As you build your application, you might find it useful to place some data in your tables so that you can test the forms and reports that you design You might also find it faster sometimes to add data directly to your tables by using Datasheet view rather than by opening a form If your table is empty, Access shows a single blank row when you open the table or a query on the table in Datasheet view If you have data in your table, Access shows a blank row beneath the last record You can jump to the blank row to begin adding a new record either by choosing the Go To command from the Edit menu and then choosing New Record from the submenu, by clicking the New Record button on the toolbar, or by pressing Ctrl+plus sign.

Access places the insertion point in the first column when you start a new record As soon as you begin typing, Access changes the record indicator to the pencil icon to show that updates are in progress Press the Tab key to move to the next column If the data you enter in a column violates a field validation rule, Access notifies you as soon as you attempt to leave the column You must provide a correct value before you can move to another column Press Esc, choose Undo Typing from the Edit menu, or click the Undo button on the toolbar to remove your changes in the current field Press Shift+Enter at any place in the record or press the Tab key in the last column in the record to commit your new record to the database You can also choose the Save Record command from the Records menu.

If the changes in your record violate the validation rule for the table, Access warns you when you try to save the record You must correct the problem before you can save your changes If you want to cancel the record, press Esc twice or click the Undo button on the toolbar until it appears dimmed If you want to use the Edit menu to undo the current record, you must choose Undo Current Field/Record from the Edit menu until that menu item appears dimmed and changes to Can t Undo (The first Undo removes the edit from the current field, and choosing Undo again removes any previous edit in other fields until you have removed them all) Access provides several keyboard shortcuts to assist you as you enter new data, as shown in Table 7-8 258.

Building Data Access Pages To further customize the page, you should correct the captions in the two navigation bars as you learned to do earlier. If you want to allow the user to update the data, you must set the AllowAdditions, AllowDeletions, and AllowEdits properties of each group level to True and define the Unique Table for the qryRptFacilityRooms section. If you don t allow edits, then you should remove the New, Delete, Save, and Undo buttons from the navigation bars. You can find this converted and modified report saved as dapXmplFacilitiesAndRoomsRpt in the sample database.

Although you can certainly create many of your data access pages by using a wizard or by converting existing forms and reports, you ll need to create some data access pages from scratch using the design facility. For example, the Housing Reservations application has a form that lets you edit records from tblFacilities and related records in tblFacilityRooms, as shown in Figure 27-35.

However, because this form has a subform, you cannot convert it directly into a data access page. (The Save As conversion facility converts the outer part of the form to edit facilities but doesn t convert the subform.) You could use the wizard to create a data access page that groups on data from tblFacilities and displays related data from tblFacilityRooms, but the wizard doesn t have the ability to display the room information in a tabular format. The only solution is to build what you need yourself.

You can certainly select the Pages button on the Object bar in the Database window and double-click the Create data access page in Design view link to get started, but it s useful to first pick at least one of the tables you want to use as a data source. When you do this, the data access page designer opens the field list with the data source you selected already expanded. 1055

Remove can be called on a single XAttribute as well as on an IEnumerable<XAttribute>. Calling Remove on the latter results in all the attributes within the IEnumerable being removed from their associated elements.
