Set Tab Order of Controls on a Page
In the Forms Designer, right-click a page, but not a control, and then click Tab Order.
Select the name of the control that you want to reposition in the tab order.
Click Move Up or Move Down.
Note You can also set the tab order by changing the TabIndex property. The tab index of the first control in the tab order is 0; the tab index of the second control is 1, and so on.
