Changing the Label Width Property of the Panes
With the default settings, each pane is set to Use Form Defaults to determine the Child Labels settings for the controls it contains.
In this example, then, the Label Width property for controls placed in this pane is not 120 (that is, the value in the Label Width field is ignored), but is based on form settings.
If no width is set at the form level, each vertical pane will align its controls so that all the fields it contains are vertically aligned, though their labels are of differing widths. This is done on a pane-by-pane basis, so that the fields on different panes won’t necessary be vertically aligned.
In this section, you will modify the Child Label properties at the pane level so that all controls on the form have their fields vertically aligned. To do this, you will set the label width (in pixels) for all fields to a length sufficient to contain the longest label. In addition, you will set the label position property to left instead of top so that control labels appear to the left of the control.
Modifying the Form Level Child Labels Properties
It is good to have the width for labels same as that of the control labels.
