I have a WPF window that hosts a simple layout of a home button, top row of buttons and a video feed
but when I maximise the window. the layout is out of sync with the standard view.
I have tried to remedy some of the layout by setting the image element to stretch "fill" but the top row of buttons don't look uniform also the home button relocates to the center of the screen which doesn't look good
My question I how would I adjust the xaml layout properties to support standard and maximised view?
This is the layout for the window:
<Window x:Class="KinectKickboxingBVversion1.TrainingFrm"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="TrainingFrm" Height="377.612" Width="637.313" Loaded="Window_Loaded">
<Grid>
<StackPanel Orientation="Horizontal" >
<Button x:Name="jabBtn" Background="BlueViolet" Content="Jab" Width="100" Height="50" Click="jabBtn_Click" HorizontalAlignment="Center" VerticalAlignment="Top"/>
<Button x:Name="crossBtn" Background="BlueViolet" Content="Cross" Width="100" Height="50" Click="crossBtn_Click" HorizontalAlignment="Center" VerticalAlignment="Top"/>
<Button x:Name="jabCrossHookBtn" Background="BlueViolet" Content="Jab-Cross-Hook" Width="100" Height="50" Click="jabCrossHookBtn_Click" HorizontalAlignment="Center" VerticalAlignment="Top"/>
<Button x:Name="pKickBtn" Content="Push Kick" Background="BlueViolet" Width="100" Height="50" Click="pKickBtn_Click" HorizontalAlignment=" Center" VerticalAlignment="Top"/>
<Button x:Name="blockBtn" Content="Kick Block" Background="BlueViolet" Width="100" Height="50" Click="blockBtn_Click" HorizontalAlignment=" Center" VerticalAlignment="Top"/>
<Label Content="SCORE: " x:Name="lblScore" Visibility="Collapsed"/>
<TextBlock x:Name="tblkScore" />
</StackPanel>
<Viewbox Grid.Row="1" Stretch="Uniform" HorizontalAlignment="Center">
<Image x:Name="KinectVideo" Width="640" Height="250" Visibility="Visible" Stretch="Fill" />
</Viewbox>
<Button x:Name="homeBtn" Content="" Width="50" Click="homeBtn_Click" Height="35" Margin="272,294,277,10" >
<Button.Background>
<ImageBrush ImageSource="Images/ContentIcon.png" />
</Button.Background>
</Button>
</Grid>
</Window>
Your buttons are all a fixed size. StackPanel just plonks them next to each other, so when your screen size is bigger, you end up with space left over on the right.
Same with your home button. It's being positioned via the absolute margins.
You could make your layout fluid by using 6 grid columns for the top buttons, and removing the margins on the home button and just setting it to HorizontalAlignment="Center" VerticalAlignment="Bottom".
However, this will still result in effectively smaller text on the buttons. If you want the display to always have the same proportions it may be easier for you to simply plonk the whole thing in a ViewBox.
use grid instead of stackpanel and set the column width to "*" and put your buttons in that grid

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 have a listbox with objects but I cannot scroll to the bottom of the page. What is the problem? This is the code that I'm using.
<Grid>
<Image Name="Nietcomment" Source="write.png" Width="70" Margin="350,-850,0,0" Tap="Login_popup" Visibility="Visible"/>
<Image Name="welcomment" Source="write2.png" Width="70" Margin="350,-850,0,0" Tap="Login_popup_remove" Visibility="Collapsed"/>
<ScrollViewer Name="scrollview" VerticalScrollBarVisibility="Visible" Margin="0,0,0,0" Foreground="Black">
<StackPanel>
<TextBlock x:Name="NTitelComment" Text="{Binding}" TextWrapping="Wrap" FontSize="25" Margin="10,0,10,0" Foreground="#FFE5001b"/>
<Line Stretch="Fill" Stroke="Black" X1="0" X2="1" Y1="0" Y2="0" Margin="10,0,10,0"/>
<TextBlock x:Name="tijdComment" Text="{Binding}" Margin="50,0,10,0" Foreground="Black"/>
<Image Height="20" Width="20" Margin="-380,-20,0,0" Source="/PostDateIcon.png"/>
<ListBox Margin="0,0,0,20" Name="lbComments" VerticalAlignment="Top" />
</StackPanel>
</ScrollViewer>
</Grid>
If you put a border around your ScrollViewer, can you see if it goes outside of the screen maybe? Will it help to set a fixed height of the Grid or ScrollViewer?
Keep in mind the phone has built in scroll, so your ScrollViewer maybe doesn't play well with it.
With so much fixed margins, your layout will be impossible to manage, especially when dealing with differents screen resolutions and especially with negative margins.
Anyway, right now, you have two scrollviewers, as your listbox contains one as well.
You should disable the listbox scrollviewer or it will prevent your page to scroll.
Just change your listbox:
<ListBox
Margin="0,0,0,20"
ScrollViewer.VerticalScrollBarVisibility="Disabled"
Name="lbComments"
VerticalAlignment="Top" />
It will disable it's scrollviewer and allow it to scroll with the rest of the page.
