Sizing the content to fit into screen resolution - wpf

hello i have a window(wpf) with labels and text boxes, i want him to fit to the screen resolution as much as possible,
how do i do it

Viewbox is quite useful if you need the content of your window to scale proportionally when you resize the window (for example maximize it). In this minimalistic page
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Viewbox>
<StackPanel>
<TextBlock FontSize="14">Example</TextBlock>
<Border Background="Aqua" Width="100" Height="100"></Border>
</StackPanel>
</Viewbox>
</Window>
you have a TextBlock and a colored Border stacked vertically; if you start this xaml the window will have a size of 300x300, the font of the TextBlock will be 14 in size and the colored border will be 100x100. If you rescale the window you will see both the TextBlock and the Border scale accordingly (so they'll be no more of the size you've specified in the xaml), keeping relative proportions. Viewbox is really useful, in this respect, if you need a window whose internal components layout look always the same independently from the final resolution it will be displayed (what does matter is aspect-ratio, thought). This obviously work with any contents you'll put inside the Viewbox (we had an application with videos and 3D views for example). Note that in Visual Studio 2008 you'll not be able to see the content of the Viewbox in the Designer.
Hope this help.

If you want to scale really everything including font sizes, you could probably apply a scale transform to your content, and bind it's X and Y values to the window's width and height. You would then also need a value converter to convert those to the appropriate scale.

If you want to scale everything to the size of the window just put everything inside a Viewbox control.

Do you mean you want the window to fill the entire screen? The simplest way to do that (without causing further headaches) is to maximise the window.
w.WindowState = WindowState.Maximized;
EDIT:
A scalable window layout requires you to avoid using the XAML editor in Visual Studio! Actually you can do it in the editor, but it is very hard.
Much easier to write the XAML by hand:
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Grid.Column="0" Grid.Row="0">First Name</Label>
<TextBox Grid.Column="1" Grid.Row="0" Name="firstName">Fred</TextBox>
<Label Grid.Column="0" Grid.Row="1">First Name</Label>
<TextBox Grid.Column="1" Grid.Row="1" Name="lastName">Smith</TextBox>
</Grid>
This will size to fit the window, though may look strange, as the rows and columns will by default get half the space each. You can override this so they have a height determined by their contents instead:
<RowDefinition Height="Auto"/>
It can also help to put margins on some controls, to space them out:
<TextBox Grid.Column="1" Grid.Row="1" Margin="6" Name="lastName">Smith</TextBox>

Add WindowState="Maximized" to the Window
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300" WindowState="Maximized" >
</Window>

Why is my window transparent when using AllowsTransparency="True"

I'm attempting to make a translusent popup that covers the entire screen using WPF. The idea is to effectively create the light box style effect that we all see regularly when using assorted webpages.
The application runs full screen (no option to close, minimise, etc) and replaces the windows shell. Because of this the window needs to stretch to cover the entire of the screen.
The desired effect is to have a new window pop up covering the full screen. This window will have a translucent background with some central content that will be completely opaque. Interaction with the central content will be the only way for the user to interact with the application.
The problem that I am facing is the when AllowsTransparency is set to False the Window is not transparent, as you would expect. But when I set AllowsTransparency="True" then the window and all its contents (including the central content) is completely transparent. The new window, while invisible is there and is stopping any interaction with they system.
Has any one else encountered this problem, of windows not being visible at all when AllowsTransparence="true" is set, or even better found a solution or work around for it?
The xaml for the window is:
<Window x:Class="Views.BorderedPopupView"
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" Background="{DynamicResource WindowBackground}" AllowsTransparency="True">
<Window.Resources>
<SolidColorBrush x:Key="TranslusentBrush" Opacity="0.1"/>
<SolidColorBrush x:Key="WindowBackground" Color="Transparent"/>
</Window.Resources>
<Viewbox StretchDirection="Both" Stretch="Fill" Margin="5,0,13,-8" >
<Grid Height="768" Width="1024" Background="{StaticResource TranslusentBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*"></ColumnDefinition>
<ColumnDefinition Width="6*"></ColumnDefinition>
<ColumnDefinition Width="2*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="2*"></RowDefinition>
<RowDefinition Height="6*"></RowDefinition>
<RowDefinition Height="2*"></RowDefinition>
</Grid.RowDefinitions>
<Grid Opacity="1" Grid.Row="1" Grid.Column="1">
<ContentControl x:Name="Popup" Grid.Row="1" Grid.Column="1"/>
</Grid>
</Grid>
</Viewbox>
</Window>
I ran into something similar the other day. For some reason when you set AllowsTransparency="True" you must also specify a Width and a Height for the Window otherwise the whole thing becomes invisible.
I did the same thing you did and also set the WindowState to Maximized but the Window was no where to been seen until I specified a Width and Height.
Your Grid is appearing above your other elements in the z-order, so clicks will be intercepted by it. To turn hit testing off for that Grid, set IsHitTestVisible="false".
If you would not resize your window try set ResizeMode="CanResizeWithGrip" or ResizeMode="NoResize" to window.

