How can I access the content of hidden field, where the hiddenfiled's visibility set to Visible=false in the server side using C#. I am not in a situation to use CSS's display:none instead of Visible=false.

If Visible is false, then the control did not go down to the client, so you cannot directly access it from javascript: it simply isn't there.

Equally, since it is a HiddenField (i.e.<input type="hidden"...>), there is no need to set display:none - it will never be visible, even if Visible is true (although, it will be in the source).

So: either set Visible to true, or e back to the server to get that value.

When you set Visisble=false on the server side it won't actually render the control in the page so there is no way to get the value on the client side.

If you really can't put the value in the page some other way you could do an AJAX request to get the value when you need it?

You can't - these fields are not being rendered to the client side.
