Combine DataTrigger and Trigger in a MultiDataTrigger - wpf

I've seen from some examples that it is possible to combine this kind of trigger:
<Trigger Property="IsMouseOver" Value="True">
With this kind of data trigger :
<DataTrigger Binding="{Binding IsHighlightable}" Value="True" />
By using a MultiDataTrigger like this:
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsMouseOver}" Value="True"/>
<Condition Binding="{Binding IsHighlightable}" Value="True" />
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="#BF6DBDD1"/>
<Setter Property="Background" Value="{StaticResource SelectedItemBackgroundBrush}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
However, this does not work with attached properties. This trigger works:
<Trigger Property="UI:TreeViewHelper.IsMouseDirectlyOverItem" Value="True">
But this does not work:
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=UI:TreeViewHelper.IsMouseDirectlyOverItem}" Value="True"/>
<Condition Binding="{Binding IsHighlightable}" Value="True" />
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="#BF6DBDD1"/>
<Setter Property="Background" Value="{StaticResource SelectedItemBackgroundBrush}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
Is there a way I could make the trigger work correctly inside the MultiDataTrigger? The IsMouseDirectlyOverItem property was taken from here http://blogs.msdn.com/b/mikehillberg/archive/2006/09/21/mytreeviewhelperismousedirectlyoveritem.aspx.
Thanks


The syntax for attached properties is different:
Path=(UI:TreeViewHelper.IsMouseDirectlyOverItem)


<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding IsHighlightable}" Value="True"/>
<Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsMouseOver}" Value="True"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="BorderBrush" Value="#BF6DBDD1"/>
<Setter Property="Background" Value="{StaticResource SelectedItemBackgroundBrush}"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>

Modify only combobox toggle button template and leave all the rest as by design

I am trying to modify the combobox toggle button making it without borders and with transparent background.
I know that you can right click the combobox in the designer and choose "Edit Template --> Edit a copy" and VS generate all the code for you automatically. Then you can touch things as you want to get the desired look and feel.
This is just what I have done, but from that large code generated I only needed to touch the template for the ToggleButton and only below properties with below values to get the look and feel i wanted:
Background="Transparent"
BorderThickness="0"
BorderBrush="Transparent"
And then I have got the look and feel I wanted. The rest of stuff, triggers, etc.. and also other generated code (a lot) not posted here I hadn't to touch anything.
So my question is, is it possible to create a custom style for the togglebutton based on the default one and just modify those properties above indicated that i need? so I don't need to include all this generated code in my solution for only three properties i needed to modify.
Below I post only a piece of the code generated automatically by VS (you can see that I have set only above properties):
<Style x:Key="ComboBoxToggleButton" TargetType="{x:Type ToggleButton}">
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="IsTabStop" Value="false"/>

WPF TabControl header border

how can I remove the border arround the TabControll headers?
I uploaded an Image for you: http://fs5.directupload.net/images/161223/plbcwuyv.png
<Style TargetType="{x:Type TabItem}" x:Key="tabStyle" BasedOn="{StaticResource baseStyle}">
<Setter Property="Padding" Value="5" />
<Setter Property="FontSize" Value="14px" />
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="Typography.Capitals" Value="AllSmallCaps" />
</Style>
Markup
<TabControl x:Name="tabControl" Grid.Row="1" BorderThickness="0">
<TabItem Header="TabItem" Style="{StaticResource tabStyle}">
<Grid Background="white" Margin="-3" />
</TabItem>
<TabItem Header="TabItem">
<Grid Background="white"/>
</TabItem>
</TabControl>

The value of the BorderThickness property is hardcoded in the default ControlTemplate of the TabItem. You will have to modify the template in order to be able to change it.
You could copy the default template into your XAML markup by right-click on the TabItem in design mode in Visual Studio or in Blend and then choose Edit Template->Edit a Copy. You will then have to change the the BorderThickness property of the Border elements in the template. Remember to get rid of or change the MultiDataTriggers that sets the BorderThickness of the "innerBorder" and "mainBorder" elements of the TabItem when certain conditions.
Here is something that should get you started:
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">

I am afraid that there is no easier way to get rid of the borders than to modify the control template.

WPF Multitrigger Can't be null

This is my Multitrigger:
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Path=Dringlichkeit, RelativeSource={RelativeSource Self}}" Value="Normal"/>
<Condition Property="ItemsControl.AlternationIndex" Value="0"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="LightPink"/>
</MultiDataTrigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Path=Dringlichkeit, RelativeSource={RelativeSource Self}}" Value="Normal"/>
<Condition Property="ItemsControl.AlternationIndex" Value="1"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="Pink"/>
</MultiDataTrigger>
If I use this trigger as a DataTrigger, the binding works.
But I need the AlternationIndex. I thought it was because I was loading the data via SQL, but when I load the style after SQL, I still have the problem that the binding has a NULL value.

