid, the spare area at the right shows the name of the ViewModel in the header. I can understand why, because the data grids data context is the ViewModel and I'm defining my header style as follows ... <WpfToolkit:DataGridHeaderBorder <Border BorderBrush="Blue" BorderThickness="0,1,0,0"> <TextBlock Text="{Binding}" Margin="4,0,4,0" /> </Border> </WpfToolkit:DataGridHeaderBorder> Do I now need a separate style for the 'spare column' or something? Can anyone assist please? Cheers, Andy

• WPF Hide DataGridColumn via a binding

  - by Greg R

  For some reason I can't hide WPF Toolkit's DataGridColumn. I am trying to do the following: <dg:DataGridTemplateColumn Header="Item Description" Visibility="{Binding IsReadOnly}"> <dg:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBox Text="{Binding Path=ItemDescription}" /> </DataTemplate> </dg:DataGridTemplateColumn.CellTemplate> This doesn't work, since it's looking for a IsReadOnly property on the ItemSource (not a property of the current class). If add this as a property of the ItemSource class that implements INoifyPropertyChanged, it still doesn't hide the column. Is there a way around this? I want the column to hid when a button click changes IsReadOnly property. Assume IsReadOnly returns a Visibility value and is a dependency property I am completely stuck, I would really appreciate the help! Thanks a lot!

• WPF MenuItem ViewModel Command

  - by Jon Archway

  Hi, I am fairly new to WPF and am struggling a little with a scenario. I have a menu which has menu items. When one of these menu items gets clicked a method needs to be called that will do something based upon the text displayed associated with that menu item. So for example, the menu item's content was "test" so I would need to do something with "test". FYI, this "something" directly affects a collection on the ViewModel. This is easy to achieve using the click event and no ViewModel, but I was trying to implement MVVM using an explicit ViewModel. So I started to look into Commands but cannot see how I would pass anything from the View back into the Command in the ViewModel. Any suggestions on what I should be doing here? Thanks

• WPF - Have a list source defined at runtime but still have sample data for design time

  - by Vaccano

  I have some ListBoxes in my WPF app. I would like to be able to view how the design looks with out having to run the app. But I still want to be able to bind to ItemsSource to my View Model. I know I saw a blog post on how to do this, but I cannot seem to find it now. To reiterate, I want dummy data at design time, but real data at run time and not break the MVVM pattern. Any ideas?

• Navigate between screens in WPF

  - by Greg R

  This should be a very basic design question, but for some reason it doesn't seem to be well documented (maybe due to its simplicity?). If I'm building a dashboard application in WPF that brig up different CRM tasks and I want to navigate between screens, is this the best way to do this, or is there a better way? So for example I have Log In Screen - Main Menu Screen - Screen to one of different utilities var orderManagerWindow = new MyXamlView(); var loginWindow = Application.Current.MainWindow; orderManagerWindow.Left = loginWindow.Left; orderManagerWindow.Top = loginWindow.Top; Application.Current.MainWindow = orderManagerWindow; orderManagerWindow.Show(); loginWindow.Close(); I would really appreciate help and suggestions!

• WPF Binding issues

  - by Nitin Chaudhari

  I have WPF window which binds a local Dependency property to a property of my usercontrol. So now I see the value which the window gave me in my usercontrol. I achieve this by setting DataContext of window to the window itself Now once the window is loaded i set the DataContext of usercontrol to a ViewModel class, and at some point of time(based on user action) the control changes values in the control. All fine so far. But now the changed value is not reflected in Windows dependency property. How I can resolve this issue?

• Setting the background color of WPF TabControl inactive tabs

  - by David Veeneman

  Is there a simple way to set the background brush of all inactive tabs in a WPF TabControl? I want to emulate the look of VS 2010 on a TabControl--the background color of the control's inactive tabs should match the background color of the window in which the TabControl is sited, so that you see only the text of the tab, and not the tab itself. I know it will take a ControlTemplate to do it; I am trying to figure out what to put in the control template. Put another way, How do I specify that a particular brush should be applied to all inactive tabs? Thanks for your help.

