  • Trapping events within list box item templates in WPF

    - by AC
    I've got listbox that employs an item template. Within each item in the list, as defined in the template there is a button. When the user clicks the button I change a value in the data source that defines the sort order of the list. Changing the datasource is not a problem as this is working just fine within my application template. However my next step is to reload the listbox with the new sorted data source. I've tried doing this from the tempalte but it apparently doesn't have access (or I can't figure out how to get access) to the parent elements so I can reset the .ItemSource property with a newly sorted data source. Seems like this is possible but the solution is eluding me :(

  • WPF closing child- closes parent-window

    - by Thomas Spranger
    i have the pretty same sample as mentioned here. Fast concluded: MainWindow closes when the last childwindow is closed. My Problem: I couldn't solve my problems with the described solutions. I can't produce a program where it als takes place. Only in one of my bigger progs. Maybe someone has an idea or knows any further steps. Thanks for reading - Thomas As requested here's a bit of code: This is the part in the MainWindow: bool editAfterSearch = false; Movie selectedMovie = (Movie)this.listView.SelectedItem; Movie backup = (Movie)selectedMovie.Clone(); if (new OnlineSearchWindow().EditMovieViaOnlineSearch(ref selectedMovie, out editAfterSearch)) { this.coverFlow.Update(selectedMovie); } And that's the part of the ChildWindow: public bool EditMovieViaOnlineSearch(ref Movie preset, out bool editAfter) { this.exitWithOk = false; this.editMovieAfterSearch = false; this.tbx_SearchTerm.Text = preset.Title; this.linkedMovie = preset; this.ShowDialog(); editAfter = editMovieAfterSearch; if (this.exitWithOk) { this.linkedMovie.CloneOnlineInformation(ref preset); preset.Bitmap = this.linkedMovie.Bitmap; return true; } else { return false; } }

  • WPF ContextMenu bind some property to another property of the same control

    - by bebicasoft
    I have a ContextMenu and a ColumnHeaderStyle defined in Window.Resource section witch i use-it to a DataGrid ColumnHeader. My code is something like this: <ContextMenu x:Key="cm_columnHeaderMenu"/> <Style x:Key="DefaultColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}"> <Setter Property="ContextMenu" Value="{StaticResource cm_columnHeaderMenu}" /> </Style> <DataGrid Grid.Column="2" Grid.Row="1" x:Name="dgridFiles" IsReadOnly="True" ColumnHeaderStyle="{StaticResource DefaultColumnHeaderStyle}"> I want to know if I can (and if the answer it true, then HOW I could do it) bind the ContextMenu Visibility property to same control ContextMenu Items.Count>0 property. Initially based on some other treeView control selections made there shoud be no items in the context menu, but i wish to add dinamically items in ContextMenu based on selection in treeView. This part is done, the context has those items. On some selections there are no-items, but still on the grid it appears an empty ContextMenu. So I believe the easiest part it would be to bind the Visibility to Items.Count property of the same control. Sorry if my english is not good enought, I'll try to explain better if i didnt make clear 1st time.

  • wpf: capturing mouse does not work

    - by amethyste
    hello I am developing an kind of outlook calendar application where I need to make the appointment resizable from mouse. My first try with a thumb did not work properly so I tried another way. What I did is that: 1) on the botton of the appointmennt panel I added a rectangle to figure out the resize zone (the thumb). The appointment panel is put on a grid panel. 2) I intercept down event on the rectangle and send event to this code: private Point startPoint; private void OnResizeElementMouseDown(object sender, MouseButtonEventArgs e) { e.Handled = true; this.MouseMove += new MouseEventHandler(ResizeEndElement_MouseMove); this.MouseLeftButtonUp += new MouseButtonEventHandler(OnResizeElementMouseUp); // some code to perform new height computation Mouse.Capture(this); } where this is the appointment panel that own the thumb. Decreasing height works well. But increasing is more difficult. If I move the mouse very very slowly it's OK, if I speed it up a little bit it tends to leave out the appointment panel and then all MouseMove event are lost. I thought Mouse.Capture() was propose to solve this kind of problem, but in fact not. Does anybody know what is wrong in my code?