From documentation I can read that you should refer to your AlterationIndex like so:
{Binding RelativeSource={RelativeSource Self}, Path=(ItemsControl.AlternationIndex)}

Add unread notification to wpf microsoft ribbonbutton image

I want to ask the same question as Coxy: I want to show number of unread items on top of the image of an RibbonButton.
Example:
Can I do it without modifying a copy of the entire template? The reason that I am asking the same question again is that I am using the Microsoft Ribbon control and the solution given from Coxy question, can only be applied to the Ribbon control from Telerik.

I'm adding this in an answer because it's too long to put in a comment.
I went to the Microsoft Download site & downloaded the Ribbon control's source from here. The complete template with all of the triggers are in there. I won't paste any of it in here as it's copyrighted, but anybody can download it and install it. I think.
The installer installs a zip file with the source in the C:\Program Files (x86)\MicrosoftRibbonForWPF folder. I extracted the zip file into a VS project folder.
The template I'm looking at is in the v4.0\Themes\Generic.xaml file.
Those bad triggers do indeed reference the same property. It's the HighContrast property of the SystemParameters2.Current static object.
You can probably put together a custom template for your application that does not even use those triggers. At least, that's what I would do.

Martin Andersen is right: it is currently not possible to create a ribbon button in XAML, right-click it in the Document Outline window, select Edit template and create a copy of it. VS will display the following error message and no template is generated:
If you do the same thing in Blend, the same error message occurs, but a control template for the ribbon button will actually be generated. Unfortunately, this template is erroneous. It contains several triggers whose Binding bind to (0). Here is an example of such an erroneous trigger.
<DataTrigger Binding="{Binding (0)}" Value="True">
<Setter Property="TextElement.Foreground" TargetName="OuterBorder" Value="{DynamicResource {x:Static SystemColors.MenuTextBrushKey}}"/>
<Setter Property="Background" TargetName="OuterBorder" Value="Transparent"/>
<Setter Property="BorderBrush" TargetName="OuterBorder" Value="Transparent"/>
<Setter Property="CornerRadius" TargetName="OuterBorder" Value="0"/>
</DataTrigger>
This issue was also reported to Microsoft: https://connect.microsoft.com/VisualStudio/feedback/details/794891/problems-styling-wpf-4-5-ribbon-control
They provide the default control templates as attachments to this issue but unfortunately I cannot download them. The resulting file is always empty (zero kilobyte). Can anybody of you download it?
Proposed Solution
My current advise is to encapsulate the button within another custom control that derives from ContentControl and handles all the notification bubble. You then can set the button as the content of this new control. I'm currently working on an example - I will update this post when I find something useful.

WPF: Condition Binding versus Property, XamlParseException using either

I'm having trouble with a Condition for a MultiTrigger. If I do the following:
<Condition Binding="{Binding RelativeSource={RelativeSource
AncestorType={x:Type ListView}}}" Property="IsEnabled" Value="True"/>
Then I get this exception:
Condition cannot use both Property and Binding. Error at object 'System.Windows.Condition' in markup file
However, when I do the following:
<Condition Binding="{Binding RelativeSource={RelativeSource
AncestorType={x:Type ListView}}, Path=IsEnabled}" Value="True"/>
Then I get this exception:
Must specify both Property and Value for Trigger. Error at object 'System.Windows.Condition' in markup file
What gives? If it matters, here's the entire trigger:
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Binding="{Binding Path=IsSelected}" Value="True"/>
<Condition Binding="{Binding Path=ItemsControl.AlternationIndex}"
Value="0"/>
<Condition Binding="{Binding RelativeSource={RelativeSource
AncestorType={x:Type ListView}}, Path=IsEnabled}"
Value="True"/>
</MultiTrigger.Conditions>
<Setter Property="Background"
Value="{StaticResource evenSelected}" />
<Setter Property="BorderBrush"
Value="{StaticResource evenSelectedBorder}" />
</MultiTrigger>

The API in this case is confusing. Condition is used for two different types of multi-triggers, and the properties used are different. When using MultiTrigger, you will use the Property and Value properties. When using MultiDataTrigger (which is what you need), you specify a Binding and a Value. So, if you just switch your code to use a MultiDataTrigger, you'll be good to go:
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding Path=IsSelected}" Value="True"/>
<Condition Binding="{Binding Path=ItemsControl.AlternationIndex}"
Value="0"/>
<Condition Binding="{Binding RelativeSource={RelativeSource
AncestorType={x:Type ListView}}, Path=IsEnabled}"
Value="True"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background"
Value="{StaticResource evenSelected}" />
<Setter Property="BorderBrush"
Value="{StaticResource evenSelectedBorder}" />
</MultiDataTrigger>
