Show/Hide Left and Right Border in WPF RichTextBox codebehind? - c#

I want to hide/show WPF RichTextBox left border sometimes in code behind and also for right border sometimes.
Can this be achieved?
I've already tried in XAML like this borderthickness ="3,3,0,3". It hides my right side, now I need to show that right side border and also hide my right side border.
How do I do that?

The above one is my XAML.
txtAppendValue.BorderThickness=new Thickness("0,3,0,3");
But its not working.

You can do the same thing from code like this:
myRichTextBox.BorderThickness = new Thickness(3,3,0,3);
Then if all borders need to have same thickness, you can use only one number:
myRichTextBox.BorderThickness = new Thickness(3);
Edit:
Since you are using style, you can define multiple styles and then switch between them:
<Style x:Key="MyStyleNoBorders" BasedOn="{x:Null}" TargetType="{x:Type RichTextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RichTextBox}">
<Border x:Name="bg" BorderBrush="Yellow" BorderThickness="0,3,0,3" Background="{TemplateBinding Background}">
<ScrollViewer x:Name="PART_ContentHost" IsDeferredScrollingEnabled="True" CanContentScroll="False" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="MyStyleBothBorders" BasedOn="{x:Null}" TargetType="{x:Type RichTextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type RichTextBox}">
<Border x:Name="bg" BorderBrush="Yellow" BorderThickness="3" Background="{TemplateBinding Background}">
<ScrollViewer x:Name="PART_ContentHost" IsDeferredScrollingEnabled="True" CanContentScroll="False" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Make sure your RichTextBox is not too wide to fit the screen, or you will not be able to see the borders. Then in code just use a call to change styles:
txtAppendValue.Style = FindResource("MyStyleNoBorders") as Style;
and
txtAppendValue.Style = FindResource("MyStyleBothBorders") as Style;

I'm kind of new to WPF and I'm not really sure how the whole thing works. I have three buttons below, which I would like to be individually coloured. I also want them to be transparent and have grey text when they are disabled.
I want them to retain the Background colour property assigned in MainWindow.xaml when they are enabled and be transparent when disabled.
I'm not sure how I would go about this. Does it involve templates, styles, binding converters? Any help would be greatly appreciated.
MainWindow.xaml
<Button Grid.Column="0" Content="Suspend" Style="{StaticResource BubbleButton}" IsEnabled="True" Background="Blue"/>
<Button Grid.Column="1" Content="Training Mode" Style="{StaticResource BubbleButton}" IsEnabled="True" Background="Orange"/>
<Button Grid.Column="2" Content="Exit Program" Style="{StaticResource BubbleButton}" Background="Red"/>
App.xaml
<Style x:Key="BubbleButton" TargetType="{x:Type Button}">
<!-- Triggers -->
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Trigger.Setters>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Foreground" Value="Gray"/>
</Trigger.Setters>
</Trigger>
</Style.Triggers>
<!-- Style -->
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border CornerRadius="10" Background="{TemplateBinding Background}" Name="Button" Margin="10,5,10,5">
<Grid>
<Border BorderThickness="1,0,1,1" BorderBrush="Black" CornerRadius="{Binding ElementName=Button, Path=CornerRadius}">
<Border.Effect>
<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>
</Border>
<Border BorderThickness="0,1,0,0" BorderBrush="White" Margin="2" Opacity="0.7" CornerRadius="{Binding ElementName=Button, Path=CornerRadius}">

<BlurEffect Radius="2" KernelType="Gaussian"/>
</Border.Effect>

</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Foreground" Value="Gray" />
<Setter Property="FontSize" Value="20" />
</Style>
Enabled:
Disabled:

using ControlTemplate.Triggers and adding TargetName should make it work. do the same for TextBlock and Foreground (from what I see, the Setter in Style, not in Trigger should be White).
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter TargetName="Button" Property="Background" Value="Transparent"/>
</Trigger>
</ControlTemplate.Triggers>

I would put a TextBlock inside the header of my TabItem as I have the problem concerning the missing underscore. I changed my style as follows:
<Style x:Key="TabItemDistintaStyle" TargetType="{x:Type TabItem}">
<Setter Property="FocusVisualStyle" Value="{StaticResource TabItemFocusVisual}"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="Padding" Value="6,1,6,1"/>
<Setter Property="BorderBrush" Value="{StaticResource TabControlNormalBorderBrush}"/>
<Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="VerticalContentAlignment" Value="Stretch"/>
<Setter Property="HeaderTemplate">
<Setter.Value>
<DataTemplate>
<TextBlock />
</DataTemplate>
</Setter.Value>
</Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid SnapsToDevicePixels="true">
<Border x:Name="Bd" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="1,1,1,0" Padding="{TemplateBinding Padding}" CornerRadius="6,210,0,0">
<DockPanel>
<ContentPresenter x:Name="Content" DockPanel.Dock="Left" HorizontalAlignment="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" VerticalAlignment="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" ContentSource="Header" RecognizesAccessKey="True"/>
<Button x:Name="cmdClose" DockPanel.Dock="Right"
Command="ApplicationCommands.Close"
Margin="7,0,3,0" Style="{DynamicResource ButtonDistintaCloseStyle}" RenderTransformOrigin="0.5,0.5">
<Button.RenderTransform>
<TransformGroup>
<ScaleTransform/>
<SkewTransform/>
<RotateTransform/>
<TranslateTransform/>
</TransformGroup>
</Button.RenderTransform>
</Button>
</DockPanel>
</Border>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But it does not work, as the first underscore is still missing. What's wrong?

