  Busy cursor or Processing status when Page isn't Posted or Reloaded?

  Sep 04, 2019 01:04 PM|Mickexl|LINK

  Hello,

  I have a Web Forms page that creates a CSV file after user has pressed button. It would be nice to give user a busy cursor or status text that tells processing is on.

  The problem is that I don't Post or reload that page so how to implement "End of processing" event from Code Behind to User Interface? Otherwise User Interface's Busy cursor is on or status text "Processing..." after CSV file is done.

  Ideas or samples how to implement this?

  Best regards,

  Michael

  Hi Michael,

  Mickexl

  how to implement "End of processing" event from Code Behind to User Interface?

  After you generated CSV file, you can call JavaScript function from code behind to let user know the processing is finished, like below.

  protected void btn_createcsv_Click(object sender, EventArgs e)
  {
      //your code logic of generating CSV file
  
      ClientScript.RegisterStartupScript(this.GetType(), "UpdateUI", "myfunc()", true);
  }

  On JavaScript client side

  function myfunc() {
      //your code logic here
      //update UI
      alert("End of processing");
  }

  Test Result

  Hello,

  Thanks for your answer. Unfortunately I have to call  ClientScript.RegisterStartupScript(this.GetType(), "UpdateUI", "myfunc()", true); from User Control (.ascx.cs) and javascript function is placed to User Control too (.ascx) but calling fails.

  No error messages. Somehow User Control seems to be different that e.g. Web Forms Page because in Page this works.

  So, how to get this work in User Control too?

  Thanks,

  Michael
