• ASP.NET MVC2 and AJAX

  - by Jason

  I am currently developing a new website utilizing ASP.NET MVC2. Much of what I want to do with the website (from a front-end standpoint) involves AJAX-y-type tasks. Two examples: I want to display forms, and switch between them via a drop-down menu (or through links) without having to go back and hit the server every single time. I want the user to be able to select points on a Chart Control and have portions of the page refresh with the appropriate data depending on what he/she selects (partial page refresh). In both these cases, I am able to accomplish what I wish to accomplish using the traditional web forms event handlers, etc. Unfortunately, the use of a ScriptManager violates the spirit of MVC. It seems as if MVC prevents the use of many of the controls that are available to ASP.NET. So, my question is: how do I use AJAX and make AJAX calls without utilizing ScriptManager and the web forms method of utilizing event handlers?

• How do I add additional data to a DataGridRowGroupHeader?

  - by Jeff Yates

  I have a DataGrid that is showing some data via a PagedCollectionView with one group definition. I have created a Style for the corresponding DataGridRowGroupHeader under which I have added a ControlTemplate containing an additional TextBlock and a spacing Rectangle. I would like to bind the widths of these controls to the widths of particular columns, but I am struggling to get this working. I would also like to bind the Text property of the TextBlock to a value. I tried binding the widths via the Width property of a Rectangle in resources but this didn't work (possibly because the Rectangle was never drawn and therefore didn't calculate it's layout). However, I believe both sets of bindings can be performed with some use of one or more ValueConverter implementations, but I was wondering if there was a better way. Can any of this be achieved through the definition of a ControlTemplate?

• Infragistics WebDateChooser when added from .cs file gave error

• WPF: RenderOptions.EdgeMode="Unspecified" vs "Alias" override global setting with local setting

  - by msfanboy

  Hello, in the ressource-tag of my MainWindowView.xaml I have this markup: RenderOptions.EdgeMode="Aliased" to get a general sharp look of my whole application. Using mostly rectangular shapes/controls this works fine. But for my validation error symbols I use a red ellipse with a white cross or "X" in it. The ellipse is using now the global "Aliased" settings what looks not good because I can see the pixelated border of the ellipse. Using now does NOT change anything ??? I always set in wpf local settings override global settings ?

• WPF drop shadow

  - by Petezah

  Currently I'm making something in WPF that has a border that contains a grid and other controls. The problem I'm facing is that whenever I set the Border.Effect property to a drop shadow effect every control contained in the border now has a drop shadow. Is there a way to set the shadow just to the border and not every control contained in the border? Here is a short example of my code: <Grid> <Border Margin="68,67,60,67" BorderBrush="Black" BorderThickness="1" CornerRadius="10"> <Border.Effect> <DropShadowEffect/> </Border.Effect> <Rectangle Fill="White" Stroke="Black" Margin="37,89,118,98" /> </Border> </Grid>

• How to use JQuery UI datepicker with bgIframe on IE 6

  - by Steve Davies

  I am trying to use the JQuery UI datepicker (latest stable version 1.5.2) on an IE6 website. But I am having the usual problems with combo boxes (selects) on IE6 where they float above other controls. I have tried adding the bgIframe plugin after declaring the datepicker with no luck. My guess is that the .ui-datepicker-div to which I am attaching the bgIframe doesn't exist until the calendar is shown. I am wondering if I can put the .bgIframe() command directly into the datepicker .js file and if so, where? (the similar control by kelvin Luck uses this approach) Current code $(".DateItem").datepicker({ showOn:"button", ... etc ... }); $(".ui-datepicker-div").bgIframe();

• Outlook 2003 View Control with C#

  - by Eleasar

  I want to embed a custom c# windows form (or WPF) user control into an outlook view. I am using Outlook 2003 and Visual Studio 2008. I did download an example for Outlook 2007 here: http://blogs.msdn.com/e2eblog/archive/2008/01/09/outlook-folder-homepage-hosting-wpf-activex-and-windows-forms-controls.aspx and also here: http://msdn.microsoft.com/en-us/library/aa479345.aspx I tested it and under 2007 it is working, but for 2003 i am getting the following error when i want to open the view: Could not complete the operation due to error 80131509 I can start it from Visual Studio, it is registering the folder just fine, debugging works and all that. It creates an HTML page that contains my type as an object parameter - but the Initialize method that should be called is either not present (not shown via JS) or it has some errors. The breakpoints for RegisterSafeForScripting are also never hit - maybe related to that. Thx in advance!

