I had asked this question before, in regards to the AxisPanel:
Implicit styles not working in SciCharts WPF?
I'm starting to notice that there are more issues further down... not sure if this was fixed in the "last" update or not.
If I create an implicit style, say...
<Style TargetType="{x:Type SciCharts:SciChartSurface}" BasedOn="{x:Type SciCharts:SciChartSurface}">
<Setter Property="BorderBrush" Value="Red" />
</Style>
That the style is completely ignored. It's placed above the actual SciChart in the scheme of all things, such that my hierarchy is:
<SomeControl>
<SomeControl.Resources>
Implicit Styles Here
</SomeControl.Resources>
<Some Other Control />
<SciChartSurface />
</SomeOtherControl>
The BorderBrush itself is pulling from the DefaultStyle, supposedly (checking with Snoop) and not the ImplicitStyle (Snoop does a marvelous job of telling us which it pulls from -- but not where that Style is located). The BorderBrush is bound to the DefaultStyle and completely ignores whatever is set in the Implicit Style.
I'm not sure if there is something I'm missing, but the end result is that we have some application-wide settings we'd like to make to all of our SciCharts and very little support to do it, aside from literally having to specify a style on every element.
I'm curious if, per my last question (linked above), that this was a "large" issue for more than just AxisPanel and extended to all of the SciChart's controls/elements -- and more than just AxisPanel was updated to support DefaultStyleKey?
Thanks in Advance!
I found the error, in this case it appears to be between keyboard and chair :P
You need
<Style TargetType="{x:Type s:SciChartSurface}" BasedOn="{StaticResource {x:Type s:SciChartSurface}}">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="Margin" Value="10"/>
<Setter Property="BorderThickness" Value="10"/>
</Style>
not
<Style TargetType="{x:Type s:SciChartSurface}" BasedOn="{x:Type s:SciChartSurface}">
<Setter Property="BorderBrush" Value="Red" />
<Setter Property="Margin" Value="10"/>
<Setter Property="BorderThickness" Value="10"/>
</Style>
I put together an example showing how to set implicit styles on SciChartSurface, NumericAxis and AxisPanel here..
This contains how to set the style on the AxisPanel implicitly:
AxisBase.AxisPanelStyle was added in build v5.1.0.11306 as mentioned here.

I am new XAML however I am given the task to override some styles for certain elements within an existing application.
In my custom Theme, I am attempting to override the style of a BORDER control.
From what I can tell (using Snoop) to inspect the application, the element I want to change is just a plain border.
The border also seems to have a Name of "SubMenuBorder". Please see the image below.
Here is the latest iteration of my style snippet in which I am trying to set the border control's Background, BorderBrush and BorderThickness BUT ONLY if the control has a name of "SubMenuBorder"
<Style TargetType="{x:Type Border}">
<Style.Triggers>
<Trigger Property="Name" Value="SubMenuBorder">
<Setter Property="Background" Value="Red"></Setter>
<Setter Property="BorderBrush" Value="Red"></Setter>
<Setter Property="BorderThickness" Value="20"></Setter>
</Trigger>
</Style.Triggers>
</Style>
Unfortunately the above does NOT work.
The style trigger does not seem to fire/apply to the intended control.
If I simplify things further and just style ALL borders with the following snippet, then it seems to work and the border control I want to change, is styled, but so is every other border control in the application.
<Style TargetType="{x:Type Border}">
<Setter Property="Background" Value="Red"></Setter>
<Setter Property="BorderBrush" Value="Red"></Setter>
<Setter Property="BorderThickness" Value="20"></Setter>
</Style>
Further Findings
I attempted to use a DataTrigger... which unfortunately doesn't work either.
Snoop shows below that the data trigger is being satisfied, however on the second image below you can see that the property of the background and borderbrush are still from the parenttemplate.
Any ideas please?
<Style TargetType="{x:Type Border}">
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=Name}" Value="SubMenuBorder">
<Setter Property="Background" Value="Red"></Setter>
<Setter Property="BorderBrush" Value="Red"></Setter>
<Setter Property="BorderThickness" Value="20"></Setter>
</DataTrigger>
</Style.Triggers>
</Style>
You cannot use triggers to modify a Border that is defined in a ControlTemplate, with the exception of using an implicit Style that applies to all elements of the type specified by the TargetType property of the implicit Style.
You will either have to modify the ControlTemplate itself, or programmatically find the Border element in the visual tree and then change its runtime property values. The first approach, i.e. modifying or creating a custom template, is the recommended approach.
The name "SubMenuBorder" is only known and applicable within that Border element's namescope.
I use Telerik WPF controls and need to add a NumericUpDown control to my UI. The thing is when used "as it is" it doesn't fit the rest of the application visually
<TL;DR>
This is a bigger application, that's not been written fully by me. Other people somehow managed to "import" other telerik controls and assign them other styles. Sadly, nobody's used the UpDown control before.
</>
I added the control to my UI:
<telerik:RadNumericUpDown
Minimum="0"
Maximum="10"
SmallChange="1"
NumberDecimalDigits="0"
IsInteger="True"
Value="{Binding Path=Counter}" />
Also, I've added some styling to a ResourceDictionary:
<Style TargetType="{x:Type telerikInput:RadNumericUpDown}">
<Setter Property="Padding" Value="1"/>
<Setter Property="Margin" Value="2"/>
<Setter Property="Border.CornerRadius" Value="2" />
<Setter Property="Border.Background" Value="{StaticResource ControlBackgroundBrush}" />
<Setter Property="Border.BorderBrush" Value="{StaticResource SolidBorderBrush}" />
<Setter Property="Border.BorderThickness" Value="1" />
</Style>
And this handles some basic styling features (border, margin, etc). In general it looks "good enough". There's only one problem - when a mouse pointer hovers over the control, it becomes shiny and glossy. That's not like my other controls behave - is there an easy way to remove this effect ?
