  • Expandable columns in a datagrid

    - by Jobe
    Im working on a WPF-applications to present and correct large amounts of data. Im about to implement a datagrid containing data from 3 different sources that are populated from external services. To start with I will only populate the grid with data from one source, the master source. However, sometimes an automated validator will trigger a validation warning or error on one cell and the requirement states that the user should be able to view data from the additional 2 sources in columns next to the selected one. Something like this: Standard view: | col1 src1 | col2 src1 | col3 src1 | | | | | | |faulty | | | | | | User want to show data from source 2 and 3 next to the column "col2 src1" like this: | col1 src1 | col2 src1 | col2 src2 | col2 src3 | col3 src1 | | | | | | | | |corrected | | | | | | | | | | and then be able to correct the faulty formatted cell with data from the other 2 soruces, and then collapse the columns again. I am trying to use the mvvm pattern on this one so I have populated the DataGrid with a ListCollectionView so far. The list contains items with properties like this: MyRowItem {string col1, string col2, string col3} I will then have 2 additional collections with items of type like above but from 2 other sources. I have no idea how to implement this functionality and could use some help on the logics. What approach should I head for?

  • Choosing right control for list of items

    - by prostynick
    I am new to WPF and MVVM. In my ViewModel I have collection of items, for example: class Item { string Title {get; set;} string Description {get; set;} } I would like to create a view, so at the beginning I would have: Title1 Title2 Title3 If user click on one of title it will expand to show description, eg: Title1 Description1 Title2 Title3 If user click on other title, there will be two expanded items: Title1 Description1 Title2 Description2 Title3 This is probably very similar to Expander control and maybe I could use it, but I am doing it other way, to learn something new. What control should I use for this purpose? Should that be ItemsControl or maybe ListBox? I imagine, that if I use ItemsControl, I should probably extend my Item class to have something like bool IsExpanded and bind UI item visibility to that value. But maybe I could use ListBox and somehow bind UI item visibility to... Yeah, to what? :) How could I do such a simple thing?

  • NHibernate Performance Optimization | Suggestions invited!!!

    - by user336749
    Hi, I’m facing an issue with NHibernate performance and can you please suggest me some optimizations? Below mentioned is a small summary of my application architecture I have a windows service which is listening to a messaging bus. On receiving a message the service creates an object out of which a property is the received xml snippet and saves the message to the DB (uses NH). There is a WPF UI with a readonly connection to the DB, and on refresh of the UI it displays the objects on the screen. While the UI does a refresh, it retrieves the xml and deserializes it , from which the object’s properties are derived and binded to the screen. For example assume an xml XXX is received by the service, it deserializes the xml , creates the book object and save it to the DB and a property/column is SCHEMA which contains the xml snippet. The UI while refreshed searches all book objects by ID and creates the book objects out of the xml which is being saved (yes, the xml is the constructor param). Now my issue is that the refresh takes more than 2 minutes to display say 50 book objects. I analyzed it using the NHibernate profiler, and found that the time spend within the DB is negligible, however time spent to create the entities is proportionally huge(10ms:1990 ms).I guess it’s due to the fairly huge size of xml snippet and it’s deserialization. My question is, how can I improve the performance. I dispose sessions after every refresh and is not lazy loading (please note that the time spend in DB is negligible). On every refresh it’s possible that all objects are updated by some downstream systems or maybe one of them are updated.Can I implement some sort of caching mechanism in this case? Thanks in advance for any suggestions. Regards, -Mike

  • How to automatically extend the tab control as items are added to it without creating a scroll bar?

    - by MICHELINE
    I am using a WPF user control (tab control) to add tab items dynamically in the simplified code below: .... foreach (string id in ids) { TabControl.Items.Add(CreateTabItem(id)); } private TabItem CreateTabItem(string name) { StackPanel txtBlock = new TextBlock(); txtblock.Text = name; txtBlock.HorizontalAlignment = Horizontalalignment.Center; panel.Children.Add(txtBlock); TabItem item = new TabItem(); item.Header = panel; <SomeControl> control = new <SomeControl>(); item.Content = control; return item; } In the xaml file I specified the following to stack all my tab items to the left column: MinWidth="100" MinHeight="300" TabStripPlacement="Left" How do I make my tab control automatically extending (ie. stretching) its height to show all the tab items as I add them in? For now, I have to manually extend the height of the display window to see all the tab items. Your insights/tips are greatly appreciated. PS: if you know how to make the vertical scroll bar appears (without adding scroll bar to my control) as soon as the tab items exceed the window height, I can settle for that if there are no answers for my original intent.

