[Unity] Setting GridLength in Storyboard

18 Sep 2014, 10:57

Hi,

I'm trying to set the Width/Height of Row/ColumnDefinition of a Grid in a VisualState:

<VisualState x:Name="Landscape">
    <Storyboard>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="col1" 
                                       Storyboard.TargetProperty="Width">
            <DiscreteObjectKeyFrame KeyTime="0">
                <DiscreteObjectKeyFrame.Value>
                    <GridLength>3*</GridLength>
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
        </ObjectAnimationUsingKeyFrames>
        <ObjectAnimationUsingKeyFrames Storyboard.TargetName="row1" 
                                       Storyboard.TargetProperty="Height">
            <DiscreteObjectKeyFrame KeyTime="0">
                <DiscreteObjectKeyFrame.Value>
                    <GridLength>*</GridLength>
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</VisualState>

This works with wpf but in unity I get the following error:

[DX9] Assets/_Project/Xaml/GuiTest_2.xaml
Type 'GridLength' is not registered for boxed serialization
UnityEngine.Debug:LogError(Object)
Noesis.BuildToolKernel:OnLog(Int32, String) (at Assets/Editor/NoesisGUI/NoesisBuildToolKernel.cs:194)

UnityEditor.AssetPostprocessingInternal:PostprocessAllAssets(String[], String[], String[], String[], String[])

Is this a bug I should report or is this by design?
Is there another way to achive this behavior?

It was a bug, will be fixed for the next release.

Meanwhile you will have to change Row/Column definition in code:

ColumnDefinition col = grid.GetColumnDefinitions().Get(0).As<ColumnDefinition>();
col.SetWidth(new GridLength(3.0f, GridUnitType.Star));
