trying first time WPF user. I read through some WPF layout docs but am not getting the hang of the layout of buttons. I'm trying to get the layout below -- where there's a button in the lower left corner and two in the lower right.
Can this be done with a single StackPanel? I tried unsuccessfully with this along with the HorizontalAlignment attributes of the buttons.
Is it more appropriate to be using a 1 row, 2 column grid, with each cell having a StackPanel?
Any suggestions much appreciated, thanks!
Personally, I tend to prefer doing this with a Grid, ie:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Button Grid.Column="0" Width="100">b1</Button>
<Button Grid.Column="1" Width="100">b2</Button>
<Button Grid.Column="2" Width="100">b3</Button>
</Grid>
This will cause the 2nd & 3rd columns to fit their contents, and the first to fill the rest of the space. If you place each button in the appropriate column, you'll get that layout. (Note that you'll likely want to adjust the sizing and margins on the buttons to get nice spacing, as well.)

I have the following xaml:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="150"/>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Left" Grid.Column="1">
<TextBox Width="120" Text="Search" Margin="10"/>
<Button>Search</Button>
</StackPanel>
</Grid>
In both the designer and the running application the right edge of the button is cut off, but only if the textbox has a margin on the right side. How do I create separation between the two without cutting off the buttton. Is this a bug?
Edit:
The StackPanel is in Column 1 not Column 0. Additionally, the button border reappears after the button has been clicked. Window size is 525 and the grid is the only thing in it.
Set your first ColumnDefintion's Width to Auto
I'm guessing that since the width is not defined, it's making them both *, which means they'll be of an equal width. By setting the 1st to Auto you're telling it to take up however much space it needs, then letting the 2nd column fill the remaining space.
It isn't a bug- the combination of the 120px of width (of the text box) + the width of the button when it's contents is the string "Search" (whatever that may be) + the 150px of the first column is wider than whatever is the space allocated by the container of the Grid.
What did you expect to happen? Scrollbars?
I have a WPF UserControl with two Grids above each other. The bottom Grid is in a ScrollViewer. The idea is to have the first Grid be the header of the second Grid. I'm having trouble with the width of the columns however. Both Grids should take up all the space they can (the width of the Window), but the top Grid should of course be a little less wide, because there's a scrollbar on the right of the bottom Grid.
This is the simplified Xaml I've got:
<UserControl>
<DockPanel>
<Grid DockPanel.Dock="Top">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
</Grid>
<ScrollViewer>
<Grid>
<Grid.ColumnDefintions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefintions>
</Grid>
</ScrollViewer>
</DockPanel>
</UserControl>
This renders fine actually, except that the most right column of the top Grid extends over the scrollbar, which I want to avoid.!
Here is an image of the result: Grid column and width of scrollbar. The red indicates where the column/cell is now, but I want it to stop at the blue line. I've tried SharedSizeGroups, but that seems to make my Grids small again (not take up the full space of the window).
<ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Name="sv">
<Grid MinWidth="{Binding ElementName=sv, Path=ViewportWidth}" MinHeight="{Binding ElementName=sv, Path=ViewportHeight}" />
</ScrollViewer>
The problem is setting up a correct dependency between the ScrollViewer container size and the grid size. Let us consider just the width: the binding above allows the ScrollViewer to expose the horizontal scrollbar only if necessary:
enlarging a single column of the grid (eg. with a splitter) does not provoke the resizing of the other columns (which would happen if you bind Width instead MinWidth).
Using the ViewportWidth instead of ActualWidth takes into account the scrollbar width, if there is one.
Just try
Found the solution here. I gave my top Grid a Width:
Width="{Binding ElementName=BottomGrid, Path=ActualWidth}"
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.
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>
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?