I've tried experimenting with Triggers:
<Style>
...
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="Red" />
<Setter Property="Border.BorderBrush" Value="Black" />
...
</Style.Triggers>
</Style>
But this didn't do much. I've also tried setting IncreaseButtonContentTemplate field, but this turned out no good either.
You need to modify the default ControlTemplates and remove any "shiny and glossy" effects from them. The easiest way to do this would be to copy the default templates from the Themes.Implicit folder in your Telerik installation directory into your solution and then edit them as per your requirements.
There is no "DisableEffects" property that you can simply set on the control I am afraid.
I met the same problem as Deactivate FocusVisualStyle globally.
But none of the answers can work.
So, I just want to set all the Controls in my application FocusVisualStyle="{x:Null}", any
effecive way to achieve this?
I don't want to set each control separately.
How about just putting this into your Application.Resources?:
<Style TargetType="{x:Type Control}">
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
To also affect non-controls as well, try this instead:
<Style TargetType="{x:Type FrameworkElement}">
<Setter Property="FocusVisualStyle" Value="{x:Null}" />
</Style>
As Control is derived from FrameworkElement, they will all use this Style also.
I am currently working on creating a theme for charts.
Beside other things, I want to make the bars in BarSeries have a flat look(without borders).
I want to make it to work with implicit styling so I added a Style to BarDataPoint(without a Key because it needs to work by implicit styling) but it is not applied.
Any idea why is it is not applied?
Is it because of DataPointStyle style from Palette which is applied instead?
What I am trying to do is to change the look of the BarDataPoint but still have the colors from the palette applied. And also try to make this work by pure XAML(if possible).
In order to make this work, the only way I see is by changing DataPointStyle(in each ResourceDictionary from Chart.Palette) to have TargetType set to BarDataPoint and Template set to my template implementation:
<toolkit:Chart.Palette>
<toolkit:ResourceDictionaryCollection>
<ResourceDictionary>
<Style x:Key="DataPointStyle" TargetType="toolkit:BarDataPoint" BasedOn="{StaticResource BarDataPointStyle}">
<Setter Property="Background" Value="Yellow" />
<Setter Property="BorderBrush" Value="Black" />
</Style>
</ResourceDictionary>
<ResourceDictionary>
<Style x:Key="DataPointStyle" TargetType="toolkit:BarDataPoint" BasedOn="{StaticResource BarDataPointStyle}">
<Setter Property="Background" Value="Red" />
<Setter Property="BorderBrush" Value="Black" />
</Style>
</ResourceDictionary>
</toolkit:ResourceDictionaryCollection>
</toolkit:Chart.Palette>
But since this is for implicit style for Chart control, how would that work if I have a Char control with a different type of series, for example a Chart with ColumnSeries? I don't think the DataPointStyle will work in this case because it is targeting the BarDataPoint type(I suppose the app will crash).
Am I forced to create different Chart styles with different keys(each style having DataPointStyle changed to target different control template)?
But then, how will that work for a Chart control with several different series?
I also tried to use an implicit style for toolkit:BarDataPoint in the palette's resource dictionary like this, but without success:
<Setter Property="Palette">
<Setter.Value>
<toolkit:ResourceDictionaryCollection>
<ResourceDictionary>
<SolidColorBrush x:Key="Background"
Color="#FFCA294D" />
<Style TargetType="toolkit:BarDataPoint">
<Setter Property="Template"
Value="{StaticResource BarDataPointTemplate}" />
<Setter Property="Background"
Value="{StaticResource Background}" />
</Style>
I tried to look to themes like JetPack but they don't seem to do what I want.
Thanks!
sorry for late update.

Silverlight 4: Chart Toolkit Color Set
I am trying to make the column header of my WPF Datagrid to be transparent.
I am able to set it to a color without problem, but I can't have it transparent. Here is what I tried:
<Style x:Key="DatagridColumnHeaderStyle" TargetType="{x:Type tk:DataGridColumnHeader}">
<Setter Property="Background" Value="Transparent" />
<Setter Property="Foreground" Value="#C2C4C6" />
</Style>
<Style x:Key="DashboardGridStyle" TargetType="{x:Type tk:DataGrid}">
<Setter Property="ColumnHeaderStyle" Value="{StaticResource DatagridColumnHeaderStyle}" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="RowBackground" Value="Transparent" />
</Style>
<tk:DataGrid Style="{StaticResource DashboardGridStyle}" >
...
</tk:DataGrid>
With this code, it seems to take the default brush.
What am I missing?
I used Snoop to take a look at what was happening. It seems that another DataGridColumnHeader is always created behind the one you can modify, and it's not affected by changes on styles. When you set a transparent background, in fact is being correctly applied, so what you see is that ghost header behind (which has the usual grey background).
If you apply a coloured background and play with Opacity, you will see how the two colours are mixed. I don't know if this can be solved.
With the answer from Natxo (thanks!), I was able to find a solution. And it is a simple one too!
Knowing that there was another DataGridColumnHeader behind the one we can modify through the ColumnHeaderStyle, I just had to set a style that will affect all DataGridColumnHeader:
<Style TargetType="{x:Type tk:DataGridColumnHeader}">
<Setter Property="Background" Value="Transparent" />
</Style>
