Hi,
when you manipulate values of a serverside controls like textbox<asp:Textbox/>,listbox in java script,you cannot retrieve the value in server side (button click).
but when you write same value in a Hidden Field control( <asp:HiddenField/>)) in java script ,you can retrieve the value of the Hidden Field from the server.
Now my question is
how this is possible if all are server side controls only.why ASP.Net behave differently in both cases to retrieves the values and how?
Go to the complete details ...
