I have a TextBlock in a Grid with its Padding attribute set to 5. Sometimes the last character is cut off, depending on what string the Text property is set to.
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="SomeClass">
<ScrollViewer Padding="5" VerticalScrollBarVisibility="Auto">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Label
Grid.Row="0" Grid.Column="0"
Content="SomeLabel"
HorizontalAlignment="Right"
HorizontalContentAlignment="Right"
VerticalAlignment="Center" />
<TextBlock
Grid.Row="0" Grid.Column="1"
HorizontalAlignment="Left"
Padding="5"
Text="0x0F"
TextWrapping="Wrap"
VerticalAlignment="Top" />
</Grid>
</ScrollViewer>
</UserControl>
When the Text is set to 0x0F the F is not visible. When it is set to 0xAB the string displays just fine. Setting the Padding to 0 also makes the string display just fine.
What you describe is obviously a layout bug in WPF (probably in the TextBlock). Whether or not the last letter is wrapped (and cut off) seems to depends on the actual width of the string and the size of the last letter in respect to the size of the padding.
I suggest you report the bug here.
To work around this issue you can use the following code (just put a border around you textblock and set the padding there instead):
<Border Padding="5" Grid.Row="0" Grid.Column="1">
<TextBlock HorizontalAlignment="Left"
Text="0x0F" TextWrapping="Wrap"
VerticalAlignment="Top" />
</Border>
Make the column of the grid that contains textblock auto size like this
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<TextBlock Grid.COlumn="0" Text="{Binding Path=SomeViewModelProperty}" />
</Grid>
If you set the height on the TextBlock to 100, does the F then get wrapped?
Just increase the Height of the ComboBoxItem , it should solve the problem.

When I put a Textbox in a grid column like below
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" MinWidth="115"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="hello"/>
<TextBox Grid.Column="1" />
<Button Grid.Column="2" Content="push me"/>
</Grid>
</StackPanel>
I get proper result, i.e. textbox width is get from parent grid
But when I type a long text, the textbox starts exceeding its column and it stops extending after several extra letters
To .Net 4.6.2, I get same result but changing to .Net 4.7.2 the problem is solved i.e. the textbox width is not changing.
My software is compiled .Net 4.0, is there a solution to solve this for lower .net than 4.7.2?
Tried Pavel's first idea: removing stackpanel and adding another grid row in, still not working in .net 4.6.2
Tried Pavel's second idea: making the width of first column "Auto" instead of "1*". This works, the textbox doesn't extend (.net 4.6.2), however I really wanted the first and second column be responsive to resize.
You can solve this be removing the StackPanel and adding RowDefinition to Grid. You can also set TextWrapping="Wrap" for TextBox for wrapping a long text
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="3*"/>
<ColumnDefinition Width="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="0" Text="hello" MinWidth="115"/>
<TextBox Grid.Column="1" TextWrapping="Wrap"/>
<Button Grid.Column="2" Content="push me"/>
</Grid>
StackPanel Y dimension is constrained to content, it will be automatically expanded to its content, more details can be found at panels overview
To me this is a bug that Textbox text size can change its parent width (grid width). This is happening in VS2019 .Net 4->4.6.2 but not in and after .Net 4.7.2.
For anybody faces this problem, I found below workaround by defining an invisible grid which contains textblocks. I get the widths of columns and give them to controls placed in a StackPanel.
<some container>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" MinWidth="115"/>
<ColumnDefinition Width="3*" />
<ColumnDefinition MinWidth="90"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="0"/>
</Grid.RowDefinitions>
<TextBlock x:Name="C0" Grid.Column="0" />
<TextBlock x:Name="C1" Grid.Column="1" Margin="5"/>
<TextBlock x:Name="C2" Grid.Column="2" />
</Grid>
<StackPanel Orientation="Horizontal">
<TextBlock Width="{Binding ElementName=C0, Path=ActualWidth }" Text="hello" />
<TextBox Width="{Binding ElementName=C1, Path=ActualWidth }" Margin="5" />
<Button Width="{Binding ElementName=C2, Path=ActualWidth }" Content="push me"/>
</StackPanel>
</some container>
The margin should be the same for column in grid and control in StackPanel (see second column).
I do not understand if it's a bug that I'm causing some with wrong setting or simply a problem of WPF.
I'm trying to see all content of a GroupBox and I'm using the Viewbox as some label without viewBox for a certain resolution are not visible.
Everything works fine, but it seems there is something wrong with the rendering.
As seen from the image:
by setting this in viewBox:
<Viewbox Stretch = "Fill" Grid.Column = "0" Grid.Row = "0" StretchDirection = "Both">
I can see all content but as you can see the labels are blurred and seem to spread so forced, I do not like.
In the other groupbox I tried to set this:
<Viewbox Stretch="Uniform" Grid.Column="1" Grid.Row="0" StretchDirection="Both">
and I get a nicer effect already at the level of rendering:
the problem is that they remain of the white bands on the right and left (if obviously imposed the minimum resolution reached by the software) and this for me is not nice because I do not use all the UI application.
For those wishing to take a quick look at the complete XAML:
<Viewbox Stretch="Uniform" Grid.Column="1" Grid.Row="0" StretchDirection="Both">
<GroupBox x:Name="Ospite_Analisi" Header="Ospite">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid Grid.Column="0" Grid.Row="0">
<Label>Inserire scudetto</Label>
</Grid>
<Grid Grid.Column="1" Grid.Row="0">
<StackPanel Orientation="Vertical">
<Label>Nome Squadra</Label>
<Label>Nazione</Label>
<Label>Campionato</Label>
</StackPanel>
</Grid>
<Grid Grid.Column="2" Grid.Row="0" Grid.RowSpan="2">
<Label>Inserire controllo forma</Label>
</Grid>
<StackPanel Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="3" Orientation="Horizontal" HorizontalAlignment="Center">
<Label>Vittorie casa</Label>
<Label>Vittorie fuori</Label>
</StackPanel>
<Grid Grid.Column="0" Grid.Row="2" Grid.ColumnSpan="3">
<DataGrid>
...
</DataGrid>
</Grid>
</Grid>
</GroupBox>
</Viewbox>
What I want to achieve is this:
-Fix Both GroupBox in maximum width (the minimum resolution) in viewBox without losing quality and without making it seem forced rendering. How can I achieve this?
I'm trying to add a border to some controls in XAML - the problem is, whenever I apply wrapping a certain element it wraps the whole window, probably on the first grid element?
This also happens when I try to use it around the WebBrowser. Any suggestions?

