Remove existing ItemCalculation with Particular ReferenceId from ListCalculator

Jennifer Gilson posted over 12 years ago

Hi,

Is it possible to remove ItemCalculation registered with ListCalculator ItemCalculations collection ?

Or at least change associated formula. When i try to replace formula i get exception "InvalidOperationException: Collection Was Modified".

Here is the sample which throws an exception

var calc = View.ListCalculator.ItemCalculations.FirstOrDefault(i => i.ReferenceId == FormulaId);

if (calc != null)

{

calc.Formula = formula;

}

Please provide sample how to remove registration of the formula or replace formula in the already existing ItemCalculation.

Thanks.
