Using the Ctrl+drag sequence is the only way to select a group of components that are
contained within another component if you are using the drag method. You can use the
Shift+click method to select components contained within another component just as you
do when selecting components on a form.
Moving Components
NOTE
NOTE
Moving components is a common and fairly simple task. To move an individual component,
simply place the mouse cursor over the component and drag. As you drag, a white rectangle
that represents the component moves with the mouse cursor. When you have the white
rectangle where you want it, let go of the mouse button, and the component will be moved
to that location.
When you move a control via drag-and-drop, the Left and Top properties
of the control are automatically updated.
It’s easiest to move a component by drag-and-drop. If you need finer
control, you can modify the Left and Top properties of the component.
You can also use various alignment options, which I’ll discuss later in
the chapter in the section “Aligning Components.”
If you have the Snap to Grid option on, the white dragging rectangle will snap to the nearest
grid point as you drag.
TIP
If you change your mind while dragging, you can press the Esc key on
the keyboard before you release the mouse button to cancel the drag
operation. The component will return to its original position.
Dragging a group of controls works the same way. After you have a group of components
selected, place the mouse cursor over any one of the controls and begin dragging. The white
dragging rectangle will be displayed for each of the controls in the group. This allows you to
visualize where the group will be placed when you release the mouse button.
