.NET Forum / Windows Forms / WinForm General / February 2007setting Font property of Label control in code
This is a very basic question here. I must be missing something here. At run time, I am trying to set the text of the label control bold. lblMyLabel.Font.Bold = true; does not work since it's read only (why why why why why). Thank you. Hello David, >At run time, I am trying to set the text of the label control bold. > >lblMyLabel.Font.Bold = true; > >does not work since it's read only Use a line like this instead: label1.Font.Bold = new Font(label1.Font, FontStyle.Bold); Oliver Sturm  Signaturehttp://www.sturmnet.org/blog > Hello David, > [quoted text clipped - 10 lines] > Oliver Sturm > --http://www.sturmnet.org/blog Thank you. I can't think of a rhyme or reason why Font.Bold property should be read only. Can you? Hello David, >Thank you. I can't think of a rhyme or reason why Font.Bold property >should be read only. Can you? Well... sure ;-) The whole Font handling goes back onto Windows resources outside .NET. On the API level it's simply not possible to set a property Bold on the font - after all, for a lot of fonts it's a different font resource that is being loaded for bold or non-bold display. Check your Windows\Fonts folder and you'll see that there are several arial*.ttf files - one of them is the bold version of Arial. Of course the .NET API could theoretically hide that detail from you and make the Bold property writable nevertheless. But they decided not to go that way and I can understand why - the way things are, the user of the API understands that he's triggering what may be a costly operation. Otherwise it would have seemed like switching the Bold flag may be a trivial thing without a lot of overhead.
