Visual states are not running storyboards within a control template
Hi, I've run into an issue where I cannot run storyboards on a tab item as I switch their selected state.
This code snippet functions as expected within blend -- the selected tab item turns red when changing visual states.
However, in native noesis the storyboards are not run when changing visual states. Only the first tab item which is selected by default will turn red.
I've gotten around this issue for now by using Triggers.

Code: Select all
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Rectangle x:Name="Rect" Fill="Blue"/>
<ContentPresenter ContentSource="Header"/>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Selected">
<Storyboard Duration="0:0:1">
<ColorAnimation Storyboard.TargetName="Rect" Storyboard.TargetProperty="Fill.(SolidColorBrush.Color)" To="Red"/>
</Storyboard>
</VisualState>
<VisualState x:Name="Unselected"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

Re: Visual states are not running storyboards within a control template
I tried the following xaml in our Xamltoy and works as expected:
How are you switching the selected tab? In code or by clicking on it?
Which version of NoesisGUI are you using?

Re: Visual states are not running storyboards within a control template
Hi, thanks for the reply :)
The version of NoesisGUI that I am using is 3.1.5.
I'm changing the selected tab by modifying the SelectedIndex property directly in code behind, with focus disabled on the tab items themselves.
Currently I've got blend set up to listen to key presses for left and right which switches the SelectedIndex of the tab control.
Copying your example has the same incorrect behavior in game, whereas it works as expected in blend.
