openning a particular pdf page in asp.net using .ashx handler

5-Nov-09 1:31

which editor you are talking about ?

If it is just a textbox you can check like this

txtbox keypress="javascript:return checkNosofLetters(this, event);"<br />

function checkNosofLetters(evt)
{
   var e = evt || window.event;
   if(e.srcElement)
      return e.srcElement.value.length < 100;
}

Did you mention

Response.ContentType = "application/pdf"; 
Response.AddHeader("content-length", yourbufferlength);
Response.BinaryWrite(...)

In that case you need to put some commands I guess to the PDF plugin of browser.

I dont know if it is possible or not. But I do think you need to somehow read the pdf in server and create pdf with only the page number that the user wanted to see, loading the PDF in IFrame. Wink | ;)

But in that case there would be postback for every page calls to the server. D'Oh! | :doh:

Are you assigning handler to Dynamic Control On Page Load Event (ie- On Every Postback) ??/

No i am not assigning any handler in page load,
in page load i am just calling the method to create these controls, evrything is in the method itself and that code i have alredy pasted.

Thanks for your quick reply on this.

If you are calling a method in Page_Load it automatically means you are in Page_Load. Wink | ;)

As far as I suggest, add eventhandler in Pre_Init than Page_Load Thumbs Up | :thumbsup:

Rohit,
First clear me that what page u r using .html or .aspx
If U r using .aspx page,then data can be bound to dropdown list from db by using SqlDataSource.
Is it so?
