I want to put lots of controls inside a StackPanel and user can scroll up and down. I have a simple StackPanel inside a grid.
<Grid>
<StackPanel>
</StackPanel>
</Grid>
If I'm not wrong, I've seen that StackPanel scrolls, but now it is not working. Does it support scrolling or it is not supported at all? ( I prefer not to put it inside a ScrollViewer). thanks
Nothing really scrolls unless it has a ScrollViewer inside. When you do it like you're doing it now, you'll see only the items that fit on the screen, and others will be 'out of screen borders'.
So I'm afraid you'll have to add a ScrollViewer. It's actually a good thing that StackPanel doesn't scroll by default.

When vertically scrolling into view, I can pull the last row into view, but on releasing the drag, the last row springs back (partially) out of view. I think inaccuracy of measure can be attributed to a grid that I'm using as the listbox's header but I'm currently unable to fix this to that they work together correctly.
<Border>
<StackPanel>
<ScrollViewer ScrollViewer.HorizontalScrollBarVisibility="Auto">
<StackPanel>
<Grid x:Name="_headers"/>
<ListBox x:Name="_dataGrid"/>
</StackPanel>
</ScrollViewer>
</StackPanel>
</Border>
**Update
This example removes the scroll and also suffers from the same truncated row problem as the example above. The header grid row also doesn't scroll horizontally with the listbox rows which is an even bigger problem for my solution.
<Border>
<StackPanel>
<Grid x:Name="_headers"/>
<ListBox x:Name="_dataGrid"/>
</StackPanel>
</Border>
It's because you put ScrollViewer inside StackPanel. StackPanel doesn't limit control's size so the ScrollViewer can grow forever and never scroll properly. Its size must be limited. Grid can do it perfectly (if only the height of the row is set to *, not Auto).
Also, in my opinion you shouldn't put ListBox inside ScrollViewer, because ListBox already has its own scroll feature.
Never ever use a ListBox inside a ScrollViewer, you will run into scrolling conflicts.
As far as I can see, you need to add a header to your list. LongListSeelctor might be the best option, since it has got a Header property (also Footer):

I'm trying to create grid with listbox with Scrollbar.
It's done somehow like that:
<Grid>
<ListBox Name="xxx" ItemsSource="{Binding}" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Visible">
....
</ListBox>
</Grid>
The problem is that if I use scrollbar, then the size of bar-button jumps back and forward within scrolling. If I remove ScrollViewer from properties and instead put ListBox in ScrollViewer tag, then everything is working perfect, except of terrible performance of rerendering UI (resize, move window, resource consuming). According to google it does "disable virtualization". This sounds crazy that there's no simple solution to get properly working scrollbar and usable UI without issues.
Is there compromise for both of these things? Virtualization + properly working scrollviewer with fixed size of scrollbar button.
I am using the Fluidkit ElementFlow control that I use to display a UserControl that contains textblock with a ScrollViewer as well as button and when they are displayed in the ElementFlow control, all of the buttons and the ScrollViewer seem to be disabled because I can't scroll the ScrollViewer scrollbar and even a simple action as hovering over a button doesn't do anything to the button.
Below is an example of the TextBlock in a ScrollViewer that does not allow for scrolling when used in the ElementFlow.
How can this be fixed?
<ScrollViewer
Height="1200" Width="800"
MaxHeight="1200" MaxWidth="800"
VerticalScrollBarVisibility="Auto">
<TextBlock
Height="Auto" Width="800"
MaxWidth="800"
FontSize="20"
Text="Super long text"
TextWrapping="Wrap"/>
</ScrollViewer>
Just looking over the source code for the project, it looks like it is creating a 3D mesh, and painting the controls on the mesh. This would prevent all user interaction. I don't think there is an easy way to work around this.
However, since you have the source code, you can do the work yourself to make it happen. You're going to need to modify how the ElementFlow represents its items. Look at the CreateMeshModel function. It is currently creating a mesh and applying a VisualBrush to it. Instead, look at the blog post Interacting with 2D on 3D in WPF to figure out what needs to happen.
I'm trying to recreate the layout of the Weather app in XAML / C#. I have a ListView full of ListViewItems. It is one of several objects within a ScrollViewer. The end result should be that the user can scroll horizontally through the Objects, but stop on the ListView and scroll vertically.
For the effect to work, the ScrollViewer must match the height of the page, and the ListView must match the height of the ScrollViewer, without stretching it.
I can't figure out how to do this without using code-behind to find the Window.Current.Bounds and apply the height to the ScrollViewer, this seems like a dirty hack. Is there a way to do this purely in XAML?
The ListView has its own scrollbar stuff, without needing a ScrollViewer. Otherwise to make things stretch it should be pretty easy - how are you putting things in the ScrollViewer? Through a Grid? A StackPanel?
This may be what you are looking for, but you may find it useful to achieve a 'weather app' look and feel:

I have read that I can't have my dockpanel scroll so im looking for alternatives
I want to have a lot of slider controls(unknown number) left to right in a panel of some sort that can scroll so I can view all the sliders. I tried with dock panel but of course that didn't work. What can I do to make the dockpanel work or what do I replace dockpanel with(the replacement would need to support children)?
Thanks!

here is the idea but it needs to scroll horizontally
David Brunelle Does work but its not quite what I want. Id like the scroll bar to be on the top of the control and not attached to the bottom of the window.
I'm not sure I understand, but you can use a panel within a ScrollViewer
Something like this :
<ScrollViewer VerticalScrollBarVisibility="Auto">
<StackPanel Margin="2,2,2,2">
...
</StackPanel>
</ScrollViewer>
This will allow for vertical scrolling. You could do the same for horizontal scrolling. I do not know if this would work with a docking panel, but I know it does with a stack panel.
Hope that helps.
I would use a ListBox as it will handle the scrolling part for you, then you can set the ItemTemplate (if you want) and you can use data binding (using an ObservableCollection or a DataView
