I'm not a wpf expert, so maybe the problem is really simple than appear. Anyway, I made a stackpanel with this structure:
<StackPanel Orientation="Horizontal">
<Label Content="Match" FontWeight="Bold"/>
<Label Content="Foo" HorizontalAlignment="Right"/>
</StackPanel>
How you can see I set the orientation to horizontal so I can have both label in the same row. I need also to align the second label "Foo" to right. I tried setting the HorizontalAlignment property, but, the label is stuck on the same position. What I can do for fix this?
The simplest answer is that you can't.
Stackpanel is made to stack things after each other.
You can do it either vertically of horizontally and you can align the stackpanel to the right or left but you cannot align the items inside it.
You can use Grid or another container instead.
<Grid>
<Label Content="Match" FontWeight="Bold" HorizontalAlignment="Left"/>
<Label Content="Foo" HorizontalAlignment="Right"/>
</Grid>
StackPanel does not support the individual alignment of the child controls. However you can set the alignment of the whole stackpanel. However its not the case here.
What you can do is put your labels in a Uniform Grid of 1 row and 2 columns.
<UniformGrid Rows="1" Columns="2">
<Label Content="Match" FontWeight="Bold"/>
<Label Content="Foo" HorizontalAlignment="Right"/>
</UniformGrid>

In the header of my Expander I am trying to place a few buttons. I want these buttons to be on the far right, however any element I add inside the header is reduced to it's minimum size regardless of the horizontal alignment rules.
<StackPanel Grid.ColumnSpan="4" Grid.RowSpan="4">
<Expander ExpandDirection="Down" IsExpanded="True" FontSize="14" FontWeight="Bold" Margin="5" BorderThickness="1" BorderBrush="#FF3E3D3D">
<Expander.Header>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
<TextBlock Text="Greeting and Opening" VerticalAlignment="Center" HorizontalAlignment="Center"/>
<Button x:Name="GreetingCheckAll_Button" Content="Check All" HorizontalAlignment="Center" Margin="5,0,0,1" VerticalAlignment="Center"/>
</StackPanel>
</Expander.Header>
I want to get that button to the far right instead of to the left, as you can also see the stack panel element is only as large as it needs to be. What do I need to do to allow for the stack panel to stretch across the entire width so I can align the button to the right?
Thanks guys.
Edit: Tried using the docking panel suggestion instead (after looking at the panels overview, that seems the right way to go). I still end up with the same constraints, the panel will not stretch across the entire width of it's parent element unless I manually set it's width in pixels.
What you want is not a StackPanel, you want something like the DockPanel or Grid
Where you set the first Content as TextBlock, then Dock a button to the right.
Or a Grid.
I got a weird problem on my xaml, in a stackPanel.
My stackPanel contains a textbox, and a button.
This should be on the same line (if possible, depending on the text width).
The problem is :
if the stackPanel have Orientation="Vertical", the button will go to the line bellow the text.
if the stackPanel have Orientation="Horizontal" , the line will not doing any break line, so all the line will go out of my grid.
<StackPanel Name="spRemplir"
Grid.Row="2"
Grid.ColumnSpan="6"
Width="560"
Margin="5,5,5,5"
Orientation="Horizontal"
VerticalAlignment="Center">
<TextBlock FontWeight="Bold"
Text={Binding Text}
TextWrapping="Wrap"/>
<Button Name="btRemplir"
Margin="5,0,0,0"
Width="150"
Content="Remplir"/>
</StackPanel>
How can I obtain a stackPanel, that will break lines if necessary, and have a text and a button on the same line?
Update with Wrapanel thanks to Eli Arbel :
<toolkit:WrapPanel Name="spRemplir"
Grid.Row="2"
Grid.ColumnSpan="6"
Margin="5,5,5,5"
Width="560"
Orientation="Horizontal">
<TextBlock FontWeight="Bold"
Text={Binding Text}
TextWrapping="Wrap"/>
<Button Name="btRemplir"
Content="Remplir"/>
</toolkit:WrapPanel>
But, the button still on the next line, while there is enough space after the text on the same line.
Itried removing the Width on the panel, but then, there is no more wrapping...
I don't understand. Even if there is stackPanel on the same Grid, they should not disturb the wrap panel right?
Thank you.
You can try a WrapPanel from the Silverlight Toolkit. Note this panel will not allow you to stretch the items to the container width.
You should also look into removing the fixed Width of the panel.
Try using a Grid instead of a StackPanel. The problem with StackPanel is that they do not report up the Visual Tree that they are out of room. This is not a bug, it's just the way they are and it's appropriate when you need it. But I avoid them except on the innermost elements. But don't have StackPanels in StackPanels as you will lose TextWrapping/Scrolling and just have elements fall of the right or bottom of the page.
Second, make sure that your outer container is Set so that the width is Constrained. For example, in your layout root, give it one Column, and set the Width for * which means = "The available space, but not more"
Once you have your outer container constrained, then your TextBlock will wrap properly.

Consider using a WrapPanel instead stack panel: http://wpftutorial.net/WrapPanel.html
I have a groupbox that contains nested stack panels that aren't filling in the groupbox entirely. I would like to have all the stackpanels evenly spaced out filling in the entire groupbox. I have attempted changing the VerticalContentAlignment to Stretch for the groupbox, but that does not work.
