In MVVM you need that your UI will not contain and business logic, and have a class which is a ViewModel which will do all the business logic.

You need to set the dataconext of your UI to point the viewmodel you want.

MVVM stands for Model-View-ViewModel.
3 layes where the UI doesn't know much about the ViewModel and nothing about the model (there are some cases where we can have the UI know about some properties for the model), the Model doesn't know about the ViewModel, and the ViewModel doesn't know about the UI.


You should better start with a small application before you try to do something more complicated.
What kind of example would you like to build?

I would like to continue building my app that draws Polygons.
Right now code here draws only 1st Polygon and it's hardcoded. So, I want to use MVVM and draw the rest of the Polygons from coordinates saved in listPointsLine1 and listPointsLine2.

Here is XAML:

Meanwhile I will try to mess with this myself using that WpfExample1 you sent me earlier.

 Thank you Guru Saragani!  Looking forward to hear from you! :)))

Ok, MVVM means Binding.
Binding means that UI need to get pontificated about property changes. The way the UI does it with it's own properties is Dependency Properties, which is an class of Microsoft.

The way we are doing to do it in our classes would be INotifyPropertyChanged, which is an interface for notifying that something got changed.

To reduce the need to implement that interface over and over again. We will call this calls ViewModelBase:

    /// <summary>
    /// Provides common functionality for ViewModel classes
    /// </summary>
    /// 
    public abstract class ViewModelBase : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        protected void OnPropertyChanged(string propertyName)
        {
            PropertyChangedEventHandler handler = PropertyChanged;

            if (handler != null)
            {
                handler(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }

Open in new window



Now let's take a look on how to define a property in one of your classes...

Let's assume that the class is called MainViewModel... so:

public class MainViewModel : ViewModelBase
{
    private string _name;
   
    public string Name
    {
        get
        {
            return _name;
        }
        set
        {
            _name = value;
           OnPropertyChanged("Name");
        }
    }
}

The bold text is the most important thing... this is how we notify the UI that the property called Name got changed.


Now we need to define the DataContext of our UI.
There are several ways to do it. The easiest way is by:
1) this.DataContext = new MainViewModel();
Put this line after the InitializeCompenents();

This method is not alway good since on some cases we don't want the data context to be a new instance but an existing one.


That method is called View First... cause we have defined a View and then gave it a ViewModel/DataContext.


Another way is ViewModel First... which in this case we have a some kind of Content Presenter (or content control) which is bound to some ViewModel, and by defining a DataTemplate we tell out application what UI to show...
For example, we have a ListBox with items that derive from Animal
I would like to show a picture of a cow if the item is a cow, and play a movie of a walking dog in case the animal is a dog.

I forgot to mention that in your ViewModels you don't work with List, but with ObservableCollection, since this collection has a feature that can notify the UI that items were added, removed, or whole collection was cleared.

Hi Saragani, I am getting many reference errors after I added these classes to my project. Could you zip working version of this solution and email to me? vadymgpr@yahoo.com Thank you!

Ignore my previous comment. I think I got it. Where is this image folder suppose to be in my project?

 ImageSource="/SliderScaleCanvas;component/Images/GasPattern.jpg"
Commented:
I just sent it to you. If you still have a problem then tell me.

Commented:
Saragani, it’s AWESOME! I accept this as solution! :)))

What I would like to do next with this app is to read Points from SQL Server DB with WCF.

Do you have WCF experience? I am going to open a new question in WCF section to continue with this project. Also I need to come up with design for the DB Table to hold my Points data. May be you can help with this as well?

Thanks a lot! :)))

Excellent guidance and help from Saragani! Short and straight to the point.  Easy to understand and follow. Very nice! :)))

Commented:
I know nothing about WCF

Hi Saragani, I have created root folder Images in my old project with GasPattern.jpg file. I build solution without errors. But when I run it I get an exception. It can not locate this image path:

<ImageBrush TileMode="Tile" Viewport="0, 0, 20, 20" Stretch="None" ViewportUnits="Absolute" ImageSource="/SliderScaleCanvas;component/Images/GasPattern.jpg" />

Why?

Commented:
The image must be defined (properties) as "never copy" and as a resource.

Author

Commented:
OK, Thanks!

Saragani, here is my new post regarding WCF for this project. Lets continue there if you can help me:

It's not about WCF. Ok, I post it here:
Please take a look at my initial prototype app SquigglyLines (attached to my email).
 
As you see it outlines Polygon created by Points between 4 lines. The number of Lines may vary. But we assume that they are always one above another. Area between 2 points on the one line and 2 points on the other line is Polygon. Polygons are stacked one on the top of each other.
 
