If your Xaml stream doesn’t load, chances are:

• Your Xaml reference isn’t pointing correctly to the Xaml file.
• Your Xaml is not valid.
• Your Control is not set to be an Embedded Resource.
• InitilazeFromXaml(…) is not in the lowest controls’ contructor in your inheritance tree.

Just a reminder to myself.

• Something is wrong with the names
• You are trying to add the Frameworkelment as a child, but it’s already a child of someone else, and you haven’t removed it.
• It’s null.

Got into a tricky situation today.

I used the new C# Object Initializer “syntactic sugar” to initialize my object:
MyType MyObject = new MyType{MyBool=true};

At the same time I used the property as a condition in MyObject.

First I used it in the constructor, but it didn’t work since the new value of the property was given only after the constructor ran (pretty logical).

Then I used it in the Loaded Event, but the event fires way after I need the changes made by MyBool.

Three things learned:

• The Object Initializer give value to the properties after the object is instantiated.
• I thought the Loaded event fires right after the object is instantiated. It’s not.
• I’m still a Noob.

(The solution was to give parameters to my constructor and give value to the property through it. But this is not the important part.)

Point class constructor problems can be caused by regional settings. Dot vs. comma stuff: http://silverlight.net/forums/t/4142.aspx

I’m still hopeless!!!

Solution 1
Can’t really call it a solution. Just inverses the problem..

double x = Convert.ToDouble("11,5");
double y = Convert.ToDouble("0,44");
Point TestPoint = new Point(x,y);

Solution 2
Didn’t really work for me either. I guess it’s my fault, but i had problem with constructing Point from results of calculations:

Solution 3
My solution. It’s cool until you use it to create a new point. But as you try to give value to a Point property, like GradientOrigin it fails.

double x;
string _x = (2.0 / 3.0).ToString(System.Globalization.CultureInfo.InvariantCulture);
x = double.Parse(_x, System.Globalization.CultureInfo.InvariantCulture);
double y;
string _y = (1.0 / 2.0).ToString(System.Globalization.CultureInfo.InvariantCulture);
y = double.Parse(_y, System.Globalization.CultureInfo.InvariantCulture);
Point TestPoint = new Point(x,y);
