Have you tried using jQuery? If you haven't you can find any element on the page by a selector. So if you want to find a hidden field called hdnField you would do this:

$("#hdnField").val();

That would return the value of the hidden field.

Hi,

mamtagupta
First i have read <tr> from grid. Then i am reading input tag. I have one checkbox and 2 hidden field in input tag. I want to find one hidden field which is emp_id.

Can you show us some piece of your generated html? jQuery could indeed help you to find what you're after. I suggest you take a look at its selectors: http://docs.jquery.com/Selectors.

Try this jQuery. It will only search for a field that ends with hbEmployee_Id:

$("input[id$=hbEmployee_Id]").val()

The $= section of the selector works well in these scenario's where the id is changed thanks to master pages for example.

Well that piece of JavaScript will return the value of the hidden field. So if you only have one hidden field named that, that piece of code will find it without looping through each row in the table. Make sense?
