WPF StackPanel


The StackPanel in WPF is a simple and useful layout panel. It stacks its child elements below or beside each other, dependening on its orientation. This is very useful to create any kinds of lists. All WPF ItemsControls like ComboBox, ListBox or Menu use a StackPanel as their internal layout panel.

  <TextBlock Margin="10" FontSize="20">How do you like your coffee?</TextBlock>
  <Button Margin="10">Black</Button>
  <Button Margin="10">With milk</Button>
  <Button Margin="10">Latte machiato</Button>
  <Button Margin="10">Chappuchino</Button>

Stack Items horizontally

A good example for a horizontal stack panel are the "OK" and "Cancel" buttons of a dialog window. Because the size of the text can change if the user changes the font-size or switches the language we should avoid fixed sized buttons. The stack panel aligns the two buttons depending on their desired size. If they need more space they will get it automatically. Never mess again with too small or too large buttons.

<StackPanel Margin="8" Orientation="Horizontal">            
   <Button MinWidth="93">OK</Button>
   <Button MinWidth="93" Margin="10,0,0,0">Cancel</Button>

Can I stretch the last element in the empty space of the stack panel without giving it any width or height? any help if possible!

Hi Tormentor,
It's not possible to strech the last element of a stack panel because the stack panel has "infinite" size for its elements. You can solve your problem by using a DockPanel and dock all contained elements to top and set LastChildFill to true.

oh just so you know. in english 'Chappuchino' is a gay sex act in which a man wearing assless chaps shits upon the chin of his lover (chaps+poo+chin+OMG!) you had probably mean cappuccino, but just wanted to make you aware in case site started drawing the attention of chappuchino lovers.

I'm guessing this article has been left unfinished? It barely begins to describe many of the properties of a stackpanel.

Hi Mukesh,
The default is that the control will be centered. Use the HorizontalAlignment on the Control to set it specifically
<StackPanel Height="100" HorizontalAlignment="Left" Margin="502,98,0,0" Name="stackPanel1" VerticalAlignment="Top" Width="200">
<Button Content="Button" HorizontalAlignment="Center" Height="23" Name="button3" Width="75" />
