Example

This example JavaScript code maps the event for the Spread on the client side.

<script lang="javascript" type="text/javascript">
    window.onload = function () {
      var spread1 = document.getElementById("<%=FpSpread1.ClientID %>");
      if (document.all) {
        // IE
      if (spread1.addEventListener) {
      // IE9
      spread1.addEventListener("ActiveCellChanging", cellChanging, false);
      } else {
      // Other versions of IE and IE9 quirks mode (no doctype set)
      spread1.onActiveCellChanging = cellChanging;
      }
      }
      else {
      // Firefox
      spread1.addEventListener("ActiveCellChanging", cellChanging, false);
      }
      }
    
    function cellChanging(event) {
      var r = event.row;
      var c = event.col;
      if (r==1) event.cancel = true;
    }
</script>
