How to get the height of Label control in Winforms

Question

My label is wrapping the text due to the length of the text. The height property returns the correct value only if there is a single line. How can I get the correct height?

Thanks.

Solution: I was creating the label dynamically and checking the height then. Later the panel on which the label was residing was added to a form, changing the panel's font and thus also changing the label's font and height.

Option 1: You can use Graphics.MeasureString or TextRenderer.MeasureText. The second one is probably easier for your purposes.

Option 2: If the label is not growing properly to fit the entire text, make sure that the AutoSize property is set to True.

Option 3: Use a TextBox instead of a Label. Set the ReadOnly property to true, and change the backcolor and border to match a Label. Then, set MultiLine = True. That may give you the same effect, but without whatever bug you are seeing.

Answer 2

The easiest way to get the preferred dimensions of a label is by using Label.GetPreferredSize(Size.Empty). If you wish to get the dimensions constrained by a size, use the same method with a non-empty size: Label.GetPreferredSize(constrainingSize)
