Refreshing a binding that uses a value converter within a style - wpf

Question

I am using a Telerik RadTimeline control in my project, I have a template for the TimelineItemTemplate:
<telerik:RadTimeline x:Name="myTimeline"
PeriodStart="{Binding PeriodStart}"
PeriodEnd="{Binding PeriodEnd}"
VisiblePeriodStart="{Binding VisiblePeriodStart, Mode=TwoWay}"
VisiblePeriodEnd="{Binding VisiblePeriodEnd, Mode=TwoWay}"
StartPath="StartDate"
DurationPath="Duration"
GroupPath="Title"
GroupExpandMode="Multiple"
ItemsSource="{Binding myData}"
TimelineItemTemplate="{StaticResource myTemplate}"
ScrollMode="ScrollOnly"
IsSelectionEnabled="True" SelectionMode="Extended"
DataContext="{Binding ElementName=vm}">
</telerik:RadTimeline>
My template is the next:
<DataTemplate x:Key="myTemplate">
<controls:CustomTimelineControl Style="{StaticResource myStyle}"/>
</DataTemplate>
And my style:
<Style x:Key="myStyle" TargetType="controls:CustomTimelineControl">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="controls:CustomTimelineControl">
<Border Height="{Binding Source={StaticResource odpSettings}, UpdateSourceTrigger=, Converter={StaticResource visibleToHeightConverter3}, ConverterParameter=Largos}" Margin="{Binding Source={StaticResource odpSettings},Path=ItemBorderMargin,Mode=OneWay}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="largosHeatItem" Storyboard.TargetProperty="Background" Duration="0.00:00:00.05">
<DiscreteObjectKeyFrame KeyTime="0.00:00:00.0" Value="{StaticResource HeatItem_Background_MouseOver}" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames Storyboard.TargetName="largosHeatItem" Storyboard.TargetProperty="Background" Duration="0.00:00:00.05">
<DiscreteObjectKeyFrame KeyTime="0.00:00:00.0" Value="{StaticResource HeatItem_Background_MouseOver}" />
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border x:Name="largosHeatItem" Height="{Binding Source={StaticResource odpSettings}, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource visibleToHeightConverter2}, ConverterParameter=Largos}"
Margin="0, 0, 0, 0" Background="{Binding DataItem.Status, Converter={StaticResource typeToColorConverter}}">
<TextBlock Text="{Binding DataItem.HeatId}"
FontFamily="Segoe UI"
Foreground="{StaticResource HeatItem_Foreground}"
FontSize="{Binding Source={StaticResource odpSettings}, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource visibleToFontSizeConverter}}"
Height="{Binding Source={StaticResource odpSettings}, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource visibleToHeightConverter1}, ConverterParameter=Largos}"
TextAlignment="Center"/>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
I have converters for the borders height, textblock size and height, as value I am sending an object that contains several properties in order to set the correct value, for example:
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
AppSettings objSettings = value as AppSettings;
double val = 0;
if (parameter != null && parameter is string)
{
switch((string)parameter)
{
case "Planos":
if(objSettings.BothGantt)
val= objSettings.PlanosItemHeight1;
else
val= objSettings.PlanosItemHeightMax1;
break;
case "Largos":
if(objSettings.BothGantt)
val= objSettings.LargosItemHeight1;
else
val= objSettings.LargosItemHeightMax1;
break;
}
}
return val;
}
opdSettings is an ObjectDataProvider:
<ObjectDataProvider x:Key="odpSettings" ObjectType="{x:Type src:AppSettings}"/>
When the application is loaded, the control is shown correctly, but then when the appication is running I need to change some properties of odpSettings that affects the Timeline layout but it doesn't show the new values.
Is there a way to "refresh" the converters binding so the control shows the changes? I tried to use UpdateSourceTrigger=PropertyChanged but it didn't work.
Or is there another way to accomplish my goal?
Thanks in advance.
