DotNet: HtmlInputHidden Control

• juliusfenata / 204 / Thurs, 18 Jun 2009 11:46:00 GMT / Comments (0)
• Okay,
  
  I have pass new value from client to server, like this:
  
  <script language="JavaScript">
  function JSGenerateArticleID()
  {
  HiddenValue.value = "test";
  }
  </script>
  ...
  <input id="HiddenValue" type="hidden" runat="server">
  
  Then, I need to use this value on Code Behind, like this:
  
  protected System.Web.UI.HtmlControls.HtmlInputHidden HiddenValue;
  ...
  private void btnAdd_Click(object sender, System.EventArgs e)
  {
  clsArticle m_oArticle = new clsArticle();
  m_oArticle.InsertArticle(HiddenValue.Value); // Not Working
  BindingDataGrid();
  }
  
  Why after I have web-controls HiddenValue the Value is still null? Or,
  Server-side did not recognize HiddenValue?
  
  ps: What is relation between this control with AutoEventWireUp="true"?
  
  Thx,
  Julius F

  Hi Julius,
  
  You have to pass the new value from client to server separately, the Label
  element won't do it for you. There is a number of ways for doing this, most
  common one is via a hidden <input> element.
