Yes, you can. Just get the document id and make it's property visible true or false.

Use
panel.ClientId to get the client id which is rendered to the browser. Pass it to hidepanel and showpanel javascript function when needed.

To hide panel use

function hidePanel(objId)
{
   document.getElementById(objId).style.display = "none";
}

function showPanel(objId)
{
  document.getElementById(objId).style.display = "block";
}

Hope you can make it yourself now easily. Rose | [Rose]

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(...)

now i need to move to particular page when user select the page number.

ie there are 8 pages in that pdf document i provide the link to the page number nearby. where user click page number 3 the document should display the page number 3 content

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:
