  • C# WPF Paginator printer ignoring user's printer selection

    - by Anders
    I am using the following code in my project. The print dialog shows, but it always prints on the default printer regardless of the user's selection. I have read similar topics but none of them seem to use the SerializerWriterCollator. What is the problem? PrintQueue printQueue = LocalPrintServer.GetDefaultPrintQueue(); XpsDocumentWriter xpsWriter = PrintQueue.CreateXpsDocumentWriter(printQueue); SerializerWriterCollator batchPrinter = xpsWriter.CreateVisualsCollator(); var printDialog = new PrintDialog(); if (printDialog.ShowDialog() == true) { PrintTicket ticket = printDialog.PrintTicket; ticket.PageOrientation = PageOrientation.Landscape; var paginator1 = new PagePrinter(winchFlightsCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), winchFlights); var paginator2 = new PagePrinter(tugFlightCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), tugFlights); var paginator3 = new PagePrinter(selfFlightCount, new Size(printDialog.PrintableAreaWidth, printDialog.PrintableAreaHeight), selfFlights); batchPrinter.BeginBatchWrite(); for (int i = 0; i < paginator1.PageCount; i++) { batchPrinter.Write(paginator1.GetPage(i).Visual, ticket); } for (int i = 0; i < paginator2.PageCount; i++) { batchPrinter.Write(paginator2.GetPage(i).Visual, ticket); } for (int i = 0; i < paginator3.PageCount; i++) { batchPrinter.Write(paginator3.GetPage(i).Visual, ticket); } batchPrinter.EndBatchWrite(); } }

  • WPF: Exception if i add a eventhandler to a MenuItem (in a ListBox)

    - by user437899
    Hi, i wanted a contextmenu for my ListBoxItems. So i created this: <ListBox Name="listBoxName"> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding UserName}" /> </DataTemplate> </ListBox.ItemTemplate> <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="View" Name="MenuItemView" /> </ContextMenu> </Setter.Value> </Setter> </Style> </ListBox.ItemContainerStyle> </ListBox> This works great. I have the contextmenu for all items, but if i want to add a click-eventhandler to the menuitem, like this: <MenuItem Header="View" Name="MenuItemView" Click="MenuItemView_Click" /> I get a XamlParseException when the window is created. InnerException: The Object System.Windows.Controls.MenuItem cannot be converted to type System.Windows.Controls.Grid It throws only the exception if i add a event-handler. The event-method is empty.

  • WPF ComboBox ControlTemplate Background problem

    - by PaN1C_Showt1Me
    This is an example of a ComboBox's ControlTemplate. CLICK HERE I've tried to set the Background / add a trigger to change the background when the ComboBox is focused (with a tab key for example), both without success. I don't even understand why it isn't included by default ! (compared to the original generic template)

  • WPF - Pausing the UI Thread?

    - by Rachel
    I have a tab control with draggable tabs. When the mouse is released it removes the selected tab from the tabControl and adds it to its new location. My problem is that the TabControl draws itself after removing the tab, and then again when adding the tab so there is a very noticeable flicker that shows the tab behind the tab being moved. Is there a way I can pause the UI thread so the tab control does not redraw until both the Remove and the Insert operations finish? Or perhaps some other alternative way of rearranging the tab items? The Drag/Drop operation exists in a separate code file as an Attached Property

    Struggling with styling the mouse over for a button ... I have managed to style the button (solid red), but I would like for it to change to solid black whenever a mouse over occurs.

  • WPF Template: AdornedElement not showing!

    - by Tau Sick
    I want to add some elements to a TextBox by using a Template with the extra elements and the original TextBox inserted in the right spot. I'm trying to use the AdornedElementPlaceholder just like you would do when making a Validation.ErrorTemplate But the AdornedElement is not showing up. I have simplified the example as much as possible: <TextBox Text="Border me with my Template"> <TextBox.Template> <ControlTemplate TargetType="{x:Type TextBox}"> <Border BorderBrush="Green" BorderThickness="1"> <AdornedElementPlaceholder/> </Border> </ControlTemplate> </TextBox.Template> </TextBox> The result is just a green box around the space that should be my textbox!

  • Multiline for WPF TextBox

    - by baron
    I am developing a app for sending some feedback. Basically i'm trying to make a TextBox for comments, but i'm used to the WinForms MultiLine=true. I've set MinLines to 3, which is getting there, but preferably i'd like if user is able to type wherever in this block, like press enter and do dot points sort of thing - like: - Item 1 blah - Item 2 blahlb lahbvl d But at the moment the text all stays on one line. - Item 1 blah - Item 2 blahb blahb blah This comments will then help fill the body of an email which is sent. It may be pointless if I can't easily keep the same formatting when putting this string into the email body string (so that it looks like it does when sent as it does when typed). Can I achieve what I'm after or do I have to leave it as all text on one line?