I would recommend that you do NOT continue to use the Visual Studio Designer as you have been. It does a very poor job of creating the XAML that we actually want. For example, your UI elements have all got an exact Margin set on them (thanks to the VS Designer I imagine) and this can make things awkward for you later on.
WPF was really designed to enable developer to use resizable controls so that the UI can resize itself when the user resizes the application. Different Panels provide different sizing abilities to their child controls and you can find out more about that from the Panels Overview page on MSDN. However, back to your question regarding the Grid class.
Because you have used the Visual Studio Designer, your controls have not ended up in the Grid cells that you wanted, instead just being placed 'on top of', or 'in front of' them. In order to place a control into a particular Grid cell, you need to set the Grid.Row and/or Grid.Column Attached Properties. See this example taken from the last linked page from MSDN:
<Grid VerticalAlignment="Top" HorizontalAlignment="Left" ShowGridLines="True" Width="250" Height="100">
<Grid.ColumnDefinitions>
<ColumnDefinition />
<ColumnDefinition />
<ColumnDefinition />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition />
<RowDefinition />
<RowDefinition />
</Grid.RowDefinitions>
<TextBlock FontSize="20" FontWeight="Bold" Grid.ColumnSpan="3" Grid.Row="0">2005 Products Shipped</TextBlock>

<TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="1">Quarter 2</TextBlock>
<TextBlock FontSize="12" FontWeight="Bold" Grid.Row="1" Grid.Column="2">Quarter 3</TextBlock>
<TextBlock Grid.Row="2" Grid.Column="0">50000</TextBlock>
<TextBlock Grid.Row="2" Grid.Column="1">100000</TextBlock>
<TextBlock Grid.Row="2" Grid.Column="2">150000</TextBlock>
<TextBlock FontSize="16" FontWeight="Bold" Grid.ColumnSpan="3" Grid.Row="3">Total Units: 300000</TextBlock>
</Grid>
You appear to have placed all your BigGrid elements into a single cell of that layout grid, and the only thing stopping them from appearing on top of each other is the fact you've defined margins. You have not defined a margin for your border, but then defined margins for its children, which means they'll be offset.
Really, for best layout, you want to avoid margins as much as possible and divide your BigGrid into rows and columns. Then place your UI into those cells. If your border is within its own cell you will not have it appear to wrap everything.
In the following XAML, I am trying to wrap the TextBlock which binds to "PortfolioCodes" and "CommentaryText" but it seems that "Wrapping" doesn't work for TextBlock. I tried every possible suggestion I could find on this web site but all in vain. Can someone please help.

