UserControl in DataGridView cell

Hi!:

I have created a user control with one textbox and a button, and I need
this control to be loaded in the datagridview. In a cell the value is the
text property of the textbox. I have seen some examples but with the
keyboard and the focus have problem. (There are answers in others threads
by Mark Rideout and Zhi-Xin Ye, but not a complete example running with
the keyboard).



Any complete code example?



Thanks in advance
