  • Loading an external image via XAML code in WPF?

    - by Mohammad
    I have an image lock.png beside of my WPF exe file in the images folder. Now, I'm gonna load it into the WPF Project as an image, I've used the following XAML code: <Image Stretch="Fill" Source="pack://siteoforigin:,,,/images/lock.png" /> It works, but Expression Blend or Visual Studio doesn't show it when I'm working on the project. How can we show external images in these situations?

  • Is there a way to do simple calculations in a xaml element binding statement other than using a conv

    - by Jonathan Websdale
    In XAML I want to bind the height of one element to be half the height of another element. Is there a way to do this that doesn't involve writing a converter in the code-behind? Example:- What I've got... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=Height, Converter={StaticResource MyHalfHeightConverter}}"/> What I'd like... <Button Name="RemoveButton" Content="Remove Stage" Width="100" Height="{Binding ElementName=AddButton, Path=(Height / 2.0)}"/>

  • In pure XAML, is it possible to get a Line to align to part of a Grid?

    - by Jeff Wilcox
    Is it possible to create a Line in XAML (without any C# code behind) to align a line inside of a layout container such as a Grid? I'd like to effectively have: <Grid> <Line StrokeThickness="1" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Stroke="Red"/> </Grid> I need to use StrokeDashArray and StrokeDashOffset, otherwise I would just use a Border control with the BorderThickness set to "0,0,0,1"... Thanks for any ideas!

  • Do you have any recommendations on Blend/XAML books/tutorials for designers?

    - by Lenik
    There are a lot of WPF resources that are aiming developers. We are trying to get our designer up-to speed, and I have been researching some of the options on the market. The only two reasonable options that I found were "Expression Blend Unleashed" and "APress Foundation Expression Blend 2 Building Applications in WPF and SilverLight". Do people have any recommendations on blend/xaml books/tutorials for designers?

  • Using NavigationService without XAML files

    - by UnclePaul
    I'm trying to create some pages in my Windows Phone application without the use of any XAML. Everything is working, however, I'm failing to use NavigationService/ Journal with this approach and all my attempts to utilize it are answered by the usual "No XAML was found at the location {0}'" response. Yes, I can add an almost empty XAML file to get everything working, but is this kind of boiler plate code really necessary? Is it maybe possible to use the UriMapping to map certain Uris to specific classes instead of *.xaml files?

  • Is there a way to chain multiple value converters in XAML?

    - by Mal Ross
    I've got a situation in which I need to show an integer value, bound to a property on my data context, after putting it through two separate conversions: Reverse the value within a range (e.g. range is 1 to 100; value in datacontext is 90; user sees value of 10) convert the number to a string I realise I could do both steps by creating my own converter (that implements IValueConverter). However, I've already got a separate value converter that does just the first step, and the second step is covered by Int32Converter. Is there a way I can chain these two existing classes in XAML without having to create a further class that aggregates them? If I need to clarify any of this, please let me know. :) Thanks.

  • What are the real-world benefits of declarative-UI languages such as XAML and QML?

    - by Stu Mackellar
    I'm currently evaluating QtQuick (Qt User Interface Creation Kit) which will be released as part of Qt 4.7. QML is the JavaScript-based declarative language behind QtQuick. It seems to be a very powerful concept, but I'm wondering if anybody that's made extensive use of other, more mature declarative-UI languages like XAML in WPF or Silverlight can give any insight into the real-world benefits that can be gained from this style of programming. Various advantages are often cited: Speed of development Forces separation between presentation and logic Better integration between coders and designers UI changes don't require re-compilation Also, are there any downsides? A few potential areas of concern spring to mind: Execution speed Memory usage Added complexity Are there any other considerations that should be taken into account?

  • How to set Height of items in XAML so they always occupy the same proportion of available space in p

    - by aoven
    I have an ItemsControl with the following ItemTemplate: <DataTemplate x:Key="myItemTemplate"> <TextBlock Height="???" Text="{Binding Path=Description}" /> </DataTemplate> My question is, how do I set the Height of the TextBlock in the template so that it automatically assumes ItemsControl.Height div ItemsCount amount of vertical space? When there's only one item, I'd like it to be the full height of container, when there're two, each should be half the size, and so on. If possible, I'd prefer to do this completely in XAML to keep my ViewModel clean of UI logic.

  • Is there any way to create a dynamic list of strings (based on language) in XAML?

    - by Xin
    Just wondering if it is possible to dynamically create a list of strings in XAML based on language/culture? Say if user logs in as an English user it shows Client Name, Order Number... and if user logs in as a Polish user it shows Nazwa klienta, Numer zamówienia instead? I only know the hardcoded one like below: <System_Collections_Generic:List`1 x:Key="columnNameList"> <System:String>Client Name</System:String> <System:String>Order Number</System:String> <System:String>Date</System:String> </System_Collections_Generic:List`1>

  • In XAML is there way to bind key press and key release to specific commands?