You need bind (set) your TextBlock's Text with TabItem's "Header" property,
i think this sample helps you:

As an experiment, I've been trying to do it on the button "Probleme DEI", using Click="NavigareProbleme".
After I double click on the button, my app looks like this:
My goal is to edit that white bar and its buttons however I want, but I don't know how to do it (and I didn't find anything useful on Google), and move it at the top, above the other buttons.
Also, is there any way to make it always be there? (not only after I double click on "Probleme DEI")
Thanks.

I don't recommend to use a Frame. Instead implement a simple custom page/view navigation using data templates. You can follow this examples, if you are interested: C# WPF Page Navigation Class, How do I toggle between pages in a WPF application?.
Do not wrap each control you want to display.
Using a Viewbox to wrap a Button does not make sense. A Button inside a Grid will always stretch to occupy all available space by default. Use a Viewbox to stretch and scale elements that don't have their own resize behavior implemented and require on absolute layout properties, like Path. I doubt that you really want you buttons to stretch freely as this would look very odd.
Wrapping the lonely Frame into a DockPanel also does not make any sense. A DockPanel is a container, that arranges it's child elements relative to each other. It only makes sense to use it with more than a single child. Just add the Frame directly to the Grid. Every redundant Panel and UIElement will cost a unnecessary performance penalty as they have to be measured, arranged and maybe rendered individually (recursively).
Create a style for a control (WPF .NET) - Do not copy and paste styles to reuse them. Define a single Style, assign it a x:Key and add it to a ResourceDictionary e.g, App.xaml. Then reference it using the StaticResource markup (or define the Style as implicit to make it apply to all buttons implicitly):
App.xaml
<ResourceDictionary>
<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Background" Value="#00000f"/>
<Setter Property="Foreground" Value="#77dff1"/>
...
</Style>
</ResourceDictionary>
Then reference it using StaticResource and the defined key:
<Button Style="{StaticResource ButtonStyle}" />
To customize the navigation bar of the Frame you would have to override the default template. You can visit Frame Styles and Templates to find an example of the original Frame style.
Alternatively hide the original navigation bar (by setting Frame.NavigationUIVisibility) and implement a custom one and use the frame's NavigationService to navigate between its content.
Moving the navigation bar without moving the Frame is not possible. Taking a look at the default template will show you that it is part of the Frame control. You can only move the buttons into a the Page, to make them part of the frame's content.
At this point I have to recommend to implement a custom navigation logic again. It will give you all the flexibility to layout your view you want, as navigation buttons and the actual content host are not part of the same template.
Or hide the original navigation UI and implement your own and locate it where ever you want.

<Setter Property="Foreground" Value="#318EE4"></Setter>
<Setter TargetName="textBlock" Property="TextBlock.TextDecorations" Value="Underline">
<!--That Text decoration part doesnt work--></Setter>

I apply this style to my "usercontrol" (which is actually a button):
<Button x:Name="btn" x:Class="MyStock.MyButton"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d" Height="45" Width="183" Style="{DynamicResource RoundedBtn}" />
When I generate the project, the "MyButton" appears in my custom controls. But if I drag it on my form and test it, the Text Underline doesnt work.
But If i put a normal button on my form and then apply the RoundedBtn style, it works, why ?
By the way, what I am trying to achieve is to have a button that looks like the left menu buttons on this page

Use TargetName in the Setter:
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True" >
<Setter TargetName="textBlock" Property="TextBlock.TextDecorations" Value="Underline" />
</Trigger>
</ControlTemplate.Triggers>
The whole style looks like this (I remove irrelevant part for readability)
<Style x:Key="RoundedBtn" TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="button">
<Grid>
<Border>
<TextBlock x:Name="textBlock" Margin="-1" TextWrapping="Wrap" Text="ABC"
FontSize="13" TextDecorations="{x:Null}">
</TextBlock>
</Border>
</Grid>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True" >
<Setter TargetName="textBlock" Property="TextBlock.TextDecorations" Value="Underline" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

In my WPF application I want to to change borderbrush color for a TextBox when mouse enter, but it does not change color to the one I want, but it change to sky blue (I guess it is standard color).
Here is my XAML code:

I had the same issue on Windows 8, and the only way I was able to fix this issue (which appears to be a bug in WPF) was with a ControlTemplate. This is the standard control template for a TextBox as coughed up by Blend. I changed the BorderBrush colors, added it to my global TextBox style, and it works great. There may be a better solution out there, but this is what works for me.
<Style TargetType="{x:Type TextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ScrollViewer x:Name="PART_ContentHost" Focusable="False" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Red"/>
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="True">
<Setter Property="BorderBrush" TargetName="border" Value="Orange"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
