You have a large number of fields that you need to display on a form. If you place them all on the form at once, it looks too complicated. You need some way to group them by category and display only the ones that correspond to each category as the user works through all the groups.
Access 97 introduced the native Tab control, which is useful for organizing information into multiple pages. Simply organize your fields into categories, creating one page on the Tab control for each category.
Load 02-05.MDB and open frmMain. This sample form (shown in Figure 2-8) contains a Tab control. By clicking on a tab, you cause one of the four possible pages of the form to be displayed in the Tab control section.
To create your own version of a multipage form, follow these steps:
Create the table and/or query on which you want to base your form (tblSample in 02-05.MDB). Make sure your data includes a primary key (ID in tblSample).
Open your form (frmMain in 02-05.MDB) in design view. Insert a Tab control on the form.
Set at least the properties shown in Table 2-3 for the form itself.
tblSample (or the name of your table or query)
Right-click on the Tab control to add two more tabs, so that there are a total of four. Figure 2-9 shows the Tab control with the right-click menu options. Note the other Tab control options that are also available from the right-click menu. Give each tab one of the following captions: Times, Calendar, Books, and Travel.
Add controls to each tab on the Tab control. Note that as you select each tab, the background turns dark. This will cause the controls dropped on that page to appear only on that page.
To create a control that appears on all of the pages, drag the control from the Field List to the form, not the Tab control. If you then drag it from the form to the Tab control, none of the tabs will be selected. This will cause the control to appear on all of the pages. The Name text box will be visible on every page of the Tab control.
Set the Cycle property of the form to Current Page, so that you won't move from record to record by tabbing around the form. (See The Solution in Recipe 2.3 for more information on the Cycle property.) To move from page to page on the Tab control, press Ctrl-Tab. Ctrl-Shift-Tab will move you backward from page to page on the Tab control.
Use the View Tab Order dialog to set the tab order for the controls on your form. To set the tab order inside of the Tab controls, right-click on the page of the Tab control where you want to set the tab order, and choose Tab Order. This will load the dialog shown in Figure 2-10, where you can change the tab order for the individual controls on that tab page.
There are three other methods that you can use to create multipage forms, but each of these methods requires more work than using the Tab control:
You can create a continuous form with page breaks in between the pages. If you open the form in dialog view, the user will be prevented from maximizing the form. You can write code utilizing the GoToPage method of the form to navigate from page to page.
You can use multiple subforms, placing each of the subforms on the main form and setting all but one of them to be invisible. In the AfterUpdate event of the option group, you can make the current subform invisible and the new one visible. This method can be cumbersome because working with long multipage forms can be awkward. This method also consumes more system resources than the method shown in this solution.
You can create one subform control and, in reaction to pressing buttons in the option group, change the SourceObject property of the subform control. This is a very "neat" solution, because there's only one subform on the main form (as opposed to four in the previous alternative). The drawback here is that changing the SourceObject property is quite slow.
