Why doesn't a textbox stretch inside stackpanel WPF? - wpf

<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25*" />
<ColumnDefinition Width="49*" />
<ColumnDefinition Width="25*" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="1" Margin="30" VerticalAlignment="Center">
<StackPanel Orientation="Horizontal">
<TextBlock Margin="0,0,5,0" Text="Username:" />
<TextBox HorizontalAlignment="Stretch"/>
</StackPanel>
</StackPanel>
--Result image--
Im trying to make it so that the textbox will fill the rest of the space inside the current StackPanel.
however the "Stretch" propety doesn't seem to work - why is that?
Is there a different way do it or what am I doing wrong?

A StackPanel always tries to achieve the minimum possible height/width, depending on orientation; therefore, Stretch has no effect. You might want to use a DockPanel instead, which allows children to stretch:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="25*" />
<ColumnDefinition Width="49*" />
<ColumnDefinition Width="25*" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="1"
Margin="30"
VerticalAlignment="Center">
<DockPanel>
<TextBlock DockPanel.Dock="Left" Margin="0,0,5,0"
Text="Username:" />
<TextBox HorizontalAlignment="Stretch"/>
</DockPanel>
</StackPanel>
</Grid>

How to align to a control in the same screen?

In XAML, we typically have <Grid> layout which contains different elements. How do I align a control in one cell of grid to a control in a different cell like below?
(This used to be rather common in traditional applications where controls maybe in different group boxes etc but we still want to align them horizontally in one plane)
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column ="2">
<RadioButton Content="Option1"/>
</StackPanel>
</Grid>
The result is below which is ugly:
In this case, I just want to option1 to aligned centered with the TextBox (which does have custom height).
I can use margins to bring it to the desired position but that's kind of hard coded and not too WPFish.
Should I use binding to tie them directly? Is there a better way? Another way I can think of is to keep making grids within grids but seems like that will over complicate for this simple thing?
Try putting them both in another Grid or a horizontal StackPanel, and put that in one of the parent Grid cells.
The following did the trick, basically wrap the <RadioButton> around in <Border>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<Border BorderBrush="{x:Null}" Height="50">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"/>
</Border>
</StackPanel>
</Grid>
This answer helped.
Now the result is:
Three variants.
The first - I will supplement #zar: I use size binding instead of explicitly assigning a value to the size.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<Border BorderBrush="{x:Null}" Height="{Binding ActualHeight, ElementName=name, Mode=OneWay}">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"/>
</Border>
</StackPanel>
</Grid>
Second - I am implementing #Mark Feldman proposal: Delete StaskPanel and add lines to the grid.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<TextBox x:Name="name" Height="50"/>
<Label Content="John"
Grid.Row="1"/>
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center"
Grid.Column="1"/>
</Grid>
The third - analogous to the first, but without the Border.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width=".5*"/>
<ColumnDefinition Width=".5*"/>
</Grid.ColumnDefinitions>
<StackPanel Grid.Column ="0">
<TextBox x:Name="name" Height="50"/>
<Label Content="John"/>
</StackPanel>
<StackPanel Grid.Column="1" VerticalAlignment="Top">
<RadioButton Content="Option1" Margin="10,0,0,0" VerticalAlignment="Center" VerticalContentAlignment="Center"
Height="{Binding ActualHeight, ElementName=name, Mode=OneWay}"/>
</StackPanel>
</Grid>

Trying to get element alignment correct in xaml

I am trying to get the first label and text box to align to the left side of the screen, and the second label and text box to align to the right side of the screen. What am I missing here? The second set of controls will not align to the right.
Thanks in advance!
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<StackPanel Orientation="Horizontal" Grid.Column="0">
<StackPanel Orientation="Horizontal">
<Label Content="Active Profile"></Label>
<TextBox Name="activeProfileName" Width="100" Height="20"></TextBox>
</StackPanel>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" >
<Label Content="Create A New Profile"
HorizontalAlignment="Right"></Label>
<TextBox Name="activeProfileNamey"
Width="100" Height="20"
HorizontalAlignment="Right"></TextBox>
</StackPanel>
</StackPanel>
</Grid>
The outter StackPanel is your problem. Use Grid instead. Your question is actually a duplicate of the Aligning controls on both left and right side in a stack panel in WPF
Here is the code with Grid:
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Horizontal">
<Label Content="Active Profile"></Label>
<TextBox Name="activeProfileName" Width="100" Height="20"></TextBox>
</StackPanel>
<StackPanel Grid.Column="2" Orientation="Horizontal" HorizontalAlignment="Right" >
<Label Content="Create A New Profile"
HorizontalAlignment="Right"></Label>
<TextBox Name="activeProfileNamey"
Width="100" Height="20"
HorizontalAlignment="Right"></TextBox>
</StackPanel>
</Grid>
</Grid>

