Background

EXtensible Application Markup Language (XAML) which is pronounced as Zamel is Microsoft's new markup language to define dynamic or static user interfaces for .NET applications. XAML will be used in Windows Vista to design user interfaces, but can be applied to Windows XP or Windows 2003 as well.

XAML comes to separate the UI code from application logic code and is very similar to MVC. XAML is tied to Windows Presentation foundation (codenamed Avalon) to build a whole user interface in .NET 3.0 and Windows Vista.

XAML is an XML child indeed. Every XAML code must be a well-formed XML file and XAML inherits all XML definitions and rules. We can consider it as the last part of a chain that contains HTML, XHTML and other markup languages for UI.

What makes XAML different from other XML children is what it represents. Every XAML element represents a .NET CLR class. This lets you to extend and work on XAML easily.

The model that XAML in conjunction with Windows Presentation Foundation provides to let developers design a rich user interface is similar to code behind and code inline model in ASP.NET.

This means you can put your application logic in a separate file or embed it inline in XAML file itself.

XAML files will be compiled to BAML files. The advantage of BAML is it is smaller than XAML and is easier to read so it is faster to load.

Title: How to add rows programmatically!

OK, I found out, it was actually adding correctly, it was just that the container shrimped the grid so all rows became too narrow. I put the grid into a scroll container, and - voilá !

Just to make it clear: the label, labelEnglish and textBox are labels and textbox that are created and set content on before the code you see.

I want to be able to add lables and text boxes to the grid content programmatically. How do I do that? I tried with the following code, but it doesn't seem to work. grid (with lowercase g) is the grid object I am working with. Grid (with uppercase G) lets me run the static methods to set column and row number (I didn't find any other way to do this).

grid.RowDefinitions.Add(new RowDefinition());
grid.Children.Add(label);
Grid.SetColumn(label, 0);
Grid.SetRow(label, grid.RowDefinitions.Count - 1);
grid.Children.Add(labelEnglish);
Grid.SetColumn(labelEnglish, 1);
Grid.SetRow(labelEnglish, grid.RowDefinitions.Count - 1);
grid.Children.Add(textBox);
Grid.SetColumn(textBox, 2);
Grid.SetRow(textBox, grid.RowDefinitions.Count - 1);
