Coding Techniques & Coding Standards

                                                     Coding Techniques:

• Inline Coding
• Code Behind

1.Inline Coding:

        It contains both Designer Code & Business Logic in  .aspx page.

2. Code Behind:

•         Designer Code in  .aspx page

•         Business Logic in  .aspx.cs page

What is Designer Code?

                It is  required for designing the UI.

What is Business Logic?

                It is required for executing the logic behind the screen.

                                           Coding Standards of C# Asp.Net:

·         Pascal Casing: - First character of all words are Upper Case and other characters are lower case.(class names, method names)

Ex: BackColor

·         Camel Casing: - First character of all words, except the first word are Upper Case and other characters are lower case.(variable names & method parameters)

Ex: backColor

·         Do not use single character variable names like i, n, s etc. Use names like index, temp

One exception in this case would be variables used for iterations in loops:

for ( int i = 0; i < count; i++ )
{
       ...
}

·         Do not use underscores (_) for local variable names.

·         Namespace names should follow the standard pattern

<company name>.<product name>.<top level module>.<bottom level module>

·         Use appropriate prefix for the UI elements so that you can identify them from the rest of the variables.

a.     Use a common prefix ( ui_ ) for all UI elements. This will help you group all of the UI elements together and easy to access all of them from the intellisense.

b.     Use appropriate prefix for each of the ui element. A brief list is given below. Since .NET has given several controls, you may have to arrive at a complete list of standard prefixes for each of the controls (including third party controls) you are using.

Control	Prefix
Label	lbl
TextBox	txt
DataGrid	dtg
Button	btn
ImageButton	imb
Hyperlink	hlk
DropDownList	ddl
ListBox	lst
DataList	dtl
Repeater	rep
Checkbox	chk
CheckBoxList	cbl
RadioButton	rdo
RadioButtonList	rbl
Image	img
Panel	pnl
PlaceHolder	phd
Table	tbl
Validators	val

·         File name should match with class name.

For example, for the class HelloWorld, the file name should be helloworld.cs (or, helloworld.vb)

·         Use Pascal Case for file names.
