  • Access Controls in Silverlight DataGrid Column Header from Code

    - by fuzzyman
    We have custom headers in the Silverlight DataGrid using the ContentTemplate. We've got a button in the header and need to programmatically access the button to hook up the event. We're using IronPython, so we can't statically bind the event in the xaml (plus we use the grid for many different views - so we dynamically generate the xaml). How can we get access to controls inside a datagrid column header?

  • How to detect the vertical scrollbar in a DataGridView control

    - by Billy
    Using winforms in vs2008. I have a DataGridView and I would like to detect when the vertical scroll bar is visible. What event should I register for? I am adding the summing the each cell value in the last column of the grid and displaying that value in a textbox at the bottom of the DataGridView. I would like this textbox to stay lined up with the cell values (I have made them right aligned since it is $$ values) even after the scroll bar is present.

  • M-V-VM, isn't the Model leaking into the View?

    - by BFree
    The point of M-V-VM as we all know is about speraration of concerns. In patterns like MVVM, MVC or MVP, the main purpose is to decouple the View from the Data thereby building more flexible components. I'll demonstrate first a very common scenario found in many WPF apps, and then I'll make my point: Say we have some StockQuote application that streams a bunch of quotes and displays them on screen. Typically, you'd have this: StockQuote.cs : (Model) public class StockQuote { public string Symbol { get; set; } public double Price { get; set; } } StockQuoteViewModel.cs : (ViewModel) public class StockQuoteViewModel { private ObservableCollection<StockQuote> _quotes = new ObservableCollection<StockQuote>(); public ObservableCollection<StockQuote> Quotes { get { return _quotes; } } } StockQuoteView.xaml (View) <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300"> <Window.DataContext> <local:StockQuoteViewModel/> </Window.DataContext> <Window.Resources> <DataTemplate x:Key="listBoxDateTemplate"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Symbol}"/> <TextBlock Text="{Binding Price}"/> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox ItemTemplate="{StaticResource listBoxDateTemplate}" ItemsSource="{Binding Quotes}"/> </Grid> </Window> And then you'd have some kind of service that would feed the ObservableCollection with new StockQuotes. My question is this: In this type of scenario, the StockQuote is considered the Model, and we're exposing that to the View through the ViewModel's ObservableCollection. Which basically means, our View has knowledge of the Model. Doesn't that violate the whole paradigm of M-V-VM? Or am I missing something here....?

  • Routed Command Question

    - by Andrew
    I'd like to implement a custom command to capture a Backspace key gesture inside of a textbox, but I don't know how. I wrote a test program in order to understand what's going on, but the behaviour of the program is rather confusing. Basically, I just need to be able to handle the Backspace key gesture via wpf commands while keyboard focus is in the textbox, and without disrupting the normal behaviour of the Backspace key within the textbox. Here's the xaml for the main window and the corresponding code-behind, too (note that I created a second command for the Enter key, just to compare its behaviour to that of the Backspace key): <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <TextBox Margin="44,54,44,128" Name="textBox1" /> </Grid> </Window> And here's the corresponding code-behind: using System.Windows; using System.Windows.Input; namespace WpfApplication1 { /// <summary> /// Interaction logic for EntryListView.xaml /// </summary> public partial class Window1 : Window { public static RoutedCommand EnterCommand = new RoutedCommand(); public static RoutedCommand BackspaceCommand = new RoutedCommand(); public Window1() { InitializeComponent(); CommandBinding cb1 = new CommandBinding(EnterCommand, EnterExecuted, EnterCanExecute); CommandBinding cb2 = new CommandBinding(BackspaceCommand, BackspaceExecuted, BackspaceCanExecute); this.CommandBindings.Add(cb1); this.CommandBindings.Add(cb2); KeyGesture kg1 = new KeyGesture(Key.Enter); KeyGesture kg2 = new KeyGesture(Key.Back); InputBinding ib1 = new InputBinding(EnterCommand, kg1); InputBinding ib2 = new InputBinding(BackspaceCommand, kg2); this.InputBindings.Add(ib1); this.InputBindings.Add(ib2); } #region Command Handlers private void EnterCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside EnterCanExecute Method."); e.CanExecute = true; } private void EnterExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside EnterExecuted Method."); e.Handled = true; } private void BackspaceCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside BackspaceCanExecute Method."); e.Handled = true; } private void BackspaceExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside BackspaceExecuted Method."); e.Handled = true; } #endregion Command Handlers } } Any help would be very much appreciated. Thanks! Andrew