I have a basic WPF windows with the markup as specific below:
<Window x:Class="Application.SomeWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="SomeWindow"
Topmost="True" WindowStyle="None" Height="39" Width="400"
ResizeMode="NoResize" ShowInTaskbar="False"
WindowStartupLocation="Manual" Background="Transparent"
Closing="Window_Closing" AllowsTransparency="True" Opacity="0">
<Border Background="CornflowerBlue" BorderBrush="Black" BorderThickness="0,0,0,0" CornerRadius="5,5,5,5" Opacity="0.75">
<Grid>
<!-- Display bar -->
<Image Grid.Row="1" Height="24" Margin="7,7,0,0" Name="img1" Stretch="Fill" VerticalAlignment="Top" Source="/Application;component/Images/dashboard/1.png" HorizontalAlignment="Left" Width="13" />
<Image Height="24" Margin="19,7,47,0" Name="image21" Source="/Application;component/Images/dashboard/2.png" Stretch="Fill" VerticalAlignment="Top" Grid.Row="1" Grid.ColumnSpan="2" />
<!-- Button 1 -->
<Button Style="{DynamicResource NoChromeButton}" Height="27" Margin="0,5,25,0" Name="btn1" Click="btn1_Click" VerticalAlignment="Top" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Right" Width="23" ToolTip="1">
<Image Height="26" HorizontalAlignment="Right" Name="img1" Source="/Application;component/Images/dashboard/3.png" VerticalAlignment="Top" Width="22" Stretch="Fill" />
</Button>
<!-- Button 2 -->
<Button Style="{DynamicResource NoChromeButton}" Height="27" Margin="0,5,5,0" Name="btn2" Click="btn2_Click" VerticalAlignment="Top" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Right" Width="23" ToolTip="2">
<Image Height="26" HorizontalAlignment="Right" Name="img2" Source="/Application;component/Images/dashboard/4.png" VerticalAlignment="Top" Width="22" Stretch="Fill" />
</Button>
</Grid>
</Border>
</Window>
Here is what it looks like now:
What I'd really like to do is make it so that initially looks like this:
Then, once mouseover happens, to fade background opacity in from 0 so it looks like the first image. The problem is that if I set the Border or Grid Background color to Transparent with the goal of fading in on mouseover, then everything inside the Border or Grid is affected as well.
Is there a way to manage the opacities of window and its UI elements seperately? Or perhaps there is a totally different route to take to get this background fade on mouseover? Thanks.
There are two options. Number one is to just move the outer border inside the grid, as the first child (and have the other controls alongside it, not in it). That way it will fade by itself, but still be behind the other controls. You will of course either have to set ColumnSpan/RowSpan, or wrap the entire thing in another Grid.
The second option is to just fade the background, not the entire border:
<Border ...>
<Border.Background>
<SolidColorBrush Color="CornflowerBlue" Opacity="0.5"/>
</Border.Background>
...
try this trick - draw a rectangle or border with dimensions bind to parent or ElementName.
It won't affect rest of elements of tree. Works for me.
<Grid x:Name="abc">
<Border
Width="{Binding ActualWidth, ElementName=abc}"
Height="{Binding ActualHeight, ElementName=abc}"
Background="Blue"
Opacity="0.5"/>
//buttons or inner grid
...
</Grid>
If you don'w want to use ElementName, simply replace Width and Height by
Width="{Binding ActualWidth, Source={RelativeSource Mode=FindAncestor, AncestorType=Grid}}"
Height="{Binding ActualHeight, Source={RelativeSource Mode=FindAncestor, AncestorType=Grid}}"
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 have a MediaElement object in my XAML, which loads my movie just fine. What I want to do is render the play, pause and stop buttons right in the center my MediaElement object, kind of like how if you embed a YouTube video on a web page, you get the big play button in the center of the video. Can I do this in WPF using MediaElement?
In case anyone else ever needs to do this, I figured it out. I simply created a Canvas and stuck the MediaElement and the Button both inside the Canvas. I then used ZIndex to change the ZOrdering so the button was on top. Finally, I centered the button on top of my movie. Here is the XAML:
<StackPanel Orientation="Horizontal" Background="LightGray" DockPanel.Dock="Bottom" Height="100">
<Canvas Width="100">
<Button Canvas.ZIndex="2" Canvas.Left="42" Canvas.Top="35">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Polygon Points="0,0 0,26 17,13" Fill="#80000000" Stroke="White" />
</ControlTemplate>
</Button.Template>
</Button>
<MediaElement Canvas.ZIndex="1" Canvas.Top="0" Canvas.Left="0"
x:Name="mediaElement1" UnloadedBehavior="Manual" LoadedBehavior="Manual" ScrubbingEnabled="True"
Loaded="mediaElement1_Loaded" Width="100" Height="100">
</MediaElement>
</Canvas>
</StackPanel>
Or you need to place mediaElement and Buttons to same Grid and set Canvas.ZIndex to higher number than 0:
<Grid>
<Button VerticalAlignment="Center" HorizontalAlignment="Center" Height="50" Width="100" Canvas.ZIndex="1">Button</Button>
<MediaElement Source="/Assets/ladybug.wmv">
</MediaElement>
</Grid>
(actually you don't need Canvas [works on UWP]):
