Gets or sets a value that determines whether conditional formats will occur automatically.
Assembly: Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)
When theproperty is set to false, existing conditional formats will not be re-evaluated. Any previously applied conditional formatting will still be visible, but will not be updated as cell values or AppliesTo ranges are changed.
Set this property to true to configure a rule completely before evaluating it. This can result in a performance increase if the range over which the condition is applied is large.
