WPF C# - Updating data in usercontrol2 from usercontrol1 update button

SDavisworth asked:

Hello all

I've got a userControl that houses other userControls within tab items. They are made visible and cleared by interaction with various checkbox's on my parent userControl. I've validation and writetodatabase functions in place which works for parent userControl. What I need to have happen is when "Update" (utilizes CommandBinding) button on uC1 is clicked, that all relevant uC data on other tabs are saved to db as well. I've got validation to work but am stumped in saving the data of uC2/uC3/uC4 etc. ... any pointers would be most welcome.
PS I'm trying to keep my uC's as loosely coupled as possible... as well as I'm a beginner and step by step instructions would be great.

Thanks in advance.