Control anchoring in Silverlight

This may be a bit of a silly question, but I'm not sure what else to try, so wanted to ask for some help. My problem is with anchoring controls in Silverlight.
I've got a grid (C1FlexGrid) which sits in a control. The control is used in a page and I simply want the grid size to be determined by the size of the browser window. I want to have a minimum size for it, but allow it to extend both vertically and horizontally as the user expands the browser window. In WinForms (which is what I'm used to) this is easy.
However, in Silverlight it's causing me a headache. Is it possible to get it to behave the way I want?
I've set the control width and height to auto, and specified some design width/height. The user control is then placed onto a page and both the control and page width/height set to auto.
When the grid loads its data, a few hundred rows, it automatically sizes the grid based on the fact in has 200 rows, i.e. becomes very long.
EDIT
Here's some XAML from a simple example:
<navigation:Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation"
xmlns:c1="http://schemas.componentone.com/winfx/2006/xaml" x:Class="Optimize.Client.Presentation.AboutView"
mc:Ignorable="d" d:DesignWidth="640" d:DesignHeight="480"
Title="About"
x:Name="AboutPage"
Style="{StaticResource PageStyle}">
<Grid x:Name="LayoutRoot" Background="White" MinWidth="300" MinHeight="300">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<c1:C1FlexGrid Margin="10" BorderBrush="Red" BorderThickness="1" Width="Auto" Height="Auto" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">
<c1:C1FlexGrid.Columns>
<c1:Column Header="User Group" Width="*" />
</c1:C1FlexGrid.Columns>
</c1:C1FlexGrid>
</Grid>
</navigation:Page>
All I want here is a grid on a page. The page has a minimum size of 300x300. When the browser window expands I want the page to expand with it, and the grid to also expand with it, so that all borders of the grid are 10 from top/bottom/left/right. I've tried specifying * for the width/height of the layout grid, but it's still not working.
Thanks
Auto sizing means "please resize me to my content". That will not limit you to the size of the parent control or browser.
You want Star (*) sizing which basically means "after deducting any fixed or auto columns/rows, please distribute the remaining space among any star-sized columns/rows based on the ratio of star sizes".
You also want your containers to specify HorizontalAlignment="Stretch" and VerticalAlignment="Stretch" so that the amount of space distributed to the star-sized columns/rows can be determined (otherwise it will collapse on itself).
I can be more specific if you can post your XAML.

Why is this button cut off?

In the following XAML code the button text is half missing. I can change the Margin property and it becomes obvious that after 250px the content is hidden. Why is that, and how can I fix it?
<Window x:Class="InnerInterface.InventoryManagement" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="someWindow" Height="500" Width="500">
<DockPanel HorizontalAlignment="Left" Name="dockPanel1" VerticalAlignment="Top">
<Grid DockPanel.Dock="Top">
<Button Name="buttonReturnToMainMenu" Content="someButton" Margin="200,0" Width="125" />
</Grid>
</DockPanel>
</Window>
You have a horizontal margin of 200, and a button width of 125, which means the total width needed to show the control properly is about 525.
You also have HorizontalAlignment=Left" on your DockPanel, which means it will draw the content at whatever width it needs and align it to the left side of the screen instead of stretching it to fill all available space. This means it is blocking out a space of 200 on either side of the control, and drawing the button in the remaining space. If this remaining space is less than 125, the image will be cropped.
If you switch to HorizontalAlignment="Stretch", then it will draw the control first (with margins), then stretch it's size so it fits all available space, so the entire control gets resized rather than cropped.
You might be interested in reading this MSDN article on Alignment, Margins, and Padding in WPF.
Edit
If you want only the Left margin to be 200, then use Margin="200,0,0,0". Using Margin="200,0" means that both the left and the right Margins will be 200.
Not really sure about your exact problem, but maybe this should help:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="500" Width="500">
<DockPanel HorizontalAlignment="Stretch" Name="dockPanel1" VerticalAlignment="Top">
<Grid DockPanel.Dock="Top" >
<Button Name="buttonReturnToMainMenu" Content="someButton" Width="125" />
</Grid>
</DockPanel>
</Window>
The problem is that the button Margin is set as:
Margin="200,0"
It should be set as:
Margin="200,0,0,0"
This eliminates the margin on the right side and allows the whole button to show.

