  • WPF Custom Control containing a List of Objects

    - by Cecile
    Hi, I have an object Trip in my object model containing a list of Nodes (e.g. NodeName, StartDate and EndDate) and I am trying to build a Custom control in WPF that draws list of rectangles: one for each Node contained in the Trip object (based on StartDate en EndDate) Would you have any hint on how the Custom Control should be structured so that I can bind a Trip object to it and draw the rectangles properly, please?

  • Underlining 3 words at a time in WPF

    - by user102533
    In WPF, how would I do the following: Every x milliseconds, underline 3 words at a time. After x milliseconds, underline the next 3 words. Every x milliseconds, have 3 words appear and disappear from the window? If I were to use Windows Forms, is there still a way of doing (1) and (2) above? Thank you

  • Looking for a chart of Wpf Bindings

    - by BSalita
    I'm probably typical in being bewildered by the many syntaxes of Wpf binding. Does anyone know of a chart that lays out all the possibilities. Across one axis is all the variations of binding syntaxes (Static, Dynamic, Self, ...), the other axis are all the variations of scoping and type. The intersection of the axis show an example. Surely someone, some author has done this, eh?

  • WPF Application with Database.

    - by mike
    Hi, i would like to or need to use a database for my wpf project. It has to store "person" "team" "goals" and maybe 2 more things, nothing very big. Ive already used (worked) with databases in java / php (postgresql), but is there maybe an "easier" way to store the things.. i mean if the db is going to be big than i could use (postgre or mysql), but this one would be small.

  • C# WPF XAML Loading

    - by user3713589
    Hi I'd like to inquire on how i can load a WPF Xaml into code so that I can change the values of the attributes of some XAML elements and output it by creating another XAML files. This is so that I can output the same file with values dynamically input by the user. the XamlReader.Load() method cannot be used; it will throw an exception (because they are unable to recognise Window as the root element). I'm using VS2013 and C#.

  • Best approch for creating Base control

    - by akjoshi
    Hi, I am looking for a solution for this scenario - I need to implement a feature to allow user to add various controls to canvas(WPF, custom and third party ) and then select any one of them and modify some properties in property grid(changes needs to be reflected in UI). I don't want to expose all the properties of any control only some of them(relevant to end user); apart from this there are some properties which will be common for all controls e.g. Title, Value(Value will be bound to some property of a control, say Text of TextBox and Content of Label) etc. I am thinking of putting all the common proeprties at one place. Things I am confused aout - How to create such base class, whether to use UserControl or Custom Control for this? How will the binding work between Control, base class proeprties and PropertyGrid? What type of object will I expose to property grid? Any idea on what approch should be followed in this case, any kind of input will really be helpful.

  • Locating binding errors

    - by softengine
    I'm dealing with a large WPF application that is outputting a large number of binding errors. A typical error looks like this: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.ItemsControl', AncestorLevel='1''. BindingExpression:Path=HorizontalContentAlignment; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'HorizontalContentAlignment' (type 'HorizontalAlignment') Problem is I don't know where in the app this is coming from. Searching the entire solution for AncestorType={x:Type ItemsControl} doesn't necessary help since I still don't know which result is the culprit. I've tried setting PresentationTraceSources.DataBindingSource.Switch.Level = SourceLevels.All; but the extra information doesn't help locate the problematic bindings. File names and line numbers is really what I need. Is there anyway to get this information?

  • Cleanup for control inside a FlowDocument

    - by Thorarin
    I have a custom control that I use inside a FlowDocument. The control uses a System.Drawing.ImageAnimator to display transparent, animated GIF images. Why is this such a pain in the butt in WPF anyway? :P In my original implementation, this was causing memory leaks when a paragraph containing the control was being deleted from the document, because the ImageAnimator kept a reference to the control for event handling. I've now implemented a WeakEventManager pattern which seems to indeed fix the leak itself, but I would like to stop "OnFrameChanged" events from being fired if a particular animated GIF is not currently in the document, instead of relying on the garbage collector to eventually collect the control objects and my event manager to notice that there no longer are valid listeners to the event. Basically, I would like to take a more active role in this and have the control react to being removed from the FlowDocument. Is there some way to do this? I've been unable to find it. OnVisualParentChanged doesn't get fired, because the direct parent (a Paragraph) is unchanged.

  • MVVM User Control Issue

    - by Burt
    I have a problem with commands in an MVVM application (I am only learning MVVM so go easy). MyClassViewModel is set to the datacontext for MainForm1, MyList is bound to UserControl1 datacontext and each item in the list is represented by UserControl2. I am trying to fire MyCommand in UserControl2 using the following: <CheckBox IsChecked="{Binding MyBool}" Command="{Binding Path=MyCommand}" CommandParameter="{Binding}"> I get the following error in the output: System.Windows.Data Error: 39 : BindingExpression path error: 'MyCommand' property not found on 'object' ''MyObject'' From this error I know that WPF is looking for the command in the object bound to the UserControl2 what I really need is for it to look for the command in the MainForm1 datacontext (MyClassViewModel). Is it possible to bubble up commands like this and if so how is it done? Is bubbling up the command a good solution?

