How can I get an inset drop shadow using WPF XAML - c#

I've tried following a few different answers here on SO on achieving a drop shadow effect on my Textbox, here is the code I have so far:
<Style x:Key="TextBoxRoundedInset" TargetType="{x:Type TextBox}">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="BorderBrush" Value="{StaticResource TextBox.Static.Border}"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="AllowDrop" Value="true"/>
<Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst"/>
<Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
<Setter Property="TextAlignment" Value="Center"/>
<Setter Property="HorizontalContentAlignment" Value="Center"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Border x:Name="border" CornerRadius="3" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True" ClipToBounds="True">
<Border Background="Transparent" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Margin="-2">
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
<Border.Effect>
<DropShadowEffect ShadowDepth="0" BlurRadius="10"/>
</Border.Effect>
</Border>
</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="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="{StaticResource TextBox.Focus.Border}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsInactiveSelectionHighlightEnabled" Value="true"/>
<Condition Property="IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="SelectionBrush" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
</MultiTrigger>
</Style.Triggers>
</Style>
Then to display with the styling I have
<TextBox x:Name="textBox" Background="#263238" Height="40" Margin="0,0,0,50" TextWrapping="Wrap" Width="221" VerticalAlignment="Center" HorizontalAlignment="Center" BorderThickness="0" Style="{DynamicResource TextBoxRoundedInset}" FontSize="25"/>
But I end up with a result that looks like this:
I don't want the text to have a glow to it, instead I basically want the text field to look like its dropped into the background any information on how to correct this would be great thanks

I usually use the BorderThickness Property in combination with the BorderBrush Property to give that 3D effect to make it look as if the field is pressed inside, or even outside by swapping the values of the BorderThickness of both Borders.
This is what I used with your snipped:
<Border x:Name="border" CornerRadius="3" BorderBrush="White" BorderThickness="0,0,2,2" Background="{TemplateBinding Background}" SnapsToDevicePixels="True" ClipToBounds="True">
<Border Background="Transparent" BorderBrush="Black" BorderThickness="2,2,0,0" CornerRadius="2">
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
</Border>
</Border>
The disadvantage is not being able to change the BorderBrush and BorderThickness Property anymore since they have no Binding.
Just change the colors in those two Borders to fit your need, I usually just use Black and White since that combination usually gives the strongest effect.

Old question but I did this a little differently. The effect looks less harsh, depending on chosen BorderBrush and BorderThickness.
<Border Background="Transparent" BorderThickness="2" BorderBrush="Black">
<Border.Effect>
<BlurEffect/>
</Border.Effect>
<ScrollViewer x:Name="PART_ContentHost" Focusable="false" HorizontalScrollBarVisibility="Hidden" VerticalScrollBarVisibility="Hidden"/>
</Border>
The result can look like
this

