I have this very simple ChildWindow:
<Grid x:Name="LayoutRoot" Margin="2">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Button x:Name="CancelButton" Content="Cancel" Click="CancelButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Margin="0,12,0,0" Grid.Row="1" />
<Button x:Name="OKButton" Content="OK" Click="OKButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Margin="0,12,79,0" Grid.Row="1" />
<ScrollViewer Width="378">
<StackPanel>
<TextBlock x:Name="txtFracture" HorizontalAlignment="Left" Margin="10,10,10,10" TextWrapping="Wrap" VerticalAlignment="Top" Width="358"/>
</StackPanel>
</ScrollViewer>
</Grid>
My problem is that the text in the TextBlock is getting clipped on the right side. (I originally didn't have the StackPanel in there - that was just an experiment.) I have added more and more to the Margin.Right, but it doesn't help. The Scroll bar itself isn't stepping on the text, the text just drops a bunch of pixels as it gets to the right of the block. Sometimes, it isn't even whole letters that are getting clipped. See anything?
Also, if I change the HorizontalAlignment from Left to Center, I get the pixel-clipping on both sides of the block.
Also, if I remove the ScrollViewer altogether, the clipping is still there, so it isn't his fault, either.
I notice you have texblock width as constant and you need margin of 10 on all side. In this case ScrollViewer ScrollBar clips your TextBlock.
Possible solution is
1. Remove width on textblock and set alignment stretch.
try this
<ScrollViewer Width="378" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Auto">
<TextBlock x:Name="txtFracture" HorizontalAlignment="Stretch" Margin="10,10,10,10" TextWrapping="Wrap" VerticalAlignment="Stretch"
Text="Testing"/>
</ScrollViewer>
Turns out that this works:
<ScrollViewer Width="378" >
<StackPanel>
<TextBlock x:Name="txtFracture" Margin="10,10,10,10" TextWrapping="Wrap" />
</StackPanel>
</ScrollViewer>
As far as I can tell, the actual culprit was the explicitly set TextBlock Width.

Learning basic concepts of WPF before moving to UWP. Following XAML in my WPF project is showing the windows as below.
I'm trying to display the Rectangle and Button on the right side of the StackPanel and need the Rectangle (not the Button) control to auto fill the StackPanel.
I tried the HorizontalAlignment="Stretch" with no Width attribute but without Width attribute the entire rectangle shrinks to 0 width. Don't want to hard code the width value (if possible) so that window of the app adjust itself depending on the device it's on (screen resolution). But if that scenario is still possible with hard coded width value as well please let me know that approach as well.
Window:
XAML:
Remark: I don't think ListBox is playing any role (related to this post). Only controls inside the ListItemsControl on above ListBox probably need proper adjustment. but I may be wrong.

Two things here:
When you use Stackpanel with horizontal orientation, horizontalalingment="stretch" can't be used. That is because all of the elements are being Stacked with their designed width.
You are specifying a fixed width of 100 for your rectangle. If you do that it will not stretch anymore even if you use stretch for alignment. Also the horizontalalingment="stretch" needs to be placed on the element you are expecting to stretch, not the Panel.
For things like this use DockPanelor a Grid instead.
Read more about WPF panels here:
https://wpf-tutorial.com/panels/introduction-to-wpf-panels/
Here is an example for Grid:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Rectangle x:Name="myRectangle" Fill="#FFF4F4F5" HorizontalAlignment="Stretch" Height="9" Margin="0,0,0,0"
Stroke="Black" VerticalAlignment="Top" RenderTransformOrigin="0.533,0.6" Grid.Row="0"/>
<Button Content="" HorizontalAlignment="Right" Height="10" VerticalAlignment="Top" FontSize="5" FontWeight="Bold" Grid.Column="1"/>
</Grid>
Notice the width="*" attribute means the cell will use all the remaining space. If you have multiple rows/columsn defined with * the space will be divided between them.
Stack Panel acts like a stack of things placed one after another. It can be horizontal or vertical. Unlike Grid you cannot access particular place in a stack panel, every next element will be placed after one another in a sequence.For your requirement a StackPanel is not suitable unless you need to have horizontal scrolling. You should try a DockPanel or Grid instead like
<Grid Height="10">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="auto"/>
</Grid.ColumnDefinitions>
<!--first column of grid-->
<Rectangle Grid.Column="0" x:Name="myRectangle" Fill="#FFF4F4F5" Height="9" Margin="0,0,0,0" Stroke="Black" VerticalAlignment="Top" RenderTransformOrigin="0.533,0.6"/>
<!--second column of grid-->
<Button Grid.Column="1" Content="" HorizontalAlignment="Right" Height="10" VerticalAlignment="Top" FontSize="5" FontWeight="Bold"/>
</Grid>
I am really confused why some of my textboxes and buttons are being cut off, could someone please help me fix this problem? Thanks!!