  • Command line or library "compare tables" utility for SQL server with comprehensive diff output to a

    - by MicMit
    I can't find anything like that. Commercial or free ( XSQL Lite is suitable for my case and ) tools show diffs in grids with possibility to export to CSV. Also they generate sync SQL scripts when run from command line. What I need is an output as a comprehensive report ( XML , HTML ) suitable for parsing so that I would be able to show similar diff grid in my application ( updated old/new values for each column , added - all values for row , deleted - all values for row and etc... ) .

  • WPF, how can I optimize lines and circles drawing ?

    - by Aurélien Ribon
    Hello ! I am developping an application where I need to draw a graph on the screen. For this purpose, I use a Canvas and I put Controls on it. An example of such a draw as shown in the app can be found here : http://free0.hiboox.com/images/1610/d82e0b7cc3521071ede601d3542c7bc5.png It works fine for simple graphs, but I also want to be able to draw very large graphs (hundreds of nodes). And when I try to draw a very large graph, it takes a LOT of time to render. My problem is that the code is not optimized at all, I just wanted it to work. Until now, I have a Canvas on the one hand, and multiple Controls on the other hands. Actually, circles and lines are listed in collections, and for each item of these collections, I use a ControlTemplate, defining a red circle, a black circle, a line, etc. Here is an example, the definition of a graph circle : <!-- STYLE : DISPLAY DATA NODE --> <Style TargetType="{x:Type flow.elements:DisplayNode}"> <Setter Property="Canvas.Left" Value="{Binding X, RelativeSource={RelativeSource Self}}" /> <Setter Property="Canvas.Top" Value="{Binding Y, RelativeSource={RelativeSource Self}}" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type flow.elements:DisplayNode}"> <!--TEMPLATE--> <Grid x:Name="grid" Margin="-30,-30,0,0"> <Ellipse x:Name="selectionEllipse" StrokeThickness="0" Width="60" Height="60" Opacity="0" IsHitTestVisible="False"> <Ellipse.Fill> <RadialGradientBrush> <GradientStop Color="Black" Offset="0.398" /> <GradientStop Offset="1" /> </RadialGradientBrush> </Ellipse.Fill> </Ellipse> <Ellipse Stroke="Black" Width="30" Height="30" x:Name="ellipse"> <Ellipse.Fill> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="0" Color="White" /> <GradientStop Offset="1.5" Color="LightGray" /> </LinearGradientBrush> </Ellipse.Fill> </Ellipse> <TextBlock x:Name="tblock" Text="{Binding NodeName, RelativeSource={RelativeSource Mode=TemplatedParent}}" Foreground="Black" VerticalAlignment="Center" HorizontalAlignment="Center" FontSize="10.667" /> </Grid> <!--TRIGGERS--> <ControlTemplate.Triggers> <!--DATAINPUT--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="NODETYPE" /> <Condition Property="NodeType" Value="DATAINPUT" /> </MultiTrigger.Conditions> <Setter TargetName="tblock" Property="Foreground" Value="White" /> <Setter TargetName="ellipse" Property="Fill"> <Setter.Value> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="-0.5" Color="White" /> <GradientStop Offset="1" Color="Black" /> </LinearGradientBrush> </Setter.Value> </Setter> </MultiTrigger> <!--DATAOUTPUT--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="NODETYPE" /> <Condition Property="NodeType" Value="DATAOUTPUT" /> </MultiTrigger.Conditions> <Setter TargetName="tblock" Property="Foreground" Value="White" /> <Setter TargetName="ellipse" Property="Fill"> <Setter.Value> <LinearGradientBrush EndPoint="0,1"> <GradientStop Offset="-0.5" Color="White" /> <GradientStop Offset="1" Color="Black" /> </LinearGradientBrush> </Setter.Value> </Setter> </MultiTrigger> ....... THERE IS A TOTAL OF 7 MULTITRIGGERS ....... </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> Also, the lines are drawn using the Line Control. <!-- STYLE : DISPLAY LINK --> <Style TargetType="{x:Type flow.elements:DisplayLink}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type flow.elements:DisplayLink}"> <!--TEMPLATE--> <Line X1="{Binding X1, RelativeSource={RelativeSource TemplatedParent}}" X2="{Binding X2, RelativeSource={RelativeSource TemplatedParent}}" Y1="{Binding Y1, RelativeSource={RelativeSource TemplatedParent}}" Y2="{Binding Y2, RelativeSource={RelativeSource TemplatedParent}}" Stroke="Gray" StrokeThickness="2" x:Name="line" /> <!--TRIGGERS--> <ControlTemplate.Triggers> <!--BRANCH : ASSERTION--> <MultiTrigger> <MultiTrigger.Conditions> <Condition Property="SkinMode" Value="BRANCHTYPE" /> <Condition Property="BranchType" Value="ASSERTION" /> </MultiTrigger.Conditions> <Setter TargetName="line" Property="Stroke" Value="#E0E0E0" /> </MultiTrigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> So, I need your advices. How can I drastically improve the rendering performances ? Should I define each MultiTrigger circle rendering possibility in its own ControlTemplate instead ? Is there a better line drawing technique ? Should I open a DrawingContext and draw everything in one control, instead of having hundreds of controls ?

