You can use client-side scripting in Spread to get the Update button and map your own click event for it. This allows you to perform client-side validations before the data gets posted to the server. If it succeeds, then the Update postback occurs. The following code sets up this validation.

JavaScript	Copy Code
<script language="javascript"> function window.onload() { var updbtn = FpSpread1.all("FpSpread1_Update"); updbtn.onclick = test; } function test() { if(succeeds) doPostBack(FpSpread1.id, "Update"); } </script>

JavaScript

Copy Code

<script language="javascript">
  function window.onload()
  {
    var updbtn = FpSpread1.all("FpSpread1_Update");
    updbtn.onclick = test;
  }

  function test()
  {
    if(succeeds)
      doPostBack(FpSpread1.id, "Update");
  }
</script>
