[CLOSED] Button DirectEvents: How to stop the Click Event from triggering due to certain conditions

[nhg_itd]

Hi,

There is a button than contains a DirectEvents when the button is clicked. But for certain conditions (validation), I would like to stop the event and not call the DirectEvents. Can you advice how to accomplish this?

var ClickTrend = function(grid){
  var index = grid.store.findExact('CheckColumnTrendingList',true);
  if(index >= 0){
    //Do stuff
  } else {
    //Ext.EventObject.stopEvent();                            //Tried this but its not working
    //Ext.getCmp('ButtonTrend').stopEvent();             //Tried this too and its not working
    Ext.Msg.alert("","Please select one item in the Option drop down box to perform a search.");
  }
}

HTML

  <ext:Button ID="Button1" Text="Trend" runat="server">
    <DirectEvents>
      <Click OnEvent="DE_ButtonTrend_Click" Before="ClickTrend(#{GridPanelTrendingList});">
        <ExtraParams>
          <ext:Parameter Name="Clear" Value="false" Mode="Raw" />
          <ext:Parameter Name="SelectedTestList" Value="GridPanelTrendingList.getRowsValues()" Mode="Raw" Encode="true" />
        </ExtraParams>
      </Click>
    </DirectEvents>
  </ext:Button>

Hi,

To stop a DirectEvent, please return false from its Before handler or a respective listener.
