Help,ownerdrawn ListView not font-sizeable

[Martin Streller]

Hello,

The code below represents a simple ownerdrawn,
Listview class in C#. Its purpose is to avoid
the flicker of the MS ListView. So I can't fall
back to their one.

Does anybody know why I cannot change the
size of the ListView's font (ListView.Font)
from e.g.
Microsoft Sans Serif; 8,25pt
to e.g.
Microsoft Sans Serif; 15,75pt ?
Can someone help ?

What I noticed is, that the text displayed is
growing as intended.
However, the rectangle returned by
ListViewItem.GetBounds(ItemBoundsPortion.Entire)
always remains fixed. That is, it remains for ever on the bounds
corresponding
to 8,25pt .

When compiled and being run, the blue rectangle around each item
displays
the entire item bounds. Pls, increase the font size, compile and run
again.
You'll then see the mess.

Regards, Martin