    I'm using the new API to set the width of my jqGrid like this: $('#grid').jqGrid('setGridWidth', $(window).width() * 0.98); The problem is that in IE7 I'm getting this error: 'p.cellLayout' is null or not an object This only happens in IE7 (IE8, Firefox and Chrome work fine). Has anybody else encounter this problem and fixed it?

  • Measurement conversion on the fly

    - by ikadewi
    Hi All I'd like to ask re: measurement conversion on the fly, here's the detail : Requirement: To display unit measurement with consider setting. Concerns: - Only basic (neutral) unit measurement is going to be stored in database, and it is decided one time. The grid control has direct binding to our business object therefore it has complexity to do conversion value. Problem: How to display different unit measurement (follow a setting), consider that controls are bind to business object? Your kind assistance will be appreciated. Thank you ikadewi

  • Blurry text in WPF even with ClearTypeHinting enabled?

    - by rFactor
    I have a grid with this template and styles in WPF/XAML: <Setter Property="TextOptions.TextFormattingMode" Value="Display" /> <Setter Property="RenderOptions.ClearTypeHint" Value="Enabled" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridCell}"> <Border Padding="{TemplateBinding Padding}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True"> <ContentPresenter x:Name="CellContent" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RenderOptions.ClearTypeHint="Enabled" /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="CellContent" Property="TextOptions.TextFormattingMode" Value="Display" /> <Setter TargetName="CellContent" Property="RenderOptions.ClearTypeHint" Value="Enabled" /> <Setter TargetName="CellContent" Property="Effect"> <Setter.Value> <DropShadowEffect ShadowDepth="2" BlurRadius="2" Color="Black" RenderingBias="Quality" /> </Setter.Value> </Setter> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> The DropShadowEffect I have when you select a grid row, seems to make the text rendering blurry (gray anti-aliasing): When I remove the drop shadow effect, it looks clear because it now uses ClearType and not gray sub-pixel anti-aliasing: I have tried applying RenderOptions.ClearTypeHint="Enabled" to the ContentPresenter as seen above, but it does not help. How do I force WPF to render the text that gets displayed with drop shadow effect to retain Cleartype anti-aliasing, instead of that ugly blurry gray sub-pixel anti-aliasing? Some believe it's blurry because of the drop shadow -- this is not true. It's blurry only because ClearType is not used. This is how it looks like in Firefox when shadow AND ClearType: ClearType enabled text is colorful -- but that blurry text is not, because it does not use ClearType -- it uses gray sub-pixel anti-aliasing and that's not how ClearType works: http://en.wikipedia.org/wiki/ClearType The question is: how do I enable ClearType for this text?

