.SetBounds will set the Left, Top, Width, and Height properties all at once.
Use SetBounds to change all of the component’s boundary properties at one time. The same effect can be achieved by setting the Left, Top, Width, and Height properties separately, but SetBounds changes all four properties at once ensuring that the control will not repaint between changes.
This is the general form of SetBounds:
Calling SetBounds does not necessarily result in the Left, Top, Width, and Height properties changing to the specified values. Before the properties are changed, the AutoSize or Constraints property may limit the changes, and an OnCanResize (or OnConstrainedResize) event handler may change the new values. After the control’s Left, Top, Width, and Height properties are changed, SetBounds generates an OnResize event.
In the next section, we will show you the example of SetBounds for each one of them.