    - by Ashley Davis
    In my application I have keys that bound to commands using the KeyBinding class. The command is executed when the key is pressed and released. I have a special case where I want to bind separate commands to the pressed action and to the released action. For example when the space key is pressed I want my app to run a command to enter a special mode. Then when the space key is released I want to run another command to exit that special mode. Currently I do this by manually handling the KeyUp and KeyDown events. Is there anyway to execute commands for pressed and released purely in XAML?

  • How does the VS XAML designer know what to auto-populate certain values with?

    - by Pwninstein
    <Button Name="MyButton" Content="Test" FontStyle="Italic" /> In the above XAML definition of a button, the FontStyle property is set to Italic. The designer is somehow able to populate a list for me to choose from when I hit the = sign. How is this achieved? Before you answer, consider that the FontStyle property is, appropriately enough, of type FontStyle (which is a struct). It's not an enumeration, which would be trivial for VS to list out at design time, so how are the valid list of options chosen to be displayed? There is also a completely separate FontStyles class which contains three static fields, Italic, Normal, and Oblique which just so happen to be the three items VS provides in the drop down list. Is there some mapping going on behind the scenes between the FontStyle struct and FontStyles class, because I've looked in many places in both the object browser and in .NET Reflector and couldn't determine anything from either. Thanks!! I NEED to know!* *Not really, but it would be nice to :)

  • How can I bind a LinkedList as ItemSource to ListView in WPF XAML?

    - by Jonas
    I'm learning WPF and would like to have a collection similar to a LinkedList, to where I can add and remove strings. And I want to have a ListView that listen to that collection with databinding. How can I do bind a simple list collection to a ListView in XAML? My idea (not working) is something like this: <Window ...> <Window.Resources> <LinkedList x:Key="myList"></LinkedList> <Window.Resources> <Grid> <ListView Height="100" HorizontalAlignment="Left" Margin="88,134,0,0" Name="listView1" VerticalAlignment="Top" Width="120" ItemsSource="{Binding Source={StaticResource myList}}"/> </Grid> </Window>

  • In WPF XAML how can I concatenate 2 constants so I can use pre-define paths?

    - by toaster24
    I'm new to XAML, so presume I'm missing something simple. I want to replace the path part of the source path with a c# constant for easier path management, for example I have: <Image Source="/Images/Themes/Buttons/MyPicture.png" /> and in another class I have my constant defined: public static readonly string UriImagesButtons = "/Images/Big/PNG/"; I want to have something along the lines of: <Image Source="{static:UriImagesButtons + MyPicture.png}" /> This means that I can change the path globally at a stroke if the need arises. What's the syntax to do this?

  • how do you set a property of a control to an address of a function in xaml?

    - by ambog36
    Hi, I have a control that has a "Filter" property that expects a function that defines how the contents of the control should be filtered. so far i am setting the filter in code behind as such: MyControl.Filter = AddressOf Filters.MyFilter In this example MyFilter is a shared function in the Filters class with the following signature: Public Shared Function MyFilter(ByVal obj As Object, ByVal text As String) As Boolean I would like to set this in xaml. I was thinking of setting the Filters.MyFilter as a static resource and setting it that way: ...Filter="{StaticResource myFilter}"/ but i cant set Filters.MyFilter as a static resource. Any ideas on how to achieve this? Thanks,

  • Error when adding code behind for Silverlight resource dictionary: AG_E_PARSER_BAD_TYPE

    - by rwwilden
    Hi, It should be possible to add a code behind file for a resource dictionary in Silverlight, but I keep getting the same error, thrown from the InitializeComponent method of my App.xaml constructor: XamlParseException: AG_E_PARSER_BAD_TYPE. The resource dictionary xaml file looks like this: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Celerior.Annapurna.SL.ProvisiorResourceDictionary" x:ClassModifier="public"> ... </ResourceDictionary> If I remove the x:Class attribute everything works fine again (of course, I double-checked the class name and it's correct). My App.xaml file isn't really exciting and just contains a reference to the resource dictionary: <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Celerior.Annapurna.SL.App"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="ProvisiorResourceDictionary.xaml"/> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> What am I doing wrong? Kind regards, Ronald Wildenberg

  • Aliasing Resources (WPF)

