if a control in a grid row fires an event it should, or you can make it, fire the grids item command. Inside the itemcommand event you have access to the dataItem in the event args which you can use to go find the other control on the row and do whatever you want to it. I dont recall the event order off the top of my head, but you should be able to handle both events in itemCommand by specifying a CommandName or CommandArgument on the control. I've been working with Java and Android for the past couple months, so the details may be slightly wrong but it should get you going in the right direction. Or if you know what the row index is you can use the gridviews row collection and its column collection to get to the other dropdown.
