Please i need a way to come up with a style like these
But this is the current one i'm using
Please if you can help out with maybe a Link, Code, Tutorial on how to get it done, i'll greatly appreciate. Thanks..
Modifying the styles of a MenuItem (WPF) is more complicated than it might seem, because the same MenuItem control uses different templates depending on the Role assigned to each MenuItem: SubmenuItem, TopLevelHeader and SubmenuHeader.
With the menu bar you should not have any problem: if you want, you can define your style and your template as with any other control. For MenuItem, try something like this:
<ControlTemplate x:Key="{x:Static MenuItem.SubmenuItemTemplateKey}" TargetType="{x:Type local:MyMmenuItem}">
...
</ControlTemplate>
<ControlTemplate x:Key="{x:Static MenuItem.TopLevelHeaderTemplateKey}" TargetType="{x:Type local:MyMenuItem}">
...
</ControlTemplate>
<ControlTemplate x:Key="{x:Static MenuItem.SubmenuHeaderTemplateKey}" TargetType="{x:Type local:MyMenuItem}">
...
</ControlTemplate>
And to switch between different templates, we will use the RoleProperty dependency property, defining these triggers in our style:
<Style x:Key="MyMenuItemStyle" TargetType="{x:Type local:MyMenuItem}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Style.Triggers>
<Trigger Property="Role" Value="TopLevelHeader">
<Setter Property="Template" Value="{StaticResource {x:Static MenuItem.TopLevelHeaderTemplateKey}}"/>
</Trigger>
<Trigger Property="Role" Value="TopLevelItem">
<Setter Property="Template" Value="{StaticResource {x:Static MenuItem.TopLevelItemTemplateKey}}"/>
</Trigger>
<Trigger Property="Role" Value="SubmenuHeader">
<Setter Property="Template" Value="{StaticResource {x:Static MenuItem.SubmenuHeaderTemplateKey}}"/>
</Trigger>
<Trigger Property="Role" Value="SubmenuItem">
<Setter Property="Template" Value="{StaticResource {x:Static MenuItem.SubmenuItemTemplateKey}}"/>
</Trigger>
</Style.Triggers>
</Style>
I hope this works for you; It worked for me when I faced the same problem.
Good luck, good code.

I'm relatively new to WPF and XAML, and I'm trying to override the style of the TabItems in my TabControl. At the top of my xaml file I have this:
<Window.Resources>
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="0,5,0,0" Background="Transparent"
BorderBrush="LightGray" BorderThickness="1,1,1,1">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header" Margin="12,2,12,2"
RecognizesAccessKey="True">
</ContentPresenter>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100"/>
<Setter TargetName="Border" Property="Background" Value="#EEE9ED"/>
<Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,1"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter Property="IsEnabled" Value="False"/>
<Setter TargetName="Border" Property="Background" Value="LightGray"/>
<Setter TargetName="Border" Property="BorderBrush" Value="Black"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="FontSize" Value="15"/>
<Setter Property="FontWeight" Value="Bold"/>
</Style>
</Window.Resources>
It applies the style to all TabItems, and that works. It all looks how I want it to. The problem is that now I can't click on any of them. It doesn't look like any of the style guides online have encountered this problem, so it's probably just something really stupid that I'm doing, but I really can't figure it out.
The problem is <Setter Property="IsEnabled" Value="False"/>. A TabItem with IsEnabled set to False cannot be selected. Since all non-selected TabItems are disabled by your Style, this prevents any of them from being selected.
I have some styles and templates in App.Xaml so I can acces them thru multiple UserControls.
EDIT : This is within the app.Xaml:
One of the Styles are :
<Application x:Class="BaseRefence.generatingAnnotation.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:BaseRefence.generatingAnnotation"
xmlns:Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero2"
StartupUri="MainWindow.xaml">
<Application.Resources>
<Style x:Key="ComboBoxStyleRounded" TargetType="{x:Type ComboBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Border CornerRadius="25"
BorderThickness="1,1,2,2">
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
<Setter Property="Background" Value="{StaticResource ComboBox.Static.Background}"/>
<Setter Property="BorderBrush" Value="#42536b"/>
<Setter Property="Foreground" Value="Black"/>
<Setter Property="BorderThickness" Value="1,1,2,2"/>
<Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/>
<Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/>
<Setter Property="Padding" Value="6,3,5,3"/>
<Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
<Setter Property="ScrollViewer.PanningMode" Value="Both"/>
<Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
<Setter Property="Template" Value="{StaticResource ComboBoxTemplate}"/>
<Style.Triggers>
<Trigger Property="IsEditable" Value="true">
<Setter Property="IsTabStop" Value="false"/>
<Setter Property="Padding" Value="2"/>
<Setter Property="Template" Value="{StaticResource ComboBoxEditableTemplate}"/>
</Trigger>
</Style.Triggers>
</Style>
</Application.Resources>
</Application>
And in de UserControl.Xaml I have:
<ComboBox ItemsSource="{Binding ViewFamilyTypesInProject}"
SelectedItem="{Binding SelectedViewFamilyType, Mode=TwoWay}"
Grid.Row="1"
Grid.Column="1"
Margin="10 5"
MaxHeight="40"
Style="{DynamicResource ComboBoxStyleRounded}">
Within the designer everything works great, it shows correctly and all.
