I have a WebDataGrid where the first field uses a dropdown provider.  Whenever the user selects an item from the dropdown, I need to automatically select an item in another dropdown field and set 2 other fields, depending on what was selected.  I need to be able to get a record from the database for the selected item to determine what the other fields should be.  Is there a way to call a server method when the user selects from a dropdown where I can determine what was selected and be able to set the other fields?  If not, what is the best way to accomplish this?

Thanks,

Jeff