  • What am I doing wrong with my ItemsControl & databinding?

    - by Joel
    I'm reworking my simple hex editor to practice using what I've recently learned about data binding in WPF. I'm not sure what I'm doing wrong here. As I understand it, for each byte in the collection "backend" (inherits from ObservableCollection), my ItemsControl should apply the DataTemplate under resources. This template is just a textbox with a binding to a value converter. So I'm expecting to see a row of textboxes, each containing a string representation of one byte. When I use this XAML, all I get is a single line of uneditable text, which as far as I can tell doesn't use a textbox. What am I doing wrong? I've pasted my XAML in below, with the irrelevant parts (Menu declaration, schema, etc) removed. <Window ...> <Window.Resources> <local:Backend x:Key="backend" /> <local:ByteConverter x:Key="byteConverter" /> <DataTemplate DataType="byte"> <TextBox Text="{Binding Converter={StaticResource byteConverter}}" /> </DataTemplate> </Window.Resources> <StackPanel> <ItemsControl ItemsSource="{Binding Source={StaticResource backend}}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </StackPanel> </Window>

  • Handling exceptions in Prism 4 modules

    - by marcellscarlett
    I've gone through a number of threads here about this topic with no success. It seems that in the App.xaml.cs of our WPF application, handling DispatcherUnhandledExceptions and AppDomain.CurrentDomain.UnhandledException don't catch everything. In this specific instance we have 7 prism modules. My exception handling code is below (almost identical for UnhandledException): private void OnDispatcherUnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e) { try { var ex = e.Exception.InnerException ?? e.Exception; var logManager = new LogManager(); logManager.Error(ex); if (!EventLog.SourceExists(ex.Source)) EventLog.CreateEventSource(ex.Source, "AppName"); EventLog.WriteEntry(ex.Source, ex.InnerException.ToString()); var emb = new ExceptionMessageBox(ex); emb.ShowDialog(); e.Handled = true; } catch (Exception) { } } The problem seems to be the unhandled exceptions occurring in the modules. They aren't caught by the code above and they cause the application to crash without logging or displaying any sort of message. Does anyone have experience with this?

  • Execute files included in Resource folder

    - by Sumeet Pujari
    In WPF application where I have included some files in resources, I want to execute them on a button click. How do I specify a path in Process.Start(). private void button1_Click_2(object sender, RoutedEventArgs e) { Process.Start("test.txt"); } Or is there any other way? private void button1_Click_2(object sender, RoutedEventArgs e) { string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location) + @"\test.txt"; if (File.Exists(path)) { Process.Start(new ProcessStartInfo(path)); } else { MessageBox.Show("No file found"+path); } I added a message box and it showed No files found. :( EDIT: I Tried to check the path after publishing and this what i got. No File Found With a Path - C:\Users\Administrator\AppData\Local\Apps\2.0... test.txt Before I published the Application I got a path which id No File Found at ..project..\bin\Debug\test.txt which is obvious since my Resource file not included there its Under a Resource Folder and not Debug when i add a test file in debug it open without any problem. Can someone Help throwing some light on this case. EDIT: I want to open a file from Resource directory @ C:\Users\Administrator\Documents\Visual Studio 2010\Projects\FastFix\FastFix\Resources Which would be included in my project when i am going to publish it is going to run as a standalone application without installation.

  • Window manipulation and inctences control

    - by touki
    In my application there are only 2 windows — win_a & win_b, on each of these windows there is button that call another window, e.g. click on btn1 of win_a will call win_b, click on btn2 of win_b will show win_a. Desired behaviour: 1. Only one instance of object is premitted at the same time, e.g. situation, where 2 instances of win_a running at the same time is not permitted. When you click on button that calls windows that already exist this action will only change a focus to needed window. If you call a window that previously had been created, but after this has been closed this action will create a new instance of this window. E.g. there are 2 running windows. you close one of them and after try to call this window back, so related button will create it. How to write it in WPF (XAML + C#). For the moment I wrote a version that can create a lot of instances of the same window (no number of instances control implemented), but I want to see only one instance of the same window, as we can see it in a lot of applications. Example of my code: Window win = new Window(); win.Show(); Thanks.