• Binding a slider value on the height of its thumb in WPF

  - by sofri

  Hi, I have a databinding problem in WPF. I would like to "customise" a slider in a way that the thumb grows when you move the slider to the right and the thumb shrinks when you move the slider to the left. So I edited the template for the slider and changed the look of the slider so the slider looks like I want it to. But now I have to bind the height of the thumb to the value of the slider but I do not know how that works. I did some simple data binding things but I cannot figure out how I can bind this "thumb height" that's inside of my slider's template to the slider's value that's inside the User Control where my slider is in. So how can I do it?

• WPF - Make two controls the same size

  - by John Michaels

  Is there any way to make two controls that are in different containers the same size in WPF? For example, suppose you have two textboxes: textbox1 and textbox2. Textbox1 is in a grid and its size can grow and shrink when the user resizes the window. Textbox2 is in another part of the window and I need it to always have the same size as textbox1. Is there any way to do this? Keep in mind SharedSizeGroup will not work because the textboxes are in different containers. Also, I've tried binding textbox2's height property to textbox1 and that doesn't seem to work either. Finally, I tried catching textbox1's SizeChanged event, but its Height property is always NaN for some reason.

• WPF, animate over container boundaries

  - by ImIan

  Hi, I'm learning WPF and have a specific goal. Imagine you have a grid (3 rows by 3 columns), and a control, say a simple blue rectangle fills the middle cell. When I click on the cell I want the square to rotate smoothly through 180 degrees. The specific issue I have at the moment is; as the rectangle rotates, it won't change its dimensions, so it will extend beyond the boundary of the cell. I don't want it to clip, i want it to appear on top, partially obscuring surrounding cells. The second part of this is, if there is one cell that fills the entire window, and I click on the blue rectangle in that cell, can I make the rectangle rotate and extend beyond the sides of the form? If that doesn't make sense, please ask. I'm finding it hard to google because I don't know the exact terms I should be using. Thank you

• Splitting up/merging windows in WPF

  - by drasto

  I'm new to WPF but I need to implement following functionality: I have a window that contains one Grid (might be changed to stack panel or something else). In that Grid I have 2 columns, each of them contains another Grid. Lets call them gridFirst and gridSecond. There is also GridSplitter in first column allowing to resize the columns. I want to provide a button that will allow to separate gridFirst from this window and display it "as it is" in another window. How do I do that? It would be nice if the new window had a same menu as the original window without me having to copy-paste (that not a good coding practise) all its code to the new window. Thanks for answers

• WPF TreeView binding to a simple object

  - by esse

  I have a simple object as such: public class Info { public string Name {get; set;} public int Count {get; set;} public DateTime TimeStamp {get; set;} } I want to bind a collection of these objects to a WPF TreeView and have the properties on the Info objects show up as sub TreeViewItems, like so: Item 1 Name: Bill Count: 3 TimeStamp: 12/05/2010 09:06:00 AM Item 2 Name: Chris Count: 22 TimeStamp: 11/05/2010 11:34:00 AM Item 3 Name: Toby Count: 1 TimeStamp: 09/05/2010 05:55:00 PM How can I achieve this through XAML?

• Wrapping WPF UserControl inside VisualStudio Item Template

  - by karthik84

  I am currently started working on a project which will allow users to design reports inside visual studio. Previously, for my similar Winforms App, I had extended the IComponent (Component Class) and wrote our VS Like designer kind of custom control which will allow users to drag drop controls from the visual studio toolbox and then I export it as a VisualStudio C#&VB ItemTemplate. Now I am trying to recreate the same control using WPF considering its power, extensiblity. Could anyone shed some lights on this, on what would be the most preferable way of doing this ? Thanks in advance.

• Using themes in visio

  - by JohnW

  I'm looking for a good reference on how to properly use themes in Visio. Here's been my experience so far: Create a flowchart diagram - nothing fancy, just all black & white. No formatting applied to any object. Select & apply a theme to the diagram. Despite the theme showing a set of matching colors, the diagram now has a single color applied to all objects. Right-click the object, format, fill, and pick a color from the set of matching theme colors. End up with an amalgamation of the original theme color I picked (blue) and the new color (green). With enough 'playing' with the object, I can get it to look OK, but it feels like I'm missing something, that it shouldn't be this hard to get a matching color. Any advice would be appreciated. :)

• Dark Windows Themes

  - by CaffGeek

  I spend all day staring at computer screens. I have changed my Visual Studio theme to a dark theme, and find it much easier on the eyes. I'd like to change the rest of windows. Unfortunately, the only themes installed by default that are dark, are high contrast. Which is NOT what I am going for here. I can't seem to find an official dark theme, that isn't high contrast. I've found dynamic black, which is a good example of what I'm looking for, but it's not an official theme. Is there anything out there?

