Pass data from textbox in USERCONTROL to Datagridview in another USERC

Question

I AM WORKING WITH USERCONTROL FOR THE FIRST TIME. MY CASE IS: I have 2 USERCONTROL in a Form (FORM1), where the USERCONTROL1 contains several Textboxes and a second USERCONTROL2 contains a datagridview. If you can help me with the case, how can I pass the data from the textbox to the datagridview. And if you can load the data from the datagridview to the Texbox by selecting a row from the datagridview. Thanks in advance.
