Data Entry Form Sample

      

This sample shows how to use different data-bound https://msdn.microsoft.com/en-us/library/aa244728(v=vs.60).aspx (DTC) to edit information in a database.

Behind the Scenes

This sample uses one file: Entry.asp. This file uses several different design-time controls to browse, edit, and navigate through the records in the database.

Recordset DTC.   This control connects the page to the DENTRY table.

Textbox DTCs.   These controls are used to display and edit the First Name, Last Name, Address, City, State/Province, and Postal Code fields in the DENTRY table. Each of these controls is bound to a field in the table.

OptionGroup DTC.   This control is bound to the SEX field in the DENTRY table. Static values of Male and Female are set in the properties of the control. They correspond to a 1 for Male and 0 for Female in the table.

Listbox DTC.   This control is set to be a drop-down list box and is bound to the INCOME field in the DENTRY table.

Checkbox DTC.   This control is bound to the PC field of the DENTRY table. The value of the field is a bit value to determine if the check box should be checked or not.

RecordsetNavBar DTC.   This control is bound to the Recordset DTC to allow the user to step through the records in the DENTRY table.

FormManager DTC.   This control manages the entire form. When the form is first viewed, it is in the Browse mode. There are two buttons visible at the top of the form that allow you to toggle between Browse and Edit modes. When you switch to Edit mode three more buttons become visible and the RecordsetNavBar is hidden. The three extra buttons allow you to Insert, Delete, or Update information in the DENTRY table.

In the FormManager properties dialog box, the Browse and Edit mode properties are set to enable and disable the controls within the form. The Browse mode is also set to be the default mode when you enter this Web page.

In the Action tab of the FormManager properties dialog box, the properties for the buttons are set. Each button performs a different set of actions.

The Edit button will enable the controls on the form, display three buttons for Insert, Delete, and Update, and will also hide the RecordsetNavBar.

The Insert button will call the Recordset.AddRecord method and then call the Recordset.MoveLast method to allow you to edit the newly added record.

The Delete button will call the Recordset.DeleteRecord method to delete the currently selected record and then call the Recordset.MoveFirst method to display the first record in the recordset.

The Update button calls the Recordset.UpdateRecord method to save any changes that have been made to the currently selected record. This button needs to be clicked in order to save any changes that have been made to a new record that has been created using the Insert button.

The Browse button will disable the controls on the form, hide the three editing buttons, and display the RecordsetNavBar.