• Binding Image.Source to String in WPF ?

  - by Mohammad

  I have below XAML code : <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" DataContext="{Binding RelativeSource={RelativeSource Self}}" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <Grid> <Image x:Name="TestImage" Source="{Binding Path=ImageSource}" /> </Grid> </Window> Also, there is a method that makes an Image from a Base64 string : Image Base64StringToImage(string base64ImageString) { try { byte[] b; b = Convert.FromBase64String(base64ImageString); MemoryStream ms = new System.IO.MemoryStream(b); System.Drawing.Image img = System.Drawing.Image.FromStream(ms); ////////////////////////////////////////////// //convert System.Drawing.Image to WPF image System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(img); IntPtr hBitmap = bmp.GetHbitmap(); System.Windows.Media.ImageSource imageSource = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions()); Image wpfImage = new Image(); wpfImage.Source = imageSource; wpfImage.Width = wpfImage.Height = 16; ////////////////////////////////////////////// return wpfImage; } catch { Image img1 = new Image(); img1.Source = new BitmapImage(new Uri(@"/passwordManager;component/images/TreeView/empty-bookmark.png", UriKind.Relative)); img1.Width = img1.Height = 16; return img1; } } Now, I'm gonna bind TestImage to the output of Base64StringToImage method.

• Automatic linebreak in WPF label

  - by Vlad

  Dear all, is it possible for a WPF Label to split itself automatically into several lines? In my following example, the text is cropped at the right. <Window x:Class="..." xmlns="..." xmlns:x="..." Height="300" Width="300"> <Grid> <Label> `_Twas brillig, and the slithy toves did gyre and gimble in the wabe: all mimsy were the borogoves, and the mome raths outgrabe.</Label> </Grid> </Window> Am I doing something wrong? Taking other controls is unfortunately not a good option, since I need support of access keys. Replacing the Label with a TextBlock (having TextWrapping="Wrap"), and adjusting its control template to recognize access keys would be perhaps a solution, but isn't it an overkill? Edit: having a non-standard style for label will break skinning, so I would like to avoid it if possible.

• WPF Datagrid set the column values only when the row is left

  - by Noam

  Hello I have a simple class. When I use it in winforms binding, whenever I change a value of a cell and leave the cell, the property immediately get changed. Using WPF Datagrid, whenever i change a value of a cell, the property gets set only after I leave the row. That is problematic for me. What am I doing wrong? Here is my code: public class MyClass : IEditableObject, INotifyPropertyChanged { string _name, _lastName; public string Name { get { return _name; } set { _name = value; _lastName = value + " xxx"; OnPropertyChanged("LastName"); MessageBox.Show("Test"); } } private void OnPropertyChanged(string p) { var x = new PropertyChangedEventArgs(p); if (PropertyChanged != null) PropertyChanged(this, x); } public string LastName { get { return _lastName; } set { _lastName = value; } } public void BeginEdit() { } public void CancelEdit() { } public void EndEdit() { } public event PropertyChangedEventHandler PropertyChanged; } public class myBindingList : BindingList<MyClass> { public myBindingList() { AllowNew = true; Add(new MyClass { Name = "noam" }); Add(new MyClass { Name = "yael" }); } }

• WPF: Change the style of a ViewBox depending upon the amount of data

  - by Brett Rigby

  Hi there, I have a WPF app that has a ViewBox to display the items in my collection, diplaying a 2-column grid for my results. What I'd like to do is, depending on the number of items in my collection, change the number of columns. E.g if there are < 10 items in the list, then show them in just 1 column; If there are 10 items in my list, then show them in 2 columns; If there are 20 items in my list, then show 3 columns. Here's what I have at present: <Viewbox> <ItemsControl ItemsSource="{Binding myCollection}" Style="{DynamicResource myStyle}" /> </Viewbox> Here's what myStyle currently defines: <Style x:Key="myStyle" TargetType="{x:Type ItemsControl}"> <Setter Property=ItemsControl.ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <UniformGrid Columns="2" /> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> How can I make this code work to the above requirement? Thanks.
