Problems with WPF ToolTipService properties (BetweenShowDelay, etc.) in Microsoft.Windows.Controls.Ribbon control

I have an very, very huge application in WPF with a Ribbon in it. The ribbon contain a bunch of RibbonControls, each binded to a different command. On every control, we put a ToolTip. We overrided these ToolTip templates to use a control of our own, which gives more information. We could call il a superToolTip.

The override of the tooltip templates is working just fine. Now we want to unify the way the tooltips are showing. What I mean is we want the same initialShowDelay, ShowDuration, etc., for every single tooltips in the application (there are tooltips elsewhere than in the ribbon, which use the same home made control that the ones of the ribbon). So, I binded the ToolTipService.InitialShowDelay, ToolTipService.BetweenShowDelay, ToolTipService.ShowDuration properties to global constants in the application.

InitialShowDelay : The property InitialShowDelay is working just fine for almost every control in the application... The only one not working is RibbonSplitButton, which keep the default value of 400...

BetweenShowDelay : The property BetweenShowDelay is working just fine when the tooltip is on a ListBoxItem... but not working in the Ribbon nor in a complex control of our own (a Property Grid).

These properties are set in the control on which the tooltip is set, and not on the tooltip themselves.

I honestly have absolutely no idead why it is behaving this way... Anyone has any idea on what could cause this or how to solve it?

If you need more information, do not hesitate to ask, i really am desperate about this.

Thank you very much!

Solution

The problem was that the condition for BetweenShowDelay wasn't respected, you need to have a value set for the property "ToolTip", in this case you were using a template, so the value was at null. You can resolve it this way :

<Style x:Key="{x:Type ToolTip}" TargetType="ToolTip">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ToolTip">
                    <Utils:ToolTipControl DataContext="{Binding ToolTipInfo}"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

and then place the dummy in the specified button :

    <!-- RibbonButton -->
<Style TargetType="{x:Type ribbon:RibbonButton}" BasedOn="{StaticResource RibbonControlStyle}"  >

    <Style.Triggers>
        <DataTrigger Value="true" >
            <DataTrigger.Binding>
                <Binding Converter="{StaticResource IsBoundConverter}" />
            </DataTrigger.Binding>
            <Setter Property="Command" Value="{Binding}" />
            <Setter Property="ribbon:RibbonControlService.Label" Value="{Binding Name}" />
            <Setter Property="ribbon:RibbonControlService.SmallImageSource" Value="{Binding Icon}" />
            <Setter Property="ribbon:RibbonControlService.LargeImageSource" Value="{Binding LargeIcon}" />
            <Setter Property="Visibility" Value="{Binding Visibility}" />
            <Setter Property="ToolTip" Value="dummy"/> <!-- Use dummy value to force tooltip to show and to Bind the tooltip-->
        </DataTrigger>
        <DataTrigger Value="false" >
            <DataTrigger.Binding>
                <Binding Converter="{StaticResource IsBoundConverter}" />
            </DataTrigger.Binding>
            <Setter Property="Background" Value="#FF900000" />
        </DataTrigger>
    </Style.Triggers>



</Style>

That way the dummy value will be override.