• Initiating UserControl via MVVM in WPF / focus issue.

  - by benndev

  Hi there I have a few usercontrols loaded into a tabcontrol via MVVM in WPF. Within the XAML for the usercontrol I am setting focus to a textbox using the FocusManager, however this appears to only work when the first instance of the usercontrol is created. Just to test I added a loaded event handler to the usercontrol - this is only called on the first instance. I'm using data templates for the user controls as follows: <DataTemplate DataType="{x:Type local:UserTypeViewModel}"> <local:UserTypeView /> </DataTemplate> The textbox is focused as follows: FocusManager.FocusedElement="{Binding ElementName=txtName}" Additionally I'm using a global event handler (for the textbox GotFocus event) which selects all the text using a dispatcher. If anyone has any tips on how to achieve focus with every usercontrol I'd be very grateful. Thanks, Ben.

• Recommendation for high performance WPF Chart

  - by Ajaxx

  We're working on a WPF-based desktop application that charts financial markets information (candlestick charts, overlayed indicator curves, volume, etc). The charts are displayed in real-time with responses to market ticks being shown in real-time (updating one to two times per second is probably a reasonable display refresh policy). We've been looking for a software package (commercial is fine by us) that has the capability of displaying these charts. Additionally, we'd like to have an approach that can render the initial amount of data in a reasonable timeframe (give or take 100-200ms from the time we hand the data over to a complete render on screen). Also we view multiple charts (5-10) simultaneously so a solution that chews up 50% of my CPU to display one chart really isn't going to work well. Has anyone had any good experiences with charting controls. We've had to hand roll the last few charts we've done and I'd prefer not to do it again. Solutions that can make use of the GPU to minimize CPU utilization would be nice as well.

• How can I resolve exception: Error executing child request for ChartImg.axd

  - by macleojw

  I'm using the Chart Controls for Mircosoft .NET Framerwork. Most of the time they work perfectly. However, if I leave a page for longer than 20-30 mins and then try to refresh the page, I get an error saying: Error executing child request for ChartImg.axd. Exception Details: System.Web.HttpException: Error executing child request for ChartImg.axd. If I update the page using an AJAX update panel I get the following error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd It seems that the chart handler stops after a period of inactivity. Most of the webpages I've looked at for this error are for situations when this error is displayed all the time. In my case it is only displayed after a period of inactivity. Can someone provide a better explanation of what is happening and suggest a solution?

• iPad: Merge concept of SplitViewController and NavigationController in RootView?

  - by MikeN

  I'm having trouble merging the two concepts of using a SplitViewController in my main view and having the "RootView" controller that controls the left panes popup/sidebar table view. I want to have the left "RootView" act as a navigation menu, but how do I do this when the RootView is tied through MainWindow.xib into the left pane of the SplitView? Basically, I want the left navigation to work just like the built-in email applications folder drilldown navigation. Is there an example iPad project out there that uses both SplitView and a NavigationView for the left/Root pane?

• How do I base a style on a Silverlight toolkit theme style

  - by Ian Oakes

  I've being trying to add a theme from the Silverlight toolkit to a project. In the project there are a number of existing styles used in the layout. The problem is when any control has an explict style applied to it does not receive any attributes of the style from the theme. In WPF I would use something like BasedOn={x:Type TextBox}, but this is not supported in Silverlight. I've considered going through the theme and setting a key for every style and then using BasedOn to create both an implicit style to use with the ImplictStyleManager, as well as another explicit style for use with the existing styled controls. Have you got any better ideas?

• Validation on DropDownListFor not working with DataAnnotations

  If I have a drop down list as follows <div class="editor-label"> <%= Html.DropDownListFor(model => model.CardDetail.SelectedCardSchemeId, Model.CardDetail.CardSchemes, "Select")%> </div> and in my model I am using DataAnnotations [Required(ErrorMessage = "* Required SelectedCardSchemeId Message")] public int SelectedCardSchemeId { get; set; } How can I get the message to appear in the view? In debug I can see the ModelState error is populated, but the message is not displayed on the view. I do not have issues with displaying error message for other controls (TextBoxFor)

• WPF Custom Control - ItemsControl template not being applied.

