Open the query qryContactsDatasheet in the ContactsDataCopy.mdb database. You should see a result similar to Figure 7-29. Displaying different records or fields is simple. You can use the horizontal scroll bar to scroll through a table s fields, or you can use the vertical scroll bar to scroll through a table s records. In the lower left corner of the table in Datasheet view, you can see a set of navigation buttons and the Record Number box, as shown in Figure 7-30. The Record Number box shows the relative record number of the current record (meaning the number of the selected record in relation to the current set of records, also called a recordset). You might not see the current record in the window if you ve scrolled the display. The number to the right of the new record button shows the total number of records in the current recordset. If you ve applied a filter against the table (see Searching for and Filtering Data, page 272), this number might be less than the total number of records in the table or query.

You might find it easier to use the keyboard rather than the mouse to move around in a datasheet, especially if you re typing in new data. Table 7-6 on the next page lists the keyboard shortcuts for scrolling in a datasheet. Table 7-7 on the next page lists the keyboard shortcuts for selecting data in a datasheet. 253

You can quickly move to the record you want by typing a value in the record number box and pressing Enter or by using the navigation buttons. You can also choose the Go To command from the Edit menu to move to the first, last, next, or previous record, or to move to a new, empty record. You can make any record current by clicking anywhere in its row; the number in the record number box will change to indicate the row you ve selected.

Working with Subdatasheets
Microsoft Access 2000 introduced a new feature that lets you display information from multiple related tables in a single datasheet. In the design we developed in 3 for the LawTrack Contacts sample database, Contacts can have multiple Contact Events and Contact Products. In some cases, it might be useful to open a query on Contacts and be able to see either related Events or Products in the same datasheet window. You might have noticed the little plus-sign indicators in the datasheet for qryContactsDatasheet in Figure 7-29. Click the plus sign next to the second row to open the Contact Events subdatasheet as shown in Figure 7-31.

A subdatasheet doesn t appear automatically in a query, even if you ve defined subdatasheet properties for your table as described in 4, Creating Your Database and Tables. I had to open the Properties window for the query in Design view and specify the subdatasheet you see. Figure 7-32 shows you the properties I set. You can find more details about setting these properties in 4 and in 8, Building Complex Queries.
