Ohh, I'm sorry. Just not familiar with MSDN site. I had to download entire project provided.  There were lots of C Sharp code files, naive little boy Pew.
Thank you Richard.

Perhaps if you tell us what problems you're having - the full details of the error, and the line it occurs on - then someone might be able to help you.
Otherwise, you might want to take a look at a MahApps.Metro[^], which provides a relatively easy way to customize your WPF windows.

hello guys, there's an issue as follows:
When I change resolution of the screen, my controls so to speak - "swim". You can see it if you'll start my simpliest test apps (a code is provided).
A question: How to get my controls to be responsive to resolution alteration?

thanks in advance!
P.S. To catch an issue, just maximaze/minimaze apps screen.

Avoid layout out controls using margins, and avoid specifying a width and height for controls that don't need them.
For basic layout, use one of the standard layout panels, and use the horizontal and vertical layout properties to position your controls.
If you're creating a drawing, it's usually better to use the Canvas, and set the Canvas.Left and Canvas.Top positions instead.
If you want the drawing to resize with the container, you'll probably want a Viewbox as well.
Panels Overview | Microsoft Docs[^]
Canvas Class (System.Windows.Controls) | Microsoft Docs[^]
Viewbox | Microsoft Docs[^]
Eg:
<Grid ShowGridLines="True">
<Grid.RowDefinitions>
<RowDefinition Height="80"/>
<RowDefinition Height="1*"/>
<RowDefinition Height="160"/>
</Grid.RowDefinitions>
<Canvas Grid.Row="1" HorizontalAlignment="Center" Width="1024" ClipToBounds="True">
<Path Data="M319.5,255.83333 L511.5,255.47633" Fill="#FFF4F4F5" HorizontalAlignment="Left" Height="1.357" Canvas.Left="255.468" Canvas.Top="175.5" Stretch="Fill" Stroke="Black" VerticalAlignment="Top" Width="193"/>
...
<TextBlock x:Name="textBlock2" HorizontalAlignment="Left" Canvas.Left="387.968" Canvas.Top="10" Grid.Row="1" TextWrapping="Wrap" Text="Center vert. line of the 1024x768 screen" VerticalAlignment="Top"/>
</Canvas>
<TextBlock x:Name="textBlock1" HorizontalAlignment="Center" TextWrapping="Wrap" Text="I need that Row" VerticalAlignment="Center" FontSize="24" TextAlignment="Center"/>
<TextBlock x:Name="textBlock1_Copy" HorizontalAlignment="Center" TextWrapping="Wrap" Text="I need that Row" VerticalAlignment="Center" FontSize="24" TextAlignment="Center" Grid.Row="2"/>
</Grid>
With a Viewbox:
<Viewbox Grid.Row="1" HorizontalAlignment="Center" Stretch="Uniform" StretchDirection="Both">
<Canvas Width="1024" Height="400">
...
</Canvas>
</Viewbox>(You'll probably need to play around with the canvas's height to get the result you want.)

Hello Richard,
first of all thank you for replying. Currently doing comprehensive test of the first variant (with Canvas).
Please share with experience; how to move eg. my sketch, if it's situated within Canvas space.
I asked because I'd failed to move the sketch separately (it moves with Canvas itself only).
Thanks in advance!
P.S. the first feeling. It seems Canvas' variant strongly keeps original (1024x768) position of the controls. With no adaptation/resizing, though. In other words the controls don't "swim", at least. 
To be continued.
Yes, it seems that's it! The ViewBox's variant, in contrast with Canvas' variant, strongly keeps position of the controls and scales them correspondingly to given aspect ratio/resolution.
To be honest, I tried to use symbiosis of Canvas and ViewBox; true, with no success. Because I didn't use some significant (as it turned out) parameters which you offered.
P.P.S. Previously, I asked the same question at many places. I got a strong sense that nobody had got me. What I really need. I provided the same sample code, though. As though the people never faced with such kind of issues. Perhaps they don't port their apps to another workstations or make "Calculator" apps only, or so.
my regards.

