Is it possible to add a border to a textblock. I need it to be added in the setter property below code:
<Style x:Key="notCalled" TargetType="{x:Type TextBlock}">
<Setter Property="Margin" Value="2,2,2,2" />
<Setter Property="Background" Value="Transparent" />
</Style>
You need to wrap your TextBlock in a Border. Example:
<Border BorderThickness="1" BorderBrush="Black">
<TextBlock ... />
</Border>
Of course, you can set these properties (BorderThickness, BorderBrush) through styles as well:
<Style x:Key="notCalledBorder" TargetType="{x:Type Border}">
<Setter Property="BorderThickness" Value="1" />
<Setter Property="BorderBrush" Value="Black" />
</Style>
<Border Style="{StaticResource notCalledBorder}">
<TextBlock ... />
</Border>
A TextBlock does not actually inherit from Control so it does not have properties that you would generally associate with a Control. Your best bet for adding a border in a style is to replace the TextBlock with a Label

I have set up the following control template and style as the default style for all Tooltips in my application:
<Style TargetType="{x:Type ToolTip}">
<!-- Background="Transparent" BorderBrush="Transparent" BorderThickness="0" HasDropShadow="True" -->
<Setter Property="Background" Value="Transparent" />
<Setter Property="BorderBrush" Value="Transparent" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="Placement" Value="Bottom"></Setter>
<Setter Property="BorderThickness" Value="0" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid Background="{Binding Source={x:Static visualResources:ThemeManager.Instance}, Path=ThemePageColor}" >
<ContentPresenter Margin="3"></ContentPresenter>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
(The code above is in the Window.Resources)
And inside the same window I have this control:
<Button ToolTip="Tooltip Text!" HorizontalContentAlignment="Right" Height="60" Click="_Button_AddCourse_Click"/>
But when I run my program the tooltips don't appear as they should! I Only can see an orange rectangle (which is the Grid in controltemplate , and orange is the ThemeManager.Instance.ThemePageColor property) , But there is no text inside the tooltip.
Thanks in advance.
Sorry was trying to do this from my phone in a hurry and threw it in the comment by mistake.
Anyway, just change <ControlTemplate> to <ControlTemplate TargetType="ToolTip"> so it knows what your ContentPresenter is even trying to talk to and you should be good.
Hope this helps, cheers!
P.S. - Mark answered questions as such so people know you got your issue resolved.
Is it possible to change the font color for the column headers in a datagrid?
I've already applied some styling which changes the background, but i can't figure out how to change the font color, not for the element, but for the header.
the XAML I'm using is from this thread: Change background color of Datagrid Header in Silverlight
Hi add a style to your resource and set the style,
<Style x:Key="GridHeaderStyle" ControlTemplate TargetType="primitives:DataGridColumnHeader">
<Setter Property="FontSize"
Value="14" />
<Setter Property="FontWeight"
Value="Bold" />
<Setter Property="Foreground"
Value="{StaticResource xrxGray_I}" />
<Setter Property="Background"
Value="{StaticResource xrxGray_B}" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Grid Height="50" Width="100">
<TextBlock Text="{TemplateBinding Header}" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
Here is the XAML in my application resources that globally changes all of the Button controls in the application to look and behave like I want:
<Style TargetType="{x:Type Button}" x:Key="MyButtonStyle">
<Setter Property="SnapsToDevicePixels" Value="true"/>
<Setter Property="OverridesDefaultStyle" Value="true"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Border" CornerRadius="0" BorderThickness="0"
Background="CornflowerBlue" BorderBrush="CornflowerBlue">
<ContentPresenter Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" RecognizesAccessKey="True" />
</Border>
<ControlTemplate.Triggers>
<!-- a bunch o' triggers here -->
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
On one of my application's user controls, I would like to change some properties of this button. Here is some XAML that I am using in the UserControl.Resources section now to do this:
<Style x:Key="SpecialButton" TargetType="Button" BasedOn="{StaticResource MyButtonStyle}">
<Setter Property="Width" Value="20" />
<Setter Property="Visibility" Value="Collapsed" />
<Setter Property="Content" Value=">" />
<Setter Property="Border" Value="#eeeeee" />
<Setter Property="Border.Background" Value="#eeeeee" />
</Style>
The Button controls on my UserControl that I assign the style to of SpecialButton have the correct width, visibility, and content, but these last two attempts do not work. How would I go about changing the background color of the Border with a name of "Border" from the application resource in this SpecialButton style?