Having trouble getting contents of ListBox to resize with it

I tried the suggestion here regarding Stretching, but it didn't work for me.
I have a TabItem that hosts a UserControl that is essentially just a ListBox with an ItemsPanel. The ItemsPanel forces the ListBox to display its contents horizontally. The contents of the ListBox are databound to an ObservableCollection<StackPanelContents>, which is another UserControl. StackPanelContents itself basically just contains a List of objects with some visual representation (they contain a UIElement for visualization).
In general the code works properly in that it renders all of the data that I have contained in the ObservableCollection, but the problem is that the items don't resize as the window is enlarged or shrunk.
Here's an overview of what the class hierarchy looks like:
And here are the results:
The XAML for the main window just has the TabControl and TabItem:
<Window x:Class="ResizeStackPanelInListBox.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<TabControl>
<TabItem Header="Test" x:Name="MyTabItem">
<!-- contents are set in code behind -->
</TabItem>
</TabControl>
</Window>
The ListBoxContainer XAML that displays the StackPanelContents looks like this:
<UserControl x:Class="ResizeStackPanelInListBox.ListBoxContainer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="Auto" Width="Auto">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
<TextBlock>ListBox with StackPanels as its ListBoxItems:</TextBlock>
<ListBox Grid.Row="1" ItemsSource="{Binding StackPanels}" HorizontalContentAlignment="Stretch">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" Width="Auto" Height="Auto" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
</Grid>
</UserControl>
And the StackPanelContents UserControl looks like this:
<UserControl x:Class="ResizeStackPanelInListBox.StackPanelContents"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="Auto" Width="Auto">
<StackPanel>
<TextBlock Text="StackPanel"></TextBlock>
<StackPanel x:Name="MyStackPanel">
</StackPanel>
</StackPanel>
</UserControl>
Can anyone explain why this isn't resizing automatically, and how I can go about resolving this? Am I going to have to write my own custom panel to deal with this, and use MeasureOverride and Arrange?
The problem is that you're using StackPanels to arrange items in both directions so you're losing any sort of stretching. StackPanel allows its children to stretch only in the direction opposite the Orientation. The other direction will only be given as much space as it needs in order to allow the rest of the items as much space as possible. So for a default Vertical StackPanel anything you put inside will stretch horizontally but squeeze toward the top vertically. Since you have Vertical StackPanels inside a Horizontal StackPanel you're items are getting squeezed both ways.
There are a few options depending on what you want your items to do. Changing to a DockPanel will allow the last item to stretch and fill the space (the vertical one would need to set DockPanel.Dock=Top in the ItemContainerStyle). A Grid with * sized Rows and Columns works well for normal layouts but not in the case of ItemsControls since the Row and Column need to be set for each item (it can be done using ItemsControl.AlternationIndex but it's a pain and fragile). Using a 1 row/column UniformGrid (as in the answer you referenced) will evenly divide the available space and doesn't require any additional settings on the items.
If you need some more complex layout strategy with different items getting different amounts of space or stretching behavior you'll need a custom Panel.

wpf - window to be tight round user control

I've got a user control that I'm loading into a Window dynamically - I wanted to set the Window so that it didn't have a size and then I thought the window to resize accordingly depending on the UserControl. However it dosn't - can anyone assist please?
I've made a very basic example - I've cut out the dynamic bits and just put a UserControl in a Window. What do I need to do to get the window to be tight around the UserControl?
Thanks,
Andy
<UserControl x:Class="WpfApplication1.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Height="300" Width="300" Background="LightBlue">
<Grid>
</Grid>
</UserControl>
<Window x:Class="WpfApplication1.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:WpfApplication1="clr-namespace:WpfApplication1" Title="Window1" >
<Grid>
<WpfApplication1:UserControl1>
</WpfApplication1:UserControl1>
</Grid>
</Window>
Try setting SizeToContent to WidthAndHeight on your Window.
See MSDN Page
Try setting either Width and Height to Auto, or setting SizeToContent = WidthAndHeight.
Once you know the size of the control, you will then have to update the size of the window. I'm unsure of any way to force the window to resize itself automatically unless you have code doing it.
Check this out for all you need to know, plus some, in order to do this.
Not sure if this will help, but I'd start by making the Window :
Height="Auto" Width="Auto"
If this alone doesn't do the trick I would add a Grid Row and Column
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
And then I would set the
<WpfApplication1:UserControl1 Grid.Row="0" Grid.Column="0" />
Not 100% sure if this will work but its worth a try as this is what I'm doing on my side and it works.