To move things around on the canvas, you'll need to update the Canvas.Top and Canvas.Left properties on the things you want to move.
If you want to move a group of shapes as a single unit, the simplest option would probably be to use nested Canvas panels. You can then change the Canvas.Left and Canvas.Top properties on the child canvas to move the entire group.
<Canvas Grid.Row="1">
<Canvas Canvas.Top="..." Canvas.Left="...">
<Path ... />
...
</Canvas>
<Canvas Canvas.Top="..." Canvas.Left="...">
<Path ... />
...
</Canvas>
...
</Canvas>
You'll obviously need to adjust the position of the shapes within the nested canvas, since they'll now be relative to the position of the nested canvas rather than the parent canvas. So if your shape was previously positioned at (100, 50), and is now in a nested canvas positioned at (90, 50), the shape would need to be at (10, 0).
WPF also has strong support for animation:

While playing around "Symbiosis" of ViewBox and Canvas I stumbled across a weird behavior of Canvas.
Eg., both ViewBox and Canvas are (Grid.Row="1"). I've got "Row1" dimensions and made a Canvas (Sketch inside) with exactly same dimensions. Then I put it into a ViewBox. Yes, as I wrote yesterday this "Symbiosis" keeps position and scales controls. That's true.
However, I noticed one weirdness. I colored Canvas and when I maximized window (1920x1080) I had seen that Canvas hadn't overlapped entire width of the window. There were two pretty wide, vertical non-colored "columns", to the left and right of colored Canvas.
P.S. I've tried to play with Canvas' height and width, to no avail. It just disappears, if it has no dimensions.

The Viewbox has Stretch="Uniform". That means it won't change the aspect ratio of the child Canvas.
If you resize the window so that row 1 has an aspect ratio that isn't 256 × 125 (1024 × 500), then you'll end up with spaces around your Viewbox, either on the left and right sides, or on the top and bottom sides.
If you want to fill the entire background of the row, add a Rectangle to the same grid row, outside of the Viewbox, and set your fill there. You'll need to add it to the markup before the Viewbox, so that the rectangle appears behind it.
<Rectangle Grid.Row="1" Fill="Bisque" />
<Viewbox Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center" Stretch="Uniform" StretchDirection="Both">
<Canvas Width="1024" Height="500">
...
</Canvas>
</Viewbox>

I think that the case with rectangle isn't a way.
I need overlapping of entire Row1 by Canvas. Because I'm going to use whole space of Row1, from left to right.
True, I can't figure out what I need to do for that.

I can assure you, it is the way.
Try it and see.

Yes, agree. That's fake way.
There's no canvas at fake colored places.
I need overlapping of entire Row1.

You can't have the canvas maintain its aspect ratio and cover the entire space at the same time.
Either the canvas will be distorted, or there will be spaces around it.
There's nothing "fake" about using a rectangle to fill the background of the row.

You approached it all wrong.
At a minimum, all your "graphics" should have been a "user control".
You've mixed content for 3 rows.
As mentioned, "margins" are for "touching up"; not "layout".
Why "paths" instead of "images"?
None of it makes any sense.

Gerry Schmitz> you approached it all wrong.
OK, these words are just words.
Could you show me correct approaches by means of uploading a working code (as it was done above, in previous posts).
Let's suppose. It'll be "simpliest" task called " how to make Canvas to be fully adaptive/responsive to the range of resolutions e.g. 1024x768 ---> 1920x1080".
Really have no clue how to do that by professional way.
I would be much appreciated.

So I have some FrameworkElements that I want to scale with a ViewBox. This works fine with normal XAML code:
<Viewbox Height="100" Width="100">
<local:InfiniteLoadDiagramBase/>
</Viewbox>
But as soon as I want to join them together and scale them appropriately to the available size I have a problem:
<ItemsControl x:Name="MyItems">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel>
</WrapPanel>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Viewbox Height="100" Width="100" Stretch="UniformToFill">
<ContentControl Content="{Binding}"/>
</Viewbox>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
The ViewBox simply refuses to scale them according to the set size of the ViewBox. Any ideas on how to fix this?

