I want to replace the default action (or the view) when a row of a recordset is clicked. I need to add some buttons that are defined with the category of the sensor.

Ex : I have a temperature sensor and a relay. With the temperature sensor I can indentify the sensor and make a measure. With the relay I can identify the sensor, change the state of the relay and make a pulse. For each action I want to have a button. And they are both sensors (same class with different category). They have the same class to show them in the same recordset. If you have another solution I will try them. Thanks
