• WPF: Binding to commands in code behind

  - by sofri

  Hi, I have an WPF Microsoft Surface Applikation and I'm using MVVM-Pattern. I have some buttons that are created in code behind. And I would like to bind commands to them but I only know how that works in the XAML like this: <Custom:SurfaceButton Command="{Binding SaveReservationCommandBinding, Mode=OneWay}"/> But I cannot do it like this because my buttons do not exist in the XAML, only in the code behind. So how would a command binding like that works in code behind?

• Binding a slider value on the height of its thumb in WPF

  - by sofri

  Hi, I have a databinding problem in WPF. I would like to "customise" a slider in a way that the thumb grows when you move the slider to the right and the thumb shrinks when you move the slider to the left. So I edited the template for the slider and changed the look of the slider so the slider looks like I want it to. But now I have to bind the height of the thumb to the value of the slider but I do not know how that works. I did some simple data binding things but I cannot figure out how I can bind this "thumb height" that's inside of my slider's template to the slider's value that's inside the User Control where my slider is in. So how can I do it?

• WPF Storyboard works well, except for the first time it runs. Why?

  - by sofri

  Hi, I'm doing a Surface Application. And there I have something like a bulletin board where little cards with news on it are pinned on. On click they shall fly out of the board and scale bigger. My storyboard works well, except for the first time it runs. It's not a smooth animation then but it scales to its final size immediately and it's the same with the orientation-property. Just the center-property seems to behave correctly. This is an example for one of my Storyboards doing that: Storyboard stb = new Storyboard(); PointAnimation moveCenter = new PointAnimation(); DoubleAnimationUsingKeyFrames changeWidth = new DoubleAnimationUsingKeyFrames(); DoubleAnimationUsingKeyFrames changeHeight = new DoubleAnimationUsingKeyFrames(); DoubleAnimationUsingKeyFrames changeOrientation = new DoubleAnimationUsingKeyFrames(); moveCenter.From = News1.ActualCenter; moveCenter.To = new Point(250, 400); moveCenter.Duration = new Duration(TimeSpan.FromSeconds(1.0)); moveCenter.FillBehavior = FillBehavior.Stop; stb.Children.Add(moveCenter); Storyboard.SetTarget(moveCenter, News1); Storyboard.SetTargetProperty(moveCenter, new PropertyPath(ScatterViewItem.CenterProperty)); changeWidth.Duration = TimeSpan.FromSeconds(1); changeWidth.KeyFrames.Add(new EasingDoubleKeyFrame(266, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeWidth.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeWidth); Storyboard.SetTarget(changeWidth, News1); Storyboard.SetTargetProperty(changeWidth, new PropertyPath(FrameworkElement.WidthProperty)); changeHeight.Duration = TimeSpan.FromSeconds(1); changeHeight.KeyFrames.Add(new EasingDoubleKeyFrame(400, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeHeight.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeHeight); Storyboard.SetTarget(changeHeight, News1); Storyboard.SetTargetProperty(changeHeight, new PropertyPath(FrameworkElement.HeightProperty)); changeOrientation.Duration = TimeSpan.FromSeconds(1); changeOrientation.KeyFrames.Add(new EasingDoubleKeyFrame(0, KeyTime.FromTimeSpan(new System.TimeSpan(0, 0, 1)))); changeOrientation.FillBehavior = FillBehavior.Stop; stb.Children.Add(changeOrientation); Storyboard.SetTarget(changeOrientation, News1); Storyboard.SetTargetProperty(changeOrientation, new PropertyPath(ScatterViewItem.OrientationProperty)); stb.Begin(this); News1.Center = new Point(250, 400); News1.Orientation = 0; News1.Width = 266; News1.Height = 400; Pin1.Visibility = Visibility.Collapsed; news1IsOutside = true; Scroll1.IsEnabled = true; What's wrong with it?

• How can I use a config-file in Expression Blend 4?

  - by sofri

  Hi, while trying to use the "InfoStrat"-Bing-Maps-Control in Expression Blend 4 for my Surface Application, I get the error message: "Mixed mode assembly is built against version v2.0.50527 of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information" I already found out that I need to write this configfile: <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0"/> </startup> </configuration> But Expression Blend doesn't seem to recognize that it is there. So how can I solve this problem?

• WPF: Calling a method from a different "branch" of the tree

  - by sofri

  Hey, I'm doing a WPF Application. The tree looks like this: SurfaceWindow --- Startscreen ..........................-------- Page---------- Subpage I'm trying to call a method from the "Subpage" from the "Code Behind" of the Startscreen(Startscreen.xaml.cs). The method from the Subpage looks like this: public void showTheme(ThemeViewModel theme) { ... } If know that I can call it when I'm on the "Page" or the "SurfaceWindow", because it's in the same "branch" of the tree, and I just do something like this: ThemeViewModel theme = (ThemeViewModel)mvm.CurrentItem.ThemeViewModel; katalog.katalogblatt.showTheme(theme); But how do I do it when I'm not on the same branch of the tree and want to call the method?

• WPF: Reset the positions of scatterviewitems?

  - by sofri

  Hi, I have a scatterview with some items in it which I place with Orientation und Center. Now I want to have the possibility to reset the positions of the scatterviewitems after scaling, rotating and moving them, while the program is running. At the moment I do it this way: private void Reset_ContactTapGesture(object sender, Microsoft.Surface.Presentation.ContactEventArgs e) { item1.Center = new Point(150,150); item1.Orientation = 15; item1.Width = 100; item1.Height = 150; } Is there a better way to do it?

• Microsoft Surface: "Read" the tag value of an IdentityTag

  - by sofri

  Hi, is it possible to read the value of an IdentityTag if you place it on the TagVisualizer, without having initalized it before? I would like to use the tags for registering a new object on the Surface but having all the "free" IdentityTags in a Collection for initalizing them all... There must be a better way to do in I think. But the TagVisualizer doesn't seem to do anything when you put a tag on it that it doesn't know.