Change the width of your third ColumnDefinition from "Auto" to "*", that way it only takes up whatever is left of your horizontal space.
To try to explain this:
Screen area in WPF is distributed in a two pass algorithm. First each visual element asks each child how much space it needs, with an indication of how much is available. These children do the same for their children.
Then each visual element tells each child how much they are actually going to get. These children, again, do the same for their children.
Your code failed to do what you wanted because the Grid in the DataTemplate told its third column children they could have all the horizontal space they wanted ("auto") in the first run. Those textboxes then thought that they wouldn't have to wrap. So they just reported back their desired width, and one line worth of height.
In the second run the Grid found that "auto" turned out to be a little less than what those children wanted. And the Grid still only gave them one line worth of height, so wrapping was out of the question. The children then had no other option left to them but to truncate the text.
When the third column width is set to "*", the grid will tell the children in the that column exactly how many horizontal pixels are left after the first column got their "auto" and the second column got their 15. Now the textboxes can figure out that they may want to wrap, and they report back "Ok, Dad, I'll make do with those measly horizontal pixels, but at least give me what I want in verticals". There is no limit to the vertical space, so they get what they need to present all their glorious content.
Try to give width to your TextBlock, by default TextBlock takes all available space and doesn't wrap text
I am going through the process of designing my first Silverlight application based upon the PivotViewer control from Silverlight 4. I am having problems organizing the bar at the top as per my design:
(source: richard-slater.co.uk)
I have found ways of left aligning the Logo and Title, a way of right aligning the buttons with various combinations of panels however there are two major problems with it.
The XAML looks really really ugly, nesting panels seems to work but doesn't seem like good practice.
I can't seem to find a way of handling resizing the window down without either clipping or overlapping.
I have acheived the best results with the following code:
<StackPanel x:Name="LayoutHeader" Margin="4" Height="50" Grid.Column="0" Grid.Row="0" Orientation="Horizontal">
<Image x:Name="LogoImage" Height="50" Width="50" Source="/EVEMonPivot;component/EVEMonLogoBlue.png" Grid.Column="0" Grid.Row="0" />
<TextBlock x:Name="TitleText" Height="50" Text="EVEMon Pivot" FontSize="40" Grid.Column="1" Grid.Row="0" VerticalAlignment="Center" FontWeight="Bold" Padding="10,0,0,0" />
</StackPanel>
<StackPanel x:Name="NavHeader" Margin="4" Height="50" Grid.Column="0" Grid.Row="0" Orientation="Horizontal" HorizontalAlignment="Right">
<Button x:Name="StackExButton" Style="{StaticResource NavButton}" Click="StackExButton_Click">EVE Online StackExchange</Button>
<Button x:Name="BugsButton" Style="{StaticResource NavButton}">Bugs & Suggestions</Button>
</StackPanel>
I intend to move some of the properties into styles, however it still feels messy.
The above code can also result in the following in small windows:

Is there a better way?
If you don't like nesting panels, a Grid might be a better option. With your four elements, have a five column grid like this:
<Grid HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Image x:Name="LogoImage"
Height="50"
Width="50"
Source="/EVEMonPivot;component/EVEMonLogoBlue.png"
Grid.Column="0" />
<TextBlock x:Name="TitleText"
Height="50"
Text="EVEMon Pivot"
FontSize="40"
Grid.Column="1"
Grid.Row="0"
VerticalAlignment="Center"
FontWeight="Bold"
Padding="10,0,0,0" />
<Button x:Name="StackExButton"
Grid.Column="4"
Style="{StaticResource NavButton}"
Click="StackExButton_Click">EVE Online StackExchange</Button>
<Button x:Name="BugsButton"
Grid.Column="5"
Style="{StaticResource NavButton}">Bugs & Suggestions</Button>
</Grid>
This sets four columns to Auto-size, so they adjust to the size of your UI elements, and the centre column is Star-sized so it fills the rest of the space between them.
While you can use a star-sized grid column to enforce a collapsible region between the controls, you're still left to account for what happens when there simply isn't enough room (eg. 600 pixels of display in a 400-pixel wide area.) What I think you need is a ScrollViewer, which is a ContentControl that lets you determine when scroll bars appear.
In the markup below I am doing 2 things: First, I am using the Silverlight toolkit's DockPanel to isolate the left and right sections of the display (a very similar thing can be accomplished with a 3-column Grid with Cols 0 and 2 set to "Auto" and Col 1 set to "*", but the specific use of Left and Right in the DockPanel may make the intent more readable.) Second, the whole thing is being wrapped in a ScrollViewer with the HorizontalScrollBarVisibility set to "Auto" - when the contents is too big to fit, put up a scrollbar.
