Determine height of text wrapped in label

[John Baro]

If I have a label (AutoSize = false) with more text than can fit it wraps
downwards.
I need to determine how high the label needs to be to fit the whole of the
text in.
I can then put it into a scrolling panel and scroll it like a textbox.
Any ideas on how to do this or a more appropriate method are muchly
appreciated.

Cheers
JB

Hi, John

you can use Graphics.MeasureCharacterRanges and Graphics.MeasureString to
get necessary measurements.
MeasureString is useful when you don't need high precision - however for big
strings it is not too good. Some people recommend to use always range
function.

Thanks Alex
I wanted to try and avoid that as it is quite complicated and the label
control (generally) does a good job of wrapping its text.
I ended up subclassing the label control, adding a new AutoSize enum and
resizing the control using preferredwidth and preferredheight.
It is reasonably accurate except when I have really narrow labels and will
have to do for now.