However, whenever I build and run my code, it gives the message and it does not override the style but keeps the default style.
System.Windows.ResourceDictionary Warning: 9 : Resource not found; ResourceKey='ComboBoxStyleRounded'
My experience: I frequently have same issues (using VS 16.6.2, .NET Core 3.1 and WPF).
Simply close Visual Studio and restart it: 98% of the times error disappears (will reappear sometime in the future).
You have an invalid Style. It may compile, as the XAML is syntactically correct, but the semantics of the markup are wrong. Since you are referencing the Style using DynamicResource the error occurs at runtime. But I wonder why don't get a XAML Designer error.
You are setting the ComboBox.Template property twice. Moreover and most important, the first ControlTemplate at the top of the Style is targeting the wrong type TextBox:
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Border CornerRadius="25"
BorderThickness="1,1,2,2">
</Border>
</Grid>
</ControlTemplate>
The type must be of course <ControlTemplate TargetType="ComboBox">.
Since you are referencing a ControlTemplate resource later
<Setter Property="Template" Value="{StaticResource ComboBoxTemplate}" />
I think you want to remove the first ControlTemplate. If you want to change the appearance of the TextBox, you would need to override the complete ControlTemplate of the ComboBox.
You may should run Clean Solution and Rebuild Solution.
I'm relative new to WPF and I have check on several tutorials on how to style a DataGrid. All of them use the same examples but when I try to implement them into my project, came this annoying message.
This is the code I've been trying to implement, I got this from MSDN page:
<Window.Resources>
<!-- DataGrid style -->
<Style x:Key="DataGridStyle1" TargetType="{x:Type DataGrid}">
<Setter Property="ColumnHeaderStyle" Value="{DynamicResource ColumnHeaderStyle1}"/>
</Style>
<!-- DataGridColumnHeader style -->
<Style x:Key="ColumnHeaderStyle1" TargetType="DataGridColumnHeader">
<Setter Property="Height" Value="30"/>
<Setter Property="Background" Value="LightBlue"/>
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="FontSize" Value="18" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="ToolTip" Value="Click to sort."/>
</Trigger>
</Style.Triggers>
</Style>
I'm using:
- C# Framework 4.5.1
- Blend for Visual Studio 2013
- Visual Studio 2013 (I got the error in both places).
All the imports and references are just fine.
I have check the solution properties and my Platform Target is "Any CPU"
My guess is this property might be deprecated for this control (DataGridColumnHeader).
Hope anyone could tell the proper way to acheive my goal.
Thanks in advance
It's trying to use a DynamicResource before it's defined.. Try swapping the Styles. Also, there's really no need for a DynamicResource here IMO, just change it to StaticResource.
<Window.Resources>
<!-- DataGridColumnHeader style -->
<Style x:Key="ColumnHeaderStyle1" TargetType="DataGridColumnHeader">
<Setter Property="Height" Value="30"/>
<Setter Property="Background" Value="LightBlue"/>
<Setter Property="Foreground" Value="Blue"/>
<Setter Property="FontSize" Value="18" />
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="ToolTip" Value="Click to sort."/>
</Trigger>
</Style.Triggers>
</Style>
<!-- DataGrid style -->
<Style x:Key="DataGridStyle1" TargetType="{x:Type DataGrid}">
<Setter Property="ColumnHeaderStyle" Value="{StaticResource ColumnHeaderStyle1}"/>
</Style>
</Window.Resources>
I am working in WPF with the MaterialDesign Toolkit and Dragablz.
I encountered a problem while trying to style a TabablzControl.
