ViewModel Method Not Reloading View

I have a problem with Xamarin.Forms whereby the View is not refreshing as I would expect it to.
I have bound a View to a ViewModel, and I have a series of methods to perform various functions.
On the successful completion of a function, I want it to execute my LoadResults() method.
The LoadResults() method works fine when I load the view initially. However, when I execute any other method (DeleteScan(id) method shown below) it should re-fire the LoadResults() method and reload the page.
I know it is entering the LoadResults() method as I've put a break point in there and stepped through it. But by the end of it, it doesn't reload the view.
I also know the view can refresh, as I have other simple methods which are simply updating properties in the VM and those changes are reflecting in the UI.
So for whatever reason, LoadResults() is not reloading the page.
Any ideas what I've done wrong here?

Network Map with full detail and hierarchy

I wrote a piece of code to run from the first IP address to the last and retrieve the MAC and Hostname of devices in my network.
But, i do not know how to get the hierachy of then. Information like what router is the device conected (via Cable of WiFi also). And some routers are not managed (they don't have IP - they are just "switchs").
First, i didn't think it was possible, since a "tracert" on the CMD does not show then, but when i call the "Network Complete Map" on Windows Control Panel, they get all the information i need - so there is a way. See the image below:
The "switchs" circled in red have no IP, the "TL-xxxx" are routers with DHCP turned of. The "gateway" is a server that has the DHCP and provides connection to the internet.
Thus far, i wrote the following code:

Kruskal's Maze Algorithm - Only Working up to dimension 11x11

I am using https://courses.cs.washington.edu/courses/cse326/07su/prj2/kruskal.html psuedocode as reference when writing my code.
Code is in C#, and my code can only generate mazes up to 11x11, anything more than than it will run, seemingly, forever (e.g. 12x11 or 12x12 won't work)
Grid Properties are just storing the dimension of the size of the maze
public class GridProperties
{
private int xLength;
private int yLength;
public GridProperties(int xlength, int ylength)
{
xLength = xlength;
yLength = ylength;
}
public int getXLength()
{
return this.xLength;
}
public int getYLength()
{
return this.yLength;
}

Since I got you guys here, please don't mind pitching in what I can improve on as in coding style and other things that you are displeased with.
Thanks in advance.

Error seems to be here:
this.updatePassageID(this.xCoord.ToString() + this.yCoord.ToString());
Image those two scenarios:
xCoord = 1 and yCoord = 11.
xCoord = 11 and yCoord = 1.
both those result in newPassageID of 111.
So simply change the line to
this.updatePassageID(this.xCoord.ToString() + "|" + this.yCoord.ToString());
or written more sexy:
this.updatePassageID($"{xCoord}|{yCoord}");
With this you will receive
1|11 for the first scenario and 11|1 for the second which differs.
Edit based on comments:
I saw that your code is looping endlessly in the method createMaze. This method calls a method called checkForDifferentPassageID in there you check if two collections are equal or not. Once I saw that those collections are of type HashSet<string>, I thought that maybe your strings you put into the HashSet arent as unique as you think they are and there we go. So overall it took me like 10 minutes.

I have to write if-else Statements in a Domain-Specific-Language which is really a pain in the ass!
(The DSL is from a Third-Party-Tool which I have to use to generate WHERE-Statements for SQL-Queries)
Syntax:
#IF(#ISEMPTY(#SUB(temp.last_name))),'if true','else')
#SUB() reads a textboxvalue
Sample:
#IF(#ISEMPTY(#SUB(temp.last_name))),'','account_contact.last_name = ''DOE'' ')
you have to double your single-quotes in the else statement and if you want to nest different "if-else" every time you go a level deeper you have to double the doubled single-quotes!
You see it´s not very simple to write if you have complicated contitions...
So I thought I write a parser that transforms a normal if-else statement to this DSL-Syntax!
The Parser should create objects of this class:
public class IfCondition
{
public int ID { get; set; }
public int ParentID { get; set; }
public int Level { get; set; }
public string Condition { get; set; }
public string Content { get; set; }
public string ElseContent { get; set; }
}
based on a Collection of this Objects I could generate the DSL-Statements!
So my Problem is I really don´t have a clue, how to parse a String like this:
IF(#ISEMPTY(#SUB(temp.last_name))) { }
ELSE
{
IF(#SUB(temp.test) = 'Y')
{
account_contact.last_name = 'DOE'
}
ELSE
{
account_contat.first_name = "JOHN"
}
}
can somebody give me a nudge in the right direction?

