event.getRenderable()

Classic Servoy

is there a sample available for the use of

event.getRenderable()

I don’t think there is sample code attached yet, but to give a small example:

function onRender(event) {
	var _element = event.getRenderable();
	
	if (_element.getName() == "btn_edit") {
		var _record = event.getRecord();
		_element.enabled = (_record.is_active);
	}
}

The result is that the “btn_edit” is only enabled for active records.

Did you test this code in the latest version (6.0.0 b3 - build 1210) ?

When I use the method :

function onRender1(event) {
	
	   var _element = event.getRenderable();
	   
	   if (_element.getName() == "pers_achternaam") {
		   /** @type JSRecord<db:/udm/test1> */		   
	      var _record = event.getRecord();
	      if (_record.pers_achternaam == 'M.' ){
	      		_element.enabled = false;
	      }
	      else {
		      	_element.enabled = true;
	      }
	    	  
	   }
}

I get the following error for each record in the form :
(Line 27 is var _element = event.getRenderable():wink:

You’re right, unfortunately there is an issue with getRenderable in b3.
R&D is already aware of this and working on fixing it.
