DevExpress GridControl Double_Click Storing Data

I have a DevExpress GridControl. I want the Double_Click from a selected row to populate textboxes and radiobuttons that work currently work fine on the page.

The basic setup is 3 txtbox and 2 ckboxes. Those are stored as children and populated in the GridControl after clicking the Save button (all of this works, mind you). Happen I make a mistake and type something wrong. I need to grab that child out of the grid (Double_Click, or anything at this point really), and save that information in the predefined properties so I can populate those txtboxes and ckboxes.

I have looked on the DevExpress site and it's not very helpful. I have tried these things:

And also trying to create a list based off of the row. That didn't work either. Ideas?
