Question

I would like to set my ListBox.Width property so that it is no wider nor narrower than needed, in order to display the items in it. There is a margin of a few pixels between the left of the ListBox and the start of the text – I would like there to be a similar margin on the right. (i.e. there shouldn’t be a large gap, and the letters shouldn’t be touching the right edge).

Given that I’m not sure how many pixels a given string will be, I’m not sure how to calculate this width.

Answer 1

I believe you’re looking for the MeasureString method of the Graphics class.

Try this:

Graphics graphics = this.createGraphics();
SizeF mySize = graphics.MeasureString("Ahoy there", this.Font);

Hope this helps!
