start animation that begins with current value (handoff)

Posted By:      Posted Date: September 27, 2010    Points: 0   Category :WPF

I have a WPF Datatemplate that contains a some DataTriggers that start animating the color of a visual. How can I start the animation beginning with the actual value the color propery currently has? Since there might be another animation currently acitve I can not start a new one but when I remove the animation using DataTriggers ExitAction and RemoveStoryboard the position property is set back to its default value. Instead I would like handoff one to the other.

Is this a limitation of WPF that simply can not be done?

<DataTrigger Binding="{Binding Path=State}" Value="Active">
        <BeginStoryboard x:Name="activeStoryboard" HandoffBehavior="SnapshotAndReplace">
                <ColorAnimation To="Green" FillBehavior="HoldEnd" Duration="00:00:0.25" 
                                Storyboard.TargetProperty="Color" />
        <RemoveStoryboard BeginStoryboardName="activeStoryboard" />

Trying to start second animation from completion point of first animation, but, properties are reset


Trying to use two arcsegment-based geometries to move an image along a semi-ellipse in, well, two segments.

So, the image at 270 degrees for example, upon event, will translate clockwise to 180 degrees. Finish, stay there. Then another event will have it translate (continue) clockwise to 90 degrees.

I have all the arcsegments, path figures, path geometry, storyboard stuff working. In fact the second translation works correctley, i.e. correct rotation angle and "relative" path.

However, it seems that the myStoryboard.Begin(this,true); statement first sends the image element back to the first (original) starting point, but, then translates correctly but relative to that first starting point ... not where the first segment ends.

Using the image's RenderTransform property's X and Y to translate.

Like I said all that is working, but, the second time doesn't start from the end of the first, even though the image stays there. On call the image moves back to the original starting point, then does what it should, essentially ending at 0 degrees, not 90, since it does the second segment from 270, not 180.

I've tried all kinds of stuff for days (feeling a bit inept frankly :( Learned that animations hold properties at bay, so I've tried Remove, FillBehavior.Stop, and manually setting the new starting point. I've looked for GetC

Silverlight Simple Animation

Silverlight has several built in techniques for animating controls. Many of these technologies are particularly useful for creating simple animations meant to decorate a web page with eye catching movement that draws the reader's attention. In this post I will skip over these decorative technologies, and instead show how to create a simple animation using a technique similar to those used in many games.

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

Animation Extender ( LinkButton Disbale )


My flyout animation starts on a click of linkbutton, everything works fine on IE, as I click the linkbutton flyout animation is triggered and linkbutton gets disbaled during the animation. But on Firefox and Chorme linkbutton doesn't get disbaled , due which if I again and again click on the linkbutton the flyout animation keeps moving towards left side on every click.

In firefox and chorme linkbutton always remains enabled.

Users getting logged out because HttpContext.Current is null


We've  been trying to fix this one for a couple years, and I'm just out of ideas, so any help is really appreciated!

We've got a fairly large, complex web application that uses Forms Authentication to authenticate users.  Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies.  In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. 

Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage session

As for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was.  This seems to work well for us.  It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.

What's happening is that certain users are being logged out after just a few minutes.  We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out.  We do not know why the HttpContext.Current is null, and I underst

Registering controls of current assembly object reference NOT set error


Hi There,

I have created a simple ASP.net Web Application (2.0) and have added a web user control.

Now in my page I have added this control but I have registered like this,

<%@ Register Assembly="WebApplication1" Namespace="WebApplication1" TagPrefix="Custom" %>

Which means I want to access all the controls in my current Web Application project

Then I have added my user control like this,

<Custom:MyUserControl ID="MyUserControl1" runat="server" PublicProperty="Hello" />

Every thing is fine but when I execute the project, NO control on my user control gets "instantiated" and thus I receive error "Object Reference Not Set"

Note that My Control has,

1) Public property PublicProperty as String

2) 1 Label control

In Load Event Handler I am setting Text property of Label Control to PublicProperty. Here object reference NOT set error occurs (which means Label control is NOT initialized).

I don't want to register my control using Src, TagPrefix etc. Any ideas?

Introducing the issue, Howard Dierking points out that you can't simply parallelize your code blindly if you expect to truly reap the benefits that parallelism promises.

ASP.NET: Jump Start Your Web Site Development with the ASP.NET Starter Kits


If you're building an ASP.NET Web site you could probably use a good, solid code foundation to start with and build upon. Wouldn't it be nice to start with a complete site, make a few tweaks and customizations, and go live? The ASP.NET Starter Kits are packaged solutions that let you do just that. The five kits-Community, Reports, Commerce, Portal, and Time Tracker-supply full, reusable code that can be easily customized. In addition, there are a number of ISPs that support automatic deployment of ASP.NET Starter Kit Web sites, leaving you with little left to do when you have to get there fast. Here, the author introduces the ASP.NET Starter Kits and builds a community Web site with lots of advanced features such as ratings, user polls, upload quotas, change notifications, and themes.

DirectX 8.0: Enhancing Real-Time Character Animation with Matrix Palette Skinning and Vertex Shaders


DirectX 8.0 allows the creation of smooth and realistic character movements that are more life-like than simple articulated structure animations. This is made possible by its improved support for vertex tweening and blended vertex deformations, also known as soft-skinning. After a brief history of the use of these techniques in DirectX, soft-skinning using the fixed function pipeline is discussed. This is followed by the use of matrix palettes from within vertex shaders to create a customized soft-skinning solution that takes advantage of the benefits of vertex shaders, such as hardware acceleration and custom lighting algorithms without the limitations of fixed-function solutions.