  • WPF: how to find an element in a datatemplate from an itemscontrol

    - by EV
    Hi, I have the following problem: the application is using the custom itemscontrol called ToolBox. The elements of a toolbox are called toolboxitems and are custom contentcontrol. Now, the toolbox stores a number of images that are retrieved from a database and displayed. For that I use a datatemplate inside the toolbox control. However, when I try to drag and drop the elements, I don't get the image object but the database component. I thought that I should then traverse the structure to find the Image element. here's the code: Toolbox: public class Toolbox : ItemsControl { private Size defaultItemSize = new Size(65, 65); public Size DefaultItemSize { get { return this.defaultItemSize; } set { this.defaultItemSize = value; } } protected override DependencyObject GetContainerForItemOverride() { return new ToolboxItem(); } protected override bool IsItemItsOwnContainerOverride(object item) { return (item is ToolboxItem); } } ToolBoxItem: public class ToolboxItem : ContentControl { private Point? dragStartPoint = null; static ToolboxItem() { FrameworkElement.DefaultStyleKeyProperty.OverrideMetadata(typeof(ToolboxItem), new FrameworkPropertyMetadata(typeof(ToolboxItem))); } protected override void OnPreviewMouseDown(MouseButtonEventArgs e) { base.OnPreviewMouseDown(e); this.dragStartPoint = new Point?(e.GetPosition(this)); } public String url { get; private set; } protected override void OnMouseMove(MouseEventArgs e) { base.OnMouseMove(e); if (e.LeftButton != MouseButtonState.Pressed) { this.dragStartPoint = null; } if (this.dragStartPoint.HasValue) { Point position = e.GetPosition(this); if ((SystemParameters.MinimumHorizontalDragDistance <= Math.Abs((double)(position.X - this.dragStartPoint.Value.X))) || (SystemParameters.MinimumVerticalDragDistance <= Math.Abs((double)(position.Y - this.dragStartPoint.Value.Y)))) { string xamlString = XamlWriter.Save(this.Content); MessageBoxResult result = MessageBox.Show(xamlString); DataObject dataObject = new DataObject("DESIGNER_ITEM", xamlString); if (dataObject != null) { DragDrop.DoDragDrop(this, dataObject, DragDropEffects.Copy); } } e.Handled = true; } } private childItem FindVisualChild<childItem>(DependencyObject obj) where childItem : DependencyObject { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++) { DependencyObject child = VisualTreeHelper.GetChild(obj, i); if (child != null && child is childItem) return (childItem)child; else { childItem childOfChild = FindVisualChild<childItem>(child); if (childOfChild != null) return childOfChild; } } return null; } } here is the xaml file for ToolBox and toolbox item: <Style TargetType="{x:Type s:ToolboxItem}"> <Setter Property="Control.Padding" Value="5" /> <Setter Property="ContentControl.HorizontalContentAlignment" Value="Stretch" /> <Setter Property="ContentControl.VerticalContentAlignment" Value="Stretch" /> <Setter Property="ToolTip" Value="{Binding ToolTip}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type s:ToolboxItem}"> <Grid> <Rectangle Name="Border" StrokeThickness="1" StrokeDashArray="2" Fill="Transparent" SnapsToDevicePixels="true" /> <ContentPresenter Content="{TemplateBinding ContentControl.Content}" Margin="{TemplateBinding Padding}" SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" ContentTemplate="{TemplateBinding ContentTemplate}"/> </Grid> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter TargetName="Border" Property="Stroke" Value="Gray" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="{x:Type s:Toolbox}"> <Setter Property="SnapsToDevicePixels" Value="true" /> <Setter Property="Focusable" Value="False" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate> <Border BorderThickness="{TemplateBinding Border.BorderThickness}" Padding="{TemplateBinding Control.Padding}" BorderBrush="{TemplateBinding Border.BorderBrush}" Background="{TemplateBinding Panel.Background}" SnapsToDevicePixels="True"> <ScrollViewer VerticalScrollBarVisibility="Auto"> <ItemsPresenter SnapsToDevicePixels="{TemplateBinding UIElement.SnapsToDevicePixels}" /> </ScrollViewer> </Border> </ControlTemplate> </Setter.Value> </Setter> <Setter Property="ItemsPanel"> <Setter.Value> <ItemsPanelTemplate> <WrapPanel Margin="0,5,0,5" ItemHeight="{Binding Path=DefaultItemSize.Height, RelativeSource={RelativeSource AncestorType=s:Toolbox}}" ItemWidth="{Binding Path=DefaultItemSize.Width, RelativeSource={RelativeSource AncestorType=s:Toolbox}}" /> </ItemsPanelTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> Example usage: <Toolbox x:Name="NewLibrary" DefaultItemSize="55,55" ItemsSource="{Binding}" > <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <Image Source="{Binding Path=url}" /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </Toolbox> The object that I get is a database object. When using a static resource I get the Image object. How to retrieve this Image object from a datatemplate? I though that I could use this tutorial: http://msdn.microsoft.com/en-us/library/bb613579.aspx But it does not seem to solve the problem. Could anyone suggest a solution? Thanks!

