I want to make this Info.xaml file which is inside my windows form application to be loaded in the my current form but to fill it entirely on the click of the button.

You may use *ElementHost as explained here*
http://blogs.msdn.com/b/calvin_hsia/archive/2007/12/11/6740119.aspx
Alternatively, you may look here too [if you can convert it to a usercontrol]

What I'm wanting to do it make it so when users click on the 'checkbox' it toggles the styling so it appears as below. As you can see in the image below it changes from a gray heart to a red heart. All the bindings and vectors are in the code below. I'm just not sure on how to style the checkbox using my custom paths, and setting up the styling triggers. Hopefully someone can help me out.

This question already has an answer here:
WPF Grid horizontalalignment doesn't work. Sizes don't changes

Closed 8 years ago.
In this window I have many different controls and I want to stretch which is possible
but there are some controls by 'stackGroup', 'listBox1', 'listBox2' that don't stretching.. Why ??
Also is this way i right to do this kind of pages

Same answer as in this question. StackPanel will not respect stretch alignments in the same direction as its orientation. So a StackPanel whose orientation is vertical will not respect a VerticalAlignment of stretch for a child.
listBox1 doesn't stretch because it's VerticalAlignment is stretch and it's container StackPanel has an orientation of Vertical (that's its default). You could change that StackPanel to be horizontal, replace it with another container (such as a DockPanel), or remove it entirely since it only contains one element.
Similar reasoning can be applied to your other issues
I have a .NET 4.0 WPF application using the MVVM pattern and I've been unable to achieve the desired outcome on one of the screens (UserControl as View). I have stripped down most of the page to show the core of the problem. The page consists of a grid with three rows and one column. The first row contains header text and the last row contains a Save button. The middle row contains a grid with one row and column and displays an ObservableCollection in an ItemsControl with a data template of a custom user control. There are ten items in the collection and I want them to display in two columns and five rows so I have a WrapPanel as an ItemsPanelTemplate.
I want the ItemsControl to scroll within the available space but it is expanding to the size of content and most of it is being cropped off the bottom of the page.
I am listing the XAML for user control the ObservableCollection uses as a data template and the XAML for the main page below that. Any help is greatly appreciated.

EDIT: Changed question title as I have removed the ScrollViewer between starting the question and actually posting it. Also, noticed the Save button was in the inner grid rather than outer grid so I have corrected that (no change in rendering).
An ItemsControl does not have its own ScrollViewer like a ListBox. You can either replace you ItemsControl with a ListBox, or simply wrap it in a ScrollViwer, being careful to move the Grid.Row and Grid.Column settings like this:
<ScrollViewer Grid.Row="1" Grid.Column="0">
<ItemsControl HorizontalAlignment="Left" ItemsSource="{Binding Path=Items,
UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}"
ItemTemplate="{StaticResource ShopNotesComponentsTemplate}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Width="300" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
I have a WPF listbox and have updated the list item data template to have essentially a 3 column layout.
I would like:
|status color|name| buttons|
These are probably CSS terms but I want to float the status color and name to the left, which I've done, then I would like the buttons to be floated to the right, and always stay to the right even as the window gets wider.
I feel like I'm so close, the list item widths grow when the window gets wider, all I feel I have to do is tell the buttons to float right but can't figure out how. I've tried stack panels, a grid with a auto|*|auto column layout (With a stretch on the last column) and I've tried a dockpanel.

And an image of what I'm trying to achieve:
The problem is at the first level below DataTemplate, here:
<StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch">
By its nature a StackPanel will align items to the left, so it's not a layout that's well suited to what you want to do. Instead try using a Grid with two columns, giving the left column Width=* and the right Width=Auto.
<ListBox HorizontalContentAlignment="Stretch">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<StackPanel Grid.Column="0" Orientation="Vertical">
...
</StackPanel>
<DockPanel Grid.Column="1" VerticalAlignment="Center">
...
</DockPanel>
</Grid>
<DataTemplate>
</ListBox.ItemTemplate>
<ListBox>
In your ItemContainerStyle, set the HorizontalAlignment to Stretch. I believe it is Left by default, which may be causing the Grid or StackPanel or whatever container you use to collapse.
I have a WPF user control inside windows form project and I have a problem. Every second time my app crashes as element host can't load data in user control.

You might want to check if the xml document that contains the data is still locked by the previous app.
So, start up the app. Close it. Check to see if the xml file is still in use.
Also,: add exception handling so you know what exception is being thrown. Use at least Application.DispatherUnhandledException