WPF Cannot make the passwordbox element corners rounded

I am trying to to get my PasswordBox corners rounded to make it look more modern. I have successfully done so with my button and TexBlock. However attempting to do so with my PasswordBox does not yield the same results that I desire.
The xaml code for the PasswordBox looks like this
<PasswordBox
Grid.Column="1"
Grid.Row="5"
x:Name="paswordinput"
Margin="170,0,0,0">
<PasswordBox.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="8"></Setter>
</Style>
</PasswordBox.Resources>
</PasswordBox>
the same code worked for my TextBox and my Button. Any help would greatly be appreciated!
The PasswordBox control clears the Style of the Border so you should set the local value of the CornerRadius property in the template:
<PasswordBox
Grid.Column="1"
Grid.Row="5"
x:Name="paswordinput"
Margin="170,0,0,0">
<PasswordBox.Style>
<Style TargetType="{x:Type PasswordBox}">
<Style.Resources>
<Style TargetType="Border">
<Setter Property="CornerRadius" Value="8" />
</Style>
</Style.Resources>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type PasswordBox}">
<Border x:Name="border" CornerRadius="8" 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="#FF7EB4EA"/>
</Trigger>
<Trigger Property="IsKeyboardFocused" Value="true">
<Setter Property="BorderBrush" TargetName="border" Value="#FF569DE5"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsInactiveSelectionHighlightEnabled" Value="true"/>
<Condition Property="IsSelectionActive" Value="false"/>
</MultiTrigger.Conditions>
<Setter Property="SelectionBrush" Value="{DynamicResource {x:Static SystemColors.InactiveSelectionHighlightBrushKey}}"/>
</MultiTrigger>
</Style.Triggers>
</Style>
</PasswordBox.Style>
</PasswordBox>
Hope this blog post will help - https://www.kailashsblogs.com/2017/01/round-corner-passwordbox-in-wpf.html
Use the below code -
<PasswordBox Margin="10" Height="50" Width="200">
<PasswordBox.Template>
<ControlTemplate TargetType="PasswordBox">
<Border CornerRadius="10" BorderBrush="Gray" BorderThickness="1" />
</ControlTemplate>
</PasswordBox.Template>
</PasswordBox>
You could also try to use the following code to set rounded corners for Password. For more details, please refer to here.
<PasswordBox x:Name="paswordinput" Width="100" Height="50">
<PasswordBox.Resources>
<Style TargetType="PasswordBox">
<Setter Property="Template" >
<Setter.Value>
<ControlTemplate>
<Border CornerRadius="10" BorderBrush="Gray" BorderThickness="2" />
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</PasswordBox.Resources>
</PasswordBox>

How can I add a tab control on to the window title bar

I want to add the tab control header (or styled list box) to the windows title bar like this:
New window title bar
I plan to edit the window template to achieve this. But I don't know where to add. Here is the window template I edit in Blend:
<ControlTemplate x:Key="WindowTemplateKey" TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<Grid>
<AdornerDecorator>
<ContentPresenter/>
</AdornerDecorator>
<ResizeGrip x:Name="WindowResizeGrip" HorizontalAlignment="Right" IsTabStop="false" Visibility="Collapsed" VerticalAlignment="Bottom"/>
</Grid>
</Border>
<ControlTemplate.Triggers>
<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="ResizeMode" Value="CanResizeWithGrip"/>
<Condition Property="WindowState" Value="Normal"/>
</MultiTrigger.Conditions>
<Setter Property="Visibility" TargetName="WindowResizeGrip" Value="Visible"/>
</MultiTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
<Style x:Key="WindowStyle1" TargetType="{x:Type Window}">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}"/>
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<AdornerDecorator>
<ContentPresenter/>
</AdornerDecorator>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="ResizeMode" Value="CanResizeWithGrip">
<Setter Property="Template" Value="{StaticResource WindowTemplateKey}"/>
</Trigger>
</Style.Triggers>
</Style>
It turns out that if I don't want to handle the buttons and dragging myself, I have to use a third party control(such as Actiprosoftware). It handles everything for me, and at the same time, provides a more extendable template.

Display of combobox should be empty

I've a simple combobox:
<StackPanel>
<ComboBox>
<ComboBoxItem>ComboBox Item #1</ComboBoxItem>
<ComboBoxItem>ComboBox Item #2</ComboBoxItem>
<ComboBoxItem>ComboBox Item #3</ComboBoxItem>
</ComboBox>
</StackPanel>
I don't know the name of the element, so I marked it with a red circle. I don't want that the selected item is displayed in this circle. It should be empty even if I select an item because I have a comboBox.Background image and that looks terrible. How can I do that?
The part you want to hide is actually called SelectionBoxItem. I've tried using Reflection to get the private static field SelectionBoxItemTemplatePropertyKey so that we can use SetValue method to change the SelectionBoxItemTemplate (which is publicly read-only). However not sure why it did not work (there's nothing changing).
Using Blend for Visual Studio, you will see that the part you need to remove here is the ContentPresenter inside the MainGrid (the root visual of the ComboBox's ControlTemplate). The default style of a ComboBox is fairly complicated. So you should copy all the template into a file (to use in your project) and delete the ContentPresenter to achieve what you want. That way all the ComboBoxes using that same template will have the effect you want.
In case you just want to empty the SelectionBoxItem of some specific comboboxes and copying the default template is something overkill, you can use the following code to remove the ContentPresenter (hence empty the SelectionBoxItem):
//be sure you run this code when the Window has already been loaded.
var grid = yourComboBox.Template.FindName("MainGrid", yourComboBox) as Grid;
grid.Children.Remove(grid.Children.OfType<ContentPresenter>().First());
Here is the whole default ComboBox's Template:

You can see that it's very long. That's why if you target just some specific ComboBoxes, using the code above might be better (although it involves some codebehind).

