I am trying to add a picture to my Window in WinUI3 and the image is never rendered. When checking in the live visual tree, the actual size of the image is 0 even though its width and height are set to 200px. Can someone tell me what's wrong with my XAML ?
<Window

Found the bug. I was debugging the package itself and I needed to add the image to the assets found in the package.

Hello everyone，my English is not OK. I'm using google translation.
I'm transplanting scintill to UWP. The ScrollBar is not shown in the above code. I tried using ScrollViewer+CanvasVirtualControl，but it needs to modify scintill's code in EditView .
Thanks.
There are Thumb in the layout of the following figure
I am making an application and I want certain grid rows and columns to be fixed, while others resize to fit the window. My problem is that I cannot do this in Universal Apps.
In WPF, the solution is simple:
<Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Grid.RowDefinitions>
<RowDefinition Height="50" /> <!-- This row is a fixed height -->
<RowDefinition Height="*" MinHeight="200" /> <!-- This row is resizeable, but has a minimum height -->
<RowDefinition Height="100" />
<RowDefinition Height="20" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20" /> <!-- This column has a fixed width -->
<ColumnDefinition Width="*" MinWidth="300" /> <!-- These rows are resizeable, but have minimum widths -->
<ColumnDefinition Width="*" MinWidth="300" />
<ColumnDefinition Width="20" />
</Grid.ColumnDefinitions>
</Grid>
When I try this in UWP, the rows and columns with fixed sizes resize while the others with asterisks stay fixed. I tried putting asterisks on the fixed rows and columns and removing the pre-existing ones. I thought that in UWP it was reversed, however this severely messed up my app and made it worse.
My solution was to try the following in UWP:
<Grid x:Name="pageGrid"
Background="White">
<Grid.RowDefinitions>
<RowDefinition MaxHeight="20"
MinHeight="20"/>
<RowDefinition Height="*"/>
<RowDefinition MaxHeight="20"
MinHeight="20"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition MaxWidth="20"
MinWidth="20"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition MaxWidth="260"
MinWidth="260"/>
<ColumnDefinition MaxWidth="20"
MinWidth="20"/>
</Grid.ColumnDefinitions>
</Grid>
The idea here is to have fixed margins around my controls, at 20 pixels width. Inside these margins there are two boxes: One has a fixed width and resizable height, and the other resizes in both directions.
Despite this, I again experienced the same problem where the margins resize but the 'resizable' boxes do not.
Is there actually a way to have fixed and resizeable rows and columns in a grid using Universal Windows Platform? So far, i have yet to find evidence of this.

This code is intended to have extra rows and columns as margins around the main controls. These should be fixed at 20 pixels. When I run the code the margins stretch and the central boxes stay fixed; this is the opposite of what I intended:
(The black outlined area stays the same size when the window is resized while the margins stretch to fit the window.)
Your main Grid is fixed at 800 x 450 px. If you remove that restriction, the grid will stretch appropriately
Updated code:
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"
MinWidth="800"
MinHeight="450">
<Grid x:Name="pageGrid"

I'm trying to add a title to my xaml page, in the small space above the 4x4 grid, but when i try to add the label, it says content is set more than once.
here is my code:
<Window x:Class="WpfApplicationAssignmentgood.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid Name="mainGrid" Margin="0,56,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
</Grid>
<Label Content="Hello" HorizontalAlignment="Center", VerticalAlignment="Center" FontFamily="Arial Black" FontSize="24" />
</Window>
Your Window can only contain one child. In your case, your Window contains a Grid, and a Label.
Ensure that your Window only has one child, you can achieve this by placing your Label inside a Grid. Something like this:
<Window ... >
<Grid>
<Grid ...>
...
</Grid>
<Label Content="Hello" ... />
</Grid>
</Window>
I'm using TextLineBounds in Windows 8.1 to align text of different font sizes on the baseline, such as
With the XAML looking like:
<Grid x:Name="PageHeader">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="28" />
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="15" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="15" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="1"
VerticalAlignment="Bottom"
TextLineBounds="TrimToBaseline"
FontSize="50"
Text="OOO Big Font" />
<TextBlock Grid.Column="3"
VerticalAlignment="Bottom"
TextLineBounds="TrimToBaseline"
FontSize="26"
Text="OOO SmallerFont" />
<TextBlock Grid.Column="5"
VerticalAlignment="Bottom"
TextLineBounds="TrimToBaseline"
FontSize="20"
Text="OOO Even Smaller Font" />
</Grid>
</Grid>
When I resize the window, at some point (before the minimum size of 500) the descenders are clipped (and I've also seen the bottom pixel or two across entire line get clipped even when there are no descenders - resulting in artifacts like a flattened O).
The display elements do not change on the resize, there's no modification due to visual state, etc.
It seems like a bug, but not sure if there's a workaround (other than to abandon use of TextLineBounds).

I am also using Jeff Wilcox's PhoneThemeManager 1.2 to make my app always load in light theme.
When I have appBar in this screen and the keyboard opens, there is extra margin of about 48 px below the textBox. When the phone theme is black, this shows an ugly black bar above the keyboard and below the textBox. When the phone theme is white, this black color bar is in white color. Here are screenshots to better demonstrate:
However, when I disable the appbar and then open the keyboard, this extra margin below the textBox is not there.
I want to disable this extra margin when keyboard is open just like how it happens in messaging hub where appBar is there, along with auto correct bar of keyboard and still this extra margin isn't there.
The only way (known by now) is to disabling the AppBar when you're typing.
Hi i had this problem too. Setting the Textbox.InputScope to nothing removes the extra bar above the keyboard, other than that I wasn't able to make it disappear, short of removing the AppBar.