  • Issue with child of custom Decorator class in WPF (c#)

    - by galacticgrug
    I need a custom border that renders a little differently than a normal border. I made a class that inherited from Decorator as follows class BetterBorder : Decorator { protected override Size ArrangeOverride(Size arrangeSize) { return arrangeSize; } protected override void OnRender(DrawingContext dc) { //these values are calculated elsewhere dc.DrawGeometry(backgroundBrush, borderPen, pathGeometry); } } //Properties and helper methods below this All of this works fine until I try to add a child to the control, the control can be added but is not visible and seems to be moved off BetterBorders visible client area. If I inherit from Border everything works fine, what am I missing?

  • WPF custom DependencyProperty notify changes

    - by morsanu
    Hey guys I have a class called MyComponent and it has a DependencyProperty caled BackgroundProperty. public class MyComponent { public MyBackground Background { get { return (MyBackground)GetValue(BackgroundProperty); } set { SetValue(BackgroundProperty, value); } } public static readonly DependencyProperty BackgroundProperty = DependencyProperty.Register("Background", typeof(MyBackground), typeof(MyComponent), new FrameworkPropertyMetadata(default(MyBackground), new PropertyChangedCallback(OnPropertyChanged))); } MyBackground is a class that derives from DependencyObject and it has some DependencyProperties. public class MyBackground : DependencyObject { public Color BaseColor { set { SetValue(BaseColorProperty, value); } get { return (Color)GetValue(BaseColorProperty); } } public static readonly DependencyProperty BaseColorProperty = DependencyProperty.Register("BaseColor", typeof(Color), typeof(MyBackground ), new UIPropertyMetadata(Colors.White)); [...] } Now, what I want is when a property from MyBackground is changed, MyComponent to be notified that MyBackground has changed and the PropertyChangedCallback named OnPropertyChanged to be called.

  • Group panel of WPF ListBox

    - by rulestein
    I have a listbox that is grouping the items with a GroupStyle. I would like add a control at the bottom of the stackpanel that holds all of the groups. This additional control needs to be part of the scrolling content so that the user would scroll to the bottom of the list to see the control. If I were using a listbox without the groups, this task would be easy by modifying the ListBox template. However, with the items grouped, the ListBox template seems to only apply on a per group basis. I can modify the GroupStyle.Panel, but that doesn't allow me to add items to that panel. <ListBox> <ListBox.ItemsPanel> <ItemsPanelTemplate> <WrapPanel/> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.GroupStyle> <GroupStyle> <GroupStyle.Panel> <ItemsPanelTemplate> <VirtualizingStackPanel/> **<----- I would like to add a control to this stackpanel** </ItemsPanelTemplate> </GroupStyle.Panel> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Grid> <ItemsPresenter /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </ListBox.GroupStyle> This should give an idea of what I need to do:

  • WPF buttons same/recommended width

    - by rwallace
    Suppose you have a window with multiple buttons such as Ok/Cancel or Yes/No/Cancel. All the buttons need to be the same width. Obviously this could be done by just guessing a number and hardwiring all of them to that number. Is there a better way to do it, one that would take into account preferred/recommended sizes (just how wide should an Ok button be anyway? This is not a rhetorical question, I actually don't know the answer!), what's needed by the text of the longest caption, what happens if the font size is increased etc?

  • Printdialog in multithreaded wpf window thrown TargetInvocationException

    - by Nils
    I have designed a multithreaded app, which is starting most windows in an dedicated thread like this: Thread newWindowThread = new Thread(new ThreadStart(ThreadStartingPoint)); newWindowThread.SetApartmentState(ApartmentState.STA); newWindowThread.IsBackground = true; newWindowThread.Start(); However, if in one of those window-in-own-thread I try to print something by simply calling PrintDialog pDialog = new PrintDialog(); bool? doPrint = pDialog.ShowDialog(); I get a TargetInvocationException - it does look like the PrintDialog does not reside in the same thread as my window. Is there any way to create a thread-agnostic (or "thread-save") PrinterDialog ?