As you can see the button and the textbox is cut off in the corners.
Thank you for the help I appreciate it.
When you give a Margin value like this Margin="180,10,180,176" then it means that the control has to be placed 180 dip from Left and 10 dip from Top, 180 from Right and 176 from bottom with reference to the parent control. Your controls were clipped because of the high Margin values.
Note: dip - device independent pixels.
It is better to create RowDefinitions for Grid and place controls in separate rows with reasonable margin value as shown below.
<Grid>
<TabControl>
<TabItem Name="tabHome">
<TabItem.Header>
<Label Content="Home"/>
</TabItem.Header>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Button Grid.Row="0" Content="Parse" Height="23" x:Name="btn_parse" Width="75" Margin="10" />
<TextBox Grid.Row="1" IsReadOnly="True" x:Name="txtbox_filepath" Height="25" Width="135" Margin="10" />
<Button Grid.Row="2" Content="Reset" Height="23" x:Name="btn_reset" Width="75" Margin="10"/>
</Grid>
</TabItem>
<TabItem Name="tabConfig">
<TabItem.Header>
<Label Content="Configuration"/>
</TabItem.Header>
<ScrollViewer>
<StackPanel Name="panelConfig">
</StackPanel>
</ScrollViewer>
</TabItem>
</TabControl>
</Grid>
You're explicitly setting a Height and Width for the buttons, but the values you are using are too small.
If you leave them off, the button should display correctly:
<Button Content="Parse" x:Name="btn_parse" Click="buttonParse_Click" Margin="180,10,180,176"/>
<Button Content="Reset" x:Name="btn_reset" Margin="180,122,180,64" Click="buttonReset_Click"/>
Note that you can do a better job of the layout if you design this yourself using a Grid or other container instead of using Margin, as well.
Remove the Height, Width and Margin properties.
Don't use the Visual Studio designer to create WPF UIs.
Take a look at http://wpftutorial.net/LayoutProperties.html
You have used height, Width property along with Margin property. Remove height and width property and it will work fine. Ex.
<Button Content="Parse" x:Name="btn_parse" Click="buttonParse_Click" Margin="180,10,180,176"/>
I have the following XAML which is meant to show an Image and two TextBlocks on top of eachother beside it:
<StackPanel Orientation="Horizontal" >
<Image Source="{Binding CoverArt}" Height="150" />
<StackPanel Orientation="Vertical">
<StackPanel>
<TextBlock FontSize="30" Text="{Binding Title}" TextWrapping="Wrap" />
</StackPanel>
<Grid Width="auto">
<TextBlock FontSize="22" Text="{Binding Summary}" TextWrapping="Wrap" />
</Grid>
</StackPanel>
</StackPanel>
My problem is getting the text to wrap. I've tried using a Grid and assigning the columns' width but it didn't work. Neither did setting the width values to auto. The only thing that works is hard-coding the width, but I do not want that. Thanks.
A Stackpanel will stretch to the size of its content, so it's not what I would use. Use a grid, as explained in the following posts:
TextBlock TextWrapping not wrapping inside StackPanel
Text in StackPanel doesn't wrap (wp7)
TextBlock inside stackpanel does not wrap text
A quick comparison:
Before with stackpanel
After with one grid (You might want to rearrange the elements a bit)
The code for the last segment:
<pre>
<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Ellipse Fill="red" Width="150" Height="150" />
<StackPanel Grid.Column="1" Orientation="Vertical">
<StackPanel>
<TextBlock FontSize="30" Text="basdljhba dnaiks d., kasndca casn oiäc cas lkcnaso ca dxjwöbdq wkjöbdqw dkjwqb " TextWrapping="Wrap" />
</StackPanel>
<Grid Width="auto">
<TextBlock FontSize="22" Text="dewdewdewdewdewewd" TextWrapping="Wrap" />
</Grid>
</StackPanel>
</Grid>
Did you try setting the width of the columns to fractions instead? width="2*" That will give you some boundaries without a pixel set size. Some way or another you need to set a constraint for the container. If you have two columns and no size is set they will get 50% each. 2* will make give that column 2/3 of the total column with, see example below.
I'm trying to layout a set of TextBoxes, vertically, one on top of the other. If there are so many TextBoxes that they cannot fit within the Window height then I want a ScrollBar to become available on the Window. The number of input TextBoxes is variable. There is always a last TextBox with the name output.
If all the TextBoxes can appear within the Window height then I want the last TextBox to stretch to the bottom and fill all the remaining space. In addition, if the output TextBox has a lot of Text then I want this TextBox to make a ScrollBar available.
