Property Value

Type Default Description

true to hide the panel’s content; false to preserve the panel content being displayed.


Set the HideContentOnCallback property to true, to not display the panel’s content during callback processing.

If the HideContentOnCallback property is set to false (the default behavior), the panel’s content is displayed while a callback is being processed on the server side. In this case, the panel content is covered with a specific Loading Div element whose style settings can be defined via the CallbackPanelStyles.LoadingDiv property.