  - by Patrick White

  I'm building a custom WPF control that derives from TabControl. In the ControlTemplate, I'm using a ItemsControl to display a list that is being bound from the template (an observable collection of type FileMenuItem). During program execution, I'm getting the following error in the output window: ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='FileMenuItem' The type FileMenuItem is derived from MenuItem. I googled the error and couldn't find anything about it, has anyone run into this while developing custom controls? I can post more code if it would help. Thanks!

• PowerShell dataGridView - Copy only one Row into an other dataGridView

  - by Marcel L.

  I´ve got a very short question about the "dataGridView". I´m developing with the Microsoft PowerShell and I want to copy one Row (from $dataGridView1) to the other ($dataGridView2). With this Code I can only Copy the Value of the last focused Cell. I´ve tried to make this for a whole Row, but it´s only working with Cells. Here is my Code: **$btnListeAdd.Add_Click({ $Row = $dataGridView1.Rows[ $dataGridView1.CurrentCell.RowIndex ] $dataGridView2.Rows.Add( $dataGridView1.CurrentCell.Value ) $dataGridView1.Rows.Remove( $Row ) }) $tabListe.Controls.Add($btnListeAdd)** Only the market Cell in $dataGridView1 (similar Column 1 or 2) will be cloned in Column1 in $dataGridView2 - in a extra Row, yey. Thanks for helping me. Please show mercy. It´s my first day with the PowerShell. Kind regards, Marcel L.

• Win32: Is there a replacement GDI32.dll that uses hardware acceleration?

  - by Ian Boyd

  Has anyone out there created a version of GDI32.dll that takes advantage of hardware acceleration available on the machine? gdiplus.dll? Starting with Windows Vista, GDI is no longer hardware accelerated. (GDI+ was never hardware accelerated). Without Microsoft fixing GDI (and GDI+) to be able to run well on the computer: native applications (C++ MFC, Delphi, etc), and managed WinForms applications, will continue to run poorly forever. While i could use Direct2D for business applications, i cannot control the fact that the development environment still creates controls, with decades of library support code, that assumes the presence of GDI.

• Coinitialize error on IntraWeb using ADO

  - by Jamo

  Already asked on the Evil Exchange, but as always that was no help. I'm having this problem today: When creating a stand alone web application using IntraWeb, I get this exception in the IDE when I try to test out a session from my app in the browser: First chance exception at $7C812A6B. Exception class EOleSysError with message 'CoInitialize has not been called'. Process WebContactManager.exe (1112) If I click "continue" on the IDE exception dialog, the browser itself just shows: 200 OK ...rather than the controls on my main form. This error does not seem to occur when I replace ADO with other database components such as dbExpress or BDE. What is this error telling me, and how do I fix it? (Note I'm using the stock "VCL for the Web" IntraWeb components which come built-in with D2007). Thanks in advance for any and all help!

• Binding to a WPF hosted control's DependencyProperty in WinForms

  - by Reddog

  I have a WinForms app with some elements that are hosted WPF user controls (using ElementHost). I want to be able to bind my WinForm's control property (Button.Enabled) to a custom DependencyProperty of the hosted WPF user control (SearchResults.IsAccountSelected). Is it possible to bind a System.Windows.Forms.Binding to a property managed by a DependencyProperty? Also, since I know the System.Windows.Forms.Binding watches for INotifyPropertyChanged.PropertyChanged events - will a property backed by a DependencyProperty automatically fire these events or will I have to implement and manage the sending of PropertyChanged events manually?

• NSTableView and NSSearchField in an NSView, which is the outlet of an NSMenuItem, don't work

  - by Koning Baard XIV

  I'm having an NSView, which is set as the view: outlet of an NSMenuItem. The view contains an NSTableView (inside an NSScrollView) and an NSSearchField. The NSMenu is shown when the user clicks a specific NSStatusItem. When I launch the application from Xcode (Build and Run), the controls behave well, but whenever I launch it from the Finder (like the users would), they don't work and don't take any focus. My application is an LSUIElement. Can anyone help me out? Thanks.

I have a app which shows load a flash movie in form, using this code axShockwaveFlash1 = new AxShockwaveFlashObjects.AxShockwaveFlash() axShockwaveFlash1.LoadMovie(0, Form1.currentGame); The problem is that when the Loadmovie method is called to load another flash file, without closing the form , the new flash is 'messed' up. to be more specific , it seems that the background and some controls of the previous flash still remain, 'spoiling' the new flash that is loaded. why? Using the following methods before loading the second flash video makes no difference axShockwaveFlash1.Refresh(); axShockwaveFlash1.Stop(); Solution ?