  • create board for game with events support in WPF

    - by netmajor
    How can I create board for simple game, looks like for chess,but user could dynamically change number of column and rows? In cells I could insert symbol of pawn, like small image or just ellipse or rectangle with fill. This board should have possibility add and remove pawn from cells and move pown from one cell to another. My first idea was Grid. I do it in code behind, but it's hurt to implement events or everything in runtime create board :/ int size = 12; Grid board = new Grid(); board.ShowGridLines = true; for (int i = 0; i < size;i++ ) { board.ColumnDefinitions.Add(new ColumnDefinition()); board.RowDefinitions.Add(new RowDefinition()); } //komputer Rectangle ai = new Rectangle(); ai.Height = 20; ai.Width = 20; ai.AllowDrop = true; ai.Fill = Brushes.Orange; Grid.SetRow(ai, 0); Grid.SetColumn(ai,0); //czlowiek Rectangle hum = new Rectangle(); hum.Height = 20; hum.Width = 20; hum.AllowDrop = true; hum.Fill = Brushes.Green; Grid.SetRow(hum,size); Grid.SetColumn(hum,size); board.Children.Add(ai); board.Children.Add(hum); this.Content = board; It's a way to do this dynamically col and row change in XAML ? It's better way to implement that board create and implement events on move pawn from one cell to another ?

  • How to obtain the panel within a treeview (WPF)

    - by sperling
    How can one obtain the panel that is used within a TreeView? I've read that by default TreeView uses a VirtualizingStackPanel for this. When I look at a TreeView template, all I see is <ItemsPresenter />, which seems to hide the details of what panel is used. Possible solutions: 1) On the treeview instance ("tv"), from code, do this: tv.ItemsPanel. The problem is, this does not return a panel, but an ItemsPanelTemplate ("gets or sets the template that defines the panel that controls the layout of the items"). 2) Make a TreeView template that explicitly replaces <ItemsPresenter /> with your own ItemsControl.ItemsPanel. I am providing a special template anyways, so this is fine in my scenario. Then give a part name to the panel that you place within that template, and from code you can obtain that part (i.e. the panel). The problem with this? see below. (I am using a control named VirtualTreeView which is derived from TreeView, as is seen below): , use following: -- [sorry folks about poor formatting here, this is my first post, I tried 4 spaces for code... doesn't seem to work?] [I stripped out all clutter here for visibility...] The problem with this is: this immediately overrides any TreeView layout mechanism. Actually, you just get a blank screen, even when you have TreeViewItems filling the tree. Well, the reason I want to get a hold of the panel is to take some part in the MeaureOverride, but without going into all of that, I certainly do not want to rewrite the book of how to layout a treeview. I.e., doing this the step #2 way seems to invalidate the point of even using a TreeView in the first place. Sorry if there is some confusion here, thanks for any help you can offer.

  • WPF Animate a Maxtrix using interpolation

    - by Mark
    Im having a issue with my application that is using touch gestures to scale, translate and rotate my scene. I was using a TransformGroup which contained TranslateTransform, ScaleTransform and a RotateTransform but I could not get the movement correct, it always jumps and skips, so I moved to a MaxtrixTransform which I was able to use much easier to get my scene to be zoomable, rotatable and panable nicely. However, what I later found out was that you cannot animate smoothly (using interpolation) the values of a Matrix, for what reason I have no idea, but its part of the MSDN doco and the properties of the Matrix are not dependency properties anyways... Has anyone had any luck animating a maxtrix to make it smooth? The only idea(s) I have had is to animate a few different, custom DP which all have callbacks that I update the Matrix from OR To convert the Maxtix to a set of Transform object that I then animate and then afterwords convert back. Is there a smarter way to do this?

  • WPF DataGridRow Template - how to achieve Selected event

    - by user1809972
    I would like to override the DataGridRow template depending on the datatype of object bound to the grid. If the type is label, it just shows a Label. Otehrwise, it shows the cells. Follwing is the xaml. <DataTrigger Binding="{Binding Path=IsLabel, UpdateSourceTrigger=PropertyChanged}" Value="True"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridRow}"> <Grid> <Label HorizontalAlignment="Center" Padding="3,3,3,3" FontWeight="Bold" Content="{Binding Id}"/> </Grid> </ControlTemplate> </Setter.Value> </Setter> </DataTrigger> The grid looks ok. But, when the Label is clicked, it doesnt raise the Selection changed event for the DataGridRow. How do I achieve this behaviour? This label should just behave as any other DataGridRow(with the default template). Thanks

