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.

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.

I have the following code in WPF XAML:
<Window x:Class="WPFDemo.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">
<StackPanel>
<Button Content="Hello World" Width="Auto" Height="Auto"></Button>
</StackPanel>
</Window>
I have set the width and height of the Button to "Auto" but still it stretches the complete horizontal width. What am I doing wrong? I do not want to provide a hardcoded values for the width and height!
You are using the wrong kind of container control. The StackPanel does not resize its contents. Try a Grid instead:
<Grid>
<Button Content="Hello" HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
Also, you don't need to set the Width and Height to "Auto", as the default values will enable the Button to stretch to fill its parent container (depending on the container control). Please see the Panels Overview page on MSDN for more help with the differences between the various container controls in WPF.
As Sheridan said, you do not need to set Width and Height to "Auto".
Your problem is that the default alignment of the StackPanel content is "Stretch".
So just set the HorizontalAlignment property of your button to "Left" or "Right".
<Window x:Class="WPFDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<Button Content="Hello World" Width="Auto" Height="Auto"></Button>

I have been trying to dock a dock panel.But couldn't.Generally in windows forms if we dock a panel it will fit correctly. i searched in google which shows only for docking the buttons in dock panel.
<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="350" Width="525">
<Grid>
<DockPanel>
<DockPanel DockPanel.Dock="Left" Background="Azure">
<TextBlock Width="600"></TextBlock>
</DockPanel>
<DockPanel DockPanel.Dock="Right" Background="Black"></DockPanel>
<DockPanel DockPanel.Dock="top" Background="Cornsilk"></DockPanel>
</DockPanel>
</Grid>
The elements you're binding to the right and top are empty ...
So, you get the one you set the width to to the left (600), then the right one takes width = 0, and the last element fills the rest (since the default for LastChildFill is true), hence you see the Cornsilk color filling everything else.
Seems to work :)
You can also set the LastChildFill to false in the dockpanel like this:
<DockPanel LastChildFill="true">
and then you won't even see the Cornsilk, since it's size is zero as well.
I have MyWindow where SizeToContent="WidthAndHeight" in WPF. When MyWindow is bigger than screen I want to activate a ScrollViewer. What is the easiest way to do that?
you need to use a... Scrollviewer.
some code for you:
<Window x:Class="Test.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow"
Name="Window"
SizeToContent="WidthAndHeight">
<ScrollViewer HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
Background="Green">
<Grid Name="MainGrid" Background="red" MinWidth="600" MinHeight="400">
<!--Some Content Here-->
<Label>Foo</Label>
</Grid>
</ScrollViewer>
</Window>
What this code does:
A Window with SizeToContent=WidthAndHeight, as wanted.
A ScrollViewer that stretches with the window
A Grid to put your content (could be a Canvas, or any kind of Panel). This grid as MinWidth and MinHeight set so that what is inside the grid will be able to stretch up but not down. So your content will initially be 600x400 (in this case) but will be able to stretch up. If you try to size it down to 300x200 for instance, you'll get your scrollbars.
this should at least get you started.
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>
In silverlight 2.0. I have some content that i want to scroll vertically and wrap horizontally. In the controls I have a dock panel. The DockPanel's last child, which fills it, is a ScrollViewer
<UserControl x:Class="MyProject.MyControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:WinControls="clr-namespace:Microsoft.Windows.Controls;
assembly=Microsoft.Windows.Controls"
Width="400" Height="300">
<WinControls:DockPanel LastChildFill="True">
...
<ScrollViewer x:Name="MessageScroll" HorizontalScrollBarVisibility="Hidden"
VerticalScrollBarVisibility="Auto" BorderThickness="0" >
<Controls:TextDisplay x:Name="TextDisplay"></Controls:TextDisplay>
</ScrollViewer>
The TextDisplay control XAML looks like this:
<UserControl x:Class="MyProject.TextDisplay"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<TextBlock x:Name="TextDisplayText" TextWrapping="Wrap">
</TextBlock>
</UserControl>
What I want to happen: The TextDisplay should occupy the main area of the control,
with a vertical scrollbar if the height doesn't fit. The messages should wrap when they get too long horizontally.
The scrolling works, but now the messages don't wrap at the right-hand edge. they just cut off. It's not constraining the width, just hiding the HorizontalScrollBar. If I set HorizontalScrollBarVisibility="Auto" I can see them scrolling off to the right. How do i force it to wrap?
Try setting the HorizontalScrollBarVisibility of the ScrollViewer to Disabled (or do not specify a value as Disabled is the default) then the TextDisplay will wrap correctly and the horizontal scroll bar will not be displayed.