• Edit TabControl template in Silverlight project

  - by philbrowndotcom

  I'm trying to modify the template for the TabControl in my silverlight application. I used Expression Blend to get the Template and copied it into my project. I did this before for Expander and got it to work with a few minor adjustments. The template for TabControl references the ns/assembly "clr-namespace:System.Windows.Controls.Primitives;assembly=System.Windows.Controls" and uses the TabPanel control from it. I can't seem to make a reference to this. I'm using silverlight 3 and .NET 3 Thanks <UserControl.Resources> <ControlTemplate x:Key="mytemplate" TargetType="sdk:TabControl"> <Grid> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualStateGroup.Transitions> <VisualTransition GeneratedDuration="0"/> </VisualStateGroup.Transitions> <VisualState x:Name="Normal"/> <VisualState x:Name="Disabled"> <Storyboard> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="Opacity" Storyboard.TargetName="DisabledVisualTop"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualBottom"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualLeft"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="DisabledVisualRight"> <SplineDoubleKeyFrame KeyTime="0" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Grid x:Name="TemplateTop" Visibility="Collapsed"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelTop" Margin="2,2,2,-1" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0,0,3,3" MinWidth="10" MinHeight="10" Grid.Row="1"> <ContentPresenter x:Name="ContentTop" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualTop" Background="#8CFFFFFF" CornerRadius="0,0,3,3" IsHitTestVisible="False" Opacity="0" Grid.Row="1" Grid.RowSpan="2" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateBottom" Visibility="Collapsed"> <Grid.RowDefinitions> <RowDefinition Height="*"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelBottom" Margin="2,-1,2,2" Grid.Row="1" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="3,3,0,0" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentBottom" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualBottom" Background="#8CFFFFFF" CornerRadius="3,3,0,0" IsHitTestVisible="False" Opacity="0" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateLeft" Visibility="Collapsed"> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="*"/> </Grid.ColumnDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelLeft" Margin="2,2,-1,2" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Grid.Column="1" CornerRadius="0,3,3,0" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentLeft" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualLeft" Background="#8CFFFFFF" Grid.Column="1" CornerRadius="0,3,3,0" IsHitTestVisible="False" Opacity="0" Canvas.ZIndex="1"/> </Grid> <Grid x:Name="TemplateRight" Visibility="Collapsed"> <Grid.ColumnDefinitions> <ColumnDefinition Width="*"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <System_Windows_Controls_Primitives:TabPanel x:Name="TabPanelRight" Grid.Column="1" Margin="-1,2,2,2" Canvas.ZIndex="1"/> <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="3,0,0,3" MinWidth="10" MinHeight="10"> <ContentPresenter x:Name="ContentRight" Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalAlignment}"/> </Border> <Border x:Name="DisabledVisualRight" Background="#8CFFFFFF" CornerRadius="3,0,0,3" IsHitTestVisible="False" Margin="0" Opacity="0" Canvas.ZIndex="1"/> </Grid> </Grid> </ControlTemplate> </UserControl.Resources>

• WPF TextBox trigger to clear Text

  - by PaN1C_Showt1Me

  Hi ! I have many TextBox controls and I'm trying to write a style that clears the Text property when the Control is disabled. I don't want to have Event Handlers in code behind. I wrote this: <Style TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="IsEnabled" Value="False"> <Setter Property="Text" Value="{x:Null}" /> </Trigger> </Style.Triggers> </Style> The problem is that if the TextBox is defined like: <TextBox Text={Binding Whatever} /> then the trigger does not work (probably because it's bound) How to overcome this problem?

• jQuery UI Autocomplete - style like a standard <SELECT>

  - by jkohlhepp

  I'm on the verge of starting a new web application that is likely to have need for both standard, simple dropdowns as well as more feature-rich autocomplete controls for longer lists of values, better type ahead behavior, etc. I'm planning on using the jQuery UI Autocomplete widget along with some combobox behavior as detailed here: http://jqueryui.com/demos/autocomplete/#combobox My concern is that "out of the box" the Autocomplete widget looks very different than a standard control. Since is not easy to skin/style, I'm hoping to adjust the Autocomplete to look & feel as close to the as possible, except in the cases where the increased functionality justifies a different L&F. What is the best way to go about reskinning the Autocomplete to look more like a ? Has this already been done somewhere? Should I use jQuery UI theming? Other options?
