Remarks

The ReportTabClosing event enables you to respond to closing a report tab in the Web Report Designer. When implementing a handling function, use the objects passed as parameters. The first parameter passes the event sender that is the ClientReportDesigner object. The second one is an object with the following structure.

• ReadyToClose
  Specifies the JQueryDeferred object that when resolved, forces the report tab to be closed.

• Handled
  Specifies whether or not the event was handled.

• Tab
  Specifies the report tab currently being processed.

The code sample below demonstrates how to use this event to prevent closing a specific report tab.
