I have an ascx user control and want to store the value of a TextBox on the usercontrol to a hidden item on the user control. I then want to reference the hidden control in the C# code behind to do some validation.

I have this hidden item

<input type="Hidden" id="Hidden1" value="" clientidnode="Static" runat="server">

I want to set the value of this hidden item after the page loads and am trying to use this J Query script

  $(document).ready(function () {
      $("p").text("The DOM is now loaded and can be manipulated.");
      var v1 = $("#<%=TxtCaseNumber.ClientID%>")
      $('#Hidden1').val(v1);
  });

I then use the C# code behind to check the value of the Hidden1 item using 

string s = Hidden1.Value;

No value is being assigned? What am I missing here?

You might want to get the actual value of the textbox 

var v1 = $("#<%=TxtCaseNumber.ClientID%>").val();

  • I also had to correct a setting in the hidden item. I had a typo and type ClientIdNode="static when it should have been ClientIdMode="static". Once those 2 items were corrected it works. – Perry Jun 30 '16 at 11:42

From the info above the problem was resolved by changing a setting in the hidden item to clientnode ="static" to clientidmode="Static" and by completing my code by getting the value of the text box by adding the forgotten .val.
