I am working with WPF, and what I want to do is to set opacity and background color of my button but I dont want to affect content inside my button. I tried few ways but unfortunately that did not work.
I found this style and I would like to apply something like that:
This is my numeric keyboard: ( I AM TRYING TO EDIT BTN 7) :
As you can see guys, unfortunately I could not set opacity of my button without affecting the content inside.
Here is my XAML code (focus on btn 7):
<StackPanel Height="50" Orientation="Horizontal" Margin="0,0,0,5">
<Button FontSize="15" FontWeight="Bold" x:Name="btn7" Foreground="#83D744" Click="btn7_Click" BorderBrush="#83D744" BorderThickness="0.5" Content="7" Width="80" RenderTransformOrigin="0.557,0.693" d:LayoutOverrides="HorizontalAlignment" Background="Black" Opacity="0.2" Margin="0,0,5,0" />
<Button FontSize="15" Foreground="Black" FontWeight="Bold" x:Name="btn8" Click="btn8_Click" Content="8" Width="80" Background="#FF50504F" Margin="0,0,5,0"/>
<Button FontSize="15" Foreground="Black" FontWeight="Bold" x:Name="btn9" Click="btn9_Click" Content="9" Width="80" d:LayoutOverrides="HorizontalAlignment" Background="#FF50504F"/>
</StackPanel>
So could anyone help me please how to solve this thing..
Thanks!
add transparency to a brush used for Background
hex code for Black color is #000000
change alpha channel to make it semi-transparent (Background="#50000000") and remove Opacity="0.2"
<Button x:Name="btn7"
FontSize="15" FontWeight="Bold" Foreground="#83D744"
Click="btn7_Click"
BorderBrush="#83D744" BorderThickness="0.5"
Content="7" Width="80" RenderTransformOrigin="0.557,0.693"
d:LayoutOverrides="HorizontalAlignment"
Background="#50000000" Margin="0,0,5,0" />
Make the opacity of the button 0.2 to 1

I have this button and I put some text in it using Content="1", there's a 15px padding around the top and 20px on the left side of the number, however the text appears to go outside of the button when it is resized.
this is what it normally is
and this is what happens when it resizes
if it helps any, here is the XAML code:
<Button x:Name="_btn1" Content="1" HorizontalAlignment="Center" Grid.Row="1" VerticalAlignment="Center" Width="214" FontSize="24" HorizontalContentAlignment="Left" VerticalContentAlignment="Top" Height="182" Margin="10,10,10,10" Background="#33999999" Click="DayClick" Padding="20,15,0,0"/>
Your content is not going outside; some portion of the button is hiding behind the content holder like StackPanel, Grid or whatever you are using.
Here are something you can do -
Use button's auto size instead of hard code size.
<Button x:Name="_btn1"
Content="1"
FontSize="24"
Background="SeaGreen"
Margin="10,10,10,10"
Grid.Row="1"
VerticalAlignment="Center"
HorizontalAlignment="Center"/>
Use ScrollViwer outside of your container.
<ScrollViewer>
<StackPanel>
<Button x:Name="_btn1"
Content="1"
FontSize="24"
Background="SeaGreen"
Width="214"
Height="182"
Padding="20,15,0,0"
Margin="10,10,10,10"
Grid.Row="1"
VerticalAlignment="Center"
HorizontalAlignment="Center"
HorizontalContentAlignment="Left"
VerticalContentAlignment="Top"/>
</StackPanel>
</ScrollViewer>
You can't use ScrollViwer inside of a StackPanel
Use AdaptiveTrigger and change the buttons' properties as you need.
(Read the doc if you are not familiar - AdaptiveTrigger)
I think my title is a bit confusing so let me explain my question in detail.
I have a StackPanel with multiple Grids inside it. It basicly looks like a table with a "Header Grid" and a "Content Grid" below. The StackPanel itself is inside a ScrollViewer.
Whenever the user clicks on the "Header Grid" the corresponding "Content Grid" should be collapsed and visible vice versa.