Show CheckBox-Border on IsChecked

I have the following xaml-code to set a border on a checkbox if the checkbox is checked.
<StackPanel Orientation="Vertical">
<StackPanel.Resources>
<Style TargetType="{x:Type CheckBox}">
<Setter Property="Margin" Value="2"/>
<Style.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="BorderBrush" Value="Lime"/>
<Setter Property="BorderThickness" Value="1"/>
</Trigger>
</Style.Triggers>
</Style>
</StackPanel.Resources>
<CheckBox Content="Use Method 1" />
<CheckBox Content="Use Method 2" />
<CheckBox Content="Use Method 3" />
</StackPanel>
Unfortunately this doesn't work. If I check a CheckBox, nothing happens to the border.
What is wrong with this xaml-code?
You'd need a custom check box template. See below the Aero default style with the modifications that you need:
<SolidColorBrush x:Key="CheckBoxFillNormal" Color="#F4F4F4"/>
<SolidColorBrush x:Key="CheckBoxStroke" Color="#8E8F8F"/>
<Style x:Key="EmptyCheckBoxFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="1" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style x:Key="CheckRadioFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="14,0,0,0" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="{x:Type CheckBox}">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
<Setter Property="Background" Value="{StaticResource CheckBoxFillNormal}"/>
<Setter Property="BorderBrush" Value="{StaticResource CheckBoxStroke}"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="FocusVisualStyle" Value="{StaticResource EmptyCheckBoxFocusVisual}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<BulletDecorator Background="Transparent" SnapsToDevicePixels="true">
<BulletDecorator.Bullet>
<Microsoft_Windows_Themes:BulletChrome BorderBrush="{TemplateBinding BorderBrush}" Background="{TemplateBinding Background}" IsChecked="{TemplateBinding IsChecked}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}"/>
</BulletDecorator.Bullet>
<Border x:Name="ContentBorder" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" BorderThickness="{TemplateBinding BorderThickness}">
<ContentPresenter RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/>
</Border>
</BulletDecorator>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="BorderBrush" TargetName="ContentBorder" Value="Lime"/>
</Trigger>
<Trigger Property="HasContent" Value="true">
<Setter Property="FocusVisualStyle" Value="{StaticResource CheckRadioFocusVisual}"/>
<Setter Property="Padding" Value="4,0,0,0"/>
</Trigger>
<Trigger Property="IsEnabled" Value="false">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
You can add a setter to change border brush of BulletChrome when check box is checked (add a name for bullet chrome and duplicate the setter in trigger for IsChecked, just change the name in the new setter)
EDIT:
Oh, and you'd need this xmlns definition:
xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero"
(of course you'd need a reference to PresentationFramework.Aero assembly)

Why are setters for Backgroud and BorderBrush not working(ItemContainerStyle)? I had to hide selection using redefinition for system Brushes, but its wrong way:
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="#00000000"/>
How could I set BorderBrush for ItemBorder (on mouseOver event)?
How could I set BorderBrush for ItemBorder(only for selected Items)?
What shall I do to change default selection style?
I'd found answer by myself.
To set style for ItemBorder I had to create few DataTriggers and put them into DataTemplate:
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListViewItem}},Path=IsSelected}" Value="True">
<Setter TargetName="ItemBorder" Property="BorderBrush" Value="Lime"/>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type ListViewItem}}, Path=IsMouseOver}" Value="True">
<Setter TargetName="ItemBorder" Property="BorderBrush" Value="Orange"/>
</DataTrigger>
</DataTemplate.Triggers>
About question 1 and 4 I still haven't answer...(If I won't count way to change default system brushes)
