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.

Following XAML in this Microsoft tutorial is showing too much gap between the top edge of the parent window and the UWP user control. Question: How can we make the user control align to the top edge of parent window? Remark: The VerticalAlignment="Top" in the StackPanel below does not help. This question is something similar to this post but in a different context.
<UserControl
x:Class="ClassLibUWP_inside_WPF.MyUserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:ClassLibUWP_inside_WPF"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:winui="using:Microsoft.UI.Xaml.Controls"
mc:Ignorable="d"
d:DesignWidth="400" Height="329">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="211*"/>
<ColumnDefinition Width="189*"/>
</Grid.ColumnDefinitions>
<StackPanel Background="LightCoral" Grid.ColumnSpan="2">
<TextBlock>This is a simple custom UWP control</TextBlock>
<Rectangle Fill="Blue" Height="93" Width="100"/>
<TextBlock Text="{x:Bind XamlIslandMessage}" FontSize="50"></TextBlock>
<winui:RatingControl Height="32" />
</StackPanel>
</Grid>
</UserControl>
When you run the app built in the above tutorial, you get the following screen showing the above UWP user control:
I would instead like to display it as follows [notice about no gap between window title and the red stack panel]:
The UserControl has a fixed height that is smaller than the height of the window and thus is vertically centered in the window. Setting VerticalAlignment="Top" on the WindowsXamlHost should give what you want.
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.
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>
I have been trying hours to create a page (Axml) in expression blend that stays in the center of the browser yet equally reduces the white space on either side when the browser window is resized. And example is this site or most decent site on the net.
Love a code example or link. Thanks
After posting this question I immediately worked it out. Ends up being really simple in Silverlight. I was making it hard for myself.
Makte your grid the same size as your layout grid and remove width and height properties for the User Control.
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="SilverlightApplication2.Page"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"
>
<Grid x:Name="LayoutRoot" Background="White" Width="597.5" Height="532">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid HorizontalAlignment="Left" VerticalAlignment="Bottom" Height="509" Margin="8.5,0,0,23" Width="579">
<Rectangle Height="65" Margin="0,8,0,0" VerticalAlignment="Top" Fill="#FFD64141" Stroke="#FF000000" HorizontalAlignment="Stretch"/>
</Grid>
</Grid>
</UserControl>
Lets say i have a listbox with many items so that a vertical scroll comes up, but i have hidden the scroll bar with
ScrollViewer.VerticalScrollBarVisibility="Hidden"
Is there any way i can add a button that would scroll down for me? iv tryed to add
Command="ScrollBar.LineDownCommand"
to a button but that didnt have any effect.
You need to tell WPF where to start looking for the command handler. Without telling it, it will start looking from the Button and not find anything that handles the LineDownCommand. Unfortunately, setting it to the ListBox will not suffice because the ScrollViewer is inside the ListBox as part of its template, so WPF still won't find it.
Setting it to one of the ListBoxItems is naff, but works:
<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">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<ListBox x:Name="_listBox" ScrollViewer.VerticalScrollBarVisibility="Hidden">
<ListBoxItem x:Name="_listBoxItem">One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
<ListBoxItem>Three</ListBoxItem>
<ListBoxItem>One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
<ListBoxItem>Three</ListBoxItem>
<ListBoxItem>One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
<ListBoxItem>Three</ListBoxItem>
<ListBoxItem>One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
<ListBoxItem>Three</ListBoxItem>
</ListBox>
<Button Grid.Row="1" Command="ScrollBar.LineDownCommand" CommandTarget="{Binding ElementName=_listBoxItem}">Scroll Down</Button>
</Grid>
</Window>
A better way to do this would be to either re-template the ListBox and stick the Button inside the template, or to wire up the CommandTarget in the code-behind.
I had an app where I wanted to manually control the scrolling of a ScrollViewer. Basically, I got a reference to the ScrollViewer and then used the ScrollToHorizontalOffset() method to control the scrolling. Below are the blog posts where I explain the process I used:
