Getting row values from the grid after selection and deselection is completed

This is the best grid I've ever seen. Welld one. I've got a problem. I'm using the grid for multi selections. I haven't come a cross a event or property for deselecting a row. I'm using the following to get the value for the selected row.

//Getting the row that is selected
iRowSelection = src.getSelectionProperty("index");

//Return the value of the selected row
sRefNumber = src.getProperty("data/value",iRowSelection,2);

All these values are stored into an array. So for adding the values to the array, isn't a problem. The challange is when you want to deselect a row. I'm using the "selectionChanged", event.

Could you please help me?

Thanks in advance
