How to highlight first text of a pdf document within an iFrame?
<p>I am making a ASP.Net(VS 2010) website where I have a pdf document of around 2500 pages and I have already separated these pages to each single pages. Then I have stored each page's text to a mysql database.</p>

<p>Now, I have a search box with a button on an ASP.Net page. When users input some text and click the ASP.Net button, then it goes to check the search text with mysql database and if match found(I have also put pdf file name with the database), then it shows related pdf pages with iframe, within a gridview. Then if the users are wanting to search any text within the iframe, then they just press "Ctrl + F" key of their keyboard and adobe reader shows(by default, adobe reader is being shown with the iframe, since I am having adobe reader installed with my development computer) a search box inside the iframe and users do the searches.</p>

<p>Everything is working nicely up to this. But, I am wanting to highlight the text which users had previously entered with the asp.net search text box. And for this purpose, I am also adding the search text with the query string, but I am unable to highlight the first occurrence of the searched text with the pdf file which is being displayed within the iframe.</p>

<p>Please Note: This highlighting will be just a temporary highlighting and after that users will use adobe reader's search box to find other texts.</p>

<p>Please help me in this regard and oblige me thereby.</p>