  I need my application to be smart enough to draw these Polygons properly. Initially I thought to use Array or List (like you suggested) to insert new Points in the middle of it because of how geometry class draws them.
 
If I add another Lines to your example:
 
List<Point> listPointsLine3 = new List<Point>(new Point[] { new Point(100, 300), new Point(200, 350), new Point(300, 450), new Point(400, 400), new Point(500, 300), new Point(600, 350), new Point(700, 450), new Point(800, 400), new Point(900, 450), new Point(1000, 500) });
 
List<Point> listPointsLine4 = new List<Point>(new Point[] { new Point(100, 550), new Point(200, 600), new Point(300, 700), new Point(400, 650), new Point(500, 550), new Point(600, 600), new Point(700, 700), new Point(800, 650), new Point(900, 700), new Point(1000, 750) });
 
........................
 
// 3rd Line Points
inBoundsPoitns = from val in listPointsLine3
where val.X <= 10 * RegionWidthPercentage
orderby val.X descending
select val;
 
points.AddRange(inBoundsPoitns);
 
// 4th Line Points
inBoundsPoitns = from val in listPointsLine4
where val.X <= 10 * RegionWidthPercentage
orderby val.X descending
select val;
 
points.AddRange(inBoundsPoitns);
 
 Polygons are drawn not correctly (not like in my hardcoded prototype).
 
...........................................
 
So, the pattern is:
 
Suppose we have 3 lines. Each line has 4 Points.
   Line1 = Points(1,2,3,4)
   Line2 = Points(5,6,7,8)
   Line3 = Points(9,10,11,12)
 
So we have 6 polygons between these points:
   
                           1---2---3---4
                           |   |   |   |
                           5---6---7---8
                           |   |   |   |
                           9--10--11--12
 
If I display 10% of the Canvas and Points 1,2,5,6,9,10 in it then:
 
   Polygon1 = Points(1,2,6,5)   <- Draw 1st top left Polygon
   Polygon2 = Points(5,6,10,9)  <- 2nd Polygon under 1st one
 
Next, 20% of the Canvas:
   
   Polygon1 = Points(1,2,  3,7   6,5)   <- Draw 1st top left Polygon
   (3 and 7 are new Points inserted in the middle of List<Points>)
 
   Polygon2 = Points(5,6,  7,11  10,9)  <- 2nd Polygon under 1st one
   (7 and 11 are new Points inserted in the middle of List<Points>)
 
and so on...
 
 Also, this XAML needs to be changed to allow more then one Polygon area and different ImageBrushes:
 
<Polygon Points="{Binding PolygonPoints, Converter={StaticResource pointsCollectionConverter}}">
<Polygon.Fill>
<ImageBrush TileMode="Tile" Viewport="0, 0, 20, 20" Stretch="None" ViewportUnits="Absolute" ImageSource="/SliderScaleCanvas;component/Images/GasPattern.jpg" />
</Polygon.Fill>
</Polygon>
 
What are your thoughts? It more tought then I thought :\  Thank you for all your help! :)))

Do not worry about this code:
      // Move all polygons up & left 
            TranslateTransform translateTransform1 = new TranslateTransform(-300, -100);

            Pol1.RenderTransform = translateTransform1;
            Pol2.RenderTransform = translateTransform1;
            Pol3.RenderTransform = translateTransform1;

            // Make all polygons smaller
            ScaleTransform scaleTransform1 = new ScaleTransform(0.8, 0.8);

            Pol1.RenderTransform = scaleTransform1;
            Pol2.RenderTransform = scaleTransform1;
            Pol3.RenderTransform = scaleTransform1;

Hi, what is the point of having 2 polygons while in drawing you see one?
(both polygons have 1 common line)

Lets take for example 2 squares, 1 above the other, they will look like 1 big square

Author

Commented:
Yes, you are right.
But each square represent a different slice of data. One Polygon is on top of the other and they have common border, common Points. But they can have different size (or same size, doesn’t matter) and should be painted in different colors. Same like multi-layered cake slice.

Author

Commented:
All polygons between two adjacent lines should be painted same color (pattern):
_____________________________________________
   RED

   BLUE

How to have more that 1 polygon without having to define in hardcode Xaml a specific number of polygons?