  • Microsoft WPF Certification

    - by Carlo
    I'm seriously thinking about getting this certification. I already contacted Apex InfoTech and they gave me prices and everything. This is the description of the course. It lasts for 3 days, and the price is $1,495. What do you guys think, is it worth it? I've already been using WPF for a a bit more than a year, but I think a little Microsoft Certification badge would be good for my business card and resume. Let me know what you think. Thanks!

  • Silverlight MVVM conversion from WPF

    - by IrishJoker
    I was reading this article - http://msdn.microsoft.com/en-us/magazine/dd419663.aspx And I came across this piece of code in the WPF Demo application that came with the article. This template applies a CustomerView to an instance of the CustomerViewModel class shown in the main window. <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView /> </DataTemplate> I substituted the angle brackets for square brackets - not sure how to post them. The code is in the MainWindowResourses.xaml and the code starts on line 19. Anyone know how I can do this in Silverlight ?? We don't have the DataType and I need to be able to tell the app that this View is associated with this ViewModel - so I can create a tab control with different view like the demo app. Cheers, EC

  • Get XAML from WPF Custom RichTextFormat

    - by Erika
    I've looked at other posts, but i cant seem to find something that works. I have a custom control WPF RichTextBox and would like to obtain the XAML from this control. I have tried the following //rt is the name of this particular custom richtextbox TextRange range = new TextRange(rt.Document.ContentStart, rt.Document.ContentEnd); MemoryStream stream = new MemoryStream(); range.Save(stream, DataFormats.Xaml); string xamlText = Encoding.UTF8.GetString(stream.ToArray()); return xamlText; but this doesnt seem to work :s I can access the rt.Document.Content start etc but it seems to crash there "Object Reference not set to instance of an object". I am using the richtextbox directly from the .xaml.cs so it should be initiated and so on :s. Any Ideas or other ways to get the XAML from a richtextbox pls? (i'm requiring the XAML cos i actually want to get the HTML.. if theres some other direct manner perhaps?)

  • Creating an installer with WPF forms, packaged files and custom setup actions

    - by RodH257
    I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

  • wpf c# media player questions

    - by Sankar
    I'm making a media player in wpf using c#. I had 3 questions. 1) I tried making a seeker XAML: <Slider Name="timelineSlider" Margin="40,91,26,0" ValueChanged="SeekToMediaPosition" Height="32" VerticalAlignment="Top" /> Code: private void Element_MediaOpened(object sender, EventArgs e) { timelineSlider.Maximum = ply.NaturalDuration.TimeSpan.TotalMilliseconds; } private void SeekToMediaPosition(object sender, RoutedPropertyChangedEventArgs<double> e) { int SliderValue = (int)timelineSlider.Value; TimeSpan ts = new TimeSpan(SliderValue, SliderValue, SliderValue, SliderValue, SliderValue); ply.Position = ts; } When I run the program, I open the mp3 and play it but the seeker won't move. When I click on the seeker to move it to a certain position, the song stops playing but the seeker moves. What's the problem and how do I fix it? How do I create a volume increase/decrease bar? How can I open several mp3s and queue them up like a playlist? Thank you

  • Binding list of objects to WPF ListView

    - by Dave Colwell
    Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

  • Real winforms/wpf projects which use MVC, MVP, MVVM

    - by Belousov Pavel
    Hello everybody, I have looked some videos and read some articles about MVC, MVP, MVVM. I think, that I understood basic principles and differences. But it seems to me that samples in articles and videos are very easy. I think that it's easy to learn how to apply these patterns when you can look on some projects. So I'd like to look on real projects(Winforms/WPF), which use MVC, MVP or MVVM. Could you provide me links to sources of such projects? (If it is open source) It will be great if projects will have unit tests for Controller/Presenter/ViewModel, because it's one of my problem when I develop applications. Thanks in advance.