I'm querying 3 tables with Joins:
List<PurchasingEntity> results = null;
IQueryable<PurchasingEntity> query = (from c in db.Companies
join p in db.Projects on c.Id equals p.CompanyId
join j in db.Jobs on p.Id equals j.ProjectId
select new PurchasingEntity
{
CompanyId = c.Id,
CompanyName = c.CompanyName,
ProjectId = p.Id,
ProjectName = p.ProjectName,
ProjectStatusId = p.StatusId.HasValue ? p.StatusId : 0,
JobId = j.Id,
JobNumber = j.JobId,
Phase = j.Phase,
Quantity = j.Quantity.HasValue ? j.Quantity.Value : 0,
StartDate = j.StartDate.HasValue ? j.StartDate : null,
LumberVendorId = j.LumberVendorId,
HardwareVendorId = j.HardwareVendorId,
TrussVendorId = j.TrussVendorId
});
var predicate = PredicateBuilder.True<PurchasingEntity>();
predicate = predicate.And(i => i.ProjectStatusId == awardedId);
if (companyId > 0)
{
predicate = predicate.And(i => i.CompanyId == companyId);
}
if (projectId > 0)
{
predicate = predicate.And(i => i.ProjectId == projectId);
}
if (startDate != null)
{
predicate = predicate.And(i => i.StartDate >= startDate);
}
if (endDate != null)
{
predicate = predicate.And(i => i.StartDate <= endDate);
}
results = query.Where(predicate).ToList();
I doh't want to include an Companies, Projects, or Jobs if they are marked as deleted, which is DeletedDT.HasValue.
The problem is that the PredicateBuilder is working on type PurchasingEntity which is being formed via the join.
How do I filter these out???
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

You'll need to add the filters to the base query:
from c in db.Companies
join p in db.Projects on c.Id equals p.CompanyId
join j in db.Jobs on p.Id equals j.ProjectId
where c.DeletedDT == null && p.DeletedDT == null && j.DeletedDT == null
...
Also, since you're combining all of the filters using And, you don't actually need the predicate builder. Calling Where multiple times will have the same effect.
query = query.Where(i => i.ProjectStatusId == awardedId);
if (companyId > 0)
{
query = query.Where(i => i.CompanyId == companyId);
}
if (projectId > 0)
{
query = query.Where(i => i.ProjectId == projectId);
}
if (startDate != null)
{
query = query.Where(i => i.StartDate >= startDate);
}
if (endDate != null)
{
query = query.Where(i => i.StartDate <= endDate);
}
results = query.ToList();

Here's my link:
<TextBlock Grid.Row="0"
Margin="5">
<Hyperlink x:Name="link">
<TextBlock Text="Purchasing"
FontSize="14"/>
<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<i:InvokeCommandAction Command="{Binding ActionCommand, RelativeSource={RelativeSource AncestorType=Window}}"
CommandParameter="{Binding ElementName=link}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
</Hyperlink>
</TextBlock>
I get
System.Windows.Data Error: 40 : BindingExpression path error: 'ActionCommand' property not found on 'object' ''MainWindowView' (Name='window')'. BindingExpression:Path=ActionCommand; DataItem='MainWindowView' (Name='window'); target element is 'InvokeCommandAction' (HashCode=36783718); target property is 'Command' (type 'ICommand')
It is trying to bind to the VIEW, not the VIEWMODEL. What's wrong here?

Your RelativeSource is set a Window. As WPF allows you to bind to other controls, as well as ViewModels, it makes no assumptions about what you are trying to do so it doesn't automatically try to pick up the DataContext. Try changing this to {Binding DataContext.ActionCommand, RelativeSource={RelativeSource AncestorType=Window}} instead.

That did it. Thank you.
Any thoughts on this? Probably similar but I can't seem to get it right.

I'm adding a context menu to my tabs with "Close", "Close All", and "Close All But This". Heres' the XAML:
<Style TargetType="TabItem">
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu>
<MenuItem Header="Close All"
Command="{Binding DataContext.CloseTabCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type MenuItem}, AncestorLevel=1}}"
CommandParameter="{Binding }"/>
<MenuItem Header="Close All"
Command="{Binding DataContext.CloseAllTabsCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type MenuItem}, AncestorLevel=1}}"
CommandParameter="{Binding }"/>
<MenuItem Header="Close All But This"
Command="{Binding DataContext.CloseAllButThisTabCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type MenuItem}, AncestorLevel=1}}"
CommandParameter="{Binding }"/>
</ContextMenu>
</Setter.Value>
</Setter>
</Style>
The biding isn't work. The commands aren't called. Here's the output window messages:
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.MenuItem', AncestorLevel='1''. BindingExpression:Path=DataContext.CloseTabCommand; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'Command' (type 'ICommand')
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.MenuItem', AncestorLevel='1''. BindingExpression:Path=DataContext.CloseAllTabsCommand; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'Command' (type 'ICommand')

BindingExpression:Path=DataContext.CloseAllButThisTabCommand; DataItem=null; target element is 'MenuItem' (Name=''); target property is 'Command' (type 'ICommand')
What's the right way to bind the menu item's command to the main window's VM?
Thanks

I guess there are ways to solve that. But they are not based on pure XAML.
