X = Math.Abs(( int)Math.Ceiling(textSize.Width * Math.Cos(_radians))) Int y = Math.Abs(( int)Math.Ceiling(textSize.Height * Math.Cos(_radians))) int x = Math.Abs(( int)Math.Ceiling(textSize.Height * Math.Sin(_radians))) These are the components of the // width and height after rotation. When you rotate the text, the width and height will now have an X and a Y component // because they no longer fall along the X or Y axis. Protected override void OnPaint( paintEventArgs) Most of the work takes place in the OnPaint event. An Angle property is added to store the text angle. Most of them override the base class to allow the text to be updated when a property changes. The labels will also update when the form is resized. When started, the form appears like the following:Īs the controls are updated, the labels will also update accordingly. The top label is anchored on all four sides and the bottom label has the docking set to Fill. It has two RotatedLabels that can be updated using the controls on the left. The angle rotates the text in a clockwise direction.Ī demonstration project is included in the downloads section. In the Properties window, you will find an entry for the Angle, as shown highlighted below. The control can then be used exactly like a standard Label control, with one difference. Then it can be dragged-and-dropped onto a form.

In the case of the example code, you will find it in the Toolbox under the Controls Components. It is recommended to add it as part of a control library. Since the control was designed to feel built-in, its use should be intuitive. That is, there isn't a control that allows for rotated text and that obeys the Anchor, Dock, TextAlign, and AutoSize properties. There are several examples online of how to produce basic rotated text, however, there doesn't seem to be a fully developed control for doing this. NET Framework does not seem to have a built-in control for displaying rotated text. The text in each label is set to a different angle, text alignment, and font. It will exhibit appropriate behavior for the settings of the Anchor or Dock properties.īelow are some examples of the label. With these features in place, the control will resize itself and align the text automatically. It allows the user to set the text, angle of rotation, text alignment, and auto-size properties in the designer. The control reproduces the behavior of the built-in Label control but allows the text to be rotated. NET Framework control for adding rotated text to a form.
