Answer 1

Basically, you need to descend from the base class DataGridViewColumn and create your own visual display.

See here for an example of how to do this:

Answer 2

只需从Microsoft获得DataGridViewNumericUpDownColumn 。

Answer 3

Obviously you can't inherit form TextBox as it is not object that inherits from DataGridViewColumn.

On the other hand, you can inherit from any object that inherits from this object.

Note that when using your new Column class, you must cast DataGridView.Columns[index] to it, otherwise you won't see any of its properties or methods. Or you can also create new class from DataGridView that does this in new property.
