What sets the flag so that the DataProcessor knows to udpdat

I am trying to implement a Menu that allows the user to update a value associated with a cell which is then reflected by changing the cell color (i.e. the value will be a value separate from the text associated with the cell). I guess that this will have to be in the form of userdata. My question is, do I have to call an API that will trigger the DataProcessor to know that the grid was updated? If so, what API?



Thanks

If you are changing some value in grid by inner API and want to inform dataprocessor about updated you can use
    dataprocessor.setUpdated(rowID,true);

rowID - id of row, where cell was changed
