public void Protect( Nullable<bool> allowEditObjects, Nullable<bool> allowEditContents )
When a Chartsheet is protected without a password, the end user may unprotect the Chartsheet in Excel without having to supply a password. To programatically unprotect a Chartsheet, one may use the Unprotect method.
The optional parameters are used to update the property values of the Infragistics.Documents.Excel.Charts.ChartsheetProtection instance from this Worksheet's Protection property. If the parameter is null, the current value of the associated property will be retained; otherwise the property will be updated with the specified value. For example, if the Infragistics.Documents.Excel.Charts.ChartsheetProtection.AllowEditObjects is currently true and the allowEditObjects is null, then the property will continue to be true but if the allowEditObjects is false the Infragistics.Documents.Excel.Charts.ChartsheetProtection.AllowEditObjects will be changed to false.
Note: If IsProtected is already true, the method will be ignored.