Here is a short version of my table:
<ScrollViewer Margin="0,0,0,10">
<StackPanel>
<Grid x:Name="Header_Grid1" Height="24" Background="#BF101820" VerticalAlignment="Top" Margin="34,0,0,0" Cursor="Hand" >
<Label Content="Click me to show/hide Content_Grid1" Padding="5,0" VerticalContentAlignment="Center" Margin="5,0,0,0" Grid.ColumnSpan="2" Width="982"/>
</Grid>
<Grid x:Name="Content_Grid1" Height="100" Width="967" HorizontalAlignment="Right" Margin="0,5,0,0" RenderTransformOrigin="0.5,0.5">
<Label Content="some content" Foreground="#FF918F82" Padding="5,0" VerticalContentAlignment="Center" Margin="0,0,719,75"/>
<Label Content="some content" Foreground="#FF918F82" Padding="5,0" VerticalContentAlignment="Center" Margin="0,25,719,50"/>
</Grid>
<Grid x:Name="Header_Grid2" Height="24" Background="#BF101820" Width="1001" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,10,0,0">
<Label Content="Click me to show/hide Content_Grid2" Padding="5,0" VerticalContentAlignment="Center" Margin="5,0,0,0" Grid.ColumnSpan="2" Width="982"/>
</Grid>
<Grid x:Name="Content_Grid2" Height="100" Width="967" HorizontalAlignment="Right" Margin="0,5,0,0" RenderTransformOrigin="0.5,0.5">
<Label Content="some content" Foreground="#FF918F82" Padding="5,0" VerticalContentAlignment="Center" Margin="0,0,719,75"/>
<Label Content="some content" Foreground="#FF918F82" Padding="5,0" VerticalContentAlignment="Center" Margin="0,25,719,50"/>
</Grid>
</StackPanel>
</ScrollViewer >
Lets say the user clicks on "Header_Grid1" the "Content_Grid1" hides with an kinda "flow to the top" animation by reducing its size. Thats no problem at all - the thing is I´d like the "Header_Grid2" aswell as the "Content_Grid2" to flow to the top while the animation of hiding "Content_Grid1" is playing. "Header_Grid2" and "Content_Grid2" should not just pop to the place where "Content_Grid1" has been. It should rather happen in a smooth animation.
Hopefully someone understands what I mean. It´s pretty hard to explain...
Thanks
As far as I am aware you can't animate the collapsed method, but there are various tricks to get around that such as animating the opacity, size, location etc...
In a windows 8.1 project i have the following button with a flyout.
<Button x:Name="FilterCompanyMeetings2" Foreground="White" Content="Company Meetings" Margin="15,58,0,0" Height="40" VerticalAlignment="Top" Style="{StaticResource ButtonStyle2}">
<Button.Flyout>
<Flyout>
<StackPanel Width="406">
<TextBlock Text="Insert the value and tap the Send button:" FontSize="16"
FontWeight="SemiLight" FontFamily="Segoe UI"
Margin="0,0,0,10" />
<TextBox x:Name="ValueTextBox" />
<Button Content="Send" HorizontalAlignment="Right"
FontSize="16" Margin="0,10,0,0" />
</StackPanel>
</Flyout>
</Button.Flyout>
</Button>
Im having a issue when i press the button, the flyout appears as expected but all other buttons change their background to a gray color and some of them change their foreground to black.
I dont use this button for anything at the moment, but when i press it that happens.
Why does it change style of other button on the page?
I am trying to create buttons for a 10-foot GUI using WPF. Each button requires a little more data than just a single text string and an image, maybe 2-3 strings located in different positions and some imagery.
I have tried
<Button Height="52" HorizontalAlignment="Stretch" Name="button1" Width="407">
<Button.Content>
<DockPanel LastChildFill="True" HorizontalAlignment="Stretch">
<TextBlock Name="textBloczk2" Text="ABC" TextAlignment="Left" DockPanel.Dock="Left"/>
<TextBlock Name="textBlxock1" Text="CDE" TextAlignment="Right" DockPanel.Dock="Right"/>
</DockPanel>
</Button.Content>
</Button>
But no matter which inner container I use, the button seems to disregard the layout from the DockPanel and the combined text ends up in the middle of the button. Am I doing something wrong or should I be using a different outer container ?
The problem seems to be that the DockPanel's width is so small that the Right and Left panels are the same width as your TextBlocks.
This seems to work as expected (setting the width of the DockPanel):
<Button Height="52" HorizontalAlignment="Stretch" Name="button1" Width="407">
<Button.Content>
<DockPanel LastChildFill="True" Width="300">
<TextBlock Name="textBloczk1" Text="Left" DockPanel.Dock="Left" />
<TextBlock Name="textBlxock2" Text="Right" DockPanel.Dock="Right" />
<TextBlock Name="textBlxock3" Text="Top" DockPanel.Dock="Top" />
<TextBlock Name="textBlxock4" Text="Bottom" DockPanel.Dock="Bottom" />
</DockPanel>
</Button.Content>
</Button>
Try to add "HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" to your button. This way dockpanel will occupy all space inside the button.
