CodeBehind vs CodeFile

CodeBehind
Needs to be compiled and the compiled binary is placed in the bin folder of the website.

<%@ Page Title="" Language="C#" MasterPageFile="~/YourMasterPage.Master" AutoEventWireup="true" CodeBehind="YourFile.aspx.cs" Inherits="YourPage" %>

CodeFile
You provide the source file with the solution for deployment and .NET compiles the code when needed.

<%@ Page Title="" Language="C#" MasterPageFile="~/YourMasterPage.Master" AutoEventWireup="true" CodeFile="YourFile.aspx.cs" Inherits="YourPage" %>

Tab Between Fields With Virtual Keyboard

If you have multiple TextBox controls on you screen, you might want the user to just press the enter key on the virtual keyboard to tab between them. To do this. you need to capture the KeyDown event of the control as follows:

<TextBox x:Name="TextBox1" InputScope="Text" KeyDown="TextBox1_KeyDown"/>
<TextBox x:Name="TextBox2" InputScope="Text" KeyDown="TextBox2_KeyDown"/>
<TextBox x:Name="TextBox3" InputScope="Text"/>

Now in the code behind file you can handle the navigation as follows:

private void TextBox1_KeyDown(object sender, KeyEventArgs e)
{
    if(e.Key.Equals(Key.Enter))
    {
        TextBox2.Focus();
    }
}

private void TextBox2_KeyDown(object sender, KeyEventArgs e)
{
    if(e.Key.Equals(Key.Enter))
    {
        TextBox3.Focus();
    }
}