Author

Commented:
Yes, how to have more that 1 polygon without having to define in hardcode Xaml a specific number of polygons?
And, how to modify your app so I can add more lines like:

List<Point> listPointsLine3 = new List<Point>(new Point[] { new Point(100, 300), new Point(200, 350), new Point(300, 450), new Point(400, 400), new Point(500, 300), new Point(600, 350), new Point(700, 450), new Point(800, 400), new Point(900, 450), new Point(1000, 500) });
 
List<Point> listPointsLine4 = new List<Point>(new Point[] { new Point(100, 550), new Point(200, 600), new Point(300, 700), new Point(400, 650), new Point(500, 550), new Point(600, 600), new Point(700, 700), new Point(800, 650), new Point(900, 700), new Point(1000, 750) });

The problem is that app not outlines Polygons correctly. Compare what my static demo draws and your app.

Commented:
In 1 word: ItemsControl

In 31 words: a polygon viewmodel with a collection of points, while having your mainViewModel have a collection of polygonViewModel. Then the UI has an ItemsControl bound to that collection with Canvas as ItemsPanel.

Commented:
Why isn't it outline it correctly?
What do you mean by outline?

Author

Commented:
OK, run my static sample. It drraws 3 areas of Polygons with different colors.
Now, add 2 new points to your app:

List<Point> listPointsLine3 = new List<Point>(new Point[] { new Point(100, 300), new Point(200, 350), new Point(300, 450), new Point(400, 400), new Point(500, 300), new Point(600, 350), new Point(700, 450), new Point(800, 400), new Point(900, 450), new Point(1000, 500) });
 
List<Point> listPointsLine4 = new List<Point>(new Point[] { new Point(100, 550), new Point(200, 600), new Point(300, 700), new Point(400, 650), new Point(500, 550), new Point(600, 600), new Point(700, 700), new Point(800, 650), new Point(900, 700), new Point(1000, 750) });fenter

Forget about different colors, just see how Polygons are drawn compared to my demo. Sequence of Points is incorrect.  If you have 4 Points which are form square then they should be drawn sequentially:
1,2,3,4. Right? If you draw them like 1,2,4,3 then you will get a wierd X shape Polygon.

          1-------------2      That's what you get drawing in sequence 1,2,4,3 instead of square.

I've sent you a new sample project that demonstrates what you have requested.
Again, it is fairly easy...

If I would show you things that we do at work with WPF, I believe that yours and other peoples tongue  will fall to the ground... :-)

Commented:
Saragani, your app works fine!

This was happening because I sorted  3rd Line Points descending instead of ascending. Needs to be:

    // 3rd Line Points
            inBoundsPoitns = from val in listPointsLine3
                             where val.X <= 10 * RegionWidthPercentage
                             orderby val.X ascending
                             select val;

            points.AddRange(inBoundsPoitns);

Sorry, my bad :\

Now, how to use different image brushes (patterns) for each area between adjacent lines:
_____________________________________________
   RED
_____________________________________________
   BLUE
_____________________________________________
   GREEN
....................................................... and so on............  ???

My example shows how to have a different brush for each polygon. In my case I use the index I iterate in order to get an image (using switch).

I don't know your logic, but maybe the data that comes from the database should also contain the type of the data (so it will give it a color by type).

Or you can do like by, by index.

Thank you! This one ROCKS! :)))

If coordinates of my data expect X=0 and Y=0 to be at the left bottom corner of the Canvas. How to change Canvas coordinate system?

How to make my window tranparent but with chrome around? (I did it by using styles for my static demo, but may be you know better way?)

You said that you don't really know WCF. I thought WCF is the best way to get data from database.

How do you read your data?

Hi Saragani! Thank you for the flip Canvas coordinates example!

Man, I feel so dumb looking at your app :(  I still do not understend how some of it works :\\\  MVVM is very different from ASP.NET.

What about this my question:
                                 
                                   How to make Window tranparent but with chrome around?
                                   I've done it by using styles in my static demo, but may be you know the better way?

I don't know what exactly you mean since I haven't seen your original code, since on your post (http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_27035490.html) you did not post the window's XAML, just it's content.

What do you mean transparent but with chrome around?

Can you show me a print-screen of what you mean (maybe from your original program)?

Unfortunately, you cannot have both Window Chrome and allowtransparency=true together.
Your way looks fine.

I only have close button "X" on my transparent chrome.

                How to add minimize and restore buttons? To make it look like browser window.
                What commands should I use for these buttons?

Thank you! :)

Hey Saragani,
Here is range slider example:

http://www.thejoyofcode.com/Creating_a_Range_Slider_in_WPF_and_other_cool_tips_and_tricks_for_UserControls_.aspx

What is your opinion? Is it a good solution or you know a better way to accomplish this?

I want to implement range slider in my app. If user wants to see the slice of the Canvas in the range between choosen percents:
                      |-----hidden--------| | polygons to show | |-----------------hidden-------------------|                            
                      0%                     30%                          60%                                                 100%

Thank you!