Lock element on the right

I have two textboxes in my app, with a variable lenght. One is on the left, the other one on the right. By default their width is pretty little, 30 px. But as they contain a lot of numbers, the textbox on the left shifts the right one and enlarges the window (same thing when the right textbw contains too many numbers). To avoid this, I would like to stabilize the right textbox on the right, even if its width rises.
I've tried to play with the columns size, but not.
<Grid Grid.Row="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="170" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="10" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBox Grid.Column="1" MinWidth="30" Margin="0,0,0,0" Name="maxGmapWest" Text="{Binding Path=Options.MaxGmapWest, ElementName=Window, Mode=OneWay, Converter={StaticResource StringToDoubleConverter}}" PreviewTextInput="Tab1_PreviewTextInput" Width="auto" />
<TextBox Grid.Column="3" MinWidth="30" Margin="230,0,0,0" Name="maxGmapEast" Text="{Binding Path=Options.MaxGmapEast, ElementName=Window, Mode=OneWay, Converter={StaticResource StringToDoubleConverter}}" PreviewTextInput="Tab1_PreviewTextInput" Width="auto" HorizontalAlignment="Left" />
</Grid>
Try something like that markup
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ScrollViewer Grid.Column="0" Width="auto" MinWidth="50" VerticalScrollBarVisibility="Auto" Margin="0,0,0,0" HorizontalAlignment="Left" MaxHeight="40" >
<TextBox Name="maxGmapWest" TextWrapping="Wrap" />
</ScrollViewer>
<ScrollViewer Grid.Column="1" HorizontalAlignment="Right" VerticalScrollBarVisibility="Auto" MinWidth="50" Margin="0,0,20,0" MaxHeight="40">
<TextBox Name="maxGmapEast" TextWrapping="Wrap" />
</ScrollViewer>
</Grid>
maxwidth for textbox=width of column, fixed max height and using ScrollViewer for large text

Horizontal scroll bar prevents text box wrapping

I am trying to make TextBox to wrap text and grow with the Window. That works if I don't set ScrollViewer's HorizontalScrollBarVisibility property. But if I do, TextBox will grow infinitely. The problem is solved by setting MaxWidth property to the TextBox, but in that case TextBox does not grow beyond the MaxWidth value. My idea was then to bind MaxWidth to ColumnDefinition's ActualWidth, but that also doesn't work because ColumnDefinition's ActualWidth property is not a DependencyProperty. Here is my code:
<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Row="0" Grid.Column="0" Text="Name:" Margin="5" />
<TextBox MinWidth="200" Grid.Row="0" Grid.Column="1" TextWrapping="Wrap" AcceptsReturn="True" Margin="5"/>
</Grid>
</ScrollViewer>
Any ideas will be appreciated.
Try this:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="Name:" Margin="5" />
<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Auto" Grid.Column="1">
<TextBox MinWidth="200" TextWrapping="Wrap" AcceptsReturn="True" Margin="5" MaxWidth="{Binding Path=ActualWidth, RelativeSource={RelativeSource AncestorType={x:Type ScrollViewer}}}" />
</ScrollViewer>
</Grid>

DockPanel LastChildFill resizing to MinWidth?

I try to achieve a simple menubar in WPF.
Here is the XAML:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<DockPanel>
<DockPanel Background="Black" VerticalAlignment="Top" LastChildFill="True" DockPanel.Dock="Top" Height="28">
<ToggleButton Content="--" Visibility="Collapsed" />
<StackPanel Orientation="Horizontal">
<Button Content="Add" />
<Button Content="Expand" />
</StackPanel>
<StackPanel HorizontalAlignment="Right" Orientation="Horizontal">
<TextBox Text="Search" MinWidth="80" Width="200" />
<Button Content="X" Margin="0,1,50,0" />
</StackPanel>
</DockPanel>
</DockPanel>
</Page>
It looks good, but when I resize the page to a smaller width, the last child (the Stackpanel with the search textbox) is hiding behind the left items.
Like this:
http://s9.postimage.org/m0tkrobwd/printscreen.png
It would be good if the textbox would resize itself if it has enough space to achieve its MinWidth...Is it possible?
The tricky thing is to give a Control (in your case the SearchTextBox) an alignment but still catch the available space up to MaxWidth. Thanks to this answer.
<DockPanel>
<DockPanel Background="Black" DockPanel.Dock="Top" Height="28">
<ToggleButton DockPanel.Dock="Left" Content="--" Visibility="Collapsed" />
<StackPanel DockPanel.Dock="Left" Orientation="Horizontal">
<Button Content="Add" />
<Button Content="Expand" />
</StackPanel>
<Button DockPanel.Dock="Right" Content="X" />
<Border Name="Container">
<TextBox Text="Search" HorizontalAlignment="Right"
Width="{Binding ElementName=Container, Path=ActualWidth}" MaxWidth="200" />
</Border>
</DockPanel>
</DockPanel>
Container could be another Control too.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="50"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition MaxWidth="200" MinWidth="80"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ToggleButton Content="--" Visibility="Collapsed" />
<Button Content="Add" Grid.Column="1"/>
<Button Content="Expand" Grid.Column="2"/>
<TextBox Text="Search" Grid.Column="4"/>
<Button Content="X" Margin="0,1,50,0" Grid.Column="5" />
</Grid>
Instead of giving MaxWidth and MinWidth to TextBox give it to Grid Column.I hope this will help.
Hi Set MaxWidth and MinWidth for the TextBox Not Width. If you will set the Width then it has highest precedence and hence MinWidth won'nt come into act.I hope this will help.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ToggleButton Content="--" Visibility="Collapsed" />
<Button Content="Add" Grid.Column="1"/>
<Button Content="Expand" Grid.Column="2"/>
<TextBox Text="Search" MinWidth="80" MaxWidth="600" Grid.Column="3" ClipToBounds="True" />
<Button Content="X" Margin="0,1,50,0" Grid.Column="4"/>
</Grid>
Its just because of the size of page is not enough for showing both stackpanel on page. for this you can use the minimum size of the page. that will prevent the damages of the control hiding .
and its also up to you what design you want. you can either use grid rather then stackpanles.