I already have style for the windows default TabControl and TabItem header, as shown in the picture:
http://i.imgur.com/2anl5rl.png
But when I change the default tabControl to TabablzControl, it turns into this:
http://i.imgur.com/bhaaMVy.png
Here are the window.resources:
<Style x:Key="mdTabControl" TargetType="TabControl">
<Setter Property="TextElement.Foreground" Value="{DynamicResource MaterialDesignBody}"/>
<Setter Property="Background" Value="{DynamicResource MaterialDesignPaper}"></Setter>
</Style>
<Style x:Key="mdTabHeader" TargetType="{x:Type TabItem}">
<Setter Property="Background" Value="{DynamicResource MaterialDesignPaper}"></Setter>
<Setter Property="Foreground" Value="{DynamicResource MaterialDesignBody}"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="1,0,1,0" CornerRadius="3 3 0 0">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
HorizontalAlignment="Center"
ContentSource="Header" Margin="10,2,10,2"
RecognizesAccessKey="True">
</ContentPresenter>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="Background" Value="{StaticResource SecondaryAccentBrush}" />
<Setter Property="Foreground" Value="{StaticResource SecondaryAccentForegroundBrush}"/>
</Trigger>
<Trigger Property="IsSelected" Value="False">
<Setter Property="Panel.ZIndex" Value="100" />
<Setter TargetName="Border" Property="Background" Value="{StaticResource PrimaryHueMidBrush}" />
<Setter Property="Foreground" Value="{StaticResource PrimaryHueMidForegroundBrush}"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Border" Property="Background" Value="{StaticResource PrimaryHueDarkBrush}" />
<Setter Property="Foreground" Value="{StaticResource PrimaryHueDarkForegroundBrush}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
The error appears when I change the mdTabControl style targetType to:
TargetType="dbz:TabablzControl"
I want to keep the style I set to the TabControl, but with the added functionality of the TabablzControl
Any help will be appreciated
First thing to note, which is a general WPF characteristic, you are not using style inheritance correctly.
As you are using Material Design with Dragablz, if you are restyling the tab control itself, you must inherit from the Material Design style in the Dragablz assembly using BasedOn:
<Style x:Key="mdTabControl" TargetType="TabControl" BasedOn="{StaticResource MaterialDesignTabablzControlStyle}">
<Setter Property="TextElement.Foreground" Value="{DynamicResource MaterialDesignBody}"/>
<Setter Property="Background" Value="{DynamicResource MaterialDesignPaper}"></Setter>
</Style>
Again, with the tab header itself, you need to inherit from the relevant style:
<Style x:Key="mdTabHeader" TargetType="{x:Type TabItem}" BasedOn="{StaticResource MaterialDesignDragableTabItemStyle}">
. . .
</Style>
Note, that (depending you your App.xaml setup) you probably need to make sure the correct resource dictionary is included in the same XAML file. For example a more complete XAML might be:
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="pack://application:,,,/Dragablz;component/Themes/materialdesign.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="NormalTabItemStyle" TargetType="{x:Type dragablz:DragablzItem}" BasedOn="{StaticResource MaterialDesignDragableTabItemStyle}">
<Setter Property="Width" Value="280" />
<Setter Property="Padding" Value="1" />
</Style>
. . .
</ResourceDictionary>
</Window.Resources>
Finally, as you are changing the TabItem style, you either need to the TabablzCOntrol style the correct style, or you could use it where you actually declare the TabablzControl itself:
<dragablz:TabablzControl ItemContainerStyle="{StaticResource mdTabHeader}" />
A good example of all this in action is in the SidePanels project in the demo solution at: https://github.com/ButchersBoy/DragablzSamplez
<Style TargetType="{x:Type dragablz:TabablzControl}" BasedOn="{StaticResource MaterialDesignTabablzControlStyle}"/>
I am using the Xceed data grid control and I am trying to change the header colors, but seem to be having some trouble. What I have right now is the following code snippet:
Style style = new Style(typeof(ColumnManagerRow));
style.Setters.Add(new Setter(ColumnManagerRow.BackgroundProperty, Brushes.Black));
this.grid.Resources[typeof(ColumnManagerRow)] = style;
This works for the most part, but I am still seeing some gray around it. Any help would be greatly appreciated.
EDIT
I've added an image with the selected areas that I'd like to have as the same color.
You could do this in XAML:
<ControlTemplate x:Key="HeaderTemplate" TargetType="{x:Type xcdg:ColumnManagerCell}">
<TextBlock Text="{TemplateBinding Content}">
<TextBlock.Style>
<Style TargetType="{x:Type TextBlock}">
<Setter Property="Background" Value="Black" />
<Setter Property="Foreground" Value="Red" />
</Style>
</TextBlock.Style>
</TextBlock>
</ControlTemplate>
<Style TargetType="{x:Type xcdg:ColumnManagerRow}">
<Setter Property="Background" Value="Black"/>
<Setter Property="BorderBrush" Value="Black"/>
</Style>
<Style TargetType="{x:Type xcdg:ColumnManagerCell}">
<Setter Property="Template" Value="{StaticResource HeaderTemplate}"/>
</Style>
