Goto specific word in a PDF or PDFS file and highlight the word (in javascript or C# ) in webform

hi, i have provided the code plz giude me if you can..
thankyou

Obviouly i have tried many things and didnt got proper answer, thats why i am here. Below code jumps to the page number when i click on page number in the div. From the below code to can try to get page number from Database and jump on the apprppriate page..

<div>

<div width="50%" id="dvPdf">
<iframe src="http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#page=5&zoom=auto,-169,394" width="500" height="500"></iframe>

</div><div style="float:right">(note DIC adds the space in java script below:)
1
20
30
61
</div>
<script type="text/javascript">
function scrollPdf(v) {
document.getElementById("dvPdf").innerHTML = '<iframe src="http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/pdf_open_parameters.pdf#page=5&zoom=auto,-169,394#page=' + v + '" width="500" height="500"></iframe>';

}
</script>

</div>


Now the challange is how to get the word index after jumping to page.

Before this javascript technique i have also tried making a pdf file using itextshare and highlighting text with hardcode coordinate value. Also getting page number dynamically using below code.

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
process.StartInfo = startInfo;
// startInfo.UseShellExecute = false;
startInfo.Arguments = "/A \"page=20\"";
startInfo.FileName = @"C:\\Users\\123\\Desktop\\PDF HIGHLIGHT\\03june\\sample.PDFS\";
process.Start();

// Process.Start(startInfo);

I hope i have done somethning sensible. Please guide me if theres something wrong.

Thankyou