    Hi All, I have an application that uses WPF Composite, and I have an issue. I've got a big database that is attached to the application and I need it exposed to different modules as part of the application. What is the best way to expose my Entity Framework model to all my different modules and views inside them? Do I have one EF model or a separate one for each module and then only the tables that each module needs. The only problem being that some tables have a relationship and will have different views and those views will be in different modules. Any ideas how to resolve this?

  • Uri for bitmap in subfolder (c# wpf)

To reference the image I use: Uri uri = new Uri("pack://application:,,,/assemblyName;Component/myIcon.png"); BitmapImage(uri) If I add the png directly under the csproj file (with its properties BuildAction=Resource) then it works fine. But I want to move it to a subfolder under the csproj. Another SO question asked about bitmaps\uri's (857732) and an answer linked to this msdn.

    I am attempting to collaborate on a C#/WPF project with another developer remotely via e-mail; and although the code compiles perfectly when it leaves, my collaborator has not been able to compile the code on his side. We are both using VS 2008 Version 9. This is the first time trying to work with someone else on an application and I was hoping that someone would advise me if there are any suggestions to obtain and ensure compatibility between the two of us? Additionally, is there a recommended procedure to prepare the solution for shipment (ie. just zip up the solution folder? export the application? etc.)? Thanks very much.

  • Need additional help with binding multiple CommandParameters using MultiBinding

    - by Dave
    I need to have a command handler for a ToggleButton that can take multiple parameters, namely the IsChecked property of said ToggleButton, along with a constant value, which could be a string, byte, int... doesn't matter. I found this great question on SO and followed the answer's link and read up on MultiBinding and IMultiValueConverter. It went really smoothly until I had to write the MultiBinding, when I realized that I also need to pass a constant value and couldn't do something like <Binding Value="1" /> I then came across another similar question that Kent Boogaart answered, and then I started to think about ways that I could get around this. One possible way is to not use MVVM and simply add the Tag property to my ToggleButton, in which case my MultiBinding would look like this: <MultiBinding Converter="{StaticResource MyConverter}"> <MultiBinding.Bindings> <Binding Path="IsChecked" /> <Binding Path="Tag" /> </MultiBinding.Bindings> </MultiBinding> Kent had made a comment along the lines of, "if you're using MVVM you should be able to get around this issue". However, I'm not sure that's an option for me, even though I have adopted MVVM as my WPF pattern of necessity choice. The reason why I say this is that I have wayyyy more than one ToggleButton in the UserControl, and each of the ToggleButtons' Commands need to call the same function. But since they are ToggleButtons, I can't use the property bound to IsChecked in the ViewModel, because I don't know which one was last clicked. I suppose I could add another private property to keep track of this, but it seems a little silly. As far as the constant goes, I could probably get rid of this if I did the tracking idea, but not sure of any other way to get around it. Does anyone have good suggestions for me here? :) EDIT -- ok, so I need to update my bindings, which still don't work quite right: <ToggleButton Tag="1" Command="{Binding MyCommand}" Style="{StaticResource PassFailToggleButtonStyle}" HorizontalContentAlignment="Center" Background="Transparent" BorderBrush="Transparent" BorderThickness="0"> <ToggleButton.CommandParameter> <MultiBinding Converter="{StaticResource MyConverter}"> <MultiBinding.Bindings> <Binding Path="IsChecked" RelativeSource="{RelativeSource Mode=Self}" /> <Binding Path="Tag" RelativeSource="{RelativeSource Mode=Self}" /> </MultiBinding.Bindings> </MultiBinding> </ToggleButton.CommandParameter> </ToggleButton> IsChecked was working, but not Tag. I just realized that Tag is a string... duh. It's working now! The key was to use a RelativeSource of Self.
