Property Value

true if an automatic postback occurs whenever the user presses the ENTER or the TAB key while in the TextBox control; otherwise, false. The default is false.

Use the AutoPostBack property to specify whether an automatic post back to the server will occur whenever the user presses the ENTER or the TAB key while in the TextBox control.

NoteNote:

If the TextBox control's parent container contains a button marked as the default button (for example, if the container's DefaultButton or DefaultButton property is set), the default button's Click event is not raised in response to the automatic postback.

This property cannot be set by themes or style sheet themes. For more information, see ThemeableAttribute and Introduction to ASP.NET Themes.

The following code example demonstrates how to use the AutoPostBack property to automatically display the sum of the values entered in the text boxes when the user presses the ENTER or the TAB key.

Security noteSecurity Note:

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview (Visual Studio).