<GroupBox>
<StackPanel>
<StackPanel Orientation="Horizontal">
<Label Content="Test1" />
<Label Content="Test2"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<Label Content="Test3" />
<Label Content="Test4"/>
</StackPanel>
</StackPanel>
</GroupBox
StackPanels by default only use as much space as is required to display whatever they contain. If you need different behavior you either need to roll your own version of a stackpanel or use another container. Both Grids/Dockpanels work fine as substitutes.
Let's say I have a simple TextBox next to a Label:
<StackPanel>
<StackPanel Orientation="Horizontal">
<Label Margin="3">MyLabel</Label>
<TextBox Margin="3" Width="100">MyText</TextBox>
</StackPanel>
...
</StackPanel>
This yields the following result:
As you can see, the base lines of MyLabel and MyText are not aligned, which looks ugly. Of course, I could start playing around with the margins until they match up, but since this is such a common requirement I'm sure that WPF provides a much easier and more elegant solution, which I just haven't found yet...
This behaviour is, I think, caused by the fact that the TextBox defaults to a vertical alignment of Stretch, which causes it to fill the available space and have the extra couple of pixels under the text. If you use this instead:
<StackPanel>
<StackPanel Orientation="Horizontal">
<Label >MyLabel</Label>
<TextBox VerticalAlignment="Center" Width="100">MyText</TextBox>
</StackPanel>
</StackPanel>
... you should see a cleaner result.
What do you think?
<StackPanel Orientation="Horizontal">
<Label Margin="3" VerticalContentAlignment="Center">MyLabel</Label>
<TextBox Margin="3" VerticalContentAlignment="Center" Width="100">MyText</TextBox>
</StackPanel>
I achieved that look in Kaxaml with:
<StackPanel Orientation="Horizontal">
<Label Margin="3" VerticalAlignment="Center">MyLabel</Label>
<TextBox Margin="3" Width="100" VerticalAlignment="Center">MyText</TextBox>
</StackPanel>
I know that this is an old answer, but for here's an example for those who seek another way, where you don't need to rely on a fixed textbox width:
Instead of StackPanel, use a DockPanel and .Dock.
This proves to be very handy when used inside a Grid.
<DockPanel Grid.Column="2" Grid.Row="2">
<Label Content="SomeTitle:" DockPanel.Dock="Left"></Label>
<TextBox x:Name="SomeValueTextBox" VerticalAlignment="Center" DockPanel.Dock="Right"></TextBox>
</DockPanel>
This question is not as trivial as it looks and the accepted answers lacks details. If you try custom heights with the controls, you will see issues.
First, this is the correct implementation as answered by User7116.
<StackPanel Orientation="Horizontal">
<Label Margin="3" VerticalAlignment="Center">MyLabel</Label>
<TextBox Margin="3" Width="100" VerticalAlignment="Center">MyText</TextBox>
</StackPanel>
The tricky part is that there two level of vertical alignments here so understand how the alignments works.
When we specify alignment for a control, we are telling it how to position itself in the parent container (See documentation). So when we specify VerticalAlignment="Center"> to the TextBox we are telling it that this TextBox should appear vertically centered in parent stackpanel.
Now the actual text inside that TextBox could also use vertical alignment within that TextBox! This is the 2nd level and actually quite tricky and is answered here.
If you experiment with setting the Label's height above to say 50 as well, you will see they will not align again. This is because Label is now taking larger area and its text inside that area is not vertical aligned so it doesn't look aligned again.
The code for above is:
<StackPanel Orientation="Horizontal" VerticalAlignment="Center">
<Label Margin="3" VerticalAlignment="Center" Height="50">MyLabel</Label>
<TextBox Margin="3" VerticalAlignment="Center" Width="50" Height="50">MyText</TextBox>
</StackPanel>
Luckily when control height is default (like label control), it's just tall enough to contain the text so the inside alignment doesn't matter. But it comes into play if someone is setting custom heights for these controls and its better to understand how this works.
The labels in the example below (WPF/XAML) just parade off the screen, no wrapping occurs. Removing the orientation works, but doesn't provided the needed functionality/look & feel. Any ideas how to make the WrapPanel wrap to the current size of the StackPanel?
<Window Height="300" Width="600">
<StackPanel Orientation="Horizontal">
<WrapPanel>
<Label Height="28" Name="label1" Width="120">First Name</Label>
<Label Height="28" Name="label2" Width="120">John</Label>
<Label Height="28" Name="label3" Width="120">Last Name</Label>
<Label Height="28" Name="label4" Width="120">Smith</Label>
<!-- ...more labels!... -->
</WrapPanel>
<!-- ...other controls/panels... -->
</StackPanel>
</Window>
You can bind the WrapPanel's MaxWidth to the StackPanel's ActualWidth.
I haven't tried this, but basically:
<WrapPanel MaxWidth="{Binding ActualWidth, ElementName=myStackPanel}"/>
What you're doing isn't possible because of the algorithm that StackPanel uses when doing horizontal layout. It's basically going to ask each child element how big it wants to be and however much space it asks for it's going to give it.
You would either need to:
Set a Width or MaxWidth on the WrapPanel.
Use a WrapPanel as the outer panel in place of the StackPanel.