What you can do is use TemplateBinding to set the Background property on the control, in the base style. Also in the base style, set the Background color to the default "CornflowerBlue".
<Setter Property="Background" Value="CornflowerBlue" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="Border" Background="{TemplateBinding Background}"
Now you can overwrite the Background in the derived style:
<Style x:Key="SpecialButton" TargetType="Button" BasedOn="{StaticResource MyButtonStyle}">
<Setter Property="Background" Value="#eeeeee" />
(Note that, if you want to use other properties that aren't defined on the Button control -- or, say you wanted to use multiple background colors -- then you'd have to create your own control that inherits Button, and expose the new properties as Dependency Properties.)
I'm trying to style an element in WPF which displays a yellow border around anything thats in it and shows a tool-tip when the cursor is over it. The problem is that I don't have much of an idea how to do this and anything I tried does not seem to work.
Here is what I have until now:
<Style x:Key="HistoryElementStyle"
TargetType="{x:Type Control}">
<Setter Property="BorderBrush"
Value="Yellow"/>
<Setter Property="BorderThickness"
Value="1.5" />
<Setter Property="CornerRadius"
Value="2" />
<Setter Property="ToolTip">
<Setter.Value>
<ToolTip Template="{StaticResource HistoryTooltipTemplate}" />
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ContentPresenter x:Name="PART_Content"
Width="Auto"
HorizontalAlignment="Stretch"
ContentSource="Content"
IsEnabled="{TemplateBinding IsEnabled}" />
</Setter.Value>
</Setter>
</Style>
Visual Studio complains that the ContentPresenter is an invalid type.

You must wrap the ContentPresenter around a <ControlTemplate TargetType="Control" /> to match the type of the Control.Template property.
I'd try adding the DataTempalte tag around the ContentPresenter (sorry, I cannot test from where I am writing this).
If I have the following style defined:
<UserControl.Resources>
<Style TargetType="TextBlock" x:Key="ProblemStyle">
<Setter Property="FontSize" Value="40"/>
<Setter Property="FontWeight" Value="Bold"/>
</Style>
</UserControl.Resources>
Then when I have a ContentPresenter data bound to a string, in WPF I can get it to style the text as required with the following XAML:
<ContentPresenter Content="{Binding Problem}">
<ContentPresenter.Resources>
<Style TargetType="TextBlock" BasedOn="{StaticResource ProblemStyle}" />
</ContentPresenter.Resources>
</ContentPresenter>
However, in Silverlight, this doesn't work. Is there a way that works for both?
Use the TextElement Attached property. You will not be able to set a style, but most of the properties that effects the Textblock are there..
<ContentPresenter x:Name="ContentPresenter"
ContentSource="Header"
HorizontalAlignment="Left"
TextElement.FontFamily="Segoe UI"
TextElement.FontSize="12"
TextElement.FontWeight="Bold"
TextElement.Foreground="White"
RecognizesAccessKey="True" />
First:
Make sure that your style "ProblemStyle" is being loaded before the application tries to render the ContentPresenter. In Silverlight, the order the styles are defined makes a difference, and if it has not been loaded first then it may not be reading anything.
Ok, I am going to run on some assumptions here, the first one being that you are using a ContentControl to display something and that the ContentPresenter is inside of this control.
But why not create a Style for the ContentControl?
<Style x:key="ProblemStyle" TargetType="ContentControl">
<Setter Property="FontSize" Value="40"/>
<Setter Property="FontWeight" Value="Bold"/>
</Style>
Then your ContentControl would have the Style set to the StaticResource of "ProblemStyle".
Since by default the template of a ContentControl has the ContentPresenter - or you can define the ContentPresenter template in the style as well:
<Style x:key="ProblemStyle" TargetType="ContentControl">
<Setter Property="FontSize" Value="40"/>
<Setter Property="FontWeight" Value="Bold"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ContentControl">
<Border>
<ContentPresenter Content="{TemplateBinding Content}"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The template there is just as a placeholder to give an idea of where it would/could be located.