    - by Noldorin
    I am trying to alias a resource in XAML, as follows: <UserControl.Resources> <StaticResourceExtension x:Key="newName" ResourceKey="oldName"/> </UserControl.Resources> oldName simply refers to a resource of type Image, defined in App.xaml. As far as I understand, this is the correct way to do this, and should work fine. However, the XAML code gives me the superbly unhelpful error: "The application XAML file failed to load. Fix errors in the application XAML before opening other XAML files." This appears when I hover over the StaticResourceExtension line in the code (which has a squiggly underline). Several other errors are generated in the actual Error List, but seem to be fairly irrelevant and nonsenical (such messages as "The name 'InitializeComponent' does not exist in the current context"), as they all disappear when the line is removed. I'm completely stumped here. Why is WPF complaining about this code? Any ideas as to a resolution please? Note: I'm using WPF in .NET 3.5 SP1. Update 1: I should clairfy that I do receive compiler errors (the aforementioned messages in the Error List), so it's not just a designer problem. Update 2: Here's the relevant code in full... In App.xaml (under Application.Resource): <Image x:Key="bulletArrowUp" Source="Images/Icons/bullet_arrow_up.png" Stretch="None"/> <Image x:Key="bulletArrowDown" Source="Images/Icons/bullet_arrow_down.png" Stretch="None"/> And in MyUserControl.xaml (under UserControl.Resources): <StaticResourceExtension x:Key="columnHeaderSortUpImage" ResourceKey="bulletArrowUp"/> <StaticResourceExtension x:Key="columnHeaderSortDownImage" ResourceKey="bulletArrowDown"/> These are the lines that generate the errors, of course.

  • Insufferable word wrap in Visual Studio XAML editor - is there any relief for 2010?

    - by DanM
    Just curious if the XAML editor is any better at auto-formatting and wrapping attributes in Visual Studio 2010. Here's how the editor auto wraps attributes in VS 2008: <StackPanel Grid.Row="0" Grid.ColumnSpan="3"> <StackPanel Orientation="Horizontal"> <TextBlock VerticalAlignment="Center" FontWeight="Bold" Text="Current User:" /> <ComboBox x:Name="_usersComboBox" Margin="5,0,0,0" Width="200" ItemsSource="{Binding Users}" SelectedValuePath="Name" SelectedValue="System Administration"> <ComboBox.ItemTemplate> <DataTemplate> Here's how I'd like the editor to auto wrap attributes: <StackPanel Grid.Row="0" Grid.ColumnSpan="3"> <StackPanel Orientation="Horizontal"> <TextBlock VerticalAlignment="Center" FontWeight="Bold" Text="Current User:" /> <ComboBox x:Name="_usersComboBox" Margin="5,0,0,0" Width="200" ItemsSource="{Binding Users}" SelectedValuePath="Name" SelectedValue="System Administration"> <ComboBox.ItemTemplate> <DataTemplate> Does VS 2010 grant my wish?

  • Is it possible to template a template in WPF XAML?

    - by imekon
    Is it possible to use templates within templates? For instance, I have the following two templates: <HierarchicalDataTemplate x:Key="RecursiveTemplate" ItemsSource="{Binding Children}"> <StackPanel Margin="1" Orientation="Horizontal"> <Ellipse Fill="DarkGreen" Width="14" Height="14"/> <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> </StackPanel> </HierarchicalDataTemplate> <HierarchicalDataTemplate x:Key="ContainerTemplate" ItemsSource="{Binding Children}"> <StackPanel Margin="1" Orientation="Horizontal"> <Ellipse Fill="DarkBlue" Width="14" Height="14"/> <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> </StackPanel> </HierarchicalDataTemplate> There's a section of identical XAML: <TextBlock MouseDown="OnTreeMouseDown" TargetUpdated="OnTargetUpdated" Visibility="{Binding Editing, Converter={StaticResource visibilityInverter}}" Margin="5" Text="{Binding Name}"/> <TextBox PreviewKeyDown="OnTreeKeyDown" Visibility="{Binding Editing, Converter={StaticResource visibilityConverter}}" Margin="2" Text="{Binding Name}"/> Is it possible to move that to a resource and refer to it by name, rather than repeat it?

  • What's the best way to handle layout issues with multi-language support in WPF/XAML?

    - by Tim
    I'm creating a standalone WPF app with multi-language support. I've found some great resources (mostly on SO) on how to store and access the strings as needed. This part is pretty straightforward and doable, but I'm fuzzy on how to take care of screen layout issues. I'm using some custom images to skin up my app for buttons, etc. For instance, here's a button with some text within: <Button Canvas.Left="33" Canvas.Top="484" Style="{StaticResource SmallButtonBase}"> <TextBlock FontSize="20" FontWeight="Bold" TextAlignment="Center" FontFamily="Helvetica"> Enter </TextBlock> </Button> Now here is the same button with text from another language: <Button Canvas.Left="33" Canvas.Top="484" Style="{StaticResource SmallButtonBase}"> <TextBlock FontSize="20" FontWeight="Bold" TextAlignment="Center" FontFamily="Helvetica"> Enterenschtein </TextBlock> </Button> So my question is: What is a good method to prevent this "overflow" situation. I'd like to have XAML take care of any font resizing or indenting that is needed automatically so that I don't have to tweak the UI for each language I'm supporting. Any insight is appreciated!