I'm developing a Turing Machine simulator for a class on theory, and I'm trying to change the background color of the input area based upon whether the machine would accept the language (basically, one color over the other depending on if it's valid input).
Since I want to provide a couple example inputs, it needs to be a ComboBox. Since the professor needs to test his own inputs, it must be editable as well. So, here we are.
I've tried setting the ComboBox.Background property both programmatically and using XAML (via the Property editor), and neither work. I have no problem setting ComboBox.Foreground, however.
Here is my XAML:
<Window x:Class="Turing.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Turing Machine Emulator" Height="400" Width="600" Loaded="onload" MinHeight="500" MinWidth="600">
<Grid>
<ComboBox x:Name="drpProblem" HorizontalAlignment="Left" Margin="10,10,0,0" VerticalAlignment="Top" Width="120" SelectionChanged="changeproblem"/>
<Label x:Name="lblDescription" Content="Language Description" Margin="135,7,90,0" VerticalAlignment="Top"/>
<Grid Margin="10,0,10,35" Height="24" VerticalAlignment="Bottom">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="10*"/>
<ColumnDefinition Width="1*"/>
<ColumnDefinition Width="10*"/>
</Grid.ColumnDefinitions>
<Label x:Name="lblLeft" Content="left" HorizontalContentAlignment="Right" VerticalContentAlignment="Center" Padding="0" Margin="0,0,10,0" FontFamily="Consolas"/>
<Label x:Name="lblRight" Content="right" Grid.Column="2" VerticalContentAlignment="Center" Padding="0" Margin="10,0,0,0" FontFamily="Consolas"/>
<Label x:Name="lblCenter" Content="cur" Grid.Column="1" Height="24" Padding="0" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Background="#FFC5FFA4" FontFamily="Consolas" FontSize="16"/>
</Grid>
<Button x:Name="btnIterate" Content="Iterate" Margin="10,0,0,64" Height="20" VerticalAlignment="Bottom" Click="btnIterate_Click" HorizontalAlignment="Left" Width="236"/>
<!-- This one right here -->
<ComboBox x:Name="txtInput" Height="23" Margin="10,0,10,89" Text="Input String" VerticalAlignment="Bottom" FontFamily="Consolas" VerticalContentAlignment="Center" TextBoxBase.TextChanged="cboGetInput" BorderBrush="{x:Null}" Foreground="Black" Background="#FF874343" IsEditable="True" />
<TextBox x:Name="txtMs" Height="20" Margin="251,0,172,64" TextWrapping="Wrap" Text="wait (seconds)" VerticalAlignment="Bottom"/>
<Button x:Name="btnAutoRun" Content="AutoRun" Margin="0,0,10,64" Click="btnAutoRun_Click" Height="20" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="157"/>
<TextBox x:Name="txtTM" Margin="10,38,10,142" TextWrapping="Wrap" Text="Language" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" FontFamily="Consolas" FontSize="14"/>
<Button x:Name="btnLoadLang" Content="Load" Margin="10,0,10,117" Height="20" VerticalAlignment="Bottom" Click="changeproblem"/>
<StatusBar Height="30" VerticalAlignment="Bottom">
<TextBlock x:Name="stTXTName" Text="StateName"/>
<Separator/>
<TextBlock x:Name="stTXTDescription" Text="StateDescription"/>
<Separator/>
<TextBlock x:Name="stTXTTransition" Text="NextTransition"/>
<Separator/>
<TextBlock x:Name="stTXTNext" Text="NextState"/>
</StatusBar>
</Grid>
</Window>
and here is the code I'm using to try to change the colors around:
if (TM.AcceptsString(txtInput.Text))
{
txtInput.Background = Brushes.LightGreen;
txtInput.Foreground = Brushes.LightGreen;
}
else
{
txtInput.Background = Brushes.Pink;
txtInput.Foreground = Brushes.Pink;
}
The foreground changes as expected, but the background color never changes from the default White. Am I doing something wrong? Is there some component control within ComboBox that I need to be setting properties for, as I did with TextBoxBase.TextChanged?
Set the FlatStyle attribute of the ComboBox to FlatStyle.Flat. This resolved a similar issue I experienced when the Win 7 Aero theme is turned on: The backcolor of the ComboBox does not show up in the default FlatStyle setting FlatStyle.Standard.
I had a similar issue and was able to resolve it by auto-generating the template for the ComboBox in Visual Studio 2015 (Right Click ComboBox in Design Window -> Edit Template -> Edit a Copy)
