Hi,

 

What expression would I use on my display form to suppress the display of the sub-list, if there are no related items in the sub-list.

 

My lists are as follows:

 

Credit Card - Primary List
Credit Card Transaction - Sub-List

 

Thanks
Sandy

  Hi Sandy.

  1. Get the webpart id of yout sublist webpart
  2. Go to BEHAVIOUR -> Visible Expression
  3. Insert this code into Expression Builder

      Code:

   

  var webpartId="your webpart id";
      var webpartSelector = "[ard-webpart-id=" + webpartId + "]";
      var gridController = jQuery(webpartSelector).data('Controller');
      var grid = gridController.InstanseData.GridControl;
  
      return grid.GetSpCsrRenderCtx().ListData.Row.length > 0 ;
