XML

<script type="text/javascript">

function test()
{
  var str="value";
  document.getElementById("hidden1").value=str;
}
</script>

XML

<input id="hidden1" type="hidden" runat="server" />
        <asp:Button ID="Button1" runat="server" OnClientClick="test()"
 Text="Button"
onclick="Button1_Click" />

C#

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Write(Hidden1.Value);
}

Solution 1

1. I think you can use these two in unison easily, i mean If i write some text on a txtbox1 using javascript on client side I can retrieve that using .text from server side (provided the viewstate is disabled for that control).

Could anyone ratify my understanding. i might be wrong too.
