SilverLight: how to align buttons in stackpanel center and right - silverlight

In the bottom "row" (inside of StackPanel with Horizontal orientation?) of my SilverLight control I would like to display two things:
"Save" button - to center-aligned
Text field with small text (kind of Version) - to be aligned to the right
How to do that? If I put both inside of stackpanel their alignement will be the same... Wrap panel just tie them together...
Please advise.
Thank you.

Within your stack panel create a grid with 2 columns then align each column independantly.
<StackPanel x:Name="Layout" Background="Black">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*"></ColumnDefinition>
<ColumnDefinition Width="2*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Label Name="Left" HorizontalAlignment="Left" grid.column=1/>
<Button x:Name="Button2" Content="And me!" HorizontalAlignment="Center" ></Button>
</Grid>
</StackPanel>
No the perfect syntax but its just to demonstrate the idea.
Hope this helps!

Simple WPF 'panel' issue

a 'simple' about controls layout in wpf. There is a custom control with a grid in wich there is 'panel' on this panel there are three elements two buttons and slider between them. Right button must be anchored to right side of the 'panel', left button to the left side of 'panel' and the slider must FILL ALL THE FREE SPACE BETWEEN buttons. The width(and height) of buttons and grid will be set dinamycaly in the code after. The question is - what kind of 'panel'I must use and how to make it to operate with given task? (stack, dock - have no such functionality even with this "horizontal stratching")
In WinForms - there are no problem width of slider = widthOfGrid - (widtOfBothButtons)
Is this possible to do it in wpf? Or I must compose the code like above in some constructor-like functions?
(offtop- As for me this is a typical task for wpf control and I am surprized that it has too little automatic to solve it)
the code:
<UserControl x:Class="WpfApplication1.UserControl2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="42" d:DesignWidth="291">
<Grid x:Name="gridCtrl">
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="clnmLbl" Width="Auto"/>
<ColumnDefinition x:Name="clnmPnl" />
</Grid.ColumnDefinitions>
<Label x:Name="lblText" Grid.Column="0" Content="" VerticalAlignment="Center">
</Label>
<DockPanel x:Name="pnlDock" Grid.Column="1">
<Button x:Name="btnLeft" HorizontalAlignment="Left" DockPanel.Dock="Left">
</Button>
<Border x:Name="BorderOfSlider" BorderBrush="#FF000000" BorderThickness="3,3,3,3" CornerRadius="8,8,8,8" >
<Slider x:Name="sldSlider" HorizontalAlignment="Stretch" VerticalAlignment="Center" >
</Slider>
</Border>
<Button x:Name="btnRight" HorizontalAlignment="Right" DockPanel.Dock="Right">
</Button>
</DockPanel>
</Grid>
</UserControl>
That sounds exactly like what a DockPanel does.... it will Dock controls to the sides of the panel, and by default the last control added will stretch and fill all remaining space
<DockPanel>
<Button DockPanel.Dock="Left" Content="Left Button" />
<Button DockPanel.Dock="Right" Content="Right Button" />
<Slider />
</DockPanel>
Also if you're new to WPF, I'd recommend taking a look at this site for a quick visual view of WPF's layout controls.
Edit
Make sure your control that fills all remaining space is the last item added to your DockPanel. If not, it will use a default value of DockPanel.Dock="Left"
There are several ways to do it:
1) DockPanel. Left button will occupy some place at the left side of DockPanel, right button will occupy required space on the right side of remaining space. The rest will be used to display Slider.
<DockPanel>
<Button DockPanel.Dock="Left">Left button</Button>
<Button DockPanel.Dock="Right">Right button</Button>
<Slider />
</DockPanel>
2) Grid. Create grid with 3 columns. Left and right columns will take only required space, the rest will be given to the center column.
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Button Grid.Column="0">Left button</Button>
<Slider Grid.Column="1" />
<Button Grid.Column="2">Right button</Button>
</Grid>

wpf - size problems for grid used as tabitem

I am having some problems with a menu that is displayed as tabs (displayed vertically on the left side)
I have defined a headertemplate that defines a grid consisting of two columns where the first holds a textblock with the text retrieved via binding. The second column holds an image whose visibility is tied to a property - this image is used by validation and shown when data entered in another view has been validated.
The problem I have is getting the columns to share the same width. Example:
Text1| Image
MuchLongerText| Image
This looks a bit wonky and so am trying to get the Images to line up but can't seem to do this. The HeaderTemplate has a datatemplate specified as below
<Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Text="{Binding Name}" HorizontalAlignment="Left" VerticalAlignment="Center"/>
<Image Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Center" Width="20" Height="20" x:Name="ValidationImage" Source="/Images/validationimage.bmp"/> </Grid>
I've tried putting it in a stackpanel and using sharedsize but no luck. Any help with this would be much appreciated!
Cheers

Take a look at the Grid.IsSharedSizeScope and DefinitionBase.SharedSizeGroup properties.

WPF separator between grid buttons

I have a grid with 4 buttons...1 row, 4 columns. I am looking for a way to visually group the two buttons on the left from the two on the right. I was looking for a way to do this with a separator but it doesnt seem to be playing nice with Grid, preferring StackPanel.
Is this the right control?
If so, how does one make the thing separate the columns (populated with buttons in this case)?
Thanks.
In case anyone else stumbles across this, easiest solution:
<Separator Style="{StaticResource {x:Static ToolBar.SeparatorStyleKey}}" />
Have you tried a GridSplitter?
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Height="*" />
<ColumnDefinition Height="Auto" />
<ColumnDefinition Height="100" />
<ColumnDefinition Height="100" />
</Grid.ColumnDefinitions>
<Button/>
<Button/>
<GridSplitter ResizeDirection="Columns" Grid.Column="2" Height="Auto" Width="4" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0"/>
<Button/>
</Grid>
I usually use the simple choice to add a column with a fixed width between the buttons
You can actually use a different background color or insert an image
You can use Separator if you style it correctly. By default it creates a horizontal line. You have to apply different styling to make it vertical.
See this post for how to style it as a vertical line in a WPF Grid:
CodeProject discussion
The discussion also mentions that StatusBar applies some styling to Separator elements, as long as you don't wrap them in StatusBarItems. Perhaps StackPanel does something similar.