Here's some pseudo XAML of what I have:
<ScrollViewer>
<Grid>
<TextBox Name="input1" Margin="12, 12, 12, 12" VerticalAlignment="Top" HorizontalAlignment="Left" />
<TextBox Name="input2" Margin="12, 60, 12, 12" VerticalAlignment="Top" HorizontalAlignment="Left" />
<TextBox Name="input3" Margin="12, 108, 12, 12" VerticalAlignment="Top" HorizontalAlignment="Left" />
...
<TextBox Name="inputN" Margin="12, ((N - 1) * 48 + 12), 12, 12" VerticalAlignment="Top" HorizontalAlignment="Left" />
<TextBox Name="ouput" Margin="12, (N * 48 + 12), 12, 12" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
</Grid>
</ScrollViewer>
The problem I have right now is that if the output TextBox has a lot of content then it increases in height and has the Window present a ScrollBar. Instead I want the output TextBox to get the ScrollBar.
I can fix that problem by removing the ScrollViewer that is holding the Grid. However if I do that I get another problem. Because the number of input TextBoxes is variable, if there are so many that not all the TextBoxes can show in the Window, the Window doesn't get a ScrollBar, which I need.
I have tried playing around with putting a MaxHeight on the output TextBox, but if there are few input TextBoxes and a tall Window then I'm apt to not fill all of the remaining vertical space.
It sounds like you need to wrap your Output TextBox in a ScrollViewer and also assure it does stay in the bottom (defining some rows in the Grid or docking it to the bottom of a DockPanel.
EDIT: Do you need something like this?
<Grid x:Name="grd01">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="35" />
</Grid.RowDefinitions>
<ScrollViewer Grid.Row="1">
<TextBox HorizontalAlignment="Stretch" TextWrapping="Wrap" />
</ScrollViewer>
</Grid>
SECOND EDIT:
<Grid x:Name="grd01">
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="35" />
</Grid.RowDefinitions>
<ScrollViewer Grid.Row="0">
<StackPanel>
<TextBox x:Name="input"
HorizontalAlignment="Stretch"
TextWrapping="Wrap" />
</StackPanel>
</ScrollViewer>
<ScrollViewer Grid.Row="1">
<TextBox x:Name="output"
HorizontalAlignment="Stretch"
TextWrapping="Wrap" />
</ScrollViewer>
</Grid>
you can use this tweak on the window loaded event with this code:
EDIT:
i modified it so it's even correct if resizing now
private void Window_Loaded(object sender, RoutedEventArgs e)
{
output.MaxHeight = output.ActualHeight;
output.VerticalAlignment = VerticalAlignment.Top;
output.Height = output.MaxHeight;
}
private void Window_SizeChanged(object sender, SizeChangedEventArgs e)
{
output.MaxHeight = output.MinHeight = output.Height = outGrid.ActualHeight;
}
-
<ScrollViewer Height="Auto">
<DockPanel>
<StackPanel DockPanel.Dock="Top" >
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
<TextBox VerticalAlignment="Top" HorizontalAlignment="Stretch" />
</StackPanel>
<Grid DockPanel.Dock="Bottom" Name="outGrid">
<TextBox Name="output" TextWrapping="Wrap" AcceptsReturn="True" HorizontalAlignment="Stretch" VerticalScrollBarVisibility="Auto" VerticalAlignment="Stretch" />
</Grid>
</DockPanel>
</ScrollViewer>
I have a listview of width set to Auto. When I run the windows app, it opens in normal size(not maximized). But when I maximize the window, the listview's width will be same and the space to its right is empty.
normal size
|_________________________|
Maximized
|_________________________|...........
even though the window is now in full screen occupied.
Please guide me in workin on this.
Thanks

StackPanel, by design, does not care about visual space. It aims to take up the smallest amount of space possible. You can leave the innermost StackPanel that wraps the radio buttons in place, but your outer layout containers should be changed to Grid or, as in my example below, DockPanel:
<Window x:Class="Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="445" Width="515">
<DockPanel Name="spDataFlow" Margin="0,45,0,0" >
<DockPanel x:Name="stkPnlDataFlow" VerticalAlignment="Top">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
</Grid>
<StackPanel Grid.Row="1" Background="Red" Margin="20,15,0,0" Orientation="Horizontal" VerticalAlignment="Center" >
<RadioButton Name="rdbtnUploadData" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="12" Foreground="White" Content="Upload Data" IsEnabled="True" CommandParameter="UploadAll"/>
<RadioButton Name="rdbtnDownloadData" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="12" Foreground="White" Content="Download Data" Margin="20,0" CommandParameter="DownloadAll"/>
<RadioButton Name="rdbtnUploadSelected" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="12" Foreground="White" Content="Update Data" Margin="10,0" CommandParameter="UpdateSelected"/>
</StackPanel>
</DockPanel>
</DockPanel>
</Window>
Well, I believe that by default the ListView control automatically fills all available space so it is very strange that have such an issue. Could you paste your code?
