Follow these steps

Step 1: Add one column field in DataTable
Retrieve Data from database and add one column in this datatable using asp.net and increament it by 1.
Suppose you have 100 records so that field values should be 1 to 100

Step 2:Set property
Create three properties CurrentPage, PageSize and PageCount
PageCount is total number of record
PageSize to display number of record on page
CurrentPage is PageIndex

Set these three properties value on page load event after retrieving data from database and add column field in this datatable

Step 3:Take two link Button
Take Previous and Next Link button

Step 4:Get record from DataTable and bind asp table
Before calling this,you must add one column field in datatable so you can get number of record
Suppose,You have 100 record and you have set pagesize 10
first time CurrentPage should be 1
You can get 1 to 10 record from datatable by using select method of datatable
Suppose you add one column with ID,then your code looks like this

you can get "to" to "from" value by this

int t=(CurrentPage-1)*PageSize; // (1-1)*10=0
int f=CurrentPage*PageSize+1; 1*10+1=11
DataRow[] dRow=dataTable.Select("ID>"+t+" and ID<"+f);// dataTable is your DataTable object

the Above line will return you first ten record,you can bind your asp table with these 10 records

step 5: On Next Link Button event
On Next Button event, increament CurrentPage
Suppose at first time you click on Next Button,CurrentPage increament by 1.
now currentPage is 2

calculate again "to" to "from" value

int t=(CurrentPage-1)*PageSize; // (2-1)*10=10
int f=CurrentPage*PageSize+1; 2*10+1=21
DataRow[] dRow=dataTable.Select("ID>"+t+" and ID<"+f);//dataTable is your DataTable object

you can loop through DataRow array and get value from it and bind your asp table

the Above line will return you second 11 to 20 records

Now check here

if PageCount/PageSize is less then currentpage then disable next link button
Suppose you have 99 records your current page 10 then it display 90 to 99 records.Next you have not record so it should be disbled.

Step 6:On previous link button
at first time, when CurrentPage is 1,Privous button link should be disabled.
Same thing here.you have to decrease CurrentPage and process will be same

Note : Store current page in ViewState so you can get it from it other wise it will set default.

I hope this will help you
best of luck

Hi friends,

I am familiar in Asp.net. I have a php script code for flash uploading. I need to convert this php script to java script. For ur's reference i put the code below,

include("JSON.php");
$result = array();

if (isset($_FILES['photoupload']) )
{
$file = $_FILES['photoupload']['tmp_name'];
$error = false;
$size = false;

if (!is_uploaded_file($file) || ($_FILES['photoupload']['size'] > 2 * 1024 * 1024) )
{
$error = 'Please upload only files smaller than 2Mb!';
}
elseif (!$error && !($size = @getimagesize($file) ) )
{
$error = 'Please upload only images, no other files are supported.';
}
elseif (!$error && !in_array($size[2], array(1, 2, 3, 7, 8) ) )
{
$error = 'Please upload only images of type JPEG.';
}
elseif (!$error && ($size[0] < 25) || ($size[1] < 25))
{
$error = 'Please upload an image bigger than 25px.';
}
else {
move_uploaded_file($_FILES['photoupload']['tmp_name'], "./uploadedfiles/".$_FILES['photoupload']['name']);
chmod("./uploadedfiles/".$_FILES['photoupload']['name'], 0777);
}

$addr = gethostbyaddr($_SERVER['REMOTE_ADDR']);

$log = fopen('script.log', 'a');
fputs($log, ($error ? 'FAILED' : 'SUCCESS') . ' - ' . preg_replace('/^[^.]+/', '***', $addr) . ": {$_FILES['photoupload']['name']} - {$_FILES['photoupload']['size']} byte\n" );
fclose($log);

if ($error)
{
$result['result'] = 'failed';
$result['error'] = $error;
}
else
{
$result['result'] = 'success';
$result['size'] = "Uploaded an image ({$size['mime']}) with {$size[0]}px/{$size[1]}px.";
}

}
else
{
$result['result'] = 'error';
$result['error'] = 'Missing file or internal error!';
}

if (!headers_sent() )
{
header('Content-type: application/json');
}

echo json_encode($result);

?>

You would be better of posting this on a javascript forum
Also php is server side language and javascript is client side, how are you going to convert that?

Hi
I was hoping to set up a hit counter using html or javascript but Ive read a few articles saying this is not possible. If this is wrong does any1 know any good tutorials for a hit counter?

If you have to create a hit counter using a server side language does any1 know any good tuturials for this?

thanks!

small idea.

Log in each page_load in if(!Page.IsPostBack) a line that can be saed in a database. With a query on that DB you can do a count on the page.title (for all or just for the current user?) and show it as a counter.

I used sqlcachedependency with table in sqlserver2005
and it works well but
suddenly I opened page in debug mode and tried to change some
configuration setting for testing purposes while the page is running
and when I pressed ctrl + S to save changes
the oncacheitemremoved event called many time with reason (dependencychanged)
untail the stack overflow exception raised .
where is the problem .
even if the application rebuild it self what is the relation
between what the clr do when i save changes && the oncacheitemremoved .

Hi,

I have a local report running in asp.net 2 reportviewer. When I use the export to excel functionality of the reportviewer control, the numbers are exported as text in excel and I can not apply excel functions on the number fields. Do you know if there is a certain format I can use for excel to know its a number field. I used =FormatNumber(Fields!Balance.Value) AND
=Format(Fields!Balance.Value,"### ### ##0.00") AND
=Format(Fields!Balance.Value,"###,###,##0.00") none working. I removed the format all together and it still didn't make a difference.

Please assist