Align items in a stack panel?

I was wondering if I can have 2 controls in a horizontal-oriented StackPanel so that the right item should be docked to the right side of the StackPanel.
I tried the following but it didn't work:
<StackPanel Orientation="Horizontal">
<TextBlock>Left</TextBlock>
<Button Width="30" HorizontalAlignment="Right">Right<Button>
</StackPanel>
In the snippet above I want the Button to be docked to the right side of the StackPanel.
Note: I need it to be done with StackPanel, not Grid etc.
You can achieve this with a DockPanel:
<DockPanel Width="300">
<TextBlock>Left</TextBlock>
<Button HorizontalAlignment="Right">Right</Button>
</DockPanel>
The difference is that a StackPanel will arrange child elements into single line (either vertical or horizontally) whereas a DockPanel defines an area where you can arrange child elements either horizontally or vertically, relative to each other (the Dock property changes the position of an element relative to other elements within the same container. Alignment properties, such as HorizontalAlignment, change the position of an element relative to its parent element).
Update
As pointed out in the comments you can also use the FlowDirection property of a StackPanel. See #D_Bester's answer.
Yo can set FlowDirection of Stack panel to RightToLeft, and then all items will be aligned to the right side.
For those who stumble upon this question, here's how to achieve this layout with a Grid:
<Grid>
<TextBlock Text="Server:"/>
<TextBlock Text="http://127.0.0.1" HorizontalAlignment="Right"/>
</Grid>
creates
Server: http://127.0.0.1
Could not get this working using a DockPanel quite the way I wanted and reversing the flow direction of a StackPanel is troublesome. Using a grid is not an option as items inside of it may be hidden at runtime and thus I do not know the total number of columns at design time. The best and simplest solution I could come up with is:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="1" Orientation="Horizontal">
<!-- Right aligned controls go here -->
</StackPanel>
</Grid>
This will result in controls inside of the StackPanel being aligned to the right side of the available space regardless of the number of controls - both at design and runtime. Yay! :)
This works perfectly for me. Just put the button first since you're starting on the right. If FlowDirection becomes a problem just add a StackPanel around it and specify FlowDirection="LeftToRight" for that portion. Or simply specify FlowDirection="LeftToRight" for the relevant control.
<StackPanel Orientation="Horizontal" HorizontalAlignment="Right" FlowDirection="RightToLeft">
<Button Width="40" HorizontalAlignment="Right" Margin="3">Right</Button>
<TextBlock Margin="5">Left</TextBlock>
<StackPanel FlowDirection="LeftToRight">
<my:DatePicker Height="24" Name="DatePicker1" Width="113" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" />
</StackPanel>
<my:DatePicker FlowDirection="LeftToRight" Height="24" Name="DatePicker1" Width="113" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" />
</StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Text="Left" />
<Button Width="30" Grid.Column="1" >Right</Button>
</Grid>
If you are having a problem like the one I had where labels were centered in my vertical stack panel, make sure you use full width controls. Delete the Width property, or put your button in a full-width container that allows internal alignment. WPF is all about using containers to control the layout.
<StackPanel Orientation="Vertical">
<TextBlock>Left</TextBlock>
<DockPanel>
<Button HorizontalAlignment="Right">Right</Button>
</DockPanel>
</StackPanel>
Vertical StackPanel with Left Label followed by Right Button
I hope this helps.
for windows 10
use relativePanel instead of stack panel, and use
relativepanel.alignrightwithpanel="true"
for the contained elements.
Maybe not what you want if you need to avoid hard-coding size values, but sometimes I use a "shim" (Separator) for this:
<Separator Width="42"></Separator>

restricting the size of wpf dockpanel region

Is there a way you can pin a wpf dockpanel? I have searched on the net and I have not found any functionality that will allow this. What I want is to lock the size of a dockpanel's dock regions. For example I want the right region"s width to stay locked all the time. The only solutions to this that I have seen are 3rd party controls. Does anyone know of a way to restrict the width of these regions? Thanx in advance.
You can set the MaxWidth property of the control you are docking.
According to your additional explanations, you have the following layout:
<DockPanel>
<ItemsControl DockPanel.Dock="Left"/>
<StackPanel DockPanel.Dock="Right"/>
</DockPanel>
The first thing I recommend is to add LastChildFill="False" to the DockPanel so your left and right parts grow unrelated.
Then you have to decide what happens when the number of items in the ItemsControl increase. You can make a horizontal scrollbar appear, make them wrap, and so on.
Yes, I had LastChildFill = "False" already set, plus the my items control is already in a scrollviewer with a horizontal template applied. With this setup the initial layout looks great in the row. The only problem is when the itemscontrol grows too big and hits the right dock, it will always force the right dock to go smaller even though the minwidth is set on the grid that is contained within. Here is an example of my code:
<DockPanel Grid.Row="1" LastChildFill="False">
<!--Horizontal template applied-->
<ScrollViewer DockPanel.Dock="Left">
<ItemsControl/>
</ScrollViewer>
<Grid DockPanel.Dock="Right" MinWidth="200">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Button Grid.Column="0"/>
<Button Grid.Column="1"/>
</Grid>
</DockPanel>
Thanks for the help . . . any other ideas?
