This property controls which object the user will make active if they press the TAB key. Each object that can be activated by moving from object to object will have this property. The objects are in order from 1 to the appropriate number of objects. Generally this value is automatically maintained. It is incremented automatically each time a new object is placed on the form or through the use of the Tab Order Property Editor.
This property can be changed during runtime and accepts any positive integer up to the maximum number of objects that have this property.
