I have a simple Form with a DataGridView; in VS2005 designer I
change the Form's font size to 9, 10 (or more) points.

When editing a text cell the TextBox editing control seems not have
sufficient height: characters like 'g' are bottom cutted and text is
not full visible!

Is DataGridView text editing "Microsoft Sans Serif; 8,25pt" only "oriented",
or am I missing something?

thanks

Did you also change the DataGridView's font property?

Yes, the problem remains!

The strange thing is that some Fonts (like Microsoft Sans Serif) suffer this
problem, other (like Tahoma) no. I expect a controls like DataGridView
are Font safe (and agnostic too).

In a real application where user can choose the font she/hr likes, this is a
problem!

Any workaroud?

One thing you can try is, in Form.Load (or anytime after the font was
resized), to call:

this.dataGridView1.AutoResizeRows();

done... the problem is still there! it is not a cell painting problem, but
an editing one;

I found that forcing (e.s. in the 'EditingControlShowing' event)

( (TextBox) ( dataGridView1.EditingControl ) ).AutoSize = false;

seems to be a workaround, but I'd prefer not modify the DataGridView
positioning/sizing text editing preconditions (I have manually calculate
the right Height);

this is the same problem of TextBox'es with BorderStyle None: increase the
font
(at least Microsoft Sans Serif) and Text like "gggg" is not full visible;
you can change the
AutoSize property to false and solve the problem, but you loose the "auto
Height sizing"...

Summing up it seems a TextBox problem (from which
"DataGridViewTextBoxEditingControl" derives),
a bug with some fonts when BorderStyle is None
