Is it possible to interact with the ASP.NET ViewState using JavaScript? I
would like to be able to access data in ViewState through JavaScript and
also set ViewState data. Not sure if this is the "best:" way to send data
between ASP.NET pages and JavaScript. If anyone has other suggestions,
please feel free to comment.

ViewState is encrypted, so I don't think you would really be able to
retrieve data from it.
You can write out javascript that has your client side variables from the
server, to get those values over.

Hi, Ken
The simplest way is to define the variale as a hidden field runat server
<input type="hidden" runat="server" id="hidValue"/
Then you can access the value both in JavaScript and Code Behind

You could interact with ViewState, but I'd advise against doing so.
The ViewState holds data about the page and the page's controls for
use by the server, it's not designed as a communication mechanism
between client and server (in fact, ViewState is MAC encoded by
default to prevent tampering by the client).
You can certainly create your own hidden fields however and use them
to pass values back and forth, i.e:
<INPUT id="myfield" type="hidden" value="blah" runat="server">
which from the code behind will be of type
System.Web.UI.H tmlControls.Htm lInputHidden.

Ken,
I believe ViewState information is Base64 encoded, so as long as you can
decode it in JavaScript, you shouldn't have a problem accessing the
decrypted form element information, although I've never tried it.

Now the problem is when the page is refresh after 30 secs
the datagrid loses it's values.
I mean it does not maintain it's viewstate.
Why is it?