  • isPostBack as Query Parameter

    - by Steven
    I created an ASPX page with search controls to the left bound as controls for an AccessDataSource. I want the data grid to be blank on the first calling of the page, but show the results for subsequent page loads. I plan to achieve this by putting [pFirstRun] = False as my first WHERE condition with the parameter pFirstRun tied to the value isPostBack. How do I achieve this? Alternatively, is there a better way to achieve this goal?

  • I've got my 2D/3D conversion working perfectly, how to do perspective

    - by user346992
    Although the context of this question is about making a 2d/3d game, the problem i have boils down to some math. Although its a 2.5D world, lets pretend its just 2d for this question. // xa: x-accent, the x coordinate of the projection // mapP: a coordinate on a map which need to be projected // _Dist_ values are constants for the projection, choosing them correctly will result in i.e. an isometric projection xa = mapP.x * xDistX + mapP.y * xDistY; ya = mapP.x * yDistX + mapP.y * yDistY; xDistX and yDistX determine the angle of the x-axis, and xDistY and yDistY determine the angle of the y-axis on the projection (and also the size of the grid, but lets assume this is 1-pixel for simplicity). x-axis-angle = atan(yDistX/xDistX) y-axis-angle = atan(yDistY/yDistY) a "normal" coordinate system like this --------------- x | | | | | y has values like this: xDistX = 1; yDistX = 0; xDistY = 0; YDistY = 1; So every step in x direction will result on the projection to 1 pixel to the right end 0 pixels down. Every step in the y direction of the projection will result in 0 steps to the right and 1 pixel down. When choosing the correct xDistX, yDistX, xDistY, yDistY, you can project any trimetric or dimetric system (which is why i chose this). So far so good, when this is drawn everything turns out okay. If "my system" and mindset are clear, lets move on to perspective. I wanted to add some perspective to this grid so i added some extra's like this: camera = new MapPoint(60, 60); dx = mapP.x - camera.x; // delta x dy = mapP.y - camera.y; // delta y dist = Math.sqrt(dx * dx + dy * dy); // dist is the distance to the camera, Pythagoras etc.. all objects must be in front of the camera fac = 1 - dist / 100; // this formula determines the amount of perspective xa = fac * (mapP.x * xDistX + mapP.y * xDistY) ; ya = fac * (mapP.x * yDistX + mapP.y * yDistY ); Now the real hard part... what if you got a (xa,ya) point on the projection and want to calculate the original point (x,y). For the first case (without perspective) i did find the inverse function, but how can this be done for the formula with the perspective. May math skills are not quite up to the challenge to solve this. ( I vaguely remember from a long time ago mathematica could create inverse function for some special cases... could it solve this problem? Could someone maybe try?)

  • Simulating graphing paper on iPhone

    - by Rick
    I need to implement 'graphing paper' in an iPhone app. The user should be presented with a grid. They user can touch individual squares to turn them on, or if they're already on, off.The user can pinch to zoom and scroll around the paper as well.. So far I'm thinking Quartz 2D + UIScrollView is the way to do this but these are both areas of iPhone development that I'm unfamiliar with. Does this seem like a reasonable strategy?