  • How to get the row and column of button clicked, in the grid event handler?

    - by younevertell
    Once the added button in grid is clicked, how to find which row and column the button is located in the grid event handler, like click event or some other events? Not the button click event handler #region Grid event handler setup myGrid.MouseEnter += new MouseEventHandler(myGrid_MouseEnter); myGrid.MouseLeave += new MouseEventHandler(myGrid_MouseLeave); myGrid.MouseDown += new MouseButtonEventHandler(myGrid_MouseDown); myGrid.MouseUp += new MouseButtonEventHandler(myGrid_MouseUp); #endregion Thanks I notice that Boyan has some solution for the button click event handler case http://stackoverflow.com/questions/363100/in-wpf-how-can-i-determine-what-column-row-in-a-grid-a-control-is In the Click event handler for the button you say: int row; Button btn = sender as Button; if (btn != null) { row = Grid.GetRow(btn); // And you have the row number... } else { // A nasty error occurred... }

  • CommandManager Executed Events don't fire for custom ICommands

    - by Andre Luus
    The WPF CommandManager allows you to do the following (pseudo-ish-code): <Button Name="SomeButton" Command="{Binding Path=ViewModelCommand}"/> And in the code-behind: private void InitCommandEvents() { CommandManager.AddExecutedEventHandler(this.SomeButton, SomeEventHandler); } The SomeEventHandler never gets called. To me this didn't seem like something very wrong to try and do, but if you consider what happens inside CommandManager.AddExecutedEventHandler, it makes sense why it doesn't. Add to that the fact that the documentation clearly states that the CommandManager only works with RoutedCommands. Nonetheless, this had me very frustrated for a while and led me to this question: What would you suggest is the best workaround for the fact that the CommandManager does not support custom ICommands? Especially if you want to add behavior around the execution of a command? For now, I fire the command manually in code behind from the button click event.

  • change color of red box on tri-state checkbox

    - by Adam S
    Hi all. I'm trying to get the green box that appears on the second click of a tri-state checkbox to be red, and also to fill up the box. I found an article here that demonstrates a little bit about using templates to do this: http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/98cf8a65-f4ca-4ff5-9851-c2989b91a013 However, I can't figure out how to interpret all that. I only understand a few of the things in that template and don't know how to get my red box. Can anyone help, and also tell me how you knew what to do?

  • databinding to self without code

    - by jcollum
    I'm building a UserControl in WPF. The control has two properties, Title and Description, that I'd like to bind to two textblocks. Seems real straightforward, and I got it working, but I'm curious about something. To get it to work I had to add this code: void CommandBlock_Loaded(object sender, RoutedEventArgs e) { this.DataContext = this; } My bindings look like this: <TextBlock Text="{Binding Title}" Width="100" ... /> <TextBlock Text="{Binding Description}" Width="100" ... /> What I'm wondering is how come I couldn't get it to work without the this.DataContext = this; and instead use DataContext="{Binding RelativeSource={RelativeSource Self}}" (in the UserControl element of the markup)? I'm sure I'm missing something about DataContexts but don't know what.

  • WPF DataGrid does not scoll on drag

    - by Greg R
    I have a strange problem with a WPF DataGrid from WPF Toolkit. The scrollbars appear correctly when the number of rows grows, and the scrolling works when you press up or down arrows on the scrollbar. The problem comes in when I try to drag the scrollbar on the datagrid. My page has a scroll viewer around it. When I click and drag the scrollbar on the grid, it scrolls the page scroller instead. If the scrollbar does not apear on the page, there grid still does not scroll. Is there a workaround for this??? Would really appreciate some help with this issue! For example, in this case if the page is < 280, it scrolls on drag. But drag scrolling does not work on the grid. <ScrollViewer ScrollViewer.IsDeferredScrollingEnabled="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" > <DockPanel> <dg:DataGrid HorizontalScrollBarVisibility="Auto" SelectionMode="Single" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeColumns="False" CanUserSortColumns="False" AutoGenerateColumns="False" RowHeaderWidth="17" ItemsSource="{Binding Path=OrderSearchVm}" IsReadOnly="True" MaxHeight="280" DockPanel.Dock="Top"> <dg:DataGrid.Columns> <dg:DataGridTextColumn Width="75" Header="Date" Binding="{Binding Path=OrderDate}" > <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Type" Binding="{Binding Path=OrderType}" Width="45"/> <dg:DataGridTextColumn Header="Shipping Name" Binding="{Binding Path=ShipToName}" Width="115"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Shipping Address " Binding="{Binding Path=ShipToAddress}" Width="160"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="E-Mail" Binding="{Binding Path=Email}" Width="140"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> </dg:DataGrid.Columns> </dg:DataGrid> </DockPanel> </ScrollViewer>