  • WPF passing the Int argument to a data object provider method

    - by SAD
    Hi, I'm trying to produce a master/detail datagrid view. I'm using object data providers. Now I have seen many examples when the argument of a method for returning the records for the detail view is a string, like in this example: <!-- the orders datasource --> <ObjectDataProvider x:Key="OrdersDataProvider" ObjectType="{x:Type local:OrdersDataProvider}"/> <ObjectDataProvider x:Key="Orders" MethodName="GetOrdersByCustomer" ObjectInstance="{StaticResource OrdersDataProvider}" > <ObjectDataProvider.MethodParameters> <x:Static Member="system:String.Empty"/> </ObjectDataProvider.MethodParameters> </ObjectDataProvider> But in my case, the argument that I want to pass is the int ID not the string. Can I still somehow use the object data provider to return all the records from the database for the detail view if the argument passed to a method has to be an int? How could it be implemented in MVVM? Thanks a lot for any advice1

  • WPF: Copy Property to Clipboard

    - by Phil Sandler
    I have a string property in my ViewModel/Datacontext and want a simple button that copies its contents to the clipboard. Is this possible to do from XAML, or I do I need to handle the button click event (or use an ICommand) to accomplish this? I thought the following would work, but my button is always greyed out: <Button Width="100" Content="Copy" Command="ApplicationCommands.Copy" CommandTarget="{Binding MyStringProperty}"/>

  • Loading a WPF Window without showing it

    - by svick
    I create a global hot key to show a window by PInvoking RegisterHotKey(). But to do this I need that window's HWND, which doesn't exist until the window is loaded, that means shown for the first time. But I don't want to show the window before I can set the hot key. Is there a way to create a HWND for that window that is invisible to the user?

  • WPF WebBrowser, unable to run Javascript and applet in Popups windows

  • WPF - databinding ObservableCollection CollectionChanged event?

    - by e0eight
    Hi, I have an observable collection implemented in my user control which indicates states of a device. Based on the collection change, the user control is to trigger animations(subscribe to collectionchanged event). The observable collection is implemented as a dependency property. In the application, I data bind the device states to the user control observableCollection using one-way databinding. When a new state is added in the application, I can see the ObservableCollection in the user control is updated. However, the CollectionChanged event never got fired, so no animations. Does anyone has an idea why this is so? Thank you in advance.

  • WPF Notify changes on object

    - by Erik Z
    I have a gridview were I define some columns, like this... <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding MyProp}" /> </DataTemplate> </GridViewColumn.CellTemplate> I bind my gridview to a collection and implemts INotifyPropertyChanged in the property MyProp. This works well and any changes of MyProp are reflected to the gridview. If I add another column that is bound to the object itself I dont get any notifications/updates. My code... <GridViewColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Converter={StaticResource myConverter}}"/> </DataTemplate> </GridViewColumn.CellTemplate> I think I need something like INotifyPropertyChanged for the object but I have no idea how to do this. Any suggestions?

  • WPF ListView in GridView mode Highlighting problem

    - by xenik
    While reskining GridView (ListView with more columns), I ran into a problem, that I couldn't change the color of the Highlighted row. I searched the internet and found out, that adding this can help. <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent" /> <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="Transparent" /> This solved the issue for some people but it didnt help me. The Highlight color was still in system default. I finally managed to change the color of the selected row, but the highlight is still visible around the border of the row plus i need to get rid of the Highlight in the ColumnHeaders. Heres the code, where my approach doesn't work. sth sthelse

  • Memory leak with WPF & ItemsControl (VB.NET)

    - by Matt H.
    I have an ItemsControl that uses a DataTemplate to display properties in my customClass that implements INotifyPropertyChanged... Pretty straightforward... Some items in the DataTemplate use CommandBindings (such as buttons), and a few have some code-behind (yuck). When I empty the ItemsControl and set all instances of customClass = Nothing , no memory is released from my program. This becomes a problem pretty quickly! Any idea where I should start looking? I've even gone so far as to completely traverse the visual tree of each DataTemplate instance and set each Visual = Nothing. I'm not really if that's supposed to have any effect though.

  • WPF: Order of stretch sizing

    - by RFBoilers
    I'm creating a modal dialog window which contains three essential parts: a TextBlock containing instructions, a ContentControl for the dialog panel, and a ContentControl for the dialog buttons. Each of these parts are contained in a separate Grid row. I have some specific constraints when it comes to how the dialog should be sized. The issue I'm having is with the instructions TextBlock. I want the instructions to be as wide as the ContentControl for the dialog panel. The instructions should then wrap and grow vertically as needed. Should the instructions not be able to grow vertically, then it should begin to grow horizontally. Getting the instructions to be the width of the ContentControl and grow vertically was simple. The part I can't seem to figure out is how to get it to grow horizontally when out of vertical space. My initial thought was to create a class that extends TextBlock and override MeasureOverride. However, that method is sealed. Currently, I'm playing with the idea of have the dialog Window override MeasureOverride to calculate the available size for the instructions block. Am I missing a much simpler way of accomplishing this? Does anyone have any better ideas than this? Messing with MeasureOverride seems like it will be a lot of work. Here is some sample code to give you a general idea of how the dialog is laid out: <Window x:Class="Dialogs.DialogWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="dialogWindow" ShowInTaskbar="False" WindowStyle="None" AllowsTransparency="True" Background="Transparent" ResizeMode="NoResize" SizeToContent="WidthAndHeight" WindowStartupLocation="CenterScreen"> <Border Style="{StaticResource WindowBorderStyle}" Margin="15"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <TextBlock Margin="25,5" VerticalAlignment="Top" HorizontalAlignment="Left" Text="{Binding Instructions}" TextWrapping="Wrap" Width="{Binding ElementName=panelContentControl, Path=ActualWidth, Mode=OneWay}"/> <ContentControl x:Name="panelContentControl" Grid.Row="1" Margin="25,5" Content="{Binding PanelContent}"/> <ContentControl x:Name="buttonsContentControl" Grid.Row="2" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="25,5" Content="{Binding ButtonsContent}"/> </Grid> </Border> </Window>