If you use Roslyn for syntax rewritting. Not to just write about what you can do, here is an easy example.
Basically how it works. You create a syntax tree for your code and then use predefined visitors to visit those nodes you want to rewrite, you replace them by valid C# code and then you can compile this tree and make it work.
EDIT:
Another, more reliable source with an example

Serialization Command:

{
get
{
return new RelayCommand(delegate
{
OpenFileDialog openDialogue = new OpenFileDialog()
{
AddExtension = true,
CheckPathExists = true,
CheckFileExists = true,
DefaultExt = ".p51",
Filter = "Climate Files|*.p51",

if ((bool)openDialogue.ShowDialog())
{
string filePath = String.Empty;
try
{
filePath = openDialogue.FileName;
var climate = new Climate();
climate.FilePath = filePath;
var savePath = String.Format("{0}\\{1}.p51x", ClimateDataPath, Path.GetFileNameWithoutExtension(filePath));
climate.FileData.SaveP51XFile(savePath);
}
catch (Exception e)
{
MessageBox.Show(String.Format("The file \"{0}\" could not be opened, {1}", filePath, ExceptionUtilities.JoinExceptionMessages(e)), "Invalid File");
}
}
});
}
}
When executing ImportP51, I get the exception "Specified method is not supported", I am using protobuf-net V2 r594 which was released on the 12/10/2012 and am thinking of trying to use one of the previous versions if I cannot get it to work with this version. Can someone please tell me what I am doing wrong?

I've tried to reconstruct a working version of the code (since I don't have your BaseModel) which I've done by using automatically implemented properties and adding an initializer for the list (DailyData), and explicitly referencing r594 from google-code. The only error I get is:
Cannot apply changes to property ClimateDailyData.JulianDay
which makes sense, because it can't rightly deserialize data into a read-only property, so I removed the serialization marker from that one:
// [ProtoMember(2)] removed - serialized implicitly via DataData
public int JulianDay { get { return DataDate.DayOfYear; } }
After that it worked fine. Since I don't have your command framework, I have:
static class Program
{
static void Main()
{
var climateFile = new ClimateFile();
climateFile.InitSomeDataForSerialization();
climateFile.SaveP51XFile("foo.P51X");
var clone = ClimateFile.Load("foo.P51X");
}
}
where InitSomeDataForSerialization just sets some of the values (since they have private setters, I can't do that in Main):
public void InitSomeDataForSerialization()
{
Longitude = 10; Latitude = 4; Notes = "Test";
DailyData.Add(
new ClimateDailyData { DataDate = DateTime.Today, MinTemperature = 12, MaxTemperature = 35}
);
}
And... it works.
On a hunch, I checked what happens if you reference "CoreOnly" instead of "Full", but that then refuses to compile because Serializer.Serialize<T> and Serializer.Deserialize<T> don't exist.
I'm happy to help, but as far as I can tell, nothing is wrong.
Things I would suggest next:
show the full stack-trace of what happens in this exception, including any inner-exceptions (see the fix below)
please check exactly which file you referenced in the 594 zip (look at "What Files Do I Need.txt", but I'd guess the correct one for you is "Full/net30/..."; the nuget package configures the most appropriate files automatically)
please show a fully reproducible example, i.e. where I can press F5 and see the exact exception (I had to change the code in the example for it to compile, which means I am no longer testing the same thing)
Fix for correct exception wrapping:
catch (Exception e)
{
throw new InvalidDataException(String.Format("The file \"{0}\" could not be opened", filePath), e);
}
