In a browser, you can switch to design mode to see the text supplied for the EmptyZoneText property displayed in the empty zone. For details on how to change page display modes, see Walkthrough: Changing Display Modes on a Web Parts Page.

Remarks

The text in the EmptyZoneText property appears when there are no controls in a zone, and the zone is in one of the personalization modes, such as edit, design, or catalog mode.

Note

When a zone enters one of the personalization modes that would allow personalization changes to be made to the zone's contents, the WebPartManager control sets the WebPartDisplayMode.AllowPageDesign property value to true on the display mode object referenced in its WebPartManager.DisplayMode property.
