Formatting specifiers

Numbers
Basic number formatting specifiers:

Specifier Type Format Output (Passed Double 1.42) Output (Passed Int -12400)
c Currency {0:c} $1.42 -$12,400
d Decimal (Whole number) {0:d} System.FormatException -12400
e Scientific {0:e} 1.420000e+000 -1.240000e+004
f Fixed point {0:f} 1.42 -12400.00
g General {0:g} 1.42 -12400
n Number with commas for thousands {0:n} 1.42 -12,400
r Round trippable {0:r} 1.42 System.FormatException
x Hexadecimal {0:x4} System.FormatException cf90
Custom number formatting:

Specifier Type Example Output (Passed Double 1500.42) Note
0 Zero placeholder {0:00.0000} 1500.4200 Pads with zeroes.
# Digit placeholder {0:(#).##} (1500).42
. Decimal point {0:0.0} 1500.4
, Thousand separator {0:0,0} 1,500 Must be between two zeroes.
,. Number scaling {0:0,.} 2 Comma adjacent to Period scales by 1000.
% Percent {0:0%} 150042% Multiplies by 100, adds % sign.
e Exponent placeholder {0:00e+0} 15e+2 Many exponent formats available.
; Group separator see below
The group separator is especially useful for formatting currency values which require that negative values be enclosed in parentheses. This currency formatting example at the bottom of this document makes it obvious:

Dates
Note that date formatting is especially dependant on the system’s regional settings; the example strings here are from my local locale.

Specifier Type Example (Passed System.DateTime.Now)
d Short date 10/12/2002
D Long date December 10, 2002
t Short time 10:11 PM
T Long time 10:11:29 PM
f Full date & time December 10, 2002 10:11 PM
F Full date & time (long) December 10, 2002 10:11:29 PM
g Default date & time 10/12/2002 10:11 PM
G Default date & time (long) 10/12/2002 10:11:29 PM
M Month day pattern December 10
r RFC1123 date string Tue, 10 Dec 2002 22:11:29 GMT
s Sortable date string 2002-12-10T22:11:29
u Universal sortable, local time 2002-12-10 22:13:50Z
U Universal sortable, GMT December 11, 2002 3:13:50 AM
Y Year month pattern December, 2002
The ‘U’ specifier seems broken; that string certainly isn’t sortable.

Custom date formatting:

Specifier Type Example Example Output
dd Day {0:dd} 10
ddd Day name {0:ddd} Tue
dddd Full day name {0:dddd} Tuesday
f, ff, … Second fractions {0:fff} 932
gg, … Era {0:gg} A.D.
hh 2 digit hour {0:hh} 10
HH 2 digit hour, 24hr format {0:HH} 22
mm Minute 00-59 {0:mm} 38
MM Month 01-12 {0:MM} 12
MMM Month abbreviation {0:MMM} Dec
MMMM Full month name {0:MMMM} December
ss Seconds 00-59 {0:ss} 46
tt AM or PM {0:tt} PM
yy Year, 2 digits {0:yy} 02
yyyy Year {0:yyyy} 2002
zz Timezone offset, 2 digits {0:zz} -05
zzz Full timezone offset {0:zzz} -05:00
: Separator {0:hh:mm:ss} 10:43:20
/ Separator {0:dd/MM/yyyy} 10/12/2002
Enumerations
Specifier Type
g Default (Flag names if available, otherwise decimal)
f Flags always
d Integer always
x Eight digit hex.
Some Useful Examples
String.Format(”{0:$#,##0.00;($#,##0.00);Zero}”, value);

This will output “$1,240.00″ if passed 1243.50. It will output the same format but in parentheses if the number is negative, and will output the string “Zero” if the number is zero.

String.Format(”{0:(###) ###-####}”, 8005551212);

This will output “(800) 555-1212″.

Convert Numbers with 2 decimal places in GridView Field

If you are using template field in GridView
use
Text='<%# Bind("Project_cost", "{0:N}") %>'
in itemTemplate of that field
it will automatically convert your number field with 2 decimal places

If you are using boundField and wants to doing same
use
DataFormatString="{0:N}"

in that boundField it will automatically convert your number field with 2 decimal places

Convert Numbers with 2 decimal places in gridview Template field

Note:

if you are using template field in gridview and wants to convert number field in decimal places(2 and more places) just use Text='<%# Bind("Project_cost", "{0:N}") %>' in itemTemplate field.
It will convert your field values with 2 decimal places
like : your number is -44
after converting - 44.00


Same thing if you want to do with bound field use DataFormatString="{0:N}" in the required field

Usage of doPostBack in a real environment

input type="text" name="t1" id="Tx1" onserverchange="Text1_ServerChange" runat="server" onblur="enablePostBack();"

input type="text" name="t2" id="Tx2" runat="server"

//script for postbacking
script language="javascript"
function enablePostBack()
{
//T1 is the first argument(name of our control) I mentioned earlier and give the
// value of second argument as "" that's all
__doPostBack("Tx1","");
}
/script

//c# functon

protected void Text1_ServerChange(object sender, EventArgs e)
{
Tx2.Value = (Int16.Parse(Tx1.Value) * 45).ToString();
}

How to create runtime click event on runtime button in asp.net?

protected void Page_Load(object sender, EventArgs e)

{

tb = new TextBox();

btn = new Button();

form1.Controls.Add(tb);

form1.Controls.Add(btn);

btn.Text = "Save";

btn.Click += new EventHandler(btn_click);//generating Event

}

protected void btn_click(object sender, EventArgs e)

{

tb.Text = "hello";

}

Calling Web services Through JavaScript/html

//this is your web method
[WebMethod]
public string HelloWorld() {
return "Hello World";
}


//Now use this html code to call web method use head tag for javascript



function InitializeService()
{

Myservice.useService("http://localhost:4765/WebServices/Service.asmx?wsdl", "MyMethod");
//you can use anything in the place of MyMethod
}
function tst(){
//alert('hi');
Myservice. MyMethod.callService("HelloWorld");
//if your web service contains some parameters then set parameters after function name like //("HelloWorld","1","admin")
}
functionShowResult(){
alert(event.result.value);
//Myservice.innerHTML= "Resultado : " + event.result.value;
}


// then on body onload write code
onload="InitializeService()" onresult="ShowResult()"

form id="form1" method="post"
// call javascript function on button click

button onclick="tst()" id="Button1">Call Add Web Method
//use htc file
div id="Myservice" style="behavior:url(webservice.htc)"



Note:
Friends Calling Web Services is a biggest problem with as , I found the logic behind it and I want to share.
First of all we should have a HTC file (U can download from
http://sites.google.com/site/santo01org/javascript-and-web-service
) which is nothing just a HTML file with the complete information of XML http and javascript( a common file for all)Then use the above JavaScript in call page and see the magic.

Best of Luck

disable the back button for All browsers
