How to access the view-state values in JavaScript? [Resolved]

Use RegisterHiddenField than mixing server/js codes

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    ViewState("code") = "EE"
    Page.ClientScript.RegisterHiddenField("vCode", ViewState("code"))
End Sub

On your javascript:

var vCode = document.getElementById("vCode");
alert(vCode);

The answer is NO, You can access the Hidden field "__ViewState" through JavaScript but it is all encrypted.

If you want to get the encrypted value using JavaScript you can do the below code:-

function GetData()
{
var data=document.getElementById('__VIEWSTATE').value;
alert(data);
return false;
}

There is an alternative way to access the View-State Values form different method:-

Define a hidden field and make sure you set runat=server

<input type="hidden"  id="myhiddenField" runat="server" value="" />

then in your code behind assign any value you want to it

myhiddenField.Value= ViewState["name"].ToString();// or assign any value you want

In your javascript access it like this:

<script type="text/javascript">  
         function test() 
              {
                var name = document.getElementById('myhiddenField').value;
                alert(name)
             }
 </script>

Another way:-

In case for some reasons you don't want to have a server input control you can put the hidden field in a literal tag

<asp:literal id="literal1" runat="server"><input type="hidden" id="myhiddenField" value="{0}"/></asp:literal>

and then assign a value to the literal in codebehind like this

literal1.Text = string.Format(literal1.Text, "somevalue");  // somevlue can be your ViewState value

then access it in javascript as usual

var name = document.getElementById('myhiddenField').value;
            alert(name)

Note: if you are using update panels put the hiddenfields inside the contenttemplate tag of the updatepanel