  • WPF data-bound ComboBox only shows first item of ItemsSource list

    - by Mark
    Hi all, I'm sure I'm doing something stupid but for the life of me I can't think of right now. I have a ComboBox that is data-bound to a list of Layout objects. The list is initially empty but things are added over time. When the list is updated by the model the first time, this update reflects properly in the ComboBox. However, subsequent updates never show up in the ComboBox even though I can see that the list itself contains these items. Since the first update works, I know the data-binding is OK - so what am I doing wrong here? Here's the XAML (abridged): <Grid HorizontalAlignment="Stretch"> <ComboBox ItemsSource="{Binding Path=SavedLayouts, diagnostics:PresentationTraceSources.TraceLevel=High}" DisplayMemberPath="Name" SelectedValuePath="Name" SelectedItem="{Binding LoadLayout}" Height="25" Grid.Row="1" Grid.Column="0"></ComboBox> </Grid> And the related part of the model: public IList<Layout> SavedLayouts { get { return _layouts; } } public Layout SaveLayout( String data_ ) { Layout theLayout = new Layout( SaveLayoutName ); _layouts.Add( theLayout ); try { return theLayout; } finally { PropertyChangedEventHandler handler = PropertyChanged; if( handler != null ) { handler( this, new PropertyChangedEventArgs( "SavedLayouts" ) ); } } } And finally, the layout class (abridged): public class Layout { public String Name { get; private set; } } In the output window, I can see the update occurring: System.Windows.Data Warning: 91 : BindingExpression (hash=64564967): Got PropertyChanged event from TickerzModel (hash=43624632) System.Windows.Data Warning: 97 : BindingExpression (hash=64564967): GetValue at level 0 from TickerzModel (hash=43624632) using RuntimePropertyInfo(SavedLayouts): List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 76 : BindingExpression (hash=64564967): TransferValue - got raw value List`1 (hash=16951421 Count=11) System.Windows.Data Warning: 85 : BindingExpression (hash=64564967): TransferValue - using final value List`1 (hash=16951421 Count=11) But I get do not get this 11th item in the ComboBox. Any ideas?

  • Exception showing a erroneous web page in a WPF frame

    - by H4mm3rHead
    I have a small application where i need to navigate to an url, I use this method to get the Frame: public override System.Windows.UIElement GetPage(System.Windows.UIElement container) { XmlDocument doc = new XmlDocument(); doc.Load(Location); string webSiteUrl = doc.SelectSingleNode("website").InnerText; Frame newFrame = new Frame(); if (!webSiteUrl.StartsWith("http://")) { webSiteUrl = "http://" + webSiteUrl; } newFrame.Source = new Uri(webSiteUrl); return newFrame; } My problem is now that the page im trying to show generates a error (or so i think), when i load the page in a browser it never fully loads, keeps saying "loading1 element" in the load bar and the green progress line (IE 8) keeps showing.

  • Forcing Arrange in a Custom WPF Canvas

    - by Alex Marshall
    Hello, I'm working on a project that involves creating a custom graphical editor. The graphical editor has multiple tabs, and I want to create a preview function that will show a popup with Bitmap previews of the content of each of the tabs. However, the problem I'm running into is that the content for each of the tabs must be arranged before a proper preview can be generated for it. This means going into each of the tabs to ensure that they're rendered and arranged. Then, and only then, do the previews get properly generated, otherwise the previews have a size of 0x0. Does anybody know how to force an arrange of a content control so that I can get a properly sized preview generated ?

  • navigate all items in a wpf tree view

    - by Brian Leahy
    I want to be able to traverse the visual ui tree looking for an element with an ID bound to the visual element's Tag property. I'm wondering how i do this. Controls don't have children to traverse. I started using LogicalTreeHelper.GetChildren, which seems to work as intended, up until i hit a TreeView control... then LogicalTreeHelper.GetChildren doesnt return any children. Note: the purpose is to find the visual UI element that corresponds to the data item. That is, given an ID of the item, Go find the UI element displaying it. Edit: I am apparently am not explaining this well enough. I am binding some data objects to a TreeView control and then wanting to select a specific item programaticly given that business object's ID. I dont see why it's so hard to travers the visual tree and find the element i want, as the data object's ID is in the Tag property of the appropriate visual element. I'm using Mole and I am able to find the UI element with the appropriate ID in it's Tag. I just cannot find the visual element in code. LogicalTreeHelper does not traverse any items in the tree. Neither does ItemContainerGenerator.ContainerFromItem retrieve anything for items in the tree view.
