Remarks

To assist with data entry, Internet Explorer 5 and later and some other browsers support a feature named AutoComplete. AutoComplete monitors a text box and stores a list of the values that the user has entered. When the user returns to the text box another time, the list of values is displayed. Instead of retyping a value, the user can simply select the value from this list.

Note

Not all browsers support the AutoComplete feature. Check with your browser to determine compatibility.

To control the behavior of the AutoComplete feature for a TextBox control, you use the AutoCompleteType property. The AutoCompleteType enumeration is used to represent the values that you can apply to the AutoCompleteType property.

By default, the AutoCompleteType property for a TextBox control is set to AutoCompleteType.None. With this setting, the TextBox control shares the list with other TextBox controls with the same ID across different pages. You can also share a list among TextBox controls based on a category instead of based on an ID. When you set the AutoCompleteType property to one of the category values (such as AutoCompleteType.FirstName or AutoCompleteType.LastName), all TextBox controls with the same category share the same list. You can disable the AutoComplete feature for a TextBox control by setting the AutoCompleteType property to AutoCompleteType.Disabled.

Refer to your browser documentation for details on configuring and enabling the AutoComplete feature. For example, to enable the AutoComplete feature in Internet Explorer version 5 or later, from the Tools menu, choose Internet Options. Then choose the Content tab. Choose the AutoComplete button to view and modify options for the AutoComplete feature.
