After selecting the Polyline control on the control bar, use the mouse to add points one after another on the form. Double-click at the last point to complete the drawing. If you forget to double-click at the point you wanted to make the last point, double-click at the position of the last point added to complete the drawing.

You can modify the shape of the Polyline (Polyline) control even after it has been created. When you move the mouse to each of the points below, the mouse will display a + sign. Drag and drop each point to modify the shape.

You can also add, delete, or insert points after creating a Polyline control using the Points property. The Points property has the following format:

X coordinate of point 1, Y coordinate of point 1, X coordinate of point 2, Y coordinate of point 2, ... X coordinate of final point, Y coordinate of final point,

Example: If there are four points

465,240,447,256,430,256,430,290

If you want to add, delete, or insert points, edit the Points property directly.

Polyline control can draw Bezier curves in addition to straight lines. For instructions on how to draw Bezier curves, see "Editing Bezier curves".

Polyline control can be rotated by binding. The rotation angle is set with Angle. The center of rotation can be set with the RotateX/RotateY properties, or by moving the center handle below with the mouse.

Rotation using the Angle property occurs at runtime, not while editing in Panel Editor.

2D shape controls have a SwitchValue property that switches between ON/OFF when pressed with the mouse.

1) When the value changes, the OnSwitchChanged event occurs.

2) You can bind a tag to SwitchValue to set the tag's value to ON (TRUE) or /OFF (FALSE).

3) The SwitchType property determines how the SwitchValue changes when the mouse is pressed. The SwitchType property can be selected from the following five types.
