Yes, it's fixed in RC0

Karen Corby - MSFT:
he VisualStateManager.VisualStateGroups tag does give a compile-time warning in VisualStateManager. This error is a known tools issue, and does not affect actual compilation or runtime behavior. (If you attempt to compile the XAML with the VisualStateManager.VisualStateGroups tag in VS, it will compile successfully and run as expected.)

Not strictly true - I created a new Control Template for a button using blend, and saved it as a Button resource.

The resulting code not only had errors in VS before compiling, but after compiling they resulted in runtime errors. Aside from the VSM issue, the reference :

<Button...>
<Button.Template><StaticResource ResourceKey="myTemplateName" /></Button.Template></Button>

Caused it to crash because the StaticResource wasn't found.

I was able to move all my ControlTemplate code into a style as one of the other posters indicated, but that's way too much work to do on a regular basis. The code output from Blend needs to compile and run as is or Blend's utility is limited. I hope this will be fixed before the version goes gold.

Hi Karen,

I see an error in the error list instead of a compile time warning:

Error 3 The attachable property 'VisualStateGroups' was not found in type 'VisualStateManager'. c:\tst\ModuleButton.xaml 8 7 CPWerxSilverlightPrototype

But you are right. Compilation and runtime behavior isn't affected.

Thanks

Hi Everyone, Just wanted to clarify....

The VisualStateManager.VisualStateGroups tag does give a compile-time warning in VisualStateManager. This error is a known tools issue, and does not affect actual compilation or runtime behavior. (If you attempt to compile the XAML with the VisualStateManager.VisualStateGroups tag in VS, it will compile successfully and run as expected.)

Thanks!

Karen

it's the same for me ..

Deep zoom does not work very well in blend and visual studio ...

It's very strange!

This was my original idea. We'll use a lot of UserControls which should have the same look & feel.

I use a GetStateManage function to reuse my states.

This is a interesting concept.
In theory you could then reuse the visual state you create in code in other places also.

Hi,

I've found another workaround to avoid the warning/error and the broken Design View inside Studio :

Design everything you need with Blend.
Comment out the VisualStateManager Part in the XAML file.
Create the VisualStateManager dynamically inside your code behind class

Regards,
Stefan

This is my XAML:
---------------------------

<vsm:VisualStateManager.VisualStateGroups>
            <vsm:VisualStateGroup x:Name="MouseOverStates">
                <vsm:VisualState x:Name="MouseEnter">
                    <Storyboard>
                        <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Duration="00:00:00.0010000" Storyboard.TargetName="LayoutRoot" Storyboard.TargetProperty="(UIElement.Opacity)">
                            <SplineDoubleKeyFrame KeyTime="00:00:00" Value="0.5"/>
                        </DoubleAnimationUsingKeyFrames>
                    </Storyboard>
                </vsm:VisualState>
                <vsm:VisualState x:Name="MouseLeave">
                    <Storyboard/>
                </vsm:VisualState>
</vsm:VisualStateGroup>

This is my code:
------------------------

Friend WithEvents vsMouseOverStates As System.Windows.VisualStateGroup

Friend WithEvents vsMouseEnter As System.Windows.VisualState

Friend WithEvents vsMouseLeave As System.Windows.VisualState

Public Sub New()
InitializeComponent()

vsMouseOverStates = New VisualStateGroup
    vsMouseEnter = New VisualState
    vsMouseLeave = New VisualState

Dim vsStoryboard As New Storyboard
    vsMouseOverStates.SetValue(NameProperty, "MouseOverStates")
    vsMouseEnter.SetValue(NameProperty, "MouseEnter")
    vsMouseLeave.SetValue(NameProperty, "MouseLeave")
    vsMouseOverStates.States.Add(vsMouseEnter)
    vsMouseOverStates.States.Add(vsMouseLeave)
    vsMouseEnter.Storyboard = vsStoryboard
    VisualStateManager.GetVisualStateGroups(LayoutRoot).Add(vsMouseOverStates)

    Dim vsDoubleAnimationUsingKeyFrames As New DoubleAnimationUsingKeyFrames
    vsDoubleAnimationUsingKeyFrames.BeginTime = New TimeSpan(0)
    vsDoubleAnimationUsingKeyFrames.Duration = New Duration(New TimeSpan(0, 0, 0, 0, 10))
    vsDoubleAnimationUsingKeyFrames.SetValue(Storyboard.TargetNameProperty, "LayoutRoot")
    vsDoubleAnimationUsingKeyFrames.SetValue(Storyboard.TargetPropertyProperty, New PropertyPath("Opacity"))
    vsStoryboard.Children.Add(vsDoubleAnimationUsingKeyFrames)

    Dim vsSplineDoubleKeyFrame As New SplineDoubleKeyFrame
    vsSplineDoubleKeyFrame.Value = 0.5
    vsSplineDoubleKeyFrame.KeyTime = KeyTime.FromTimeSpan(New TimeSpan(0))
    vsDoubleAnimationUsingKeyFrames.KeyFrames.Add(vsSplineDoubleKeyFrame)
End Sub

Simlar to Harlequin, I got it working today too. The VisualStateGroups line in the Xaml was underlined in Visual Studio with a compiler warning, but it runs and works as expected.

To upgrade from Beta1 Control Templates to Beta2 Control Templates, I just moved the code from the "Grid.Resources" Storyboards to the "vsm" code. Check out the SDK help file - they provide examples that you should be able to follow. Once I understood how to wire up the "vsm" XAML, it was a fairly simple, yet annoying, conversion.

There was some slight change in behavior with more complicated control templates, like the ToggleButton... but still, it was straightforward enough to figure out.

Never fear, I found the error of my ways. My disbaled rectange now has the same x:Name as the disabled visual state. Rectified and fixed.

Here is my Style from App.xaml. The vsm namespace is defined in the Application header. As soon as I use the vsm library in the style, my page no longer displays.

Re: Re: The attachable property 'VisualStateGroups' was not found in type 'VisualStateManager'.

Harlequin — Wed, 11 Jun 2008 20:07:23 GMT

vsm works for me. I do get the Xaml underlined on the VisualStateGroups line with that , but it compiles and works. Warning level of 4 on our Silverlight project.

Example code...

      <vsm:Setter Property="Template">
        <vsm:Setter.Value>
          <ControlTemplate TargetType="CheckBox">
            <Grid Cursor="Hand" Margin="0">
              <vsm:VisualStateManager.VisualStateGroups>
                <vsm:VisualStateGroup x:Name="CommonStates">
                  <vsm:VisualState x:Name="Checked">

codism:
I think your old styles and templates are no longer good any more. It's better to recreate them in expression. I see the code generated by blend, almost everything related to style and template is under vsm namespace.

It seems the only real change is that the state storyboards have moved from resources to vsm namespace. rather simple change to the styles. you're correct the old styles don't work, however the vsm namespace doesn't work either.
