I'm having a 'small' problem with a DataGrid control. I'm using template columns, with buttons and textboxes. I've managed to handle to the buttons' events, but I can't interact with the controls (except for handling the click event). I want to be able to press a button, and then write the current row index to a textbox in the same cell. I can write the index to an exterior textbox, but I can't access the '.Text' property of the textbox.

Can anyone help me?
