c# - Fit Label size to drawn text -

i'm using label display progress user. occurs many times , partly user-defined text changes every time.

problem: should know if drawn text bigger label's size.

i tried approach:

using (graphics g = lbl.creategraphics()) {     sizef size = g.measurestring(lbl.text, lbl.font);     // change size of label if small } 

but slow , uses lot resources when calling @ every update.

so there way find out when drawn text bigger label?

edit:
stated hans passant, autosize it.
sorry, didn't other controls below label has move then.

it seems there no other way it.
have use above solution:

using (graphics g = lbl.creategraphics()) {     sizef size = g.measurestring(lbl.text, lbl.font);     // change size of label if small }
